    Abstract:
    Serum testosterone, dihydrotestosterone, delta 4-androstendione and 17 beta-estradiol, sex hormone binding globulin (SHBG) and gonadotropic response to luteinizing hormone releasing hormone (LHRH) were studied in 34 male subjects with episodic or chronic cluster headache (CH). The sex steroid free fractions and those bound to SHBG and albumin were determined by a simulatory computerized method based on the mass action law. Individual steroid values were dispersed over a wide range in CH patients. Total, free and carrier protein-bound testosterone levels were significantly diminished only in chronic CH, where luteinizing hormone (LH) peak values after intravenous administration of LHRH were also decreased. Basal and peak follicle stimulating hormone (FSH) levels were significantly increased in episodic and in chronic CH groups, in comparison to healthy controls.
