Puberty before 10?

The NYTimes has an interesting and lengthy article about little girls who are getting some secondary sexual characteristics – including pubic hair and developing breasts – very early.  They are also doing some follow up on the topic with a 3 pm EST discussion on the Time’s facebook page today.

For me the two most important claims made were:

1.  If you use this as an opportunity to engage your family with the problems located in your daughter’s body, you may well do very lasting damage.  As it is, someone out of step with her peers’ development has enough problems to worry about.

2.  What is going on in many cases may not actually involve a genuine puberty.  In fact, the age for starting menstruation is remaining fairly much the same.  One hypothesis is that it is environmental estrogens that are causing the development of second sexual characteristics.

Apparently, genuine puberty requires brain changes that trigger a lot of different responses, and in many early development cases that does not seem to have happened.  This fact is fortunate, since a genuine early puberty can have serious consequences for skeleton growth and development.

BPA has been a concern for some years, since it is mildly estrogenic.  However, on Friday, March 30, the US’s Food and Drug Administration  refused to ban the use of BPA in food containers since it said the scientific evidence for the ban is insufficient.  It is doing further testing on the issue.

  1. I had my first period at the age about 10…And my mother got really worried about it. I still remember lots of medical check-ups and plenty of different doctors including gynecologists…It was such a shocking experience for me that I’m afraid of gynecologists even now, being a young woman…I beg you not to torture your daughters, only in case of emergencies, because…Well, it’s just our payoff for the comfortable time we live in, nothing more. Our kids grow up faster than we and our peers many years ago, and we can hardly do anything to stop it, but we still can be caring mothers, and our main aim is to help our children to become older and step into an adult life as normal people…
