Dienestrol (INN, USAN) (brand names Dienoestrol, Denestrolin, Dienol and many others [lower-alpha 1] ), also known as dienoestrol (BAN), is a synthetic nonsteroidal estrogen medication of the stilbestrol group which is or was used to treat menopausal symptoms in the United States and Europe. [1] [2] [3] [4] It has been studied for use by rectal administration in the treatment of prostate cancer in men as well. [5] The medication was introduced in the U.S. in 1947 by Schering as Synestrol and in France in 1948 as Cycladiene. [4] Dienestrol is a close analogue of diethylstilbestrol. [6] It has approximately 223% and 404% of the affinity of estradiol at the ERα and ERβ, respectively. [7]
Dienestrol diacetate (brand names Faragynol, Gynocyrol, others) also exists and has been used medically. [2]
Diethylstilbestrol (DES), also known as stilbestrol or stilboestrol, is a nonsteroidal estrogen medication, which is presently rarely used. In the past, it was widely used for a variety of indications, including pregnancy support for those with a history of recurrent miscarriage, hormone therapy for menopausal symptoms and estrogen deficiency, treatment of prostate cancer and breast cancer, and other uses. By 2007, it was only used in the treatment of prostate cancer and breast cancer. In 2011, Hoover and colleagues reported on adverse health outcomes linked to DES including infertility, miscarriage, ectopic pregnancy, preeclampsia, preterm birth, stillbirth, infant death, menopause prior to age 45, breast cancer, cervical cancer, and vaginal cancer. While most commonly taken by mouth, DES was available for use by other routes as well, for instance, vaginal, topical, and by injection.

Compared to testosterone, androstanolone (DHT) is less likely to aromatize into estrogen, and therefore it shows less pronounced estrogenic side effects, such as gynecomastia and water retention. On the other hand, androstanolone (DHT) show more significant androgenic side effects, such as acne, hair loss and prostate enlargement.
