In this episode, I'm joined by Dr. Geoffrey Sher of Sher Fertility Solutions. He is an internationally renowned fertility expert. He trained under “The Fathers of IVF, ” Drs. Patrick Steptoe and Robert Edwards in the UK. In 1982 he established the 1st private (non-university based) IVF program in the US. Over a career spanning almost 40 years Dr. Sher has been influential in the births of over 17000 IVF babies and has helped fashion the entire field of ART. He is the author of “ In Vitro Fertilization, the A.R.T. of Making Babies” and (more recently), “Unexplained IVF failure and Recurrent pregnancy loss: The Immunologic Link”." Today he's joining me to talk about Immunologic Implantation Dysfunction (IID), which may be a factor in unexplained IVF failure and recurrent pregnancy loss (RPL). He will be talking about how the endometrial lining plays an important role in embryo implantation, because as he shares, "you can't put a good seed in bad soil, or a bad seed in good soil."
