An antigonadotropin is a drug which suppresses the activity and/or downstream effects of one or both of the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH). This results in an inhibition of the hypothalamic-pituitary-gonadal (HPG) axis , and thus a decrease in the levels of the androgen , estrogen , and ...
GnRH modulators affect the secretion of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn affects the gonads, influencing their function and hence fertility as well as the production of sex steroids, including that of estradiol and progesterone in women and of testosterone in men.
Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production.

Chemical structure of the endogenous androstenedione. In the human body, the enzyme aromatase converts androstenedione to estrogen. Aromatase is an enzyme that belongs to the cytochrome P450 family located on chromosome 15. In the human body, the aromatase consists of 10 β-strands (1 major sheet and 3 minor sheets) and 12 α-helixes.
Antihormone therapy blocks hormones from sending these messages to cells. If a diagnostic test shows cancer in places with hormones attached, drugs may be prescribed to the patient to block the receptors and inhibit the growth of cancer cells. [3] Most antihormone therapies are administered by pill for 5 to 10 years after surgery. [4]
This elevation in FSH is important for the recruitment of a new cohort of ovarian follicles in the subsequent cycle. [15] After menstruation begins, FSH levels decrease due to estrogen's negative feedback and inhibin B produced by the developing follicle. FSH stimulates aromatase activity in granulosa cells, converting androgens to estrogen.
Ovarian stimulation with the aromatase inhibitor letrozole has been proposed for ovulation induction in order to treat unexplained female infertility. In a multi-center study funded by the National Institute of Child Health and Development, ovarian stimulation with letrozole resulted in a significantly lower frequency of multiple gestation (i.e., twins or triplets) but also a lower frequency ...
Aromatase inhibitors are an important class of drugs used for the treatment of breast cancer in postmenopausal women. At menopause, estrogen production in the ovaries ceases, but other tissues continue to produce estrogen through the action of the enzyme aromatase on androgens produced by the adrenal glands. When the action of aromatase is ...
