Research in animal reproduction: An analysis of the contribution made by Latin America

In an analysis carried out on the proceedings of the last two international congresses on animal reproduction and artificial insemination (1980 and 1984), a total of 944 papers presented were classified according to sex and species of the experimental animal, reproductive event studied, and country of origin. Latin America was found to be responsible for almost 10% of presentations, with Venezuela and Mexico making up half that total. The bovine species was the most studied both by Latin American countries (51.1%) and in general (42.7%). Approximately 15% of the Latin American contribution was concerned with goat studies versus 3.4% in general. Overall, the female was studied twice as much as the male. Fertility and estrous cycle were the reproductive events most studied both in general (36.3% and 31.6%, respectively) and by Latin American authors (27.2% and 33.3%, respectively). Latin American research concentrated on two main aspects: the effect of environment on reproduction and reproductive efficiency (25.8% and 13.7% of the total, respectively).
