Biología de la capacitación espermática: un proceso in vivo

Autores

Jorge Alberto Salazar-Cartín

RESUMEN

La capacitación espermática es un proceso biológico que ocurre de forma natural entre el epidídimo del varón hasta el óvulo de la mujer. A lo largo de este recorrido los espermatozoides son objeto de grandes modificaciones. Estas modificaciones son necesarias para que el espermatozoide adquiera la capacidad de desencadenar una reacción acrosomal y proseguir con la fecundación del óvulo. En la presente revisión se acompaña a los espermatozoides en este recorrido y se revisan los distintos aportes que realizan los órganos sexuales tanto masculinos como femeninos sobre ellos, así como la interacción entre los fluidos de la pareja que se complementan en este íntimo proceso.

ABSTRACT

Sperm capacitation is a biological process that occurs naturally in the journey from the male epididymis until it reaches a woman’s egg. Throughout this journey the sperm suffers abundant modifications which are  necessary in order to acquire the ability to trigger an acrosome reaction and to continue with the ovule’s fertilization. In the present work, we deeply reviewed the sperm’s capacitation journey, the different contributions made by the male or female sexual organs, and any cooperative activity of each partner’s fluids that might complement each other in this intimate process.
