User:Mr. Ibrahem/Progestogen-only pill

Progestin-only pills (POP), also known as minipills, are birth control pills that contain progestogen (progestin) and not estrogen. With typical use about 9% become pregnant in the first year, while with perfect use it is 0.3%. Other uses include painful periods, endometriosis, and sickle cell disease. Fertility returns immediately after stopping use.

Side effects are few, with no increased risk of blood clots or breast cancer. Though, they may result in irregular vaginal bleeding. Effectiveness requires use at the same time each day. They do not protect against sexually transmitted infections (STIs). They may be used during breastfeeding. They primarily work by stopping the release of eggs.

Progestin-only pills came into medical use in 1968 in France. There are currently a number of progestin-only formulations. One, norgestrel, was approved for over the counter sale in 2023, in the United States. No testing is required before starting. In the United States they cost between 25 USD and 200 USD per month as of 2023.
