Dear cocacola,

Yes, pregnancy is possible. There is no "birth control pill" available to men that prevents ejaculation or sperm production. You might want to think about whether your boyfriend was misinformed or if he lied to you about this. It's important for partners to be honest with each other and to protect themselves and each other against pregnancy and sexually transmitted infections.

If a girl is concerned about unintended pregnancy, she may want to consider taking emergency contraception (EC). EC — also known as the "morning-after pill" — is one of the safest and most effective ways to prevent unintended pregnancy after unprotected sex or contraceptive failure.

EC is effective if started within 120 hours — five days of unprotected intercourse. If started within 72 hours, EC can reduce the risk of pregnancy by 75-89 percent. So, the sooner it's started the better.

Plan B, a brand of EC, is available over the counter at many pharmacies for women over 18. Teens under 18 can still get EC with a prescription.

Call 1-800-230-PLAN for a Planned Parenthood center nearest you, or find us online. Planned Parenthood can also give you information about testing for sexually transmitted infections.

Hope this information helps!

Take care,
