Pituitary adenomas account for 10-15% of all intracranial tumors and they frequently impair fertility. The development of medical and surgical therapy for such tumors has turned pregnancy into a reality for women harboring pituitary adenomas. However, gestation risks for both mother and fetus are still of concern for endocrinologists, gynecologists and pediatricians. This book intends to update knowledge on this topic, mainly regarding fertility restoration as well as gestational and post gestational management of patients with pituitary tumors.
