Clomiphene, also known as Clomid, Clomifene, or Serophene, is a synthetic non-steroidal compound that belongs to the triphenylethylene group. It is not an endogenous hormone but is used in hormone management, primarily in reproductive medicine. Clomiphene is produced synthetically and is classified as a selective estrogen receptor modulator (SERM). Researchers have extensively studied its role in fertility treatments. Clomiphene's primary physiological role is to induce ovulation in women who are anovulatory or oligo-ovulatory. It has been a subject of research in areas such as polycystic ovary syndrome (PCOS) and male infertility. Researchers have found that clomiphene can also be used to treat certain cases of male hypogonadism. The mechanism of action of clomiphene involves its interaction with estrogen receptors in the hypothalamus. By binding to these receptors, clomiphene inhibits the negative feedback of estrogen on the gonadotropin-releasing hormone (GnRH) secretion, leading to an increase in the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which stimulates ovulation. Clomiphene is primarily administered orally. Researchers have observed that it has a variable half-life, with an average of 5 to 7 days, due to its enterohepatic recirculation and high lipid solubility. It is metabolized in the liver and excreted primarily through feces. Clomiphene is clinically used to treat female infertility due to ovulatory dysfunction. It is approved by regulatory agencies such as the FDA for this purpose. Researchers have found that it is generally well-tolerated, though it may cause side effects such as hot flashes and ovarian hyperstimulation syndrome. Clomiphene is not a controlled substance but requires a prescription for use.
