Molar pregnancy and IVF
Name: Tony A
Can a woman that has had molar pregnancy twice within 4 years and undergone chemotherapy be advised to go for IVF?
Author
Answer:
It is possible
Molar pregnancy or hydatidiform mole — is a benign tumor that occurs in the uterus. It starts when an egg is fertilized, but instead developing into a normal, conceptus + placental tissue, the placenta tissue develops into a mass of small cysts. Here, the root system (trophoblast) of the embryo which under normal conditions develops into the placenta that connects the baby to the mother. With molar pregnancy, the roots of the trophoblast (chorionic villi) undergo cystic degeneration and when the woman bleeds, these cystic structures are passed in dark blood, giving rise to the common description of “white currants floating in red currant jelly”.
The condition usually presents with one or more of the following:
- Vaginal bleeding in the first trimester
- Very high beta hCG levels early on in pregnancy
- Exaggerated pregnancy symptoms and pernicious intractable vomiting (hyperemesis gravidarum)
- Rapid (often painful) enlargement of the early pregnant uterus
- Ultrasound evidence of a typical “snow storm pattern)
A molar pregnancy can have serious complications. It can become invasive (an invasive mole or chorioadenoma destruens) and permeate the uterine wall or it can (albeit rarely) develop into a rare form of cancer known as choriocarcinoma.
Molar pregnancies are rare (about 1:2000 pregnancies) and having occurred.it infrequently (<1:1000) recurs in the same woman. It is at least twice as common among Asian women. On rare occasions (1%) a twin pregnancy will comprise of a normal baby and a mole. In about 20%-40% of cases the healthy baby will survive to delivery.
There are two types of molar pregnancies: a) the complete molar pregnancy: Here there’s no embryo or normal placental tissue is present. b) . A partial molar pregnancy, there is a developing embryo present but it is abnormal and non-viable, but there can be some “normal” placental tissue present as well.
“Complete Hydatidiform Molar Pregnancies” occur when an egg that has no chromosomal material (anuclear) is fertilized by a sperm and thereupon divides in two and propagates haphazard tissue growth. Like normal pregnancies, the complete mole has 46 chromosomes (two sets of 23), i.e., it is diploid. However, unlike with normal fertilization, where one set of chromosomes comes from the mother and the other set from the father, both sets of chromosomes come from the father in the case of a complete molar pregnancy. This results from duplication of a sperm’s chromosomes after it has fertilized an “inactive” egg. Since an embryo that has a YY karyotype is not viable, the chromosome gender of the complete molar pregnancy is invariably XX (female). Accordingly, with IVF, if one selectively only transfers only male (XY) embryos, the possibility of a complete molar pregnancy can be virtually eliminated.
A “Partial Molar Pregnancy” on the other hand, most often results from an egg being fertilized by 2 separate sperm, such that instead of the resulting embryo comprising 46 chromosomes (23 from the egg + 23 from the sperm), it instead has 69 chromosomes (23 from the egg + 46 from 2 separate sperm). However, it can also happen where one sperm fertilizes an egg, but one group of 23 chromosomes duplicates …again resulting in 3 groups of 23 chromosomes (triploidy)…..for a total of 69 chromosomes. Thus with partial moles, the sex chromosome configuration will be XXY or XYY. Partial moles can thus be avoided through selectively fertilizing an egg by intracytoplasmic sperm injection (ICSI), where a single sperm is injected, and thereupon performing PGD on the embryo(s) to exclude triploidy.
Persistent trophoblastic disease refers to the situation where following treatment to remove a molar pregnancy some molar tissue is retained and starts to grow again. It occurs in 8-10% of molar pregnancies. In such cases the woman will usually need to undergo chemotherapy
Treatment involves complete emptying of the uterus as soon as the diagnosis is made – even in cases where a spontaneous passage of the molar tissue appears to be complete. The reason is to avoid the development of an invasive mole (where the uterine wall is permeated by remaining tissue), and to limit the development of choriocarcinoma a very malignant tumor that invades the uterus and can spread rapidly via the blood system to bone, lungs, brain and other sites. Fortunately this cancer does respond well to hysterectomy, removal of ovaries plus aggressive chemotherapy.
