Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism, is a condition which is characterized by hypogonadism due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production and elevated gonadotropin levels (as an attempt of compensation by the body). HH may present as either congenital or acquired, but the majority of cases are of the former nature.[1][2]

There are a multitude of different etiologies of HH. Congenital causes include the following:[1][3][4]

Acquired causes (due to damage to or dysfunction of the gonads) include gonadal torsion, vanishing/anorchia, orchitis, premature ovarian failure, ovarian resistance syndrome, trauma, surgery, autoimmunity, chemotherapy, radiation, infections (e.g., sexually-transmitted diseases), toxins (e.g., endocrine disruptors), and drugs (e.g., antiandrogens, opioids, alcohol).[1][3][4]

Examples of symptoms of hypogonadism include delayed, reduced, or absent puberty, low libido, and infertility.

Treatment of HH is usually with hormone replacement therapy, consisting of androgen and estrogen administration in males and females, respectively.[3]
