Sex Hormone

Sex Hormone is a steroid hormone that is produced primarily in the ovaries and testicles. It plays an important role in the regulation of human sexual development and the formation of its reproductive function.

There are two main types of sex hormones: female and male. Estrogen and progesterone are female sex hormones; androgens are male sex hormones.

Female sex hormones begin to be produced in girls in the womb. They regulate the menstrual cycle and determine the development of the reproductive organs. Progesterone, in turn, prepares the uterus for implantation of a fertilized egg.

Male sex hormones begin to be produced in the testicles of boys already during intrauterine development. Androgens are directly involved in the formation of secondary sexual characteristics, such as muscle development, hair growth and changes in voice timbre.

Sex hormones play an important role in human mental and physical health. Impaired production of sex hormones can lead to various diseases, such as infertility, menstrual irregularities, obesity and others. Therefore, it is important to monitor your health and undergo regular medical examinations.

Extract from the medical encyclopedia “Sex hormone (Greek sex - sex, hormao - set in motion, excite, encourage)” - steroid hormones produced primarily (in men - in the testicles, in women - in the adrenal glands and ovaries) and regulating the sexual functions of the body through a series of intermediate effects on the endocrine glands. Currently, about 50 sex hormones are known. Steroid nature. Their classification is based on the structure of the molecule, features of biological action and functional purpose. All male sex hormones belong to the androgen class, female hormones are divided into estrogens (estradiol, estriol) and progestins. A smaller part, the so-called intermediate VTs (human testosterone, SHBG, etc.), refers to mixed estrogen-androgen forms. Female genital fatty acids are usually secreted in large quantities by the same cells (female gonads), and only small amounts of male reproductive fatty acids are synthesized in a woman’s body during pregnancy as a kind of protective reaction to the progression of pregnancy (primordial complex). Male genital VTs, on the contrary, are weakly expressed or not secreted at all in women and appear in their cells only during pregnancy due to the transformation (rearrangement) of the female genome during prenatal development of the fetus. In human ontogenesis, sex VTs closely interact with pituitary hormones and stimulate the synthesis of sex VTs and androgens in target organs. The target organs that are sensitive to sexually transmitted VT are the same organs that serve as targets for their action in men. Under the influence of certain proportions of fatty acids, the rate of sperm synthesis increases, the testicular epithelium is activated, the number and maturity of follicles increases, etc. Since the set and activity of VTs and glands that make up male and female VTs are different, this leads to different effects on target organs. There are also gender differences in the sensitivity of body tissues to the action of certain sex hormones, which indicates the participation of their systemic regulation. It has been established that the androgen and estrogen systems normally influence some human organs in different directions, causing the opposite effect, that is, we can talk about the phase effect of the action of female genital fatty acid cycles and fatty acids. VT is controlled by negative (estrogens and estrone) and positive (androgens, progestogens) VT. They consist of the hypothalamus and the anterior pituitary gland (adenohypophysis); cells of fig cells (trophoblast choriocarcinoma, fibromodulatory activity of the placenta), salivary glands, endometrium and mammary tissue.
