Endocrine studies during the refeeding of young women with nutritional amenorrhea and infertility.
Serial endocrine studies were performed during the refeeding of a group of nine young women who presented with amenorrhea associated with injudicious dieting. No significant psychopathology was disclosed by the Lanyon Psychological Screening Inventory in any of the patients, six of whom were single and three married and infertile. The mean weight before refeeding was 81.6% of the normal for height. The mean initial serum follicle-stimulating hormone concentration was within the limits of normal for young women of reproductive age, but the serum luteinizing hormone (LH) concentration and the vaginal maturation score were low. As weight was regained, the serum LH concentration increased (the pooled r for LH versus percent normal weight = 0.85) and the vaginal maturation score rose (the pooled r for vaginal maturation score versus percent normal weight = 0.93). When a mean weight of 96.6% of normal was reached after a mean of 5.3 (range, 2 to 11) months of refeeding, spontaneous menses occurred. The initial cycle was ovulatory in two instances and anovulatory in five, as determined by basal body temperature patterns, plasma progesterone concentrations, and endometrial biopsies. With continued weight gain, menstruation became regular and the three married patients conceived.
