Pregnancy Home > Can You Get Pregnant From Oral Sex?

Pregnancy cannot occur through oral sex alone. However, oral sex does not protect you or your partner from sexually transmitted diseases (STDs). Be sure to use a condom if one of you has a sexually transmitted disease, such as herpes.

Getting Pregnant From Oral Sex: Is It Possible?

Getting pregnant from oral sex alone is not possible. To understand this, let's briefly talk about how pregnancy occurs.
For pregnancy to occur, the sperm, which are in the semen, must enter the vagina, travel up through the cervix, into the uterus, and then into the fallopian tube to meet up with the egg. Once this happens, the sperm must fertilize the egg, and the resulting blastocyst (fertilized egg) must travel down the fallopian tube and implant in the uterus.
Sperm are able to enter the vagina when ejaculation or pre-ejaculation occurs inside or near the vagina. During oral sex, even if semen is swallowed, the mouth, throat, etc. are not connected in any way to the female reproductive tract (i.e., vagina, cervix, uterus, fallopian tubes).

Other Thoughts on Pregnancy and Oral Sex

If you are looking for a way to be sexual with your partner and not worry about becoming pregnant, oral sex is probably your best choice. But there are some other things to consider to stay healthy when having oral sex:
  • Oral sex does not protect you or your partner from sexually transmitted diseases (STDs). If you have an STD, such as herpes (oral or genital), do not have oral sex without a condom -- you could give it to your partner. In addition, you or your partner could have open sores in your mouth and transmit a number of other STDs in this manner.
  • Make sure that your partner does not put his penis in your vagina after oral sex until it has been cleaned off. It could have semen on it -- increasing your chances of becoming pregnant.
