Low testosterone symptoms in men vary widely, especially across different age groups. ... This test is less common, but some experts think it’s a more accurate indicator of low T. LH and FSH test.
Some men with normal total testosterone have low free or bioavailable testosterone levels which could still account for their symptoms. Men with low serum testosterone levels should have other hormones checked, particularly luteinizing hormone to help determine why their testosterone levels are low and help choose the most appropriate treatment ...
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.

Treatment for both males and females with KS/CHH normally consists of one of three options which can be used for both hormone replacement therapy and/or fertility treatment. [3] [4] Sex hormone replacement (testosterone or oestrogen & progesterone). Gonadotropin therapy (medications that replicate the activity of FSH and LH). GnRH pulsatile ...
Aromatase deficiency is a rare condition characterized by extremely low levels or complete absence of the enzyme aromatase activity in the body. [2] It is an autosomal recessive disease resulting from various mutations of gene CYP19 (P450arom) which can lead to ambiguous genitalia and delayed puberty in females, continued linear growth into adulthood and osteoporosis in males and virilization ...
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 ...
In the female, the goal for gonadotropin therapy is to obtain ovulation. This is obtained with FSH treatment followed by hCG or LH to trigger ovulation. FSH will stimulate granulosa cells for follicular maturation while LH will act on luteal cells to produce steroids aiding follicular maturation and preparing the endometrium for pregnancy.
During puberty and adulthood, low testosterone levels with increased levels of the pituitary hormones FSH and LH in the blood can indicate the presence of Klinefelter syndrome. A spermiogram can also be part of the further investigation. Often, an azoospermia is present, or rarely an oligospermia. [14]
