The standard range for normal testosterone (eugonadal) levels in men is 300 to 1,000 nanograms per deciliter (ng/dL). But it’s totally normal for your testosterone to fluctuate throughout your ...
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 ...
Some cases of KS/HH appear to reverse during adult life where the HPG axis resumes its normal function and GnRH, LH, and FSH levels return to normal levels. This occurs in an estimated 10 to 22% of people, primarily cases of normosmic congenital hypogonadotropic hypogonadism (CHH) rather than KS cases and only found in people who have undergone ...
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] Hypogonadism is often discovered during evaluation of delayed puberty, but ordinary delay, which eventually results in normal pubertal development, wherein reproductive function ...
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.

[12] Up to 69% of female athletes practicing these sports (e.g. long-distance runners, gymnasts, ballet dancers, swimmers) can be affected by FHA, as disordered eating is ...
