The association between varicocele, premature ejaculation and prostatitis symptoms: possible mechanisms

Area of Science:

• Andrology
• Urology
• Reproductive Medicine

Background:

• Systematic evaluation of varicocele's impact on male sexual function is lacking.
• Varicocele is a common condition affecting male reproductive health.

Purpose of the Study:

• To evaluate the impact of varicocele on sexual function in men with sexual dysfunction.
• To investigate the association between varicocele and prostatitis in men undergoing infertility evaluation.

Main Methods:

• Two cross-sectional studies involving 2,448 (study 1) and 139 (study 2) male subjects.
• Clinical grading of varicocele (Dubin criteria) and hormonal assessments in study 1.
• Color-Doppler ultrasonography (CDU), seminal analysis, and prostatitis markers (interleukin-8) in study 2.

Main Results:

• Severe varicocele correlated with reduced testicular volume, elevated LH, FSH, and prolactin levels.
• Premature ejaculation was significantly more prevalent in men with varicocele (29.2% vs. 24.9%).
• Varicocele was associated with prostatitis signs, symptoms, and elevated seminal interleukin-8 levels.

Conclusions:

• Prostatitis signs and symptoms are more frequent in varicocele patients.
• Varicocele is associated with an increased incidence of premature ejaculation.
• Clinical and ultrasonographic evaluation of varicocele is crucial for assessing associated sexual and prostate health issues.
