Some women have irregular menstrual cycles and don’t produce an egg each month. This is called anovulation. Causes of anovulation are many and can be due to one or a combination of factors. These include stress, weight loss or weight gain, or excessive production of a hormone called prolactin and Polycycstic Ovarian Syndrome. Ovulation Induction (OI) aims to restore ovulation.
OI involves the woman taking fertility drugs either in the form of tablets or injections, to help the ovaries produce and release a single egg each month. Injections are only used if there is no response to the milder tablets that are prescribed. The way the patient responds to taking the medication is monitored with a series of transvaginal ultrasound scans and hormone blood tests.
