Hyperprolactinaemia and Ovulation (2)	

During therapy, the basal body temperature chart (Fig. 4.17) showed a normal biphasic pattern, but following withdrawal of bromocriptine, prolactin levels rose to more than 100ng/ml (2,000mu/l), galactorrhoea returned, and the temperature pattern immediately became monophasic. Although the patient did not become amenorrhoeic, she developed irregular (presumably anovulatory) periods. Following reinstitution of therapy two weeks, the patient ovulated, demonstrating a postovulatory temperature rise. She has subsequently had a regular cycle and three successful pregnancies, each with the help of bromocriptine.
