Hi, D.,
I went through almost every form of fertility treatment to produce my first live child. None of my physicians, including obstetricians, perinatologists (high-risk obstetricians), reproductive endocrinologists, and reproductive immunologists recommended using egg whites. I'm also a health (including fertility) researcher, so I read a lot of medical journals. I have not come across what I consider compelling evidence for its use in significantly increasing the odds of conception. There are many stories of women becoming pregnant right after using egg white, but there is no way of knowing whether they became pregnant for a thousand other reasons. I suspect the thousand other reasons brought about these conceptions, to be honest. However, if you come across compelling, scientifically-substantiated evidence that supports the use of egg whites for this purpose, please let me know!
Best wishes,
Lynne
