General Information

Testosterone Is the major androgenic hormone in men; Its synthesis takes place almost exclusively in testicular Leydig cells. Testosterone secretion is controlled by melatoninizing hormone (LH) produced by the pituitary gland and is subject to negative feedback through the hypothalamus and pituitary gland. The major component of circulating testosterone is bound to the sex hormone-binding globulin (SHBG).

Testosterone is involved in the formation of male sex marks, as well as in the maintenance of prostate and testicular bladder function.

When should we take the test?

In men:

  • Suspected androgen deficiency: primary hypogonadism, hypopituitarism, Kleinfelter syndrome, Down syndrome, delayed puberty, sexual impotence, infertility, estrogen therapy, cirrhosis of the liver;
  • Clinical suspicion of androgen excess: tumors of the adrenal cortex, early puberty.

In women:

Hirsutism, anovulation, amenorrhea, or virilization (possible causes: polycystic ovary syndrome, virilizing ovarian tumors, adrenal cortex, or adrenogenital syndromes).

Possible interpretation of the results

In men Low levels of testosterone Is a sign of hypogonadism. This in turn can be primary, secondary or tertiary.

Primary hypogonadism is characterized by low levels of testosterone but high levels of pituitary hormones - FSH and LH.

Secondary and tertiary hypogonadism, also called hypogonadotropic hypogonadism, have low or disproportionately normal LH / FSH levels.

Level increase is related to:

  • Itzenko-Cushing disease and syndrome;
  • Adrenogenital syndrome (women);
  • Testosterone-producing tumors (men);
  • XYY chromosome set (male);
  • Ovarian malignancy (women);
  • Decreased sex hormone-binding globulin (SHBG).

Additional information

In women, much smaller amounts of testosterone and dihydrotestosterone are produced. The ovaries and adrenal glands make a small contribution Androgens In synthesis. Testosterone produced in women is the result of peripheral conversion of steroids. Physiologically, androgens do not have any specific effect in women, but if the amount of this hormone increases (hyperandrogenemia), hirsutism (male type obesity in women) develops or even virilization (muscle growth is added to hirsutism, androgenetic alopecia, alopecia areata).

How to prepare for the test?

The test should be performed on an empty stomach.
