The relationship between testosterone levels and Peyronie's disease

Area of Science:

• Andrology
• Urology
• Endocrinology

Background:

• The etiology of Peyronie's disease (PD) remains unclear, with theories suggesting connective tissue disorders or impaired wound healing.
• Androgens, particularly testosterone, influence collagen metabolism and wound healing, prompting investigation into their role in PD.

Purpose of the Study:

• To investigate the potential relationship between Peyronie's disease and low serum total testosterone levels.

Main Methods:

• A case-control study involving 147 men with PD and 137 healthy controls.
• Collected demographic data, medical history, physical examination findings, and erectile capacity.
• Measured serum total testosterone levels via early morning blood samples after an overnight fast.

Main Results:

• Mean serum total testosterone levels were slightly lower in men with PD (3.9 ± 1.1 ng/ml) compared to controls (4.2 ± 1.7 ng/ml), but this difference was not statistically significant (p = 0.062).
• No statistically significant correlation was found between PD and low testosterone levels.
• Penile plaque dimensions and degree of penile curvature did not correlate significantly with testosterone levels.

Conclusions:

• This study did not find a statistically significant association between Peyronie's disease and low serum total testosterone levels.
• Further large-scale, randomized, controlled prospective studies are necessary to definitively establish any potential link between testosterone levels and PD.
