Analyzes for hormones

Steroid binding globulin in the blood

Steroid binding globulin is a protein that binds and transports testosterone and estradiol. Protein-bound hormones are not biologically active. In addition to its transport function, the steroid-binding globulin protects testosterone and estradiol from metabolic inactivation along the way from the gland secreting to the target organ, and forms a kind of hormone depot in the body.

Dihydrotestosterone in the blood

Testosterone and dihydrotestosterone in the cell bind to the same receptor, but the affinity of testosterone to the receptor is significantly lower than that of dihydrotestosterone. Only dihydrotestosterone affects the prostate gland, skull bones and hair growth. DGT is metabolized to 3α-androstenediol-glucuronide.

Testosterone in the blood

Testosterone is an androgenic hormone responsible for secondary sexual characteristics in men. The most important source of testosterone is Leidig cells of the testes. Testosterone supports spermatogenesis, stimulates the growth and function of additional sexual glands, as well as the development of the penis and scrotum.

Androgens

The main representatives of androgens in the female body are testosterone, androstenedione and DHEAS. Androgens stimulate the growth of hair on the pubic and axilla, increase libido and affect the size of the clitoris and large labia. Androgens modulate the production of gonadotropins in the anterior pituitary gland.

Progesterone in the blood

Progesterone promotes the proliferation of the mucous membrane of the uterus, facilitates the implantation of a fertilized egg. Progesterone is synthesized by a yellow body, and during pregnancy, the placenta becomes its main source.

Estradiol in the blood

Estradiol - the main representative of estrogen, which has the highest biological activity. Estrone is formed from estradiol by an enzymatic route and has less pronounced biological activity (due to its low ability to bind to cell receptors).

Sexual Steroid Hormones

In the female body, the most important sex steroids are formed in the ovaries and adrenal cortex, and during pregnancy - in the placenta. The main sex steroids of the male body (androgens) are synthesized in the testicles and, in a small amount, in the adrenal cortex.

Prolactin in the blood

Prolactin is synthesized in specialized lactogenic cells in the anterior lobe of the pituitary gland; its synthesis and release is under the stimulatory-inhibitory influence of the hypothalamus.

Luteinizing hormone in the blood

Luteinizing hormone is the peptide hormone of the anterior lobe of the pituitary gland. Targets of luteinizing hormone in women include ovarian cells and the yellow body. Luteinizing hormone stimulates ovulation and activates in ovarian cells the synthesis of estrogens and progesterone. It activates the synthesis of testosterone in the cells of the Leidig testis in men

Follicle-stimulating hormone in the blood

Follicle-stimulating hormone is a peptide hormone secreted by the anterior pituitary gland. In women, follicle-stimulating hormone controls the growth of follicles before their maturity and readiness for ovulation.
