Hypergonadotropic Ovarian Failure
A progonadotropin, or hypergonadotropin, also known as a gonad stimulant, is a type of drug which increases the secretion of one or both of the major gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This, in turn, results in increased function and maintenance of the gonads and increased gonadal steroidogenesis of sex hormones such as androgens, estrogens, and progestogens. Progonadotropins are the functional opposites of antigonadotropins. They have clinical applications in the treatment of hypogonadism and infertility. Conversely, hypergonadotropic effects can occur as a side effect of some drugs. Examples of progonadotropic drugs include gonadotropin-releasing hormone (GnRH) GnRH agonist, agonists when administered in a pulsatile (as opposed to continuous) manner, antiestrogens such as tamoxifen, clomifene, fulvestrant, and aromatase inhibitors like anastrozole, and, only in men, pure antiandrogens such as flutamide, bicalutamide, enzalutamide, and ...

Clomifene
Clomifene, also known as clomiphene, is a medication used to treat infertility in women who do not ovulate, including those with polycystic ovary syndrome. Use results in a greater chance of twins. It is taken by mouth once a day, with a course of treatment that usually lasts for five days. Common side effects include pelvic pain and hot flashes. Other side effects can include changes in vision, vomiting, trouble sleeping, ovarian cancer, and seizures. It is not recommended in people with liver disease or abnormal vaginal bleeding of unknown cause or who are pregnant. Clomifene is in the selective estrogen receptor modulator (SERM) family of medication and is a nonsteroidal medication. It works by causing the release of GnRH by the hypothalamus, and subsequently gonadotropin from the anterior pituitary. Clomifene was approved for medical use in the United States in 1967. It is on the World Health Organization's List of Essential Medicines, under the category "Ovulation induc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
