After Having a Baby Can You Get Pregnant Easily Using the Pull Out Method
It starts with an historic period-old question: If a man pulls out before ejaculating, tin a adult female however become meaning?
In bedrooms, basements and the backs of cars worldwide, millions of sexually active humans brand choices (or regret them) based on what should be foundational fertility noesis. Most trusted sources say the answer is yes—information technology is unlikely but possible that pregnancy will occur, so don't take a chance information technology.
Dig deeper, though, and it quickly becomes unclear exactly where the risk is coming from. Instead of evidence-based education, you'll encounter some of the nigh durable misconceptions in sexual and reproductive health. When researchers analyzed a yr'due south worth of questions that were submitted to an emergency contraception Spider web site, they institute that well-nigh half of the questions that involved sexual acts "express fright about the pregnancy take a chance posed past pre-ejaculatory fluid."
Preejaculate—which pretty much everyone calls precum—is the lubricative secretion that is emitted, involuntarily, from the Cowper's gland in the penis during sexual arousal. Its job is to create a hospitable ride for sperm that ultimately pass through the urethra during ejaculation. Merely whether you query the Internet or an andrology expert about the fertilizing power of that egg-white goo, you're likely to become an reply to a different question—that is, a declaration that pulling out is a terrible class of birth control.
"When we're talking about what'south in preejaculate, that's not really the point," said Michael Eisenberg, director of male person reproductive medicine and surgery at Stanford University School of Medicine, subsequently I'd asked him the fertilizing-power question in various ways. "We know that pulling out is non effective at preventing pregnancy."
The pullout method—alternatively known every bit "withdrawing" or "pull and pray" and formally christened in Latin as "coitus interruptus"—is an ancient form of contraception. The Talmud refers to it every bit "threshing within and winnowing outside." Globally, it is still one of the near unremarkably used forms of birth control, especially in regions without access to modern methods. When performed perfectly every fourth dimension, information technology actually has a failure rate that isn't much higher than that of condoms: 4 percent versus two per centum, respectively. That means about four out of 100 women who rely on the pullout method exclusively will become significant during one year of utilize.
But existent life is rarely perfect. Some males cannot reliably perceive the imminence of ejaculation and withdraw too late. Others might emit semen intermittently or over a long menstruum of time instead of equally a unmarried issue, according to a 1970 family-planning manual. A lot of men don't realize that the highest concentration of sperm occurs in the starting time spurt of semen—which tin can be especially problematic if getting drunk slows down their reaction time. Still others don't pull out in time because their pleasance takes precedence over a woman'south health and well-being. For reasons such as these, the "typical use" failure rate of coitus interruptus jumps to betwixt 20 and thirty percent.
People in the reproductive-health field largely dismiss the pullout method because they don't believe men have the ability and willpower to withdraw at the correct time, every time. Meanwhile there is a shocking lack of research on whether or not viable sperm are actually present in preejaculate.
The best fashion to synthesize the answers I collected from physicians, peer-reviewed journals and educational institutions is this: Preejaculate itself does not contain sperm—or peradventure it does occasionally, but peradventure it gets contaminated with sperm that has "leaked" from elsewhere. Plus, at that place's leftover sperm from previous ejaculation. And anyway, Eisenberg says, we should assume that preejaculate "usually has some sperm, which tin can atomic number 82 to [contraception] failure."
It is obvious to blame inadequate sexual activity teaching for our collective confusion. But ironically, write the authors of a 2009 Contraception newspaper, "the notion that pre-ejaculatory fluid can cause pregnancy ... seems to accept been introduced by the medical profession itself."
Dispelling a Myth?
Where did the fertile prowess of preejaculate originate? Perhaps it was in 1931, when Abraham Rock—a physician and colleague of Planned Parenthood founder Margaret Sanger—wondered how information technology was even possible for the withdrawal method to fail: Sperm are made in the testicles and don't route through the Cowper's gland on their style out. Stone asked some buddies with microscopes to examine their preejaculate for sperm. Among the 24 samples from 18 men, only four contained many or a few sperm. In a 1938 volume, Practical Nascency-Control Methods, Stone wrote that these figures were insignificant. Regardless, a "myth" that a scattering of sperm in preejaculate makes coitus interruptus unreliable took off, and it was "copied uncritically from one textbook another," according to the 1994 edition of the book Fertility Command.
This myth was popularized past the classic 1966 textbook Homo Sexual Response, past William H. Masters and Virginia E. Johnson, according to the Contraception paper. These pioneering sexual activity researchers "warned of the possibility of pregnancy from withdrawal due to the presence of sperm in secretions of the Cowper'due south gland"—a statement that "was apparently not evidence-based merely subsequently repeated," the authors write.