In the vast majority of properly managed cases however, outcome after treatment is usually excellent. In cases where the beta hCG level fails to drop appropriately following evacuation of the uterus, chemotherapy will usually be curative. Close follow-up with serial quantitative blood hCG testing, ultrasound and/or Magnetic Resonance Imaging (MRI) is essential. After successful treatment, the woman must use very effective contraception for at least 6 to 12 months, so as to avoid pregnancy in order to allow for proper follow-up.

KIR & HLA-C mismatch
Name: Mel M
Hi Dr Sher,
I’m at a crossroads and desperate for advice. I’m 34 and my husband and I did 3 rounds of IVF to bank 4 euploid embryos. While I have low amh/DOR — my euploid rate was 80%. I also have stage 3 endometriosis that was excised in November. I fell pregnant 2 weeks after that surgery but unfortunately I’m suffering my second unassisted pregnancy loss in 9 months at the same gestation (5w5d). I wanted to check all immunology boxes before an embryo transfer. I just received my results. Unfortunately I am KIR AA and my husband is HLA-C c2/c2. My test did not show my HLA-C genotype but I can assume this is least favorable. We also have a HLA-DQa partial match. I feel I’m standing at the bottom of a mountain. I desperately want to carry but I don’t want to lose any embryos. I can’t afford to. Is surrogacy my best route? Is there any chance?

WE should talk: I suggest you call my assistant, Patti at 702-533-2691 and set up an online consultation with me.
When it comes to reproduction, humans face challenges compared to other mammals. A significant number of fertilized eggs in humans do not result in live births, with up to 75% failing to develop, and around 30% of pregnancies ending within the first 10 weeks (first trimester). Recurrent pregnancy loss (RPL) refers to two or more consecutive failed pregnancies, which is relatively rare, affecting less than 5% of women for two losses and only 1% for three or more losses. Understanding the causes of pregnancy loss and finding solutions is crucial for those affected. This article aims to explain the different types of pregnancy loss and shed light on potential causes.
Types of Pregnancy Loss: Pregnancy loss can occur at various stages, leading to different classifications:
- Early Pregnancy Loss: Also known as a miscarriage, this typically happens in the first trimester. Early pregnancy losses are usually sporadic, not recurring. In over 70% of cases, these losses are due to chromosomal abnormalities in the embryo, where there are more or fewer than the normal 46 chromosomes. Therefore, they are not likely to be repetitive.
- Late Pregnancy Loss: Late pregnancy losses occur after the first trimester (12th week) and are less common (1% of pregnancies). They often result from anatomical abnormalities in the uterus or cervix. Weakness in the cervix, known as cervical incompetence, is a frequent cause. Other factors include developmental abnormalities of the uterus, uterine fibroid tumors, intrauterine growth retardation, placental abruption, premature rupture of membranes, and premature labor.
Causes of Recurrent Pregnancy Loss (RPL): Recurrent pregnancy loss refers to multiple consecutive miscarriages. While chromosomal abnormalities are a leading cause of sporadic early pregnancy losses, RPL cases are mostly attributed to non-chromosomal factors. Some possible causes include:
- Uterine Environment Problems: Issues with the uterine environment can prevent a normal embryo from properly implanting and developing. These problems may include inadequate thickening of the uterine lining, irregularities in the uterine cavity (such as polyps, fibroid tumors, scarring, or adenomyosis), hormonal imbalances (progesterone deficiency or luteal phase defects), and deficient blood flow to the uterine lining.
- Immunologic Implantation Dysfunction (IID): IID is a significant cause of RPL, contributing to 75% of cases where chromosomally normal embryos fail to implant. It involves the immune system’s response to pregnancy, which can interfere with successful implantation.
