[Planning of pregnancy and birth control in the capital of Valladolid (author's transl)].

This work presents the results which the authors obtained by means of an inquiry carried out on 920 women with children, or women bearing their first child, in order to find out how many pregnancies are conceived deliberately in the capital of Valladolid and what kind of birth control was adopted by the couples in this capital in order to delay, postpone or prevent pregnancy. The authors come to the conclusion that, first, during the seventies a little less than 50% of the gestations in Valladolid were not planned or wanted. The first pregnancy is not planned in one out of four cases, of which nearly 50% are women under twenty years of age. The couples seek to control their reproduction once they have their first two children. From 30 years onward, seven out of ten pregnancies are neither planned nor wanted. Three quarters of the women investigated, or their husbands, use some method of birth control, normally of little efficacy, and this because of the method itself, or because of the deficient way they use it. "Coitus interruptus", alone or combined with other methods, is practised by two of three couples who seek to control their reproduction.
