AAPA symposium on Evolution through the Life Course: Why we shouldn't prescribe hormonal contraception to twelve year olds. Can the benefits of hormonal contraceptives seen in adult women be applied to girls as young as 11-12? Can the use of hormonal contraceptives influence the development of the hypothalamic-pituitary-gonadal endocrine pathways in pubescent girls? Oral contraceptives are often marketed as period regulators, especially to young girls who are more likely to experience irregular periods. However, period irregularity after menarche is due to the maturation process of the negative-feedback arc that regulates the endocrine pathway, and the effects of flooding this developing system with exogenous hormones aren't well understood.

If you're not familiar, there's an oft-cited study on college-age women that claims that women who don't use condoms are less depressed than women who use condoms or are abstinent. The authors took this to mean that there are magical happy juices in semen that is absorbed through the vaginal wall and boosts women's mood. However, there are problems with this study that people often fail to address when discussing it.
