Hypogonadotropic Hypogonadism

A condition characterized by inadequate gonadal function due to deficient gonadotropin (LH/FSH) secretion from the pituitary, resulting in low sex hormone levels, infertility, and delayed puberty.

Quick Answer

Detailed Outcomes

A
Diagnostic Accuracy
GnRH stimulation test evaluates HPG axis. Measures LH/FSH response to bolus. Cannot distinguish CDP from IHH prepubertally, but useful post-pubertally.
moderate↑Improves
A
Spermatogenesis Induction
Pulsatile GnRH achieves spermatogenesis in 85% (58/68) of HH males. Median time 6 months with pump vs 14 months with gonadotropin therapy (p=0.01).
large↑Improves
A
Testicular Growth
100% of HH males treated with pulsatile GnRH achieve testicular growth and virilization. Physiological approach preserving fertility.
large↑Improves
A
Puberty Induction
Pulsatile GnRH induces physiological puberty in HH. Advantages over testosterone: stimulates testicular growth and fertility while achieving virilization.
