Cyclofenil, sold under the brand name Sexovid among others, is a selective estrogen receptor modulator (SERM) medication which is used as a gonadotropin stimulant or ovulation inducer and in menopausal hormone therapy in women.[3][4][5][6] It is mostly no longer available.[6] The medication is taken by mouth.[7][8][9]

Side effects of cyclofenil include liver toxicity among others.[10] It is a selective estrogen receptor modulator (SERM) and hence is a mixed agonist–antagonist of the estrogen receptor (ER), the biological target of estrogens like estradiol.[8] It has antiestrogenic effects on the hypothalamic–pituitary–gonadal axis and hence can increase sex hormone production and stimulate ovulation.[8][11]

Cyclofenil was introduced for medical use in 1970.[12] It has been mostly discontinued, but remains available in a few countries, including Brazil, Italy, and Japan.[6][13][3] It has been used as a doping agent by male athletes.[8]
