Pituitary gonadal system function in patients with erectile impotence and premature ejaculation

Arch Sex Behav. 1979 Jan;8(1):41-8. doi: 10.1007/BF01541211.


The pituitary testicular system was studied in men with psychogenic impotence. Eight patients with primary erectile impotence age 22--36 years, eight men with secondary erectile impotence age 29--55 years, and 16 men with premature ejaculation age 23--43 years were studied. The last group was further divided into two subgroups: E1 (n = 7) patients without and E2 (n = 9) patients with anxiety and avoidance behavior toward coital activity. Sixteen normal adult men age 21--44 served as a control group. Diagnosis was made after psychiatric and physical examinations. Patients complaining primarily of loss of libido were not considered in the study. Ten consecutive blood samples were obtained over a period of 3 hr from each patient. Luteinizing hormone (LH), total testosterone, and free (not protein-bound) testosterone were measured. Statistical analysis revealed no significant differences between patients and normal controls.
