Speaking as a professional in this area, I doubt that any other provider who has a vested interest in maintaining their licensure would go around pumping hormones into teens willy-nilly. After carefully reviewing all birth control options with my teen patients, I allow THEM to DECIDE which method they feel would be the best option for them. I also make sure to inform them that all hormonal contraception has it's limitations - mainly, it's inability to protect against HIV and STIs. They are told this repeatedly. I'm suspecting that this practice takes place everywhere. There is no substitute for condoms...they are our friends.
Also, when it comes to confidentiality, I think it is essential. Many girls do not live in homes in which parents are receptive to them being sexually active. I always encourage the girls to tell their parents that they are sexually active and/or using contraception at some point, as I feel that honesty in the parent-child relationship is the best policy. However, I would not make a teenager's access to reproductive healthcare contingent upon their full disclosure to their parents. Certainly, I want parents to be informed about their child's health history, however, I would rather prevent disease and unwanted pregnancy from occurring up until the time that the child feels comfortable broaching this subject. How many of us told our parents where, when and with whom they were having sex. At least these teens are informed and taking a proactive stance in insuring their own protection. I applaud them for that. In addition, instead of demonizing the institutions that provide this service, I encourage parents to make their home a warm and receptive environment where a kid would feel safe having these conversations in the first place.
