Serum testosterone and gonadotropins levels in patients with premature ejaculation: A comparison with normal men.

BACKGROUND

To investigate the role of testosterone (T) in the pathogenesis of ejaculatory symptoms, particularly premature ejaculation (PE).

MATERIALS AND

METHODS

A total of 41 male patients with PE as well as 41 controls with no sexual dysfunction were recruited in this cross-sectional study. We used the stopwatch measurement to monitor the intravaginal ejaculatory latency time (IELT). Patients with mean IELT values lower than 60 s were considered to have PE. Serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), total testosterone (TT) and free testosterone (FT) were measured in patients as well as controls. Patients with thyroid dysfunction, hypogonadism, hypertension and dyslipidemia were excluded from the study.

RESULTS

The serum levels of FT and FSH were significantly higher in cases (P = 0.036 and 0.003, respectively). There was no significant difference between TT, LH and PRL levels of the two groups.

CONCLUSION

Patients with PE have higher FT and FSH levels compared with normal men. The causative relationship between these entities and also the clinical importance of this finding has to be determined by more comprehensive studies.