The Contraception paper's authors also speculate on why sperm seem to have "boggling potency" in the eyes of the public. In textbooks and the media, sperm are "oft anthropomorphized as masculine, forceful, competitive, and single-mindedly determined to fertilize the egg against all obstacles," they write. Indeed, the memorable 1989 educational picture show The Making of Me features cartoon sperm "men" in a literal race for a sexualized egg "woman," set to a soundtrack that includes Richard Wagner's "Ride of the Valkyries." Additionally, girls often learn to be terrified of sperm yet aren't taught how their own body works: A recent survey of i,000 American women of reproductive age found that lxxx percent of them were not able to correctly answer how many days of each cycle they are fertile.
Since Stone's experiment, there has been little incentive to research coitus interruptus at all, partly because unlike condoms or intrauterine devices (IUDs), at that place's no contraceptive product to sell. While the pregnancy risk of preejaculate has just been investigated a handful of times, the results challenge pop assumptions and enhance new questions.
Here'southward what the literature tells u.s.a.: In the early 1990s, a study examined the preejaculate of HIV-positive men to determine if the virus was nowadays. (Information technology was.) An ancillary simply "more pregnant" finding described in Contraceptive Engineering science Update was that "about pre ejaculate samples did not contain any sperm and those that did had simply small clumps of a very modest corporeality of sperm which seemed to be immobile." If a larger study confirmed the results, the article said, information technology "may dispel the myth that pre ejaculate fluid contains sperm."
Only tiny studies have taken place since. In a 2003 experiment with 12 Israeli men who gave at least two samples of preejaculate each, scientists examined the secretions under a microscope and constitute that none of them independent sperm. Another small-scale study besides found no sperm.
Several years ago, researchers in England and the U.S. set out to more than rigorously investigate the fertilizing potential of preejaculate, noting that "no report has found motile sperm in the pre-ejaculate." Their paper, published in Human being Fertility in 2011, analyzed forty samples of preejaculate from 27 volunteers. Ten of the volunteers (37 percent) produced samples that included "a reasonable proportion" of motile sperm.
Because some of the men gave samples on multiple split occasions, an intriguing blueprint emerged: sperm was present in either all of an private'southward samples or in none of them. "Information technology would announced from our study," the authors wrote, "that some men repeatedly leak sperm in their pre-ejaculatory fluid while others do not."
They therefore ended, "it is tempting to speculate that the use of withdrawal as a means of contraception might be more successful in some men because they are less likely to release sperm with their pre-ejaculate."
Then, in 2016, a larger study of 42 good for you Thai men reported that "actively mobile sperm" were found in only 16.7 percent of the subjects. Unfortunately, the researchers did non collect preejaculate samples on multiple occasions.
To make sense of these alien data, I called John Amory, a physician and professor at the University of Washington, who is known for his research on male infertility and novel forms of contraception. I asked him almost the plausibility of this "two groups" concept: the thought that men might either ever take sperm in their preejaculate or never have it.
Amory responded with surprise. "See, I didn't even know that," he said almost the studies. "Nosotros were taught [in medical training] that sperm were left over from the last ejaculate." This is a pop theory. Planned Parenthood similarly says that preejaculate "may selection upwards sperm from a previous ejaculation as it passes through a man'south urethra." Wikipedia promotes a familiar fix: simply urinate before intercourse, the logic goes, and you'll flush out lingering sperm.
Though the acidity of urine does harm sperm, I could not find whatsoever testify to bear witness that this strategy is solid. In fact, researchers in the 2011 Human being Fertility newspaper wrote that the volunteers giving samples had, of class, gone to the bath several times since their last ejaculation. Therefore, every fourth dimension the authors observed sperm in preejaculate, the contamination "must have taken place immediately prior to ejaculation." Clearly, at that place are consequences to misunderstanding this facet of male fertility.
"Fertility Is a Team Sport"
Because nosotros know so niggling about sperm in preejaculate, the failure rate of pulling out is really more of an "educated judge" and a topic of controversy amongst experts in the field. The reality is that lots of people in the U.S. employ this method to avoid pregnancy. So, do males approach withdrawal equally a serious class of contraception and take responsibleness for learning how to maximize its efficacy? While plenty of men feel confident discussing the minutia of abortion and female person reproductive parts they tend to exist quite ignorant of their own fertility.
Greg Sommer discovered just how few males understand their contribution to pregnancy when he launched an at-dwelling sperm-testing kit chosen Trak. In 2017, he brought his product to the Consumer Electronics Prove in Las Vegas. "We had a demo kit at our booth, and I tin can't tell you how many guys came up and said, 'So, what, I pee in the loving cup?'"Sommer recalls. "And we had to tell them, 'No, there's no sperm in your urine.'"
