The role of the male orgasm in reproduction is pretty clear: It's a sperm delivery system. But, as the authors write, “the orgasm in women does not obviously contribute to the reproductive success, and surprisingly unreliably accompanies heterosexual intercourse.” Surprisingly unreliably. Pretty much sums it up, right?
Before ejaculating, the penis releases fluid, which people may call precum. This release is involuntary, and it can help with lubrication. Precum does not usually contain semen, but some semen can leak into it. This means that it is possible to become pregnant if precum enters the vagina.
What are the Chances of Getting Pregnant from Precum? The common answer is your chances are very low. However, there are rare cases where living sperm can be present in the precum and conception subsequently possible.
So if you use withdrawal for birth control, think about keeping emergency contraception (AKA the morning-after pill) in your medicine cabinet, just in case ejaculate (cum) gets in or near your vagina. Emergency contraception can prevent pregnancy for up to 5 days after unprotected sex.
It takes just one sperm to fertilize a woman's egg. Keep in mind, though, for each sperm that reaches the egg, there are millions that don't. On average, each time men ejaculate they release nearly 100 million sperm.
Your menstrual cycle begins on the first day of your period and continues up to the first day of your next period. You're most fertile at the time of ovulation (when an egg is released from your ovaries), which usually occurs 12 to 14 days before your next period starts.
The most reliable way to know if sperm has entered the egg is by taking a pregnancy test a few days after the anticipated start of your period. This test measures the level of human chorionic gonadotropin (hCG) in your urine, which is only present if your body is pregnant.
Pull-Out Method Effectiveness
Pulling out isn't a very reliable way to prevent pregnancy. It works about 78% of the time, which means that over a year of using this method, 22 out of 100 women -- about 1 in 5 -- would get pregnant. By comparison, male condoms are 98% effective when used correctly every time.

You can become pregnant any time during the menstrual cycle, even when you are not ovulating (which is when you have the greatest chance of conceiving). The chance of getting pregnant right after your period increases with each day after bleeding stops.
If semen (cum) gets ON the vulva or near the vaginal opening, sperm cells can swim into the vagina and cause pregnancy. This can happen if semen drips or is wiped onto the vulva, or if someone touches your vulva or vagina with fingers or sex toys that have wet semen on them.
Your menstrual cycle begins on the first day of your period and continues up to the first day of your next period. You're most fertile at the time of ovulation (when an egg is released from your ovaries), which usually occurs 12 to 14 days before your next period starts.
A woman is most fertile during ovulation. For a woman with 28 to 30 days menstrual cycle, ovulation takes place during the 10th to the 14th day. But there are still chances to of getting pregnant till the 21st day. So days 1 to 7 and 14 days before your periods are considered to be safe days.
What we do know is that withdrawal works about 78% of the time overall. But the odds of pregnancy are always higher during the 5 days leading up to, and during, ovulation — these are called fertile days. If no semen gets on your vulva or in your vagina, pregnancy can't happen — whether or not you're ovulating.
Have sex regularly. The highest pregnancy rates occur in couples who have sex every day or every other day. Have sex near the time of ovulation. If having sex every day isn't possible — or enjoyable — have sex every 2 to 3 days a week starting soon after the end of your period.
Confirming whether sperm has gone inside your body can be done by checking for semen, using a home pregnancy test, visiting a doctor, getting a sperm analysis, or using a fertility tracking method. If you are concerned about whether sperm has gone inside your body, it is important to speak with a healthcare provider.
Most couples will get pregnant within a year if they have regular sex and don't use contraception. But women become less fertile as they get older. The effect of age on men's fertility is less clear.
Ejaculated sperm remain viable for several days within the female reproductive tract. Fertilization is possible as long as the sperm remain alive — up to five days. Sperm can also be preserved for decades when semen is frozen.
Some women still believe that they can get pregnant any day of the month. This is simply not true! A woman is only fertile (meaning she can get pregnant) between 5-7 days each cycle. The only time a woman can get pregnant are the days around ovulation.
Some signs that can indicate sperm has entered include feeling a warm sensation and a change in the texture of vaginal secretions. It's important to always practice safe sex by using protection, such as condoms, to prevent unwanted pregnancy and the spread of sexually transmitted infections.
Some studies suggest that moderate ejaculation (2–4 times per week) is associated with a lower prostate cancer risk. However, ejaculating more often doesn't mean your cancer risk drops even more.
