Ghrelin receptor GHSR1α is expressed in hypothalamo–pituitary–gonadal tissues. Ghrelin reduces GnRH secretion in pre-pubertal period and concentrations of ghrelin are positively correlated with testosterone at adulthood. Nevertheless, the role of ghrelin in affecting pituitary and gonadal functions during normal pubertal development remains elusive. A possible correlation between ghrelin and LH, FSH, testosterone and inhibin B was examined in boys (n=55...

The G protein coupled receptor of obestatin GPR39 is expressed in pituitary and gonads, indicating its possible role in regulation of pituitary and testicular function. The present study examined a possible association of obestatin with LH, FSH, testosterone, and inhibin B at puberty. Blood samples were collected from 10 to 20 years old boys (n=557) and concentrations of obestatin, LH, FSH, testosterone, and inhibib B were determined using specific ELISA. Data were an...
