Fig. 4

The cumulative rate of sexual intercourse, marriage, and paternity. a and b The cumulative rate of sexual intercourse and marriage is shown, stratified as having been reoperated for obstructive complication (Study group) or others (Study controls), together with national survey data (General population, plotted by X). a No statistical difference was noted in the intercourse rate (p = 0.76) between the Study group and Study controls. There was no significant difference with the General population either. b The marriage rate of the Study group at 32.5 years old was significantly lower than that of the General population (†: p = 0.048, z-test). At 27.5 years old, the marriage rate of the General population and Study group was radically different, 36.7% vs. 0%, although p-values of the z-test could not be calculated because there was no event in the Study group before these time points. P-value for the difference in the marriage rate between the Study group and Study controls was not statistically significant in the log-rank test (p = 0.13). c and d No paternity was observed in patients reoperated for obstruction. Paternity rates were significantly lower in patients reoperated for obstruction in analysis of total patients (c, p = 0.032 by log-rank test) and in analysis of married patients (d, p = 0.012 by log-rank test)
