Summary
Varicocele treatment via high ligation of the spermatic vein improved sperm count and morphology in infertile men. Pregnancy rates were similar between operated and non-operated groups over time.
Area of Science:
- Urology
- Reproductive Medicine
- Andrology
Background:
- Varicocele is a common cause of male infertility.
- High ligation of the spermatic vein is a surgical treatment for varicocele.
Purpose of the Study:
- To evaluate the efficacy of high ligation of the spermatic vein in infertile men with varicocele.
- To compare pregnancy rates between operated and non-operated groups.
Main Methods:
- 257 infertile men with varicocele were examined using Doppler sonography, telethermography, and palpation.
- 89 patients underwent high ligation of the spermatic vein.
- Sperm analysis and infertility history were assessed.
- Pregnancy rates were monitored over a 6-year follow-up.
Main Results:
- Postoperative sperm examination showed significant improvement in sperm count and morphology, but not motility.
- Germ cell concentration decreased significantly post-surgery.
- Pregnancy rates were 42% in the operated group and 45% in the non-operated group.
- Pregnancies occurred earlier in the non-operated group.
Conclusions:
- High ligation of the spermatic vein improves certain semen parameters in infertile men with varicocele.
- Pregnancy rates are comparable between operated and non-operated groups in the long term.
- Non-operative management can lead to relatively high pregnancy rates in varicocele patients.
