We are approaching a time that freezing eggs will be a standard option for an IVF program much like Embryo freezing is today.  Despite the fact that hundreds of babies have been born apparently without an increase in defects or abnormalities, the American Society for Reproductive Medicine (ASRM) has proclaimed that Egg freezing is still considered experimental.

As a result, patients going through minimal stimulation …

Sometimes my patients who have difficulty conceiving their second child feel like second class citizens in the infertility world.  Unlike their infertile peers without a child they perceive that friends, family and even their doctor’s offices do not have the same sympathy and concern for them as they observe others without a child receive.  I have had patients express guilt …

Infertility and The Overweight Woman

David Kreiner, MD Obesity, PCOS 15 Comments

The most shocking thing I’ve experienced in my 30 year career in Reproductive Endocrinology has been the consistent “resistance” among specialists to treat women with obesity. This “resistance” has felt at times to both me and many patients to be more like a prejudice. I have heard other REI specialists say that it is harder for women to conceive until …
