Drive your car, save the planet

Doctors can do a lot of things but I do not know of any evidence that we have altered the onset of sexual maturity. In most cases if sexual maturity is delayed we can't do anything about it other than find a cause and tell the patient/family what the likely outcome is. (ie: diagnosis/prognosis but not much treatment)

If we DID know how to accelerate sexual maturity I doubt many pediatricians would want to use that knowledge for treatment of normal girls.

is partly because of the York studies. The birth and neonate-survival records correlate well with the ups and downs of crop successes.

After I read this and some of the other speculation I began to wonder...

It is documented that young girls involved with rigorous athletics (such as gymnastics) will often postpone their menarche for years after their peers have experienced them. The young athlete's bodies put it's energy into muscular development rather than sexual development.

If there is a direct correlation between fat cells and menarche then one wonders if the decreasing age of sexual maturation found in certain countries is caused by a combination of diet and physical inactivity that is increasingly found in the youth of western cultures, (especially the USA)?

I have no idea if it is correct, but it is an interesting idea.
