I recommend doing a search on this board for more information. When males are taking feminizing herbs for NBE, I think it's logical to assume such individuals become more susceptible to developing a estrogen/progesterone imbalance. I use progesterone cream to help prevent a hormonal imbalance that could otherwise be created by the pm I'm taking.

Further, it's not just males pursuing NBE that can experience this imbalance:

Although estrogen dominance in men is most commonly caused by factors such as obesity, alcoholism, or exposure to a form of environmental estrogen called xenoestrogens, it can be caused by a number of serious medical problems, including pituitary diseases and testicular tumors. If you suspect you may have estrogen dominance, consult your doctor immediately.
