For the pull-out method to be effective, the male must know precisely when they will ejaculate, and be able to withdraw before.
This can take practice. Practicing when masturbating or using condoms during sex can help. It can also be tricky because the pull-out method may reduce physical pleasure or make it more difficult for one or more of the sexual partners to reach climax.
That means that some people may be reluctant to pull out before ejaculating or feel tempted to cut it close with their timing. To be effective, all sexual partners must make sure that no semen comes into contact with the vagina or vulva. This includes when cleaning up after ejaculation, and people must make sure to clean their hands and penis before any further sexual activity. Many people wonder whether the pull-out method works, even when performed properly because pre-ejaculate or pre-cum still enters the vagina.
This refers to the fluid that leaves the penis before ejaculation. This is a very common question. In fact, one study reports that around half of the email questions an emergency contraception website received in one year asked whether pre-cum could cause pregnancy.
According to the OWH , some sperm may still leave the penis before withdrawal. They say that pre-cum may contain sperm. If it does, the female could become pregnant.
However, there is some scientific debate over whether pre-cum contains viable sperm. Only a few studies have looked into it, and the results tend to be inconsistent. This is likely due to the differing collection methods, sample populations, and small numbers of participants. According to an article in Human Fertility , the function of pre-cum is to lubricate the genitals and help create safe pH conditions for semen to travel through later.
An earlier study that examined pre-cum samples from 12 males and reported that no samples contained active sperm. However, a study found that pre-cum samples from 11 out of 27 healthy male subjects contained sperm, 10 of which contained mobile or viable sperm. A study also found active sperm in However, the authors note that samples may have become contaminated during collection. In summary, some experts believe that pre-cum should not contain sperm, but that it may contain a small, viable amount under some circumstances.
Unfortunately, there is currently no easy way to test the sperm content of pre-cum. Pregnancy risk also heavily depends on whether the female is ovulating. Female fertility changes throughout the menstrual cycle, and they are most likely to get pregnant around ovulation, known as the fertile window.

Greg Sommer discovered just how few males understand their contribution to pregnancy when he launched an at-home sperm-testing kit called Trak. Sperm awareness got a boost in , when a meta-analysis showed that sperm counts of men from the U. The study was widely framed as a potential crisis in male fertility, sparking some men to consider their sperm functionality more deeply—or just consider it at all. Recent population surveys have shown that many men do want more birth-control options.
Others sit in a hot tub every day. It seems to be working: A major clinical trial for a hormonal gel began late last year. It sounds woefully apropos that scientists and entrepreneurs are convincing guys to learn about reproductive responsibility by appealing to their sexual pleasure—particularly at a time when some U.
Yet more options and knowledge for preventing pregnancy are good things for everyone. After all, nearly half of all pregnancies in the U. Nearly 40 percent of women are not satisfied with the birth-control method they are currently using, according to the Guttmacher Institute. When people dislike their contraception for whatever reason—including health side effects from the pill or the tactile compromises of condoms— they are less likely to use it correctly and consistently.
One day, if the pharmaceutical industry decides to reverse course and fund the development of innovative birth control, we could get genetic tests and other technologies to help people of both sexes figure out what kind of contraception might work best for our individual physiologies and ways of life.
With a personalized-medicine approach, imagine if birth control could be catered to the specific needs and priorities of an individual. In some cases, the task of preventing pregnancy could be truly shared between a couple. What if a man—my boyfriend, for instance—could undergo a preejaculate sperm evaluation?
If so, my boyfriend and I might scientifically resolve the final variable in our birth-control efficacy. We use coitus interruptus 1 during my fertile window, the weeklong span during which his sperm can potentially fertilize my egg. An egg is only viable for fertilization for up to 24 hours per menstrual cycle, and sperm can survive in the female body for up to five days.
I determine this window using a technique called the symptothermal method, a means of avoiding pregnancy that involves meticulously tracking changes in cervical fluid and basal-body temperature in order to predict, and then confirm, when ovulation occurs. We devised this contraception strategy based on our personal risk-benefit analysis and combined physiologies—and it has worked for us so far.
Frustrated by the paltry research, I decided to conduct an experiment myself. The Trak test, while approved by the Food and Drug Administration, is not designed for testing preejaculate. Nor is it intended to be used as form of pregnancy prevention. First, we did a control test to get a sense of his sperm baseline. After 48 hours of abstinence the minimum length of time for proper semen analysis, according to the WHO , he proffered a five-milliliter ejaculation sample.
My boyfriend stared down the engine until it beeped to signal its finish, recalling the way women glare at pregnancy tests while awaiting the results. The hallowed pages of Scientific American are not the place to describe how we collected a full milliliter of unadulterated preejaculate. I will say that our methodology was informed by the science of arousal, a commitment to rigorous research standards and an abundance of humor.
Per the discussions of methodology in the academic studies, we knew it was critical to collect only preejaculate. The authors of the Thai paper wrote that study volunteers might have smeared semen on the collection slides instead of preejaculate, which could mean the number of preejaculate samples that were found to contain sperm was artificially high.