- Blood Clotting Disorders: Thrombophilia, a hereditary clotting disorder, can disrupt the blood supply to the developing fetus, leading to pregnancy loss.
- Genetic and Structural Abnormalities: Genetic abnormalities are rare causes of RPL, while structural chromosomal abnormalities occur infrequently (1%). Unbalanced translocation, where part of one chromosome detaches and fuses with another, can lead to pregnancy loss. Studies also suggest that damaged sperm DNA can negatively impact fetal development and result in miscarriage.
IMMUNOLOGIC IMPLANTATION DYSFUNCTION AND RPL:
Autoimmune IID: Here an immunologic reaction is produced by the individual to his/her body’s own cellular components. The most common antibodies that form in such situations are APA and antithyroid antibodies (ATA). But it is only when specialized immune cells in the uterine lining, known as cytotoxic lymphocytes (CTL) and natural killer (NK) cells, become activated and start to release an excessive/disproportionate amount of TH-1 cytokines that attack the root system of the embryo, that implantation potential is jeopardized. Diagnosis of such activation requires highly specialized blood test for cytokine activity that can only be performed by a handful of reproductive immunology reference laboratories in the United States. Alloimmune IID, (i.e., where antibodies are formed against antigens derived from another member of the same species), is believed to be a common immunologic cause of recurrent pregnancy loss. Autoimmune IID is often genetically transmitted. Thus, it should not be surprising to learn that it is more likely to exist in women who have a family (or personal) history of primary autoimmune diseases such as lupus erythematosus (LE), scleroderma or autoimmune hypothyroidism (Hashimoto’s disease), autoimmune hyperthyroidism (Grave’s disease), rheumatoid arthritis, etc. Reactionary (secondary) autoimmunity can occur in conjunction with any medical condition associated with widespread tissue damage. One such gynecologic condition is endometriosis. Since autoimmune IID is usually associated with activated NK and T-cells from the outset, it usually results in such very early destruction of the embryo’s root system that the patient does not even recognize that she is pregnant. Accordingly, the condition usually presents as “unexplained infertility” or “unexplained IVF failure” rather than as a miscarriage. Alloimmune IID, on the other hand, usually starts off presenting as unexplained miscarriages (often manifesting as RPL). Over time as NK/T cell activation builds and eventually becomes permanently established the patient often goes from RPL to “infertility” due to failed implantation. RPL is more commonly the consequence of alloimmune rather than autoimmune implantation dysfunction. However, regardless, of whether miscarriage is due to autoimmune or alloimmune implantation dysfunction the final blow to the pregnancy is the result of activated natural killer cells (NKa) and cytotoxic lymphocytes (CTL B) in the uterine lining that damage the developing embryo’s “root system” (trophoblast) so that it can no longer sustain the growing conceptus. This having been said, it is important to note that autoimmune IID is readily amenable to reversal through timely, appropriately administered, selective immunotherapy, and alloimmune IID is not. It is much more difficult to treat successfully, even with the use of immunotherapy. In fact, in some cases the only solution will be to revert to selective immunotherapy plus using donor sperm (provided there is no “match” between the donor’s DQa profile and that of the female recipient) or alternatively to resort to gestational surrogacy.
DIAGNOSING THE CAUSE OF RPL.
