I'm can't fine the full known scope of reasons of male normogonadotropic hypogonadism.
From this article I see the two basic reasons:
- Gonadal dysgenesis variants (residually functioning ovarian tissue)
- Hyperprolactinemia Also there obesity can be the reason.
But are there any other reasons? For example, what if the patient is young, thin with normal prolactin and with testicles responding to hCG therapy?
