Dear Dr. Locker: My husband and I are trying to conceive. I have waited 20 minutes on my back after sex with a pillow under my hips to help the sperm travel. Should I be concerned that the sperm sometimes comes back out? Sometimes it is even 3 hours later.
Answer from Dr. Locker
As long as you are staying on your back with your legs or hips up for at least 20 minutes then you are doing what most people recommend for conception.
Yes, most of the semen will come out at some point. For some women, if they stand up right after sex, the semen will spill out. For others, even if the woman stands up right after sex, the semen may stay inside her for a while, and then leak out or drip out minutes or hours later. So, yes, 3 hours later, as you mentioned, is totally normal. It will come out faster if you cough, sneeze, laugh, urinate, or do Kegel exercises. Just to be clear, though, you do not need to try to keep it in there for hours. As long as you are on your back with your legs or hips up for at least 20 minutes, you are doing fine for trying to conceive. (Many people do not even do that, and they can still get pregnant.)
Remember, one drop of semen contains millions of sperm, and usually some of the semen that is shot out during the ejaculation itself travels past the cervix at that time. Once there, sperm can stay alive for between 1 and 4 days (sometimes up to 7 days), so it can fertilize the egg days later. A few more notes...
In order to be most certain that you are having sex at the optimal time for conception, you can use Ovulation Predictor urine tests that you’d buy in a drug store, and/or you can chart your basal body temperature to be sure that you do not miss the day that you ovulate. For more information about this, you may enjoy the following book which goes into great detail about how to detect ovulation using the basal body temperature as well as cervical fluid. Plus, it explains more about when and how to have sex for conception.

For more information about how to conceive, please talk to your gynecologist or primary care doctor. I recommend that all women who are trying to get pregnant see your doctor for an annual exam. Also, when you start trying to conceive, it is usually recommended to take a prenatal vitamin (either over the counter or prescription), so talk with your doctor about that, too.
If you have been trying to conceive for one year with no success (or 6 months if you are over age 35), then you should consult your OBGYN doctor and/or a fertility specialist to get more information and advice, or to get fertility testing.