In the past, women who miscarried were not evaluated thoroughly until they had lost several pregnancies in a row. This was because sporadic miscarriages are most commonly the result of embryo numerical chromosomal irregularities (aneuploidy) and thus not treatable. However, a consecutive series of miscarriages points to a repetitive cause that is non-chromosomal and is potentially remediable. Since RPL is most commonly due to a uterine pathology or immunologic causes that are potentially treatable, it follows that early chromosomal evaluation of products of conception could point to a potentially treatable situation. Thus, I strongly recommend that such testing be done in most cases of miscarriage. Doing so will avoid a great deal of unnecessary heartache for many patients. Establishing the correct diagnosis is the first step toward determining effective treatment for couples with RPL. It results from a problem within the pregnancy itself or within the uterine environment where the pregnancy implants and grows. Diagnostic tests useful in identifying individuals at greater risk for a problem within the pregnancy itself include Karyotyping (chromosome analysis) both prospective parents Assessment of the karyotype of products of conception derived from previous miscarriage specimens Ultrasound examination of the uterine cavity after sterile water is injected or sonohysterogram, fluid ultrasound, etc.) Hysterosalpingogram (dye X-ray test) Hysteroscopic evaluation of the uterine cavity Full hormonal evaluation (estrogen, progesterone, adrenal steroid hormones, thyroid hormones, FSH/LH, etc.) Immunologic testing to include Antiphospholipid antibody (APA) panel Antinuclear antibody (ANA) panel Antithyroid antibody panel (i.e., antithyroglobulin and antimicrosomal antibodies) Reproductive immunophenotype Natural killer cell activity (NKa) assay (i.e., K562 target cell test) Alloimmune testing of both the male and female partners
TREATMENT OF RPL
- Treatment for Anatomic Abnormalities of the Uterus:
This involves restoration through removal of local lesions such as fibroids, scar tissue, and endometrial polyps or timely insertion of a cervical cerclage (a stitch placed around the neck of the weakened cervix) or the excision of a uterine septum when indicated. Treatment of Thin Uterine Lining: A thin uterine lining has been shown to correlate with compromised pregnancy outcome. Often this will be associated with reduced blood flow to the endometrium. Such decreased blood flow to the uterus can be improved through treatment with sildenafil and possibly aspirin. sildenafil (Viagra) Therapy. Viagra has been used successfully to increase uterine blood flow. However, to be effective it must be administered starting as soon as the period stops up until the day of ovulation and it must be administered vaginally (not orally). Viagra in the form of vaginal suppositories given in the dosage of 25 mg four times a day has been shown to increase uterine blood flow as well as thickness of the uterine lining. To date, we have seen significant improvement of the thickness of the uterine lining in about 70% of women treated. Successful pregnancy resulted in 42% of women who responded to the Viagra. It should be remembered that most of these women had previously experienced repeated IVF failures. Use of Aspirin: This is an anti-prostaglandin that improves blood flow to the endometrium. It is administered at a dosage of 81 mg orally, daily from the beginning of the cycle until ovulation.
Treating Immunologic Implantation Dysfunction with Selective Immunotherapy:
Modalities such as intralipid (IL), intravenous immunoglobulin-G (IVIG), heparinoids (Lovenox/Clexane), and corticosteroids (dexamethasone, prednisone, prednisolone) can be used in select cases depending on autoimmune or alloimmune dysfunction. The Use of IVF in the Treatment of RPL In the following circumstances, IVF is the preferred option: When in addition to a history of RPL, another standard indication for IVF (e.g., tubal factor, endometriosis, and male factor infertility) is superimposed and in cases where selective immunotherapy is needed to treat an immunologic implantation dysfunction. The reason for IVF being a preferred approach when immunotherapy is indicated is that in order to be effective, immunotherapy needs to be initiated well before spontaneous or induced ovulation. Given the fact that the anticipated birthrate per cycle of COS with or without IUI is at best about 15%, it follows that short of IVF, to have even a reasonable chance of a live birth, most women with immunologic causes of RPL would need to undergo immunotherapy repeatedly, over consecutive cycles. Conversely, with IVF, the chance of a successful outcome in a single cycle of treatment is several times greater and, because of the attenuated and concentrated time period required for treatment, IVF is far safer and thus represents a more practicable alternative Since embryo aneuploidy is a common cause of miscarriage, the use of preimplantation genetic screening/ testing (PGS/T), with tests such as next generation gene sequencing (NGS), can provide a valuable diagnostic and therapeutic advantage in cases of RPL. PGS/T requires IVF to provide access to embryos for testing. There are a few cases of intractable alloimmune dysfunction due to absolute DQ alpha gene matching ( where there is a complete genotyping match between the male and female partners) where Gestational Surrogacy or use of donor sperm could represent the only viable recourse, other than abandoning treatment altogether and/or resorting to adoption. Other non-immunologic factors such as an intractably thin uterine lining or severe uterine pathology might also warrant that last resort consideration be given to gestational surrogacy. Conclusion:
Understanding the causes of pregnancy loss is crucial for individuals experiencing recurrent miscarriages. While chromosomal abnormalities are a common cause of sporadic early pregnancy losses, other factors such as uterine environment problems, immunologic implantation dysfunction, blood clotting disorders, and genetic or structural abnormalities can contribute to recurrent losses. By identifying the underlying cause, healthcare professionals can provide appropriate interventions and support to improve the chances of a successful pregnancy. The good news is that if a couple with RPL is open to all of the diagnostic and treatment options referred to above, a live birthrate of 70%–80% is ultimately achievable.

