Objective:

Vasovasostomy is the most common surgery to restore the fertility of vasectomized men. This study aimed to compare the outcomes of one-layer macroscopic VV (MOLVV) or two-layer microscopic VV (TLMVV)

Methods:

This study was performed on the medical records of 100 patients who underwent VV surgery in two tertiary hospitals from 2014 to 2017. All patient information, including demographic and sperm analysis, was collected. The chi-square test, independent t-test, and survival analysis using Kaplan–Meyer test and Cox regression were performed to analyze the data using SPSS software version 25, and the significance level was considered 0.05.

Results:

The fertility rate in patients of both groups was 15%. The findings showed a statistically significant difference between the mean percentage of normal sperm morphology according to the type of surgery (p = 0.045). There was no statistically significant difference between the mean sperm count, sperm motility percentage, and mean hospital costs according to the type of surgical procedure (p > 0.05). The incidence of spouse pregnancy in the TLMVV method after 15 and 24 months was 87.5% and 58.3%, respectively. In patients with unilateral anastomosis, the incidence of pregnancy at 13 and 15 months after surgery was 98.7% and 95.8%, respectively. The mean and median time of pregnancy in the spouses of patients with each surgical shower were 24 and 25 months. Other variables had no significant effect on spouse pregnancy.

Conclusion:

Vasovasostomy with the one and two-layer methods had equal results. The number, movement, and normal morphology of sperm after surgery were low. Therefore, these people will need assisted reproductive techniques.
