Ovulation induction is a form of treatment which involves stimulation of the ovaries to bring about development of a ripened egg which can then be fertilised by a normal act of intercourse. Ovulation induction is used to treat women who do not ovulate or who ovulate irregularly. Ovulation induction can be used for women who have been diagnosed with Hypothatic Pituitary failure or women with Polycystic Ovarian Syndrome (PCO) and consequently may not be ovulating (Annovulatory)
