Tschugguel, W., & Berga, S. L. (2003). Treatment of functional hypothalamic amenorrhea with hypnotherapy. Fertility & Sterility, 80(4), 982-985. The objective of this uncontrolled clinical study was to determine the effects of hypnotherapy on resumption of menstruation in patients with functional hypothalamic amenorrhea (FHA). Twelve consecutive women with FHA were selected and received a single 45- to 70-minute session of hypnotherapy. The patients were observed for 12 weeks. They were asked whether or not menstruation resumed and whether or not well-being and self-confidence changed. Within the 12 weeks, 9 out of 12 patients (75%) resumed menstruation. all of the patients, including those who did not menstruate, reported several beneficial side effects such as increased general well-being and increased self-confidence. The authors concluded that hypnotherapy could be an efficacious and time-saving treatment option that also avoids the pitfalls of pharmacological modalities for women with FHA
