Commercially produced gonadotrophin (ovary-stimulating) hormones are used in higher than usual doses to stimulate «super-ovulation,» or more eggs than would normally be produced and brought to maturity in one cycle. The development of these oocytes is monitored by ultrasound until they are ready to be released from the ovary (ovulation). Ultrasound checks are performed at least three or four times in the early part of the cycle, sometimes every day, along with measurements of estrogen and other hormones. Maturation of the oocytes is then brought about by giving a syntheric form of luteinizing hormone, a pituitary hormone related to ovulation...
