Resumen

DEVOTO C, Enzo  y  ARAVENA C, Lucía. Favorable reproductive and menstrual evolution in women with hypothalamic dysfunction and lack of response to clomiphene. Rev. méd. Chile [online]. 2002, vol.130, n.7, pp.745-752. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872002000700005.

Background: Hypothalamic dysfunction is a cause of menstrual disturbances in women, in whom other diseases have been discarded. This condition is characterized by a failure of the GNRH pulse generation system and is associated to psychological and environmental factors. A lack of ovulatory response to the administration of clomiphene can be a sign of bad prognosis in hypothalamic dysfunction. Aim: To report the natural history of patients with hypothalamic dysfunction and a bad or deficient response to the administration of clomiphene. Patients and methods: Fifty patients with hypothalamic dysfunction, that consulted for menstrual disturbances at the age of 15 to 20 years old, were studied. All received clomiphene and 31 had an ovulatory response, 12 had menses without ovulation and 7 did not menstruate. Of these 19 women eleven were interviewed again about their menstrual and reproductive history, after a lapse of 9 to 17 years of loss from follow up. Results: Eight of the eleven women had stressful events during adolescence (going away from family house in 3, starting university studies in 3, migration out of the natal country in one and non competitive physical activity in one). All restarted their menses and eight with active sexual life had spontaneous pregnancies, giving birth from two to five children. Ovulatory cycles were documented in women without active sexual life. Conclusions: In teenagers with hypothalamic dysfunction and menstrual disturbances, a deficient or bad response to clomiphene does not necessarily indicate a bad prognosis in terms of menses or fertility (Rev Méd Chile 2002; 130: 745-52)
