Vasectomy in Men without Children: Demographics and Family Planning Attitudes from the National Survey for Family Growth.

Introduction: To investigate the ethically challenging scenario of a childless man requesting a vasectomy, we compared vasectomy reversal rates and family planning attitudes in men who underwent vasectomy with and without fathering a child.

Methods: We performed an analysis of the 2002 to 2006, 2006 to 2010, 2011 to 2013, 2013 to 2015 and 2015 to 2017 waves of the National Survey for Family Growth, a nationally representative survey of family planning in the United States. We compared demographic information and family planning attitudes among men who had undergone vasectomy with and without having children.

Results: Of the 29,192 men surveyed 1,043 (3.6%) reported undergoing a vasectomy. Of the men reporting vasectomy, 4.4% (95% CI 3.2-6.0) underwent the procedure without having had children. Compared to men with children, men without children were less likely to have ever been married and were more likely to not identify with any religion. Whereas 1.2% (95% CI 0.5-2.4) of men with children underwent vasectomy reversal during the followup, 0% of men without children underwent reversal.

Conclusions: Men who undergo vasectomy without having children constitute a small but distinct population of men. During 7-year followup after vasectomy, men who have not fathered children do not express higher rates of postvasectomy regret.
