Hypogonadotropic hypogonadism is characterized by insufficient gonadotropin production, resulting in low testosterone levels and impaired spermatogenesis. Unlike primary testicular failure, this condition originates from hypothalamic or pituitary dysfunction.
Congenital causes include Kallmann syndrome, whereas acquired causes may involve pituitary tumors, head trauma, systemic disease, or chronic opioid use.
Symptoms include delayed puberty, reduced facial and body hair, infertility, decreased libido, and fatigue. Diagnosis is established through hormonal evaluation demonstrating low testosterone with low or inappropriately normal LH and FSH.
Treatment strategies focus on hormone replacement or gonadotropin therapy. In men desiring fertility, human chorionic gonadotropin (hCG) combined with FSH therapy stimulates spermatogenesis.
Multidisciplinary management ensures optimal hormonal erotic restoration and reproductive potential.