Natural Ivf
Name: Helen C
Hello. 3 years ago I underwent a standard ivf. 13 follicles, 11 oocytes, 9 mature, 6 fertilized, 2 blasts, one very poor quality, one hatching AA resulting in my daughter. Now I am 39 years old, AMH 2,68 and I want to try a natural Ivf. What chances do I have with my natural follicle to make a 5-day blast? Thank you.
Author
Answer:
I would urge you not to do NC IVF. Consider the following options:
Mini-IVF is a procedure that involves ovarian stimulation with oral fertility drugs such as clomiphene or letrozole to promote the development of follicles, for egg extraction. This is on the pretext that Mini-IVF, involves the administration of oral low-dosage medication, cuts down on cost, reduces the need for intensive monitoring and is highly successful.
Natural-cycle (NC)- IVF is an extension of the same concept. It relies on the development of follicles during natural ovulatory cycles, sufficient to permit extraction of one (and sometimes more) eggs, while completely avoiding the need for any of fertility drugs,
EZ-IVF: Sher Fertility Solutions (SFS)-NY is proud to announce the introduction of EZ-IVF, a low-cost, low risk, and highly successful alternative to Mini/NC-IVF . EZ-IVF is well suited to women under 40Y of age who have adequate ovarian reserve (AMH=>1.5ng/ml or > 10pmol/L). The process involves the use of very low dosage gonadotropin stimulation (administered every other day), thereby virtually eliminating the risk of complications. The process also requires minimal monitoring. It does all this at virtually the same low cost as Mini-IVF while offering a much higher potential for success and a greater likelihood that there will be left-over embryos for cryopreservation with a view to later use.
With regard to the argument given that both Mini and NC-IVF will yield comparable success rates to “conventional IVF”, please consider the following:
- Use of fewer drugs translates into lower cost. This would be true, were it not for the fact that success rates with mini-IVF across the board are much lower than with conventional ovarian stimulation. More important is the fact that the cost of IVF should be expressed in terms of “the cost of having a baby” rather than “cost per cycle of treatment”. When this is taken into account the cost associated with mini-IVF will be significantly higher than conventional IVF. Then there is the additional emotional cost associated with a much higher IVF failure rate with mini-IVF.
- Absent or milder stimulation using oral agents such as clomiphene, letrozole reduces stress on the ovaries and overall risk associated with IVF. This argument, while perhaps having some merit when applied to mini-IVF conducted in younger women who usually have normal ovarian reserve, does not hold water when it comes to older women and those with diminished ovarian reserve (DOR).. Furthermore, there is good body of evidence to show that both clomiphene and letrozole increase the release of LH-by the pituitary gland which so increases ovarian testosterone as to potentially further compromise egg development and maturation. .
- Women with DOR will respond better to “milder stimulation” and egg quality will so be enhanced. This assertion is totally flawed. It is like saying that applying less force to a heavier object will increase the likelihood of moving it”. That is simply not how FSH stimulates follicle development.
