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.
Side effects of progestogens include menstrual irregularities, headaches, nausea, breast tenderness, mood changes, acne, increased hair growth, and changes in liver protein production among others. [1] [2] Other side effects of progestogens may include an increased risk of breast cancer, cardiovascular disease, and blood clots. [2]
Progestogen-only pills," "Progestin-only pills," and "Progesterone-only pills" are terms each referring to the same class of synthetic hormone medications. The phrase "Progestogen-only pill" is used by the World Health Organization and much of the international medical community. [ 7 ]
In accordance, different publications have stated based on preclinical experiments that a 2- to 5-fold excess of CPA can inhibit the effects of testosterone by 50%, a 3- to 10-fold excess of CPA can reduce the effects of "potent androgens" (presumably testosterone and/or DHT) by 50%, and a 10-fold excess of CPA can inhibit the effects of ...
Progesterone, via transformation into neurosteroids such as 5α-dihydroprogesterone, 5β-dihydroprogesterone, allopregnanolone, and pregnanolone (catalyzed by the enzymes 5α-and 5β-reductase and 3α- and 3β-HSD), is a positive allosteric modulator of the GABA A receptor, and is associated with a variety of effects mediated by this property ...
Side effects of etonogestrel include menstrual irregularities, breast tenderness, mood changes, acne, headaches, vaginitis, and others. [4] Etonogestrel is a progestin , or a synthetic progestogen , and hence is an agonist of the progesterone receptor , the biological target of progestogens like progesterone . [ 16 ]

The incidence of certain side effects is different for the different formulations: for example, breakthrough bleeding is much more common with progestogen-only methods. Certain serious complications occasionally caused by estrogen-containing contraceptives are not believed to be caused by progestogen-only formulations: deep vein thrombosis is ...
