Among the 24 samples from 18 men, only four contained many or a few sperm.
Stone asked some buddies with microscopes to examine their preejaculate for sperm. Where did the fertile prowess of preejaculate originate? Perhaps it was in 1931, when Abraham Stone- a physician and colleague of Planned Parenthood founder Margaret Sanger-wondered how it 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 way out. seems to have been introduced by the medical profession itself.” Dispelling a Myth? But ironically, write the authors of a 2009 Contraception paper, “the notion that pre-ejaculatory fluid can cause pregnancy. It is obvious to blame inadequate sex education for our collective confusion. And anyway, Eisenberg says, we should assume that preejaculate “usually has some sperm, which can lead to failure.” Plus, there’s leftover sperm from previous ejaculation. The best way to synthesize the answers I collected from physicians, peer-reviewed journals and educational institutions is this: Preejaculate itself does not contain sperm-or maybe it does occasionally, but perhaps it gets contaminated with sperm that has “leaked” from elsewhere. Meanwhile there is a shocking lack of research on whether or not viable sperm are actually present in preejaculate. 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. For reasons such as these, the “typical use” failure rate of coitus interruptus jumps to between 20 and 30 percent. Still others don’t pull out in time because their pleasure takes precedence over a woman’s health and well-being. A lot of men don’t realize that the highest concentration of sperm occurs in the first spurt of semen-which can be especially problematic if getting drunk slows down their reaction time.
Others might emit semen intermittently or over a long period of time instead of as a single event, according to a 1970 family-planning manual. Some males cannot reliably perceive the imminence of ejaculation and withdraw too late. That means about four out of 100 women who rely on the pullout method exclusively will become pregnant during one year of use.īut real life is rarely perfect. When performed perfectly every time, it actually has a failure rate that isn’t much higher than that of condoms: 4 percent versus 2 percent, respectively. The Talmud refers to it as “threshing inside and winnowing outside.” Globally, it is still one of the most commonly used forms of birth control, particularly in regions without access to modern methods. The pullout method-alternatively known as “withdrawing” or “pull and pray” and formally christened in Latin as “coitus interruptus”-is an ancient form of contraception. “We know that pulling out is not effective at preventing pregnancy.” “When we’re talking about what’s in preejaculate, that’s not really the point,” said Michael Eisenberg, director of male reproductive medicine and surgery at Stanford University School of Medicine, after I’d asked him the fertilizing-power question in various ways. But whether you query the Internet or an andrology expert about the fertilizing power of that egg-white goo, you’re likely to get an answer to a different question-that is, a declaration that pulling out is a terrible form of birth control. Its job is to create a hospitable ride for sperm that ultimately pass through the urethra during ejaculation. 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.
When researchers analyzed a year’s worth of questions that were submitted to an emergency contraception Web site, they found that almost half of the questions that involved sexual acts “express fear about the pregnancy risk posed by pre-ejaculatory fluid.”
Instead of evidence-based education, you’ll encounter some of the most durable misconceptions in sexual and reproductive health. Most trusted sources say the answer is yes-it is unlikely but possible that pregnancy will occur, so don’t risk it.ĭig deeper, though, and it quickly becomes unclear exactly where the risk is coming from. In bedrooms, basements and the backs of cars worldwide, millions of sexually active humans make choices (or regret them) based on what should be foundational fertility knowledge. It starts with an age-old question: If a man pulls out before ejaculating, can a woman still get pregnant?
