HCG Driada Medical (Human chorionic gonadotropin) is a polypeptide hormone that contains an alpha sub-unit that is similar to the alpha components of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH) and a beta sub-unit that has a different amino acid sequence.
This means that HCG Driada Medical (Human chorionic gonadotropin) exerts nearly identical effects as LH in activating the production of gonadal steroid hormones to produce androgens and progesterone and in influencing the development of male secondary sex characteristics and in normal menstrual cycle for women, but it has a weak FSH activity. It sustains the corpus luteum during pregnancy.
HCG Driada Medical (Human chorionic gonadotropin) and other gonadotropins are synthesized in the body and are not xenobiotics, so allergic reactions are rare. Chorionic gonadotropin is a hormone that is produced by the placenta during pregnancy and then excreted unchanged in the urine, from where it is extracted and purified to obtain drugs.
