Double-stimulation with LH-RH in primary amenorrhea caused by chronic internal hydrocephylus: a case study.
A 19-year-old female patient with primary amenorrhea and pubertas tarda due to chronic internal hydrocephalus presented with normal hormonal findings except for low estradiol and a prepubertal type of reaction in the double-stimulation test with LH-RH. After successful operative treatment with a Spitz-Holter high-pressure valve, the intracranial decompression was promptly followed by pubertal development, she began to menstruate, and the LH-RH double-stimulation test showed an adult pattern of response. The results of the test support the view that a partial deficiency in the secretion of LH-RH is the cause of hypogonadism in such a case.
