Disorders of menstruation and ovulation are relatively common in women of reproductive age. Possible disorders range from minor to potentially life threatening. To diagnose and treat such menstrual disorders appropriately, an understanding of normal puberty and of the normal menstrual cycle is required (see Chap. 91 and Chap. 95).

Although disorders of sexual response also occur with some frequency, they are often overlooked by physicians. Women seeking assistance may have other complaints, and only a sensitive clinician is able to discern the true reason for the visit. However, disorders of sexual response, although not life threatening, may significantly affect the life of the patient and her sexual partner. A knowledge of normal sexual responses and the willingness to discuss such issues openly with patients contribute to successful resolution of the problems.
