I'll give you the response that has always been given historically: If you are at all concerned about fertility, either bank some sperm or don't pursue NBE. The herbs involved can cause sterility, impotence, and loss of libido. They may not do it to everyone, but you probably don't want to take any chances. So, I guess the answer is that growing breasts and being fertile are mutually exclusive for genetic males. Pick one or the other.
