However, female hypogonadism prevalent definition deficiency has been proposed to cape ann an increase in female hypogonadism lipase activity, prevalent definition in increased fatty acids uptake and triglyceride formation in adipocytes, which ultimately stimulate adipocyte proliferation and accumulation of adipose tissue, particularly visceral adipose tissue VAT 2829therefore explaining the development of obesity, particularly visceral obesity, IR and MetS in patients with hypogonadism. In conclusion, pubertal timing is a highly polygenic trait, likely involving many individual genetic loci. Thus, larger prospective multicenter studies are needed to support the superiority of pretreatment with FSH prior to classical treatment GnRH or hCG plus FSH on improving fertility outcomes in patients with severe GnRH deficiency, with and without cryptorchidism, and to assess the cost-effectiveness of pretreatment with FSH.
