Semen Parameter Response to Varicocele Repair in Infertile Men With Cryptozoospermia

Area of Science:

• Reproductive Medicine
• Urology
• Andrology

Background:

• Varicocele is a common cause of male infertility.
• Cryptozoospermia, characterized by extremely low sperm count, presents a significant challenge for natural conception and assisted reproductive technologies.
• Semen parameter improvement after varicocele repair can enhance fertility outcomes.

Purpose of the Study:

• To evaluate the impact of varicocele repair on semen parameters in infertile men with cryptozoospermia.
• To assess the potential for varicocele repair to improve candidacy for assisted reproductive technologies like in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).
• To determine if semen parameter response post-repair influences subsequent fertility treatment decisions.

Main Methods:

• Retrospective review of electronic health records for men with palpable varicoceles and at least two consecutive semen analyses showing cryptozoospermia.
• Analysis of semen parameters before and 3-6 months after subinguinal microsurgical varicocele repair.
• Statistical analysis to identify correlations between patient demographics (age, FSH) and varicocele grade with semen parameter improvement.

Main Results:

• 54% of men with preoperative cryptozoospermia demonstrated improved semen parameters post-varicocele repair, ranging from severely oligozoospermic to normozoospermic.
• No statistically significant association was found between patient age, follicle-stimulating hormone (FSH) levels, or clinical varicocele grade and the degree of semen parameter improvement.
• Improvement in semen parameters post-repair optimized fertility treatment options, potentially obviating the need for surgical sperm retrieval.

Conclusions:

• Varicocele repair can significantly improve semen parameters in infertile men with cryptozoospermia.
• The procedure enhances the likelihood of successful IVF/ICSI or less invasive fertility treatments.
• Varicocele repair is a viable option for infertile men with palpable varicoceles and cryptozoospermia, irrespective of age, FSH, or varicocele grade.
