    Effect of varicocele surgery on sperm quality

    Chaudhari Tejas Chandrakant and Rajiv Nandan Sahai*

    Introduction: A varicocele is a vascular lesion characterised by dilatation and tortuosity of the veins of the pampiniform plexus and is found in approximately one-fifth of the adult male population. It is the most common cause of treatable infertility. 

    Physical examination may or may not show a varicocele which is mostly diagnosed only when patients present with infertility or adolescents during a physical examination, like testicular hypotrophy, impairment in spermatogenesis mainly in the form of low or absent count, decreased sperm motility, and abnormal sperm morphology. 

    Treatment for varicocele includes medical therapies, radiological embolization, and surgical techniques. Medical therapy, including antioxidants and anti-inflammatory agents, has been utilized with variable success. Radiological embolization of varicocele is a new technique in the treatment of varicocele, but it is associated with high recurrences and high cost. Varicoceles are surgically treated either by open or laparoscopic approaches the principal aim being occlusion of the dilated veins of the pampiniform plexus. 

    A definitive conclusion of indication of medical treatment cannot be drawn at present because most published studies have inadequate design and lack controls. 

    Various studies in the past have concluded significant changes in sperm parameters (total count, motility, morphology) post-varicocele repair. However, few other studies suggest no improvement in sperm parameters following surgical varicocele repair and studies that conclude recommendations against repair of varicocele. Thus, conflicting opinions have opened the scope to establish this fact by this study. 

    Aim: To evaluate changes in sperm morphology, sperm count, and sperm motility in a patient with varicocele after varicocele surgery. 

    Materials and methods: The study was conducted in the Department of Surgery, North Delhi Municipal Corporation Medical College & Hindu Rao Hospital, Delhi, India from August 2019 to February 2021. The sample size was calculated to be 50 using Slovin’s formula with a confidence level of 95% with a margin error taken as 5% (p - value 0.05). 

    Sperm morphology, sperm count, and sperm motility were the parameters studied before and after 3 months of surgery. 

    Results: The majority of patients belonged to the age group of 18 to 25 years (42%) followed by 26 to 35 years (40%) (27.78 ± 6.547 years). Left-sided varicocele was more common (54%), followed by bilateral varicocele (42%). Varicocele grade II was most common (58%) followed by grade I (30%) and lastly grade III (12%). Total sperm count improved by 8.88 million per ml after varicocelectomy. Total sperm motility improved by 6.08% after the surgery. Total normal sperm forms improved by 6.44% after varicocele repair. 

    Conclusion: Based on the findings it was concluded that Varicocelectomy results in significant improvement in total sperm count, total sperm motility, and total normal sperm morphology. The best improvement was seen in sperm count followed by total normal sperm forms and lastly total sperm motility.
