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.
In others, particularly with coexistent depression, symptoms such as decreased quality of life can be severe. [9] Hormonally, POI is defined by abnormally low levels of estrogen and high levels of FSH, which demonstrate that the ovaries are no longer responding to circulating FSH by producing estrogen and developing fertile eggs. The ovaries ...
It is usually accompanied by high FSH (follicle stimulating hormone) levels. Quality of the eggs may also be impaired. [2] [3] However, other studies show no association with elevated FSH levels and genetic quality of embryos after adjusting for age. The decline in quality was age related, not FSH related as the younger women with high day ...
It is identified by lab tests that show low testosterone accompanied by low to normal FSH and LH levels. Remember, you may have low T if your total testosterone levels are below 300 ng/dL and you ...
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]
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. [20] If high FSH levels occur during the reproductive years, it is abnormal. Conditions with high FSH levels include:
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.
The surge of GnRH/LH/FSH in non KS/HH children gives detectable levels of testosterone in boys and oestrogen and progesterone in girls. The lack of this surge can sometimes be used as a diagnostic tool if KS/HH is suspected in a newborn boy, but is not normally distinct enough for diagnosis in girls.
