I've been told by one of my clients that her doctor has warned her off the consumption of whey because it has negative effects on fertility as she's trying to get pregnant.
I've had a look on pubmed and google, but the only reference I can find to whey and infertility is a line saying "Whey has been shown to have testosterone-like effects on lab rats, so maybe that's the cause of the ovulation disorders"
Testosterone-LIKE effects? Rats? Does anybody have any more (hopefully clear cut) information on this topic? My client won't eat meat except fish and I'm struggling to find an additional protein source for her.
