Resumen del eje hipotálamo-hipófisis-ovario

Resumen del eje hipotálamo–hipófisis–ovario:
El hipotálamo secreta la hormona liberadora de gonadotropinas, que estimula a la hipófisis anterior para que libere las hormonas gonadotropinas foliculoestimulante (FSH) y luteinizante (LH). A continuación, las gonadotropinas estimulan al ovario para que produzca estrógenos y progesterona, que a su vez provocan el crecimiento y la maduración del endometrio. Cualquier alteración en esta vía podría conducir a la amenorrea.

Patogénesis del hipogonadismo primario frente al secundario

Patogénesis del hipogonadismo primario frente al secundario:
El hipogonadismo primario es el resultado de un problema en los testículos (o en los ovarios), que provoca una disminución de la producción de hormonas sexuales a pesar de los niveles adecuados (o elevados) de la hormona liberadora de gonadotropina, la hormona luteinizante (LH) y la hormona foliculoestimulante (FSH).
En el hipogonadismo secundario, un problema en el hipotálamo o la hipófisis provoca una disminución de la hormona liberadora de gonadotropina, la LH y la FSH, lo que da lugar a una menor producción de hormonas sexuales (a pesar de que los testículos o los ovarios sean normales).
