Etiología y Fisiopatología

Para lograr el embarazo, la mujer debe estar ovulando con trompas de Falopio permeables y un útero receptivo, mientras que el hombre debe producir esperma que sea capaz de fertilizar el ovocito.

  • Etiología masculina aislada: 8%
  • Tanto etiologías femeninas como masculinas: 35%
  • Infertilidad inexplicable: 5%
  • Las etiologías exactas a menudo son difíciles de determinar a menos que estén presentes factores absolutos de infertilidad (e.g., obstrucción tubárica bilateral).
  • Las parejas a menudo tienen más de una etiología contribuyente.
