This is because hypogonadism is an abnormality, whereas menopause is a normal change in hormone levels. In any case, the LH and FSH levels will rise in cases of primary hypogonadism or menopause, while they will be low in women with secondary or tertiary hypogonadism. [7]
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. [19] If high FSH levels occur during the reproductive years, it is abnormal. Conditions with high FSH levels include:
Cycle day 3 is chosen because at this time the estrogen level is expected to be low, a critical feature, as FSH levels are subject to a negative feedback. Thus any determination of FSH needs to include the corresponding estradiol level to indicate that the FSH level was drawn when the estrogen level was low. In a patient with infrequent ...
High follicle-stimulating hormone levels and low estradiol might indicate menopause, but of course, if you’re younger than typical menopause age, you should also rule out pregnancy with a ...
The rates for spontaneous pregnancy in older women with elevated FSH levels have not been studied very well and the spontaneous pregnancy success rate, while low, may be underestimated due to non reporting bias, as most infertility clinics will not accept women over the age of forty with FSH levels in the premenopausal range or higher.
Levels of LH/FSH may be suppressed by a raised prolactin level, and are therefore not interpretable unless prolactin is low or normal. In men, the combination of low LH and FSH in combination with a low testosterone confirms LH/FSH deficiency; a high testosterone would indicate a source elsewhere in the body (such as a testosterone-secreting ...
If a uterus is present, LH and FSH levels are used to make a diagnosis. [13] Low levels of LH and FSH suggest delayed puberty or functional hypothalamic amenorrhea. [13] Elevated levels of FSH and LH suggest primary ovarian insufficiency, typically due to Turner syndrome. [13] Normal levels of FSH and LH can suggest an anatomical outflow ...
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.
