If melatonin is anti-gonadal, that is, it delays sexual maturity, then shouldn’t it delay sexual maturity in congenitally blind girls rather than helping them attain sexual maturity at an early age?
melatonin released from pineal gland and and its one of the function is that it delays sexual maturity. but there are also a point to remember that pineal gland is activated at that time when light stimulate the retina but in the case of blind person activation of pineal gland is not occurs. that's why hr. like melatonin is not secreted and sexual maturity come before time. it come 2-4 years before the normal age.