Sperm awareness got a boost in 2017, when a meta-analysis showed that sperm counts of men from the U.Southward., Europe, Commonwealth of australia and New Zealand had dropped by more than 50 percent in less than 40 years. "Men are responsible for near one-half of infertility cases only accept way likewise long to go a semen analysis when they are not conceiving naturally," Sommer says. The study was widely framed as a potential crisis in male fertility, sparking some men to consider their sperm functionality more securely—or merely consider it at all.
Whereas women have long shouldered the burden of both preventing pregnancy (with drugs) and causing pregnancy (with assisted-reproduction technologies such equally egg freezing), "in that location is a growing understanding that fertility is a team sport," Eisenberg says. "Nosotros need to understand more almost the male side."
Recent population surveys have shown that many men practice want more birth-control options. Without contraception methods beyond condoms, vasectomy and withdrawal, some guys are already doing "all sorts of crazy and potentially unsafe things to brand themselves less fertile to avoid pregnancy," Sommer says.
In discussion forums on Trak's infertility education Web site at www.dontcookyourballs.com Sommer found that some men "are biohacking themselves" by using prescription steroid creams to intentionally squash sperm count. Others sit down in a hot tub every day. I guy wrote about his "hacked-upwards underwear heater-type device with a little bombardment pack," Sommer says. "Don't underestimate men's drive and creativity when it comes to having a amend sexual activity life"—pregnant men will indeed make efforts and take risks to have sex without condoms.
The Center for Male Contraceptive Enquiry & Development even exploits this incentive to solicit volunteers for clinical drug trials. One image on the centre's Instagram business relationship features a boxer with a punching pocketbook. "Done with condoms? Join the fight for male person birth control," it reads, followed past the hashtag #LoveWithoutTheGlove. Information technology seems to be working: A major clinical trial for a hormonal gel began late last yr.
It sounds woefully apropos that scientists and entrepreneurs are convincing guys to learn about reproductive responsibility past appealing to their sexual pleasance—especially at a time when some U.S. lawmakers want to investigate the "criminality" of miscarriages and classify treatment for ectopic pregnancy as an "ballgame."
All the same more than options and knowledge for preventing pregnancy are good things for everyone. Later on all, near half of all pregnancies in the U.S. are unintended, and the lack of access to birth control and health care providers is non the simply problem. 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 nascency control, nosotros 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 means of life. In addition to hormones and IUDs, researchers could investigate "proteins, enzymes and genes involved in the reproductive process that could be targeted to prevent pregnancy in both women and men—and potentially practise and so in more precise ways," wrote announcer Maya Dusenbery in the May issue of Scientific American.
With a personalized-medicine approach, imagine if nascency control could be catered to the specific needs and priorities of an individual. In some cases, the task of preventing pregnancy could exist truly shared between a couple. "What if the male partner is willing to have on some of the risks and side effects to lower the risks and side effects of his female partner?" Amory says. "No 1 has really talked about the idea of reframing risk paradigms."
Until this equitable future arrives, understanding the fertilizing potential of an private'southward preejaculate could give some men another way to participate in the responsibility of contraception. Allow's say that males do fall into two groups, equally the Homo Fertility study speculates. What if a man—my beau, for instance—could undergo a preejaculate sperm evaluation?
If so, my beau and I might scientifically resolve the last variable in our nativity-control efficacy. We utilize coitus interruptusone 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 torso for up to v days.) I determine this window using a technique chosen the symptothermal method, a means of avoiding pregnancy that involves meticulously tracking changes in cervical fluid and basal-torso temperature in guild to predict, and then ostend, when ovulation occurs.ii
We devised this contraception strategy based on our personal risk-benefit analysis and combined physiologies—and information technology has worked for us so far. But I'd prefer to empirically validate the absence (or problematic presence) of sperm in my boyfriend's preejaculate. Frustrated past the paltry research, I decided to comport an experiment myself.
For Science!
The Trak test, while approved past the Food and Drug Administration, is not designed for testing preejaculate. Nor is it intended to be used as form of pregnancy prevention. Only co-ordinate to Sommer, it is sensitive enough to option upwards on sperm concentration equally low every bit one million per milliliter (M/mL). While that sounds like a lot, "the chance of pregnancy is extremely depression," Amory says. "In fertility settings, we take intendance of a lot of men with those counts who never conceive spontaneously." The World Health Organization has determined that suppressing sperm counts to this threshold appears to subtract the chances of conception to less than 1 percent per year.
I ordered a Trak fertility kit and recruited one written report participant: after assuring my boyfriend that his genetic material wouldn't exist sent off to a lab and terminate up in a database (Trak isn't connected to the Cyberspace), he gave me his informed consent.
