The extent of men's roles in reproductive decision-making in Africa is
a subject of contention. Despite the volume of work on the roles men
play in fertility decisions, there have been few attempts to derive di
rect empirical estimates of the effect of men's preferences on reprodu
ctive behavior. I employ 1989 and 1993 Kenya Demographic and Health Su
rveys to examine the relative roles of the reproductive preferences of
males and females on contraceptive use. Additive and interactive meas
ures of preferences document a significant effect of men's preferences
, which may eclipse women's preferences. The implications of these fin
dings are discussed.
