Contraception does much more for teenage girls than make it less likely to become a young mom. Many young girls get bad pains and cramps due to their period and have an extremely heavy flow. Contraception lessens the pain during this time and usually makes the bleeding lighter. I think most girls with this problem NEED to be on it, especially when the pain is unbearable.
In a society in which people are having sex at increasingly younger ages, contraceptives are becoming more of a necessity. Denial of birth control will not stop teenagers from having sex if that's what they want to do, and such a policy will only serve to increase the percentage of teens having unsafe sex. As a result, we will be seeing greater rates of teen pregnancies and subsequently higher rates of children born to teen parents. Pretending that teen sex is a myth only serves to compound the exact problems that the denial of such prescriptions seeks to prevent.
I agree that doctors should be able to prescribe contraception for girls under the age of 16. Today girls are becoming sexually active at younger ages. Teenage girls are getting pregnant at a high rate and with that comes some really serious health risks and there are negative social and economic consequences too.
No, doctors should not be allowed to prescribe contraception for girls under the age of 16, because sexual activity is too much for people who are essentially still children. Also, being on contraception for a long time in a woman's life can cause health problems, for example increasing the risks of stroke. They should wait until they are 18, at least.
