OMIM	176410

Familial male-limited precocious puberty, often abbreviated as FMPP, also known as familial sexual precocity or gonadotropin-independent testotoxicosis,^[1] is a form of gonadotropin-independent precocious puberty in which boys experience early onset and progression of puberty.^[2] Signs of puberty can develop as early as an age of 1 year.

The spinal length in boys may be short due to a rapid advance in epiphyseal maturation. It is an autosomal dominant^[1] condition with a mutation of the luteinizing hormone (LH) receptor. Treatment is with drugs that suppress gonadal steroidogenesis, such as cyproterone acetate, ketoconazole, spironolactone, and testolactone.^[3] Alternatively, the combination of the androgen receptor antagonist bicalutamide and the aromatase inhibitor anastrozole may be used.^[4]

Male-limited precocious puberty has an autosomal dominant pattern of inheritance.
