Abstract

PURPOSE:

In this study, the relationship between sex hormone levels and erectile dysfunction (ED), as well as the necessity of routinely measuring sex hormone levels were evaluated.

MATERIALS AND METHODS:

This study included one hundred patients admitted to a urology clinic for sexual dysfunction. To determine the hormone levels, following the history (included IIEF-5 score) and physical examination, triple blood samples were collected at intervals of 15 minutes between 08:00 and 10:00 am. Total and free testosterone, prolactin, follicle stimulating hormone and luteinizing hormone levels were studied.

RESULTS:

Mean age was 43 (23-80) years. IIEF-5 score was less than 21 [9.8-4.3 (3-19)] in all study groups. There was a statistically significant correlation between tT and FSH, as well as between LH and FSH in Pearson (r =-0.513, p < 0.001, respectively) and also in Spearman tests (r=-0.224, p=0.042 and r=-0.459, p < 0.001, respectively). However, there was no correlation between age and serum hormone levels (p > 0.05). Of the 100 patients, 18 (18%) had low tT, 77 (77%) had normal and 5 (5%) had high tT levels. No statistically significant correlation was found between decreased libido and tT levels (p > 0.05). Twelve (66.6%) of the 18 patients with low tT had normal libido.

CONCLUSION:

Analyzing the medical history in detail and performing a thorough physical examination can reduce the need for excessive studies and consultations, and enables patients to save time and costs.
