Thin uterine lining after egg retrieval

Is it possible to have damaged the lining of my uterus during egg retrieval? My uterine lining went from 9.9mm 2 days before egg retrieval to 5mm after. Please advise. — Shernelle T.

Dr. Geoffrey Sher answered

That is highly unusual. The ER would not have caused this. Perhaps one of these measurements was not accurate. It was as far back as 1989, when I first published a study that examined the correlation between the thickness of a woman’s uterine lining (the endometrium), and the…

3 miscarriages

Dr. Geoffrey Sher answered

When it comes to reproduction, humans are the poorest performers of all mammals. In fact we are so inefficient that up to 75% of fertilized eggs do not produce live births, and up to 30% of pregnancies end up being lost within 10 weeks of conception (in the…

PGT embryos no implantation

Hi, Why would I get pregnant naturally twice (ended in 6 week miscarriages) within 6 months, but have had 2 good quality pgt embryos fail to implant? Why would it implant naturally and not with IVF? Thanks — Laura P.

Dr. Geoffrey Sher answered

This sounds like implantation dysfunction. Implantation dysfunction is unfortunately often overlooked as an important cause of IVF failure. This is especially relevant in cases of unexplained IVF failure, recurrent pregnancy loss (RPL), and in women with underlying endo-uterine surface lesions, thickness of the uterine lining (endometrium) and /or…

Trigger using HCG10,000 and Decapeptyl

IVF pregnancy age limit?

Dear Dr. Sher, I’d like to know if you have an age limit for assisting a post-menopausal woman to get pregnant with IVF? 50, 55, 60, 65 .. ? Thank you, ~Beth — Beth R.

Dr. Geoffrey Sher answered

Our cut off using own eggs is 47y. In my opinion doing IVF with own eggs over 43y is not wise. However, there is no definitive cut-off when donor eggs are used. I believe this very much depends on the health of the individual patient. Geoff Sher ADDITIONAL…
