Cyclofenil

Cyclofenil (INN, trade names Ondogyne, Sexovid, and others) is a selective estrogen receptor modulator.

Cyclofenil was investigated in the 1970s as a agent to induce ovulation in infertile women. It was then investigated as a possible treatment for scleroderma in the 1980s, but was found to be ineffective. Later study of its efficacy in treating Raynaud's phenomenon in people with scleroderma also found no statistically significant benefit.
