Bariatric Surgery Impact on Reproductive Hormones, Semen Analysis, and Sperm DNA Fragmentation in Men with Severe Obesity: Prospective Study.

Purpose: Growing evidence in the literature suggests that obesity is capable of altering reproductive hormone levels and male fertility. Effects on classic semen parameters and sperm DNA fragmentation (SDF), however, have not been properly established. Additionally, the impact of bariatric surgery (BS) on those parameters is still controversial.

Diagnostic accuracy of physical examination compared with color Doppler ultrasound in the determination of varicocele diagnosis and grading: Impact of urologists' experience.

Background: Treatment of palpable varicocele in infertile men with abnormal semen parameters is widely accepted, and physical examination (PE) remains a cornerstone for recommending varicocele repair. However, identification of clinical varicocele during PE can be challenging for both urology residents and consultants.

Objective: To compare the diagnostic accuracy of PE to color Doppler ultrasonography (CDU) for the diagnosis of varicocele in experienced and non-experienced examiners.

Complete urological evaluation including sperm DNA fragmentation in male systemic lupus erythematosus patients.

Objective: To evaluate sperm DNA fragmentation analysis in non-azoospermic male systemic lupus erythematosus (SLE) patients.

Methods: Twenty-eight consecutive male SLE patients (American College of Rheumatology criteria) and 34 healthy controls were evaluated for demographic/exposures data, urological evaluation, hormone profile and sperm analysis (including sperm DNA fragmentation). Clinical features, disease activity/damage scores and treatment were also evaluated.

Positive rheotaxis extended drop: a one-step procedure to select and recover sperm with mature chromatin for intracytoplasmic sperm injection.

Purpose: The purpose of this study was to develop a novel one-step ICSI approach to select sperm with better chromatin maturity than the conventional method.

Methods: This was a pilot diagnostic study, which prospectively recruited men during a 6-month period in a University-affiliated infertility centre. Forty consecutive semen samples were provided for analysis.
