Gonadotropin-Releasing Hormone Agonist Analog (Tripotorelin) Stimulation Test in Evaluation of Pituitary -Testicular Function in Boys

Lin Xiuzhi , Ma Huamei , Li Yanhong , Du Minlian , Chen Hongshan , Chen Qiuli , Zhang Jun

Background: The hypothalamus-pituitary-gonad (HPG) axis is crutial to the development and function of reproductive system. Gonadotropin-releasing hormone (GnRH) has been the standard test for the assessment of activation of HPG axis. Because GnRH is no longer available, GnRH analogues (GnRHa) are now used. In previous studies, GnRHa stimulation tests have been the mainstay for establishing the diagnosis of precocious puberty in female and distinguishing constitutional delay of...

Background: Mandibular hypoplasia, deafness, progeroid features, and lipodystrophy (MDPL) syndrome is a genetic disorder which was first recognized in 2010. MDPL syndrome is comprised of mandibular hypoplasia, deafness, progeroid features, lipodystrophy, hypogonadism and metabolic disorders. It is caused by an autosomal dominant mutation in the polymerase delta 1 (POLD1) gene, with <30 genetically confirmed cases to date.Cas...