First, nosotros did a command test to go a sense of his sperm baseline. After 48 hours of abstinence (the minimum length of time for proper semen analysis, co-ordinate to the WHO), he proffered a v-milliliter ejaculation sample. Per the instructions, nosotros let it sit for 30 minutes to liquefy, gave it a good swirl, and then deposited a pipette's worth of fluid into a test prop. That went into the Trak "engine," an adorably sized, battery-powered centrifuge.
My boyfriend stared downwardly the engine until information technology beeped to indicate its finish, recalling the way women glare at pregnancy tests while awaiting the results. A white column in the prop reached above the 55 Chiliad/mL mark, signaling that his sperm concentration fabricated it into the "optimal" range for formulation. After another 48 hours of abnegation from ejaculation ("for consistent science," I insisted), it was time to examination his preejaculate.
"I think accurately testing merely precum might be a challenge," Sommer wrote when I informed him of my plans to use his exam for off-label endeavors. "Collecting a sample via masturbation might accept different discharge dynamics than during intercourse."
The hallowed pages of Scientific American are not the place to describe how we collected a full milliliter of unadulterated preejaculate. I volition say that our methodology was informed by the science of arousal, a commitment to rigorous research standards and an affluence of sense of humor.
Per the discussions of methodology in the academic studies, we knew it was critical to collect simply 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 plant to incorporate sperm was artificially loftier. In other words, the subjects might have been sloppy, leading to imitation positives.
(Anecdotally, appealing to male pride created a strong motivation for my volunteer to endure the 30-ish minutes information technology took to think enough book of pure preejaculate to run the Trak test. "Wow, look at how much you're producing," I cheered virtually halfway through. By comparing, the bookish study subjects were likely masturbating, presumably alone, in a lab, and I humbly hypothesize that they may accept gotten bored. The authors of the 2011 Human Fertility study even suggested that subjects might have knowingly handed over samples of ejaculate fluid because they were embarrassed they couldn't produce sufficient preejaculate.)
We ran the preejaculate test but equally with my boyfriend's ejaculate: a full pipette of well-mixed fluid went into the prop, followed by a 6-minute spin in the centrifuge. Then nosotros peered into the measuring strip nether brilliant low-cal and couldn't find fifty-fifty a speck of white. If in that location was sperm present, the concentration was likely beneath i one thousand thousand per milliliter, which means my boyfriend'due south preejaculate sample could be considered infertile by WHO standards.
Though promising, one at-home exam doesn't confirm anything. We would demand to replicate this experiment several more times. Sperm count in semen changes over fourth dimension and is afflicted by health factors, and then perhaps the same is truthful for preejaculate. Because Trak is not intended for such diagnostics, it would exist all-time to compare the results of our experiments with lab tests at a fertility clinic (if they'd even indulge such a request).
Larger questions abound: Fifty-fifty if in that location are sperm in preejaculate, tin they swim? Are all of their parts intact? And if the sperm present in preejaculate aren't merely "left over" from the last ejaculation, then from where might they be "leaking," as the literature suggests?
Filling these cognition gaps has the potential to fine-tune the math of pregnancy risk. Imagine if males were able to better judge whether the pullout method is a useful tool in their contraception arsenal or, more critically, whether information technology is besides risky even when the act itself is performed correctly every fourth dimension.
After all, contraceptive use in the existent earth is more varied and circumstantial than the behavioral patterns that determine "failure rates." Few people use only ane method in the aforementioned exact way every time they have sexual practice. Recent surveys suggest that coitus interruptus is really employed more than frequently than previous research suggests and often in conjunction with other methods. If some men do consistently take viable sperm in their preejaculate, it might help explain the 4 percent failure rate of the withdrawal method despite "perfect" utilise. Information technology would not be the commencement time the medical field was incorrect to blame contraceptive failure on user mistake instead of physiological variation.
At the least, researching the mechanisms of preejaculate and pregnancy risk could add together evidence-based dash to sexual activity pedagogy. As Amory told me after reviewing the studies on preejaculate, "I think this is an example of when y'all drill down on a 'truth,' i finds it's not based on much."
1. Nosotros could utilise condoms during my "fertile window," merely their failure rate over fourth dimension is not significantly lower than coitus interruptus . Given the all-time available science and our personal considerations, nosotros chose to be in command over preventing user mistake rather than run a risk the dubiety of product failure.
2. The symptothermal method should not be confused with the rhythm method or similar counting techniques. With perfect use, it tin exist just every bit effective as the pill at preventing pregnancy. While I chart my data in a cycle-tracking app, I do not consult predictive algorithms to determine when I am fertile. Similar all contraceptive methods, the symptothermal method is certainly not correct for everyone. It can, nonetheless, be used equally an excellent educational tool for learning about fertility and reproductive health.
