If your referring to how to prevent pregnancy, there is a few methods. Condoms are one (a latex cover over the males sex organ). This is not 100% fool proof but it is better then nothing. Another is Birth Control (a pill that regulates the females reproductive system). Again this is not 100% fool proof but its safer then condoms. If used together, the chances are slimmed as well. Another thing to consider is the timing of having sex. Studies show that if you have sex the week after the completion of a females period, the risk is reduced even more. Though the only 100% safe, is the tried and true abstinence. If you do not have sex, then you cannot get pregnant.
