Описание
Enclomiphene is a synthetic and nonsteroidal antiestrogen. It is the more potent isomer and the one responsible for its ovulation-inducing actions. The half-life of enclomiphene is relatively short, so serum concentrations rise and fall quickly during and after treatment. Antiestrogens represent the first-line treatment strategy in WHO class-2 anovulatory infertility.

Биологическая активность
Enclomiphene is the trans-isomer of clomiphene citrate (CC). It has a higher rate of clearance and is less active than the cis-isomer, cis-clomiphene. Clomiphene citrate has been evaluated for antineoplastic activity against breast cancer.
Способ действия
Enclomiphene is a non-steroidal estrogen receptor antagonist that promotes gonadotropin-dependent testosterone secretion by the testes. The main mechanism of its action is thought to be its antagonistic effects on the hypothalamic-pituitary axis and stimulation of GnRH secretion.
