Article Synopsis
- - Varicocele can harm male fertility by increasing oxidative stress, which leads to excess reactive oxygen species that damage sperm and its DNA.
- - Sperm DNA fragmentation, often seen in men with varicocele, is a result of this oxidative stress and is linked to fertility problems.
- - The paper discusses the relationship between varicocele, oxidative stress, and sperm DNA damage, focusing on how repairing varicocele might improve fertility and suggesting further research areas for better clinical understanding.
Ejaculatory duct obstruction is a rare condition identified in up to 5% of infertile men. Patients with ejaculatory duct obstruction can present with aspermia, azoospermia or oligoasthenospermia, painful ejaculation, hematospermia, prostatic pain, or male infertility. Semen analysis, transrectal ultrasonography, pelvic computerized tomography and magnetic resonance imaging are often used in the diagnostic work up, but with limited accuracy.
