Furthermore, other markers such as INSL3, dehydroepiandrosterone sulfate, and IGF-1 do not improve accuracy for differential diagnosis.

The latter provides a more detailed assessment of bone microarchitecture at peripheral sites e. Clinical presentation of HH depends on the time of onset ie, congenital vs acquiredthe severity of the hypogonadotropic hypogonadism therapy management, and the presence of associated conditions. However, GnRH usage is restricted to specialized tertiary hospitals and has a high cost, in addition to interfering with the patient's everyday life 45. GnRH is a decapeptide that is synthesized by a loose network of neurons located in the medial basal hypothalamus MBH and the arcuate nucleus of the hypothalamus. 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.
