Background: There is an emerging evidence that the ovary may be an important site where genes such as LIN28b, whose polymorphisms has been strongly associated to age at menarche, could modulate the timing of puberty. Recent data suggest that the endocannabinoid system plays a role in folliculogenesis and ovulation, through cannabinoid receptor 2 (CB2) expressed in the ovary. On the other hand childhood obesity is associated with increased likelihood of early menarche,...
