Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. [1] FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland [ 2 ] and regulates the development, growth, pubertal maturation , and reproductive processes of the body.
Increased prolactin can have an effect of the inhibition of GnRH secretion which is responsible for libido, and the releases of FSH (Follicle-stimulating hormone), LH (Luteinizing hormone), and testosterone. FSH in men is responsible to stimulate sperm production and LH is responsible for the stimulation of testosterone; with the inhibition of ...
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.

Follicle-stimulating hormone (FSH) insensitivity, or ovarian insensitivity to FSH in females, also referable to as ovarian follicle hypoplasia or granulosa cell hypoplasia in females, is a rare autosomal recessive genetic and endocrine syndrome affecting both females and males, with the former presenting with much greater severity of symptomatology.
The tests measure levels of a hormone called FSH (follicle-stimulating hormones). However, hormone levels go up and down all the time, even during the course of a day, so the test can't really pin ...
Although postmenopausal, the mother with this milder form of Sheehan's syndrome does not experience hot flushes, because the pituitary fails to secrete FSH (high levels of FSH, secreted by the pituitary in healthy postmenopausal women is an attempt to trigger ovulation, and these high levels of FSH cause hot the flushes).
Macroorchidism is related to IGFS1 deficiency, which causes an increase in the secretion of follicle stimulating hormone (FSH). There are other causes for macroorchidism, such as hypothyroidism, local tumors, and aromatase deficiency. [3] Macroorchidism can be diagnosed by measuring the testicular volume using a prader orchidometer. [4]
The diagnosis is based on age less than forty, amenorrhea, and two elevated serum follicle-stimulating hormone (FSH) and decreased estrogen measurements at one-month intervals. [10] The anterior pituitary secretes FSH and LH at high levels to try to increase the low estrogen levels that are due to the dysfunction of the ovaries.
