Vahidi s, et al. - Authors assessed the effects of microsurgical varicocelectomy on semen analysis and sperm functional tests in men with different grades of varicocele. They noted a significant positive effect of not only M-varicocelectomy on semen quality but also if sperm functional tests become more affordable in the future as they give more precise results, their use in daily practice may increase significantly in patients with varicocele. Nonetheless, on a separate analysis, the surgery caused improvements in semen quality but may have more statistically significant effects on patients with varicocele of higher grade.
