Tom - A woman is asking about the breastfeeding compatibility of two fertility drugs that she is planning on using in the fall when her baby will be about 18 months old. They are "companion drugs called Fertinex and Profasi." In a 1996 post you said Profasi was simply injectable human chorionic gonadotropin, which is produced in large quantities during pregnancy and is not a problem. What about Fertinex?
