Introduction to anatomy and physiology of human conception

Anatomical and physiological concepts of human reproduction currently in use have been developed over generations, following clinical and basic research guidelines that preceded modern technology. The application of new forms of research over recent decades, as in the case of molecular biology, has contributed to a more in-depth and accurate understanding of the interaction of each of the inter- and intracellular structures in the mechanics of human physiology. On the other hand the use of non-human primate models has provided invaluable information in the reproductive field. The information obtained through models and techniques that have changed over time has led to concepts that continue to have the same validity as when they were first described. The principal objective of this review is to develop an understanding of the physiological processes applied in the anatomical sphere, taking as a reference the fact that it is impossible to understand reproductive mechanics in terms of static phenomena, but rather they should be understood as dynamic and changing processes adaptable to the conditions of each individual's surroundings.
