Progestins, including progesterone, are vital for preparing the uterus for the implantation of a fertilized egg during the luteal phase of the menstrual cycle. If fertilization, implantation, and other events necessary for pregnancy occur, increased progestin (i.e., progesterone) levels are essential in maintaining the pregnancy.
Puberty blockers (also called puberty inhibitors or hormone blockers) are medicines used to postpone puberty in children. The most commonly used puberty blockers are gonadotropin-releasing hormone (GnRH) agonists, which suppress the natural production of sex hormones, such as androgens (e.g. testosterone) and estrogens (e.g. estradiol).
[8] [9] In men, they are being investigated in the treatment of benign prostatic hyperplasia [10] and also as potential contraceptive agents. [11] GnRH antagonists could be used as puberty blockers in transgender youth and to suppress sex hormone levels in transgender adolescents and adults. [12] [13] [14] [15]
Cyproterone acetate (CPA), sold alone under the brand name Androcur or with ethinylestradiol under the brand names Diane or Diane-35 among others, is an antiandrogen and progestin medication used in the treatment of androgen-dependent conditions such as acne, excessive body hair growth, early puberty, and prostate cancer, as a component of feminizing hormone therapy for transgender individuals ...

Progestogens share the common feature of being able to bind to the body's progesterone receptors and enact a physiological effect similar to naturally occurring progesterone. [11] Still, there are differences between progestogens, and various organizational systems exist to categorize the progestogen hormones used in oral contraception medications.
It may be used for precocious puberty in both males and females, [14] and to prevent premature ovulation in cycles of controlled ovarian stimulation for in vitro fertilization . This use is controversial since the Lupron label advises against using the drug when one is considering pregnancy, due to a risk of birth defects.
The main biological role of progestogens in the body is in the female reproductive system, and the male reproductive system, [19] with involvement in regulation of the menstrual cycle, maintenance of pregnancy, and preparation of the mammary glands for lactation and breastfeeding following parturition in women; in men progesterone affects ...
