Ovulation induction is a safe and effective means of restoring fertility in many of our female patients who do not ovulate or who ovulate infrequently. Additionally, it is used to produce multiple follicular development to have more opportunity for possible fertilization in the embryology laboratory. The preparations used for ovulation induction are gonadotrophins containing FSH that cause the eggs to develop towards maturity. During the stimulation phase we monitor the ovarian response with ultrasound examinations to follow follicular development and perform blood tests for evaluation of egg maturity.