- Mini-IVF is less technology driven, less stressful and easier to execute. There is some merit to this assertion although all IVF cycles require careful monitoring and the same involvement of the embryology laboratory.
There can be little doubt that aside from a woman’s age, the method used for ovarian stimulation represents the most important determinant of egg/embryo quality and thus of IVF outcome. There is no single stimulation protocol that is suitable for all IVF patients. It must be individualized…. especially when it comes to women who, regardless of their age have DOR and for women over >35y of age for whom the use of clomiphene for ovarian stimulation is not optimal.
So, what about younger women with normal or increased ovarian reserve? If mini-IVF has any role at all, it could be in such cases. I do not not advocate aggressively stimulating the ovaries of younger women who have normal or increased ovarian reserve (as assessed by basal FSH& AMH) simply to try and access more eggs. In fact, such an approach is neither safe nor acceptable. In such women it is often wiser to use lower dosage stimulation to try and prevent the development of severe ovarian hyperstimulation syndrome (OHSS) which aside from putting the woman at severe risk , can also compromise egg/embryo quality. This is where EZ-IVF comes in! For the reasons state above, it offers a rational alternative to “conventional” IVF as well las to Mini-IVF and NC-IVF.
I invite you to contact me at Sher Fertility Solutions (SFS) if you are interested in learning more about this exciting development, called EZ-IVF.

withdrawal bleeding during estrogen and progesteron supplementation a week after FET
Name: Maria K
Dear Dr.Sher. I am an ENT doctor from Europe. I am diagnosed with PCOS and I have amenorrhea and no ovulation at all. One year ago my fertility doctor prescribed me Letrozol, because I wanted to conceive. Not only that I didn’t have ovulation, but there was also a complete lack of estrogen and very very thin uterine lining. Due to this result we decided to do an IVF. The stimulation protocol was done, but we decided to do FET due to the high risk of ovarian hyperstimulation. We did the embryotransfer on the 20th day while I had estrogen and progesteron supplementation. Unfortunately my period came seven days after the transfer and I don’t know why. I performed a blood test and the values of estrogen and profesteron were normal. My fertility doctor cannot find an explanation either. We have another frozen embryos and we will try again, but since we don’t have an explanation I am afraid that menstruation could come again early.

Answer:
It could be an implantation dysfunction due to another thin endometrium (endometrial insufficiency,
Back in 1989, I conducted a study that examined how the thickness of a woman’s uterine lining, known as the endometrium, affected the successful implantation of embryos in IVF patients. The study revealed that when the uterine lining measured less than 8mm in thickness by the day of the “hCG trigger” in fresh IVF cycles, or at the start of progesterone therapy in embryo recipient cycles (such as frozen embryo transfers or egg donation IVF), the chances of pregnancy and birth were significantly improved. In my opinion, an ideal estrogen-promoted endometrial lining should measure at least 9mm in thickness, while a lining of 8-9mm is considered “intermediate.” In most cases, an estrogenic lining of less than 8mm is unlikely to result in a viable pregnancy.
A “poor” uterine lining typically occurs when the innermost layer of the endometrium, called the basal or germinal endometrium, fails to respond to estrogen and cannot develop a thick enough outer “functional” layer to support optimal embryo implantation and placenta development. The “functional” layer makes up two-thirds of the total endometrial thickness and is the layer that sheds during menstruation if no pregnancy occurs.
The main causes of a “poor” uterine lining include:
- Damage to the basal endometrium due to:
-
- Inflammation of the endometrium (endometritis) often resulting from retained products of conception after abortion, miscarriage, or birth.
- Surgical trauma caused by aggressive uterine scraping during procedures like D&C.
- Insensitivity of the basal endometrium to estrogen due to:
-
- Prolonged or excessive use of clomiphene citrate.
- Prenatal exposure to diethylstilbestrol (DES), a drug given to pregnant women in the 1960s to prevent miscarriage.
