Does varicocelectomy affect DNA fragmentation in infertile patients?

Area of Science:

• Reproductive Medicine
• Andrology
• Urology

Background:

• Varicocele is a common cause of male infertility.
• It is associated with impaired semen quality and increased sperm DNA damage.
• Surgical repair (varicocelectomy) is a potential treatment option.

Purpose of the Study:

• To evaluate the impact of varicocelectomy on sperm DNA fragmentation index (DFI).
• To assess changes in semen parameters following varicocele repair.

Main Methods:

• Prospective study of 72 infertile men with varicocele and oligospermia.
• Semen samples analyzed pre- and post-varicocelectomy.
• Acridine orange test used to measure DFI; WHO guidelines for semen analysis.

Main Results:

• DFI significantly decreased from 34.5% to 28.2% post-surgery (P=0.024).
• Sperm count, concentration, progressive motility, and morphology showed significant improvements (P<0.001).
• Limitations include patient follow-up and unrecorded pregnancy outcomes.

Conclusions:

• Varicocele contributes to sperm DNA damage.
• Varicocelectomy demonstrates efficacy in improving semen parameters and reducing DFI in infertile men.
