Varicocele - Overview

Nombres alternativos

Venas varicosas en el escroto

Definición:

Es una dilatación de las venas a lo largo del cordón que sostiene los testículos de un hombre.

Causas:

El varicocele se forma cuando las válvulas dentro de las venas que hay a lo largo del cordón espermático impiden que la sangre fluya apropiadamente. Esto hace que la sangre se represe, llevando a una hinchazón y dilatación de dichas venas. (Se trata esencialmente del mismo proceso que lleva a la formación de las venas varicosas, que son comunes en las piernas).

Los varicoceles en general se desarrollan lentamente. Son más comunes en hombres entre 15 y 25 años de edad y se observan con más frecuencia en el lado izquierdo del escroto. Los varicoceles a menudo son la causa de infertilidad en los hombres.

La súbita aparición de un varicocele en un hombre mayor puede ser causada por un tumor renal que puede bloquear el flujo sanguíneo a una vena. Esto es más común en el lado izquierdo que en el lado derecho.
