The hormone responsible mostly for development of nipple tissue, and is also strongly tied to the menstrual cycle. It's believed that this hormone is responsible for PMS. Usually it's only taken by MTF transsexuals on hormone replacement therapy who want that little extra oomph on their tits and don't mind getting extra-bitchy once a month.

This is also what's in birth control pills.

progestin: a synthetic type of progesterone. Synonym, gestagen; progestogen; any one of the class of synthetic sex-hormonal steroids that has a physiologic action resembling progesterone; also known as gestagen.
