Insights
Varicocele surgery improves sperm parameters, but vein size doesn't predict success. Lower body mass index (BMI) is linked to better sperm motility recovery after varicocelectomy.
Area of Science:
- Reproductive Medicine
- Urology
- Andrology
Background:
- Varicocele, enlarged veins in the scrotum, is a leading cause of male infertility.
- Surgical correction (varicocelectomy) aims to improve semen parameters.
- The impact of varicocele vein diameter and patient BMI on post-surgical outcomes requires further investigation.
Purpose of the Study:
- To examine the correlation between preoperative varicose vein diameter and spermogram improvement after varicocelectomy.
- To assess the influence of body mass index (BMI) on sperm parameters post-varicocelectomy.
Main Methods:
- A descriptive, analytical, cross-sectional study of 27 men with unilateral left varicocele.
- Data collected included demographic information, varicose vein diameter, and spermogram results before and 3 months after varicocelectomy.
- Statistical analysis was performed using SPSS version 21.
Main Results:
- Varicose vein diameter before surgery showed no significant association with improvements in major semen parameters.
- A lower body mass index (BMI) was associated with a greater improvement in sperm motility after varicocelectomy.
- Patients with lower BMI demonstrated more significant gains in sperm motility.
Conclusions:
- Varicocele vein diameter is not a predictor of spermogram recovery after varicocelectomy.
- Lower BMI may positively influence sperm motility improvement following varicocele repair.
- Further research is warranted to elucidate the role of BMI in male fertility outcomes post-surgery.
Introduction:
Varicocele is a condition in which the veins in the spermatic cord become enlarged and twisted. Varicocele is widely recognized as the leading cause of male infertility due to its significant impact on reproductive health in men. The aim of this study was to investigate the relationship between the diameter of the varicose vein and the recovery rate of the spermogram after varicocelectomy. Also, the effect of body mass index (BMI) on sperm parameters after varicocelectomy.
Methods:
This descriptive and analytical cross-sectional study was conducted in Valiasr Hospital's urology clinic in Qaemshahr, Iran from August 2018 to August 2019 and involved 27 men with unilateral left varicocele who met the inclusion criteria for surgical repair. Before the operation, we recorded demographic information, the maximum diameter of varicose veins in the pampiniform plexus, and spermogram results. We repeated semen analysis 3 months after the operation and analyzed the data using Statistical Package for the Social Sciences version 21 software.
Results:
Our findings showed that the diameter of the varicose vein before varicocelectomy was not significantly associated with the improvement of main semen parameters after the operation. Furthermore, our study suggested that a lower body mass index might contribute to a greater improvement in sperm motility, as individuals with lower BMI showed more significant improvement.
Discussion:
There is a significant inverse relationship between BMI and sperm motility improvement after surgery. Patients with a lower BMI showed greater improvement in sperm motility.
