Reproduction, basis of sexual differences (Peru)
Anatomical and physiological differences between men and women develop during the life cycle and reflect their role in reproduction. Primary sexual characteristics differentiate early in the foetal stage (external and internal sexual organs), while complete functionality of the sexual organs and the appearance of secondary sexual characteristics and adult behaviours are established in adolescence.
Biological processes, including reproduction, have remained constant for the 200,000 years that our species has existed, which contrasts with the extraordinary change in environmental determinants linked to culture, which define sexual, reproductive, social and productive behaviour, as well as the autonomy to decide about them. Cultural factors, with which they interact, modulate differential access by age, gender, population and country and the expenditure and distribution of nutritional energy, labour demands and healthcare and the family.
