Effect of Microsurgical Varicocele Repair on Sperm Capacitation and Probability of Generating a Pregnancy as Measured by Pre and Postoperative Novel Testing With Cap-Score.

Objective: To study whether varicocele repair would improve sperm capacitation and probability of generating a pregnancy.

Methods: Data were collected prospectively from 40 consecutive adult men who presented with infertility confirmed by semen analysis (SA) and found to have a varicocele on exam or ultrasound who underwent unilateral or bilateral subinguinal microscopic varicocelectomy. We recorded pre and postoperative SA, Cap-Score, and probability of generating a pregnancy (PGP) with a 3-month follow-up.

Association Between Prostate Zonal Volume and Erectile Dysfunction in Patients With Benign Prostatic Hyperplasia.

Introduction: The impact of prostate zonal volume on erectile function and penile Doppler parameters is not yet settled.

Aim: To assess the association between prostate zonal volume and erectile dysfunction in patients with benign prostatic hyperplasia.

Methods: This cross-sectional analytical study included 70 men (aged ≥ 40 years).

Impact of Subinguinal Varicocelectomy on Serum Testosterone to Estradiol Ratio in Male Patients With Infertility.

Objective: To assess the effect of varicocele and subsequent varicocelectomy on testosterone-estradiol ratio in patients presented with infertility or testicular pain.

Materials And Methods: In this prospective, controlled, clinical study, 135 men were assigned to 3 equal groups (n = 45 per group). The varicocele-treated "varicocelectomy" group included patients with varicocele who underwent loupe-assisted subinguinal varicocelectomy for infertility or testicular pain; the varicocele-not-treated "positive control" group included patients with varicocele who refused or who wished to postpone varicocelectomy; and the no-varicocele "negative control" group included fertile men without varicocele.
