Data from the 1991 National Survey of Men indicate that about 12% of m
arried men aged 20-39 have had a vasectomy and about 13% are married t
o a woman who is sterilized. Multivariate analyses indicate that the l
ikelihood of sterilization rises with husband's age, wife's age, durat
ion of marriage and number of children. Black couples are significantl
y less likely than white couples to rely on sterilization, and interra
cial couples are less likely than same-race couples to be sterilized.
The likelihood of reliance on vasectomy rather than tubal ligation als
o rises with husband's age, while black men are significantly less lik
ely than white men to elect male over female sterilization. Use of mal
e sterilization is strongly associated with having had a recent contra
ceptive failure while using a male method.
