Case Report

A few studies described human causes with congenital leptin deficiency with early onset of hypogonadiwm, hyperphagia, hypogonadotropic hypogonadism, and delayed puberty. In the presence of leptin resistance, due to obesity, leptin is supposed to be unable to stimulate GnRH secretion, with consequent low levels of FSH and LH and hypogonadism [ 6768 ]. Hypogonadotropic hypogonadism HH is a form of hypogonadism that is due to a problem with the pituitary gland or hypothalamus.

In central hypogonadism, the centers in the brain that control the gonads hypothalamus and pituitary do not function properly.

Onset of puberty is characterized by pulsatile GnRH release from the hypothalamus that stimulates pituitary LH secretion, which, in turn, drives testosterone production by testicular Leydig cells [ 45 ].

On the basis of recent findings, human Leptin is supposed to be implicated in the secretion of GnRH through stimulation of several hypothalamic neurons, secreting neuropeptide Y, proopiomelanocortin, and kisspeptin 1 [ 6768 ]. Metay, J.

Although widely used, the practical value of the GnRH test has been questionable because of its low cost-effectiveness. PROKR1 is mainly expressed in peripheral tissues, hypogomadism endocrine glands whereas PROKR2 shows relatively localized distribution in the central nervous system, in particular in the subventricular zone SVZ and in the olfactory bulbs [ 46 ]. If the hypothalamus or the pituitary is injured for any reason. In Kallmann syndrome, anosmia is related to hypoplasia or aplasia of the olfactory bulbs, whereas the hypogonadism is due to GnRH deficiency, due to defective migration of olfactory and GnRH neurons.
