Pituitary sensitivity to 50 micro g LH/FSH-RH in subjects with anorexia nervosa in acute and recovery stages.

Abstract
Gonadotrophic output was measured in response to a 50-mug dose of luteinizing hormone/follicle stimulating hormone-releasing hormone (LH/FSH-RH) in subjects with anorexia nervosa. A diminished response was found in subjects of low body weight, and in some a response occurred with increments of plasma FSH greater than those of LH. With restoration of body weight the response to the releasing factor was similar to that usually observed in healthy men and women.
