The main outcome is the identification of novel GnRH secretory patterns or non-reproductive phenotypic characteristics in individuals representing the complete spectrum of idiophatic hypogonadotropic hypogonadism.
Secondary outcomes are the recognition of specific pubertal phenotypes, as well as discovery of the roles of newly identified genes contributing to IHH in GnRH development and biology, for those subjects who also enroll in our genetics protocol.
