  • 위에서 살펴본 바와 같이 준임상적 정계정맥류이 존재가 불임 환자에서 가지는 중요성에 관하여는 아직 논란이 많다. 하지만 실제적인 정계정맥류의 크기와 신체검사에서 촉진되는 정계정맥류의 크기가 항상 일치하지는 않는다는 사실과 준임상적인 정계정맥류라 할지라도 고환에 악영향을 끼칠 수 있는 잠재력이 있음을 고려할 때, 준임상적 정계정맥류의 임상적 중요성을 결코 간과해서는 안 될 것이다. 비록 현재는 불임의 치료로서 준임상적 정계정맥류의 제거술의 잇점이 뚜렷이 규명되지는 않았지만, 불임을 주소로 내원한 환자에 있어 준임상적 정계정맥류의 존재는 항상 염두에 두어야 할 사항이라 생각된다. 또한 앞으로도 준임상적 정계정맥류의 치료 효과 및 필요성에 관하여는 잘 계획된 많은 연구들이 필요할 것으로 사료된다.

  • Objective: Human sperm nucleus DNA damage may negatively affect pregnancy outcome, and the spermatozoa of infertile men have more DNA damage than that of fertile men. The aim of this study was to evaluate the effect of microsurgical varicocelectomy on human sperm nucleus DNA integrity. Methods: We reviewed the medical records of 18 subfertile male patients who underwent microsurgical varicocelectomy at our hospital from April 2006 to April 2007. Varicocele was diagnosed by physical examination and Doppler ultrasound. Standard semen analysis was performed in 18 patients before and 4 months after microsurgical varicoceletcomy using a computer assisted semen analyzer. Sperm nucleus DNA integrity was assessed by a single-cell gel electrophoresis (comet assay). Results: No recurrence of varicocele was observed after 4 months later. The DNA fragmentation index improved after varicocelectomy compared with pre-operatively (19.3 versus 13.7%, respectively, p<0.05). Semen analysis parameters (total count, concentration, motile sperm, viability, strict morphology) increased after varicocelectomy, but the difference did not reach statistical significance. Conclusion: Our data suggest that microsurgical varicocelectomy can improve semen analysis parameters and human sperm nucleus DNA integrity in infertile men with varicocele.

  • Purpose: The purpose of this study is to determine the effect of preoperative semen parameters on both seminal improvement and pregnancy rates following varicocelectomy. Methods: This survey was done in 278 patients who underwent microsurgical inguinal varicocelectomy from January 2001 until October 2006. By the total motile sperm counts (TMSC) before operation, the patients were stratified into three groups. Group A (mild oligoasthenospermia) was defined as above 20 million, group B (moderate oligoasthenospermia) was defined as between 5 and 20 million, and group C (severe oligoasthenospermia) was defined as below 5 million. Improvement rates of TMSC and pregnancy rates following varicocelectomy of each groups were compared. Results: The average TMSC of all the patients was 25.75 million before operation and after operation, it was 80.24 million, showing an average increase of 54.49 million (211.6%). To take a look at mean absolute increase (mean relative increase proportion), group A showed 67.90 million (131.2%), group B 62.20 million (482.5%) and group C 26.33 million (1841.2%). The patients with varicocele whose semen parameter is in bad condition show relatively a low mean absolute increase but high mean relative increase proportion. There was no significant difference in natural pregnancy rate among each groups (p=0.119, p=0.059). Conclusions: Even in the varicocele patient whose semen parameter was in bad condition before surgical operation. varicocelectomy could be chosen as the first treatment to male infertility.
