Progestogens mediate their contraceptive effects by multiple mechanisms, including prevention of ovulation via their antigonadotropic effects; thickening of cervical mucus, making the cervix largely impenetrable to sperm; preventing capacitation of sperm due to changes in cervical fluid, thereby making sperm unable to penetrate the ovum; and ...
Adenomyosis is a medical condition characterized by the growth of cells that proliferate on the inside of the uterus (endometrium) atypically located among the cells of the uterine wall , [2] as a result, thickening of the uterus occurs. As well as being misplaced in patients with this condition, endometrial tissue is completely functional.
Alteration of the endometrial lining of the uterus through modification of the structure of endometrial glands and their corresponding secretary patterns, as well as causing the endometrial lining to thin out . Overall, the endometrium becomes less suitable for implantation of a fertilized egg and the likelihood of a viable pregnancy decreases.
The most common adverse effects include abdominal pain, feeling tired, and vaginal bleeding. [8] Serious side effects may include heavy vaginal bleeding, bacterial infection, and, if pregnant, birth defects. [8] When used, appropriate follow-up care needs to be available. [8] [14] Mifepristone is primarily an antiprogestogen. [8]
Different sources note different incidence of side effects. The most common side effect is breakthrough bleeding. Combined oral contraceptive pills can improve conditions such as dysmenorrhea, premenstrual syndrome, and acne, [105] reduce symptoms of endometriosis and polycystic ovary syndrome, and decrease the risk of anemia.

These effects can be minimized if treated with progestin, but not in very many cases. Estrogen and progesterone have an antagonistic relationship. Estrogen promotes the growing of endometrial lining, while progesterone limits it. [67] In the case of endometrial cancer, progesterone can negatively regulate estrogen driven growth.
Dr. Laura Purdy, chief medical officer at Wisp, a sexual health care group, says that “uterus didelphys is rare,” only accounting for 8% of the congenital anomalies of the female reproductive ...
The side effects of cyproterone acetate (CPA), a steroidal antiandrogen and progestin, including its frequent and rare side effects, have been studied and characterized.It is generally well-tolerated and has a mild side-effect profile, regardless of dosage, when it used as a progestin or antiandrogen in combination with an estrogen such as ethinylestradiol or estradiol valerate in women.