- Overexposure of the uterine lining to ovarian male hormones, mainly testosterone, which can occur in older women, women with diminished ovarian reserve, and women with polycystic ovarian syndrome (PCOS) who have increased LH biological activity. This hormonal imbalance leads to the overproduction of testosterone in the ovary’s connective tissue, further exacerbated by certain ovarian stimulation methods used in IVF.
- Reduced blood flow to the basal endometrium, often caused by:
-
- Multiple uterine fibroids, especially those located beneath the endometrium (submucosal).
- Uterine adenomyosis, an abnormal invasion of endometrial glands into the uterine muscle.
“The Viagra Connection”
Eighteen years ago, I reported on the successful use of vaginal Sildenafil (Viagra) in treating women with implantation dysfunction caused by thin endometrial linings. This breakthrough led to the birth of the world’s first “Viagra baby.” Since then, thousands of women with thin uterine linings have been treated with Viagra, and many have gone on to have babies after multiple unsuccessful IVF attempts.
Viagra gained popularity in the 1990s as an oral treatment for erectile dysfunction. Inspired by its mechanism of action, which increases penile blood flow through enhanced nitric oxide activity, I investigated whether vaginal administration of Viagra could improve uterine blood flow, deliver more estrogen to the basal endometrium, and promote endometrial thickening. Our findings confirmed that vaginal Viagra achieved these effects, while oral administration did not provide significant benefits. To facilitate treatment, we collaborated with a compound pharmacy to produce vaginal Viagra suppositories.
In our initial trial, four women with a history of poor endometrial development and failed conception underwent IVF treatment combined with vaginal Viagra therapy. The Viagra suppositories were administered four times daily for 8-11 days and stopped 5-7 days before embryo transfer. This treatment resulted in a rapid and significant improvement in uterine blood flow, leading to enhanced endometrial development in all four cases. Three of these women subsequently conceived. In 2002, I expanded the trial to include 105 women with repeated IVF failure due to persistently thin endometrial linings. About 70% of these women responded positively to Viagra therapy, with a notable increase in endometrial thickness. Forty-five percent achieved live births after a single cycle of IVF with Viagra treatment, and the miscarriage rate was only 9%. Women who did not show improvement in endometrial thickness following Viagra treatment did not achieve viable pregnancies.
When administered vaginally, Viagra is quickly absorbed and reaches the uterine blood system in high concentrations. It then dilutes as it enters the systemic circulation, explaining why treatment is virtually free from systemic side effects.
It is important to note that Viagra may not improve endometrial thickness in all cases. Approximately 30-40% of women treated may not experience any improvement. In severe cases of thin uterine linings where the basal endometrium has been permanently damaged and becomes unresponsive to estrogen, Viagra treatment is unlikely to be effective. This can occur due to conditions such as post-pregnancy endometritis, chronic inflammation resulting from uterine tuberculosis (rare in the United States), or extensive surgical damage to the basal endometrium.
In my practice, I sometimes recommend combining vaginal Viagra administration with oral Terbutaline (5mg). Viagra relaxes the muscle walls of uterine spiral arteries, while terbutaline relaxes the uterine muscle itself. The combination of these medications synergistically enhances blood flow through the uterus, improving estrogen delivery to the endometrial lining. However, it’s important to monitor potential side effects of Terbutaline such as agitation, tremors, and palpitations. Women with cardiac disease or irregular heartbeat should not use Terbutaline.
Approximately 75% of women with thin uterine linings respond positively to treatment within 2-3 days. Those who do not respond well often have severe inner ( (basal) endometrial lining damage, where improved uterine blood flow cannot stimulate a positive response. Such cases are commonly associated with previous pregnancy-related endometrial inflammation, occurring after abortions, infected vaginal deliveries, or cesarean sections.
Viagra therapy has been a game-changer for thousands of women with thin uterine linings, allowing them to successfully overcome infertility and build their families.
