Human chorionic gonadotropin (HCG) is a natural hormone produced by placenta; it is obtained from the urine of pregnant women. The mechanism of action of HCG is the same as of the luteinizing hormone (LH) produced in the pituitary gland. HCG stimulates the production of progesterone and estradiol in ovaries.
Intramuscular administration of HCG to women with confirmed mature Graafian follicles causes ovulation after approx. 38-42 hours from the injection.
Potential side effects: pain at the injection site, headache, fatigue, vomiting, nausea, abdominal pain, depression, irritability, anxiety, diarrhea, breast pain.
