...einizing hormone (LH) at puberty. The deficiency in release or action of GnRH leads to hypogonadotropic hypogonadism (HH) characterized by low FSH, LH and testosterone (T) and absent or impaired sexual development at puberty. Amongst others, mutations in GPR54 and GnRH receptor (GNRHR) are possible causes of HH. This study aimed at identification of mutations in GPR54 and GNRHR genes and their correlation with HH in Pakistan...

...gitudinal bone growth at puberty or pubertal growth spurt has been ascribed to reciprocated physiological influences of both somatotropic and gonadal axes, manifested as higher secretion of growth hormone (GH) and testosterone (T). GH and T affect linear growth velocity (LGV) directly through stimulation of chondrocytes and osteoblasts. Furthermore, T promotes LGV through augmentation of GH secretion. Nevertheless, age and developmental stage dependent changes...
