One of the major causes of female infertility is either complete absence of or abnormal ovulation. Successful production of oocytes is influenced by numerous hormones with very delicate balances that create the woman's normal cycle. Frequently the production is off balance, resulting in poor or no ovulation. A more important step to restoring good ovulation is to attempt to reestablish a balance of hormones through fertility drugs such as clomiphene citrate (Siphene), HMG (human menopausal gonadotropin), FSH (follicle stimulating hormone), or hCG (human chorionic gonadotropin). To maximize the chances for success it is necessary to measure these hormones through blood tests, as well as evaluate the growth and development of the follicles containing eggs by ultrasound assessment.
Opportunities for conception are significantly increased by timed intercourse to ovulation. This is determined through hormonal and ultrasound monitoring. Patients with ovulatory dysfunction are treated with fertility medications.
