Hi folks, sorry I'm not brave enough to read through the entire 16 pages of this thread so could be repeating something others have said.
Trying to control young women's fertility rather than tackle wider issues, including businesses trying to force an ever younger population to buy stuff they don't need through adverts that promote sexually explicit behaviour, is certainly wrong and short-termist.
As others have said, the pill won't stop the spread of STIs. In fact, more girls going on the pill will probably result in more STIs.
Furthermore, tampering with a system that regulates the work of your entire body (and that's essentially what hormones do) can be dangerous in adults, no mind pubescent girls whose reproductive system is not well formed yet. I haven't seen much robust research into the way early (and particularly long-term) use of the pill affects women's fertility in the long run. If anyone has, please point me to it.
There is no ONE pill, there are many different pills based on different synthetic hormones, each of those has a very different effect. The pill MUST be carefully selected to match the hormonal levels of every individual woman. Its use MUST then be monitored to make sure that it's not causing more harm than good, and if it is, alternatives must be tried or the pill route abandoned. This is the job for a doctor, not a pharmacist. However, most GPs don't really bother with that. So an adult woman who's getting headaches, high blood pressure, spots, eczema, sporadic bleeding, or any other side effects would probably go to her GP and ask for an alternative, or just stop taking the pill. What would a young girl do, who got it without any medical supervision in the first place? Anyone's guess.
And what if she misses a pill or two? She could still get pregnant. And may not know she is until it's too late. And then may have to have a traumatic termination anyway, due to the effects of the pill on the foetus.
A better way to limit unwanted pregnancies in young girls is a range of CONFIDENTIAL services, including councelling, sexual health clinics, free condoms (dispensers in schools, clubs, etc), perhaps outright propaganda of those services that are already available.
There definately has to be some peer support, like teenage mums and dads, or girls and lads who've contracted STIs, had to go through termonations, etc. and who are ready to talk about it doing talks at schools, youth clubs, etc. EVERY schools should endeavour to get someone like that in to talk to their students, every year. But of course
