Benzestrol (originally called 118B and Octofollin), synthetic nonsteroidal estrogen and analog of stilbestrol, was used for oral estrogenic therapy for women and in order to prevent premature births. Besides, benzestrol gave most of the patients’ satisfactory relief of their estrogen deficiency symptoms. However, its use has been discontinued.
