Delayed puberty is defined as absent testicular enlargement in boys or breast development in girls at an age that is 2 to 2.5 SDS later than the mean age at which these events occur in the population (traditionally, 14 years in boys and 13 years in girls).

Clinical Management of Congenital Hypogonadotropic Hypogonadism
Endocrine Reviews, 2019 The initiation and maintenance of reproductive capacity in humans is dependent on pulsatile secretion of the hypothalamic hormone GnRH. Congenital hypogonadotropic hypogonadism (CHH) is a rare disorder that results from the failure of the normal episodic

We aimed to analyse FGFR1 rare variants in a series of Chinese congenital hypogonadotropic hypogonadism (CHH) patients. In addition, we intended to understand the clinical characteristics and the response to treatment of CHH patients with FGFR1 rare ...

This article outlines the changing pattern of gonadotropin-releasing hormone (GnRH)-induced gonadotropin secretion across sexual development, a knowledge of which is critical to understanding GnRH secretion in pathologic states such as hypogonadotropic hypogonadism.

Hypogonadotropic hypogonadism is characterized by failure of gonadal function secondary to deficient gonadotropin secretion, resulting from either a pituitary or hypothalamic defect, and is commonly seen in association with structural lesions or functional defects affecting this region.

Male Hypogonadotropic Hypogonadism
Endocrinology and Metabolism Clinics of North America, 1993Hypogonadotropic hypogonadism in the male is caused by alterations in gonadotropin-releasing hormone secretion or through abnormal pituitary secretion of luteinizing hormone or follicle-stimulating hormone. Recent studies in animal and human models have demonstrated possible pathophysiologic explanations for the occurrence of some GnRH-deficient states.

Gonadotropin-releasing hormone (GnRH) and olfactory neurons migrate together from the olfactory placode, and GnRH neurons eventually reside in the hypothalamus. Hypogonadism in male infants may be diagnosed in the first 6 months of life but cannot be diagnosed during childhood until puberty occurs.

Genetics of Hypogonadotropic Hypogonadism
2015Hypogonadotropic hypogonadism (HH) often manifests as pubertal delay. A considerable proportion of cases of HH is due to genetic mutations. Recognizing those mutated genes and associated phenotypes may improve our diagnostic capabilities. GNRHR and TACR3 should be the first two genes to be screened in a clinical setting for equivocal cases such as ...
