Progestogen-only injectable contraceptive

Progestogen-only injectable contraceptives (POICs) are a form of hormonal contraception and progestogen-only contraception that are administered by injection and providing long-lasting birth control.[2][3] As opposed to combined injectable contraceptives, they contain only a progestogen without an estrogen, and include two progestin preparations:[2][3]

Research

Progestogens that have been studied for potential use as POICs but were never marketed as such include the progesterone derivatives algestone acetophenide (dihydroxyprogesterone acetophenide) (100 mg/month), chlormadinone acetate (250 mg/3 months), hydroxyprogesterone caproate (250–500 mg/month), gestonorone caproate (2.5–200 mg/1–2 months), and oxogestone phenpropionate (50–75 mg/month), and the testosterone derivatives lynestrenol phenylpropionate (25–75 mg/month), levonorgestrel butanoate, levonorgestrel cyclobutylcarboxylate, and levonorgestrel cyclopropylcarboxylate.[6][7] Some of these have been introduced for use in combined injectable contraceptives instead.[6][8][9]
