Plain-language summary

Men with idiopathic hypogonadotropic hypogonadism (IHH, Kallmann Syndrome) may have small testicular size, low testosterone levels, no history of puberty, and infertility. These men lack a hormone called gonadotropin releasing hormone (GnRH) that stimulates the development and maturation of the testes. This study will investigate the impact of hormonal treatments on men with IHH. The goal of hormonal therapy is to maximize the potential fertility in these individuals.
