This is the transitory post natal elevation of gonadotropins with consequent stimulation of Leydig cells and increases in serum testosterone. Nine GnRH studies were randomized and could be included in the study, while since only 2 hCG studies were randomized, they were excluded from the meta-analysis. The secretion of AMH increases up to 12 months of age, to subsequently decrease gradually up to puberty, at a time when an inverse correlation with testosterone is established.
It has been described that the descent down the inguinal canal is rapid and it is completed around the 28th week. The technique is effective, safe, with low risk of complications, reproducible and with better aesthetic results, allowing correction simultaneous of associated inguinal pathologist.
