[Role of men in contraception, as users and partners].

Reproductive health programs have focused their attention on women; in general, they have not worked much with men. Gender is not only a determinant of inequality, but it also provides explanations for the different factors that have an impact on men and women's health, their disease and their death. This article addresses the factors that are prioritized over the information and decisions concerning the exercise of sexuality and how to regulate reproduction. With regards to the beginning of sexual life, men seem to start earlier, in average, they have their first sexual relation at 16.8 years old. As to the use of contraceptive methods, currently 54.2% of men declare to use them. Out of these, 39.5% choose modern methods whereas 14.5% prefer traditional ones. In Peru, among the modern methods available are the barrier methods (the condom being the most used), the chemical methods or spermicides, and the surgical methods (vasectomy). Among the traditional ones are the "rhythm" based on abstinence during the fertile phase of the menstrual cycle, and the coitus interruptus. The father's role is one of power. Gender relations are relations of power, and parenthood is part of these relations. The father is, above all, the provider of filiation. Marginalization of men in the reproductive process is evident. Their support to their partner is suboptimal, whether it is during pregnancy, during delivery or to prevent the death of the mother.
