Sex hormones are steroidal hormones synthesized by the gonads, the placenta and the reticular zona of the adrenal cortex, including estrogen, progesterone and androgens. Estrogen and progesterone are mainly secreted by the ovaries, and androgens are mainly secreted by the testes.
1. Estrogen: its role is to promote the development of the ovaries and uterus, the development of follicles as well as the proliferation of the uterine lining, so that menstruation comes normally.
2. Progesterone: It can transform the endometrium from the proliferative phase to the secretory phase to prepare for the fertilization of the egg, prevent uterine contractions during pregnancy and maintain the stability of the fetus.
3. Androgens: can increase protein synthesis, promote the production of red blood cells, promote the development of male secondary sexual characteristics during puberty, as well as testicular development and sperm formation.
Sex hormones are closely related to a person’s fertility. If there are abnormalities in sex hormones, it is necessary to consult a doctor in time for intervention and treatment under the doctor’s guidance.
