  2. Follicle-stimulating hormone - Wikipedia

    en.wikipedia.org/wiki/Follicle-stimulating_hormone

    The most common reason for high serum FSH concentration is in a female who is undergoing or has recently undergone menopause. High levels of FSH indicate that the normal restricting feedback from the gonad is absent, leading to an unrestricted pituitary FSH production. FSH may contribute to postmenopausal osteoporosis and cardiovascular disease ...

  3. Luteinizing hormone - Wikipedia

    en.wikipedia.org/wiki/Luteinizing_hormone

    Persistently high LH levels are indicative of situations where the normal restricting feedback from the gonad is absent, leading to a pituitary production of both LH and FSH. While this is typical in menopause, it is abnormal in the reproductive years. There it may be a sign of: Premature menopause

  4. Follicle-stimulating hormone insensitivity - Wikipedia

    en.wikipedia.org/wiki/Follicle-stimulating...

    Signs and symptoms. In females, FSH insensitivity results in diminished development of ovarian follicles and granulosa cells and low to normal estrogen levels, elevated to very elevated gonadotropin levels, and low inhibin B levels, whereas males present with diminished Sertoli cell proliferation and moderately elevated FSH levels, normal to slightly elevated LH levels, normal testosterone ...

  5. Hypergonadotropic hypogonadism - Wikipedia

    en.wikipedia.org/wiki/Hypergonadotropic_hypogonadism

    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. [1]

  6. Hypothalamic–pituitary–gonadal axis - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    The anterior portion of the pituitary gland produces luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and the gonads produce estrogen and testosterone. In oviparous organisms (e.g. fish, reptiles, amphibians, birds), the HPG axis is commonly referred to as the hypothalamus-pituitary-gonadal-liver axis (HPGL-axis) in females ...

  7. Hypogonadism - Wikipedia

    en.wikipedia.org/wiki/Hypogonadism

    Testing serum LH and FSH levels are often used to assess hypogonadism in women, particularly when menopause is believed to be happening. These levels change during a woman's normal menstrual cycle, so the history of having ceased menstruation coupled with high levels aids the diagnosis of being menopausal.

  8. Primary ovarian insufficiency - Wikipedia

    en.wikipedia.org/wiki/Primary_ovarian_insufficiency

    Two to 5% of women with POI and a premutation in FMR1, a genetic abnormality, are at risk of having a child with fragile X syndrome, the most common cause of inherited intellectual disability. [8] [6] The diagnosis is based on ages less than 40, amenorrhea, and elevated serum follicle-stimulating hormone (FSH) levels. [4]

  9. Menotropin - Wikipedia

    en.wikipedia.org/wiki/Menotropin

    Urine of postmenopausal women reflects the hypergonadotropic state of menopause-levels of follicle stimulating hormone (FSH) and luteinizing hormone (LH) are high - and contain a mixture of these gonadotropins. [2] [3] [4] Other protein substances may be present, including small amounts of human chorionic gonadotropin (hCG). [1]
