Insuficiencia testicular - Symptom

Nombres alternativos

Hipogonadismo primario en hombres

Síntomas:

  • Disminución en estatura
  • Agrandamiento de las mamas (ginecomastia)
  • Esterilidad
  • Falta de masa muscular
  • Ausencia de impulso sexual (libido)
  • Pérdida del vello axilar y púbico
  • Retraso en el desarrollo o falta de características sexuales masculinas secundarias (crecimiento del vello, agrandamiento del escroto, agrandamiento del pene, cambios en la voz)

Los hombres también pueden notar que no necesitan afeitarse con tanta frecuencia.

Pruebas y exámenes:

Un examen físico puede revelar:

  • Genitales que no lucen claramente como masculinos o femeninos (generalmente encontrados durante la lactancia).
  • Testículos anormalmente pequeños.
  • Tumor o masa (grupo de células) en o cerca del testículo.

Otros exámenes pueden mostrar baja densidad mineral ósea y fracturas. Los exámenes de sangre pueden revelar niveles bajos de testosterona y niveles altos de prolactina, hormona foliculoestimulante y hormona luteinizante.

La insuficiencia testicular y los niveles bajos de testosterona pueden ser difíciles de diagnosticar en hombres mayores, dado que estos niveles normalmente disminuyen con la edad.
