There clearly is both male factor infertility and diminished ovarian reserve (DOR). Both issues need to be thoroughly evaluated and addressed. The cause of the male factor will need further testing and the DOR requires a very individualized approach to ovarian stimulation…(see below).
I strongly suggest that you contact my assistant, Patti Converse (702-533-2691) and set up an online consultation with me to discuss,
- ADDRESSING DIMINISHING OVARIAN RESERVE (DOR) IN IVF
Understanding the impact of ovarian reserve on the success of in vitro fertilization (IVF) is crucial when it comes to reproductive health. This article aims to simplify and clarify these concepts, emphasizing their significance in the selection of ovarian stimulation protocols for IVF. By providing you with this information, we hope to shed light on the importance of considering these factors and making informed decisions regarding fertility treatments.
- The Role of Eggs in Chromosomal Integrity: In the process of creating a healthy embryo, it is primarily the egg that determines the chromosomal integrity, which is crucial for the embryo’s competency. A competent egg possesses a normal karyotype, increasing the chances of developing into a healthy baby. It’s important to note that not all eggs are competent, and the incidence of irregular chromosome numbers (aneuploidy) increases with age.
- Meiosis and Fertilization: Following the initiation of the LH surge or the hCG trigger shot, the egg undergoes a process called meiosis, halving its chromosomes to 23. During this process, a structure called the polar body is expelled from the egg, while the remaining chromosomes are retained. The mature sperm, also undergoing meiosis, contributes 23 chromosomes. Fertilization occurs when these chromosomes combine, resulting in a euploid embryo with 46 chromosomes. Only euploid embryos are competent and capable of developing into healthy babies.
- The Significance of Embryo Ploidy: Embryo ploidy, referring to the numerical chromosomal integrity, is a critical factor in determining embryo competency. Aneuploid embryos, which have an irregular number of chromosomes, are often incompetent and unable to propagate healthy pregnancies. Failed nidation, miscarriages, and chromosomal birth defects can be linked to embryo ploidy issues. Both egg and sperm aneuploidy can contribute, but egg aneuploidy is usually the primary cause.
- Embryo Development and Competency: Embryos that develop too slowly or too quickly, have abnormal cell counts, contain debris or fragments, or fail to reach the blastocyst stage are often aneuploid and incompetent. Monitoring these developmental aspects can provide valuable insights into embryo competency.
- Diminished Ovarian Reserve (DOR): As women advance in their reproductive age, the number of remaining eggs in the ovaries decreases. Diminished ovarian reserve (DOR) occurs when the egg count falls below a certain threshold, making it more challenging to respond to fertility drugs effectively. This condition is often indicated by specific hormone levels, such as elevated FSH and decreased AMH. DOR can affect women over 40, but it can also occur in younger
Why IVF should be regarded as treatment of choice for women who have diminished ovarian reserve ( DOR):
Understanding the following factors will go a long way in helping you to make an informed decision and thereby improve the chances of a successful IVF outcome.
- Ovarian Reserve: While chronological age plays a vital role in determining the quality of eggs and embryos [there is an increased risk of egg aneuploidy (irregular chromosome number) in eggs, leading to reduced embryo competency. Additionally, women with declining ovarian reserve (DOR), regardless of their age, are more likely to have aneuploid eggs/embryos. Therefore, it is crucial to address age-related factors and ovarian reserve to enhance IVF success.
- Excessive Luteinizing Hormone (LH) and Testosterone Effects: In women with DOR, their ovaries and developing eggs are susceptible to the adverse effects of excessive LH, which stimulates the overproduction of male hormones like testosterone. While some testosterone promotes healthy follicle growth and egg development, an excess of testosterone has a negative impact. Therefore, in both older women or those who (regardless of their age) have DOR, ovarian stimulation protocols that down-regulate LH activity before starting gonadotropins are necessary to improve egg/embryo quality and IVF outcomes.
- It is possible to regulate the decline in egg/embryo competency by tailoring ovarian stimulation protocols. Here are my preferred protocols for women with relatively normal ovarian reserve:
- Conventional Long Pituitary Down Regulation Protocol:
- Begin birth control pills (BCP) early in the cycle for at least 10 days.
- Three days before stopping BCP, overlap with an agonist like Lupron for three days.
- Continue daily Lupron until menstruation begins.
- Conduct ultrasound and blood estradiol measurements to assess ovarian status.
- Administer FSH-dominant gonadotropin along with Menopur for stimulation.
- Monitor follicle development through ultrasound and blood estradiol measurements.
- Trigger egg maturation using hCG injection, followed by egg retrieval.
- Agonist/Antagonist Conversion Protocol (A/ACP):
- Similar to the conventional long down regulation protocol but replace the agonist with a GnRH antagonist from the onset of post-BCP menstruation until the trigger day.
- Consider adding supplementary human growth hormone (HGH) for women with DOR.
- Consider using “priming” with estrogen prior to gonadotropin administration
- Protocols to Avoid in Women with DOR: Certain ovarian stimulation protocols may not be suitable for women with declining ovarian reserve:
- Microdose agonist “flare” protocols
- High dosages of LH-containing fertility drugs such as Menopur
- Testosterone-based supplementation
- DHEA supplementation
- Clomiphene citrate or Letrozole
- Low-dosage hCG triggering or agonist triggering for women with DOR
Preimplantation Genetic Screening/Testing for aneuploidy (PGS/PGTA): PGS/PGTA is a valuable tool for identifying chromosomal abnormalities in eggs and embryos. By selecting the most competent (euploid) embryos, PGS/PGTA significantly improves the success of IVF, in women with DOR.
Understanding the impact of declining ovarian reserve on IVF outcomes is essential when making decisions about fertility treatments. Diminished ovarian reserve (DOR) can affect egg quality and increase the likelihood of aneuploid embryos with resultant IVF failure. By considering this factor, you can make informed choices and work closely with fertility specialists to optimize your chances of success. Remember, knowledge is power, and being aware of these aspects empowers you to take control of your reproductive journey.
