What are the normal androgen levels?
normal androgen levels in a human being vary according to sex, age and other factors. Androgens, a category that includes chemicals such as testosterone, dihydrotestosterone and dehydroepiandrosterone are hormones responsible for the production of men's sexual properties, a process called virilization. They are also present in lower quantities in women. Normal levels of primary androgen, testosterone, in adult men may be up to 270 nanograms per deciliter (NG/DL) and up to 1,080 ng/dl, depending on age, while women usually have 70 ng/dl or less. Abnormal levels of androgens can cause health problems and other abnormalities in both men and women and excess or insufficient amounts of androgens during childhood or uterus can affect development. In the next two decades of life and between 35 years, it drops to 350 to 890 ng/DL0 and 720 ng/dl after the age of 60. Predubescent boys usually have less than 30 ng/dl, but their late adolescents rise between 100 and 540 ng/dl by their middle adolescentsand up to 970 ng/dl. This change brings the maturation of reproductive organs, along with other physical changes, such as increased muscle mass, increased facial and body and deeper voice.
women usually have a much lower amount of androgens in their bodies, but they are more physiologically sensitive to them. Premenopausal adult women have normal testosterone levels between 10 and 70 ng/d. This amount usually triples or four times during pregnancy and after menopause decreases to less than 40 ng/dl. Preubertal girls usually have less than 10 ng/dl and are rising to 8-53 ng/dl during adolescence. An abnormally high amount of androgens in the female body can cause the development of male secondary sexual sexual properties a deeper voice, increased muscle mass and increasing the growth of face and body hair, as well as symptoms such as acne and menstrual abnormalities.
androgens in the womb, and especially dihydrotestosterone, are importantrye influence on fetal development, causing the development of penis, scrotum and other components of the male reproductive system. Abnormal androgen levels can cause abnormalities of sexual development, such as congenital adrenal hyperplasia, in which a child that is genetically feminine develops partially male properties or ambiguous genitals. In childhood, abnormal levels of androgens can cause delayed or premature puberty.
Some men's bodies produce abnormally low levels of testosterone or other androgens, a condition called hypogonadism. Common symptoms include reduced muscle mass, reduced beard and body hair growth and sexual dysfunction such as impotence or infertility. Hypogonadism has a number of potential causes, including genetics, infection, and malnutrition. The most common congenital cause of hypogonadism in men is the clinfelter syndrome, a genetic disorder caused by the presence of extra x chromosome.
The effects of low levels of androgen in women are less dramatic, but they can includenovate the loss of sexual desire. In both sexes, it can reduce the production of androgens and especially reduced testosterone production cause depression, anxiety or obesity. It also increases the risk of conditions such as heart disease and osteoporosis.
