FET lining 17

Hi, I read a lot online about the lining being too thick for a successful FET. Mine is measuring 17 and still a week to go. Should I be concerned or are they right were good to move forward with… — Jennifer M.

Endo and Lupron

Hello, I scored 1.8 on the Receptiva test, and had a laparoscopy two weeks ago that revealed pelvic and bowel adhesions, and a blocked tube (all likely caused by a past silent infection - not from endo?). They also found… — Mel P.

Dr. Geoffrey Sher answered

I personally do not advocate long acting Lupron for treating endometriosis-related infertility. When women with infertility due to endometriosis seek treatment, they are all too often advised to first try ovarian stimulation (ovulation Induction) with intrauterine insemination (IUI) ………as if to say that this would be just as…

Follicle and lining

Hi Dr.sher, As a follow up to my last question. Could you still do an FET if the lining thickens to a good size although the follicle is slow to develop/lack of ovulation. My lining is close to 7 mm… — Kristin C.

Dr. Geoffrey Sher answered

In my opinion, the lining needs to be >8mm (at least) prior to ovulation and/or progesterone supplementation. Geoff Sher

Is there an optimal timing of the trigger/embryo transfer on a modified natural cycle

I went in for a scan today in anticipation of doing a modified natural cycle, it's day 10 - LH levels are rising -I've not reached ovulation yet, LH normally surges on day 14 for me. The lining was trilaminar… — Cassidy O.

Dr. Geoffrey Sher answered

Candidly, I am not a fan of modified natural cycle FET's. However, the time to trigger is just before the onset of the natural LH surge.; This is determined by the size (20+mm) of the dominaqnt follicle and bloopd E2. (150pg/ml+ or 300+ if there are >2 dominant…

Second hand infertility

Hi, I came across your podcast about implantation issues. I went thru infertility issues for 4 years (Ivf wasn’t covered) 19iuis- I had a miscarriage in the 2nd trimester- 3 chemical pregnancies and 2 miscarriages ending before 9 weeks we… — Lauren B.

Dr. Geoffrey Sher answered

Clearly you have recurrent pregnancy loss...likely due to an implantation dysfunction (anatomical or immunologic.However, I would need much more information to be able to comment authoritatively. When it comes to reproduction, humans face challenges compared to other mammals. A significant number of fertilized eggs in humans do not…

PGTA/Endometriosis

Hi, quick background info- 37 years old, husband is 48 years old. I have stage 4 endometriosis with bilateral endometriomas about 4-5 cm on both ovaries. AMH of 3.8, FSH 5.5, Estradiol 45. Sperm analysis is above normal. I just… — Marie F.

Dr. Geoffrey Sher answered

When women with infertility due to endometriosis seek treatment, they are all too often advised to first try ovarian stimulation (ovulation Induction) with intrauterine insemination (IUI) ………as if to say that this would be just as likely to result in a baby as would in vitro fertilization (IVF).…

Do you think my problem is immunological?

Dear Dr Sher, I have a history of 5 natural pregnancies complicated by pre-eclampsia, 2 previous csection births. After my last birth via csection, i have had 3 first trimester miscarriages. I'm now undergoing ivf with donor eggs due to… — Lisa W.

Dr. Geoffrey Sher answered

It is indeed possible that you have acquired an immunologic implantation dysfunction. In the world of assisted reproduction, when IVF fails repeatedly or without explanation, it's often assumed that poor embryo quality is the main culprit. However, this view oversimplifies the situation. The process of embryo implantation, which…

Cyst at baseline

Hello Dr, At my baseline scan there was a cyst measured 11mm, i.e. borderline acceptable. Nurses took my blood to check oestradiol level in case Doctor wanted to check it - but the Doctor reported back and said blood test… — Cassidy O.

Dr. Geoffrey Sher answered

Especially since you are doing an FET and there has been no impact on your cycle thus far, I would tend to agree with your RE that the 10mm follicle/cyst is probably irrelevant! Good Luck! Geoff Sher ADDITIONAL INFORMATION: I am attaching online links to two E-books which…

Fertility options

My wife was diagnoses last year with Adenomyosis after having a miscarriage, and had a DNC. We've been having trouble getting pregnant ever since, and would like to know all options. We saw this on a show, and wondering if… — Adam L.

Dr. Geoffrey Sher answered

Adenomyosis is a condition where endometrial glands develop outside the uterine lining (endometrium), within the muscular wall of the uterus (myometrium). Definitive diagnosis of adenomyosis is difficult to make. The condition should be suspected when a premenopausal woman (usually>25 years of age) presents with pelvic pain, heavy painful…

IVF FET PREP

I am doing my first FET prep cycle - I am on oral estrogen (2mg) and estrogen patches (0.1mg/day) I started at 2 patches and 1 pill per day and then gradually bumped up to 3 pills and 3 patches… — Mikie D.

Dr. Geoffrey Sher answered

There are different approaches to hormonal preparation of the uterine lining for FET. In my practice, the following is the approach I take.. I think using this might prevent the kind of response you experienced last time. Until less than 3 decades ago, most women undergoing IVF would…

Dr. Geoffrey Sher answered

Implantation dysfunction is unfortunately often overlooked as an important cause of IVF failure. In the pursuit of optimizing outcome with IVF, the clinician has a profound responsibility to meticulously assess and address this important issue if IVF success is to be optimized. This is especially relevant in cases…

Do You Offer Reproductive Immunology As A Separate Specialty/Service?

Hello Dr. Sher, I am a patient working with an IVF Clinic that holds 2 more of my PGT-A Euploid Embryos (using Donor Eggs and my husband's sperm), but we have unfortunately arrived at a crossroads where my smaller clinic… — Deanna T.

Dr. Geoffrey Sher answered

Ethanol Sclerotherapy?

Hi, I have what appears to be a 7cm endometrioma on my left ovary. I had surgery to remove an ovarian cyst on the same ovary a year ago and it regrew to the same size within 4 months. An… — Sarah K.

Dr. Geoffrey Sher answered

I introduced ovarian sclerotherapy using 5% tetracycline hydrochloride (THCL). Unfortunately we cannot access THCL any longer. Therefore, surgery is advised in your case. Personally, it is rarely necessary to remove the entire ovary. In my opinion, the cyst should be isolated and removed leaving most of the ovary…

High progesterone

Hi Dr., On the day of my last fresh transfer my progesterone level was 350nmol/l (far too high) & I still wonder if it contributed to my failed cycle. Five days later I produced/was leaking breast milk & had symptoms… — Rosie S.

Dr. Geoffrey Sher answered

Respectfully, I do not believe your sad loss had anything to do with the high progesterone.
