What is normal testosterone level?

The male reproductive organs include many elements, which, like the female endocrine, have very important value. First of all, men should test their testosterone regularly. If it is not within the normal range, it will affect the health of sperm and cause fertility problems. What is the normal testosterone level and some hormone issues in the male body? What are the relevant introductions?

Normal value

During the follicular phase of the normal female menstrual cycle, the average serum testosterone concentration is 0.43ng/ml, with a high limit of 0.68ng/ml. If it exceeds 0.7ng/m1 (equal to 2.44nmol/L), it is called hypertestosteronemia or hyperandrogenemia. Adults: Male 14-25.4nmol/L Female 1.3-2.8nmol/L Children Male <8.8nmol/L Female <0.7nmol/L Pregnancy 2.7-5.3nmol/L.

Clinical significance

Increased: idiopathic male precocious puberty, familial male precocious puberty, adrenal cortical hyperplasia, adrenal cortical tumor (adenocarcinoma increases significantly, adenoma also often increases), testicular tumor, testicular feminization, polycystic ovary syndrome, ovarian virilization tumor, pineal tumor, idiopathic hirsutism, hypothyroidism, androgen, HCG and estrogen treatment are moderate.

Decrease: Trisomy 21, uremia, myotonia, liver dysfunction, trapped testis, primary or secondary hypogonadism (Klinefelter syndrome, Kallman syndrome, etc.), after discontinuation of androgen therapy, etc.

Barbiturates, clomiphene, gonadotropins, and oral contraceptives can increase testosterone levels; androgen, dexamethasone, digoxin, and alcohol can lower the results.

People who need to be examined: men over 40 years old, men with sexual dysfunction, women with endocrine disorders, etc.
