How to Get Boy to Pay for Baby
Ellen Durston, a paper reporter in Chicago, always wanted her kickoff kid to be female. "Firstborn girls are more ambitious and confident than girls with an older sibling," contends Durston, 30, a secondborn. So when Durston and her hubby decided to excogitate, she began researching methods that would meliorate their odds of having a girl.

Durston came across a technique pioneered 30 years agone by the late obstetrics researcher Landrum Shettles, One thousand.D., Ph.D, who wroteHow to Choose the Sex of Your Baby. Subsequently following his communication, she became pregnant with Zoe, now 2. Would Zoe have been Zachary if the couple had left it to hazard? Quite possibly, by Durston's reckoning: "I'm convinced that the Shettles method is why I had a girl."
Jean and Robert Krak of McMurray, Pennsylvania had a similar experience. The proud parents of iii boys, ages 7, 6, and two, the couple "wanted a 4th child, and wondered if there was any fashion to slant the odds in favor of having a girl—to have the experience of raising a girl," says Jean.
An obstetrician gave her instructions for timing fertilization, intercourse positions, and using a douche to increment her chances of having a daughter. "He made no promises but said this technique had worked for others," says Jean. "Nosotros figured we'd try it, knowing that God all the same had the ultimate veto power." The family now includes their youngest, Angela Marie.
Dueling Theories
Gender preference is as old as conception itself, and then are theories about how to make it materialize—from ancient Talmudic communication that says if a wife's orgasm precedes her husband's, the baby will be a boy to Germanic sociology that suggests placing a wooden spoon under the bed ensures a girl. In the 13th century, a Chinese scientist created a chart that a woman could utilize to match her age to the month of the yr when she was likely to conceive a boy or daughter. Even in this scientific historic period, theories—and couples eager to exam them—abound.
Of them all, the Shettles method has the greatest following. Its premise is relatively simple: The Y-chromosome-carrying sperm (the one that results in a boy if it fertilizes an egg) is smaller, lighter, and faster-moving than sperm conveying the X (or female person) chromosome. Conversely, the slower-swimming Xs are more resilient.
Co-ordinate to Shettles advocate Pat Buie, writer ofCull the Sex of Your Infant Naturally, this means that male person sperm cells motility through the woman'south reproductive tract faster than female cells. In addition, an X sperm tin withstand a more than acidic surroundings, while a Y is more than likely to survive in an alkaline environment. Accordingly, Buie counsels couples who adopt a boy to fourth dimension intercourse to coincide with ovulation. This manner, the swift Y sperm can beat the competition to the just-ripe egg (if the Y has to await two days for an egg to be released, it will die).
She as well recommends rear-entry lovemaking (deeper penetration deposits the sperm closer to the cervix, thus avoiding the acidic vagina) and female orgasm, which increases cervical alkalinity. To conceive a girl, the Shettles method advises having sex no later than 2 days before ovulation (so that simply the hardy X sperm will be alive when the egg ripens); using the missionary position (and so that sperm penetrate less deeply and thus are exposed longer to the vagina's acidic secretions); and delaying female orgasm until later the man ejaculates.
Buie, a onetime nurse, maintains that the Shettles method has a 75 pct success rate overall and a 95 pct rate among her clients. There is little research, notwithstanding, to back upward her assertions. In fact, some research has found that the Shettles Method may increase a couple'south chances of having the opposite sexual activity of the one they want. I study found that couples who followed his communication had only a 39 percent chance of conceiving the gender of their selection. That'southward less than the 50-percent take chances they'd have if they let nature take its course.
"What Dr. Shettles proposed seems to make sense," says Masood Khatamee, M.D., an obstetrician-gynecologist at Mountain Sinai Beth State of israel in New York Metropolis. "But when put to the exam, his methods oasis't held up."
J. Martin Young, Thou.D., a private-do pediatrician in Amarillo, Texas, and author ofHow to Have a Girl and How to Have a Boy, says the flaws in Dr. Shettles's theory stem from its beingness based on bogus insemination. For couples conceiving naturally, Dr. Young prescribes the opposite course. "My method is based on the fact that at least 5 studies, some of which tested Dr. Shettles'due south theory, take plant that girls are usually conceived right at ovulation and that boys are conceived four to six days before and two days after ovulation," says Dr. Immature.
His recommendations? Have sex within 24 hours of ovulation to increase your chances of conceiving a girl to about 55 to sixty percent; to increase your odds of conceiving a male child to virtually 60 to 65 percent, have sex iv to six days preceding ovulation so abjure. The woman should remain yet for 20 minutes later on intercourse to increase the survival of all sperm and the chance of fertilization. In add-on, use a baking soda douche.
Amidst his satisfied customers are Julie and Wolf Puckett. Five years agone, the Amarillo, Texas, couple consulted Dr. Young'southward book for help in conceiving a boy. The Pucketts charted Julie's temperature to determine ovulation, then had intercourse several days before she was set to ovulate. Subsequently, Julie raised her hips with a pillow, every bit Dr. Young advises. Whether by design or by take chances, the system worked. The Pucketts' son, Hunter, is now 4.
The Ultimate Gamble
If these conflicting theories audio confusing, they are. Furthermore, at that place'southward no proof that they piece of work whatsoever better than the wooden-spoon method. Ane of the few reputable studies on the subject, published in the New England Periodical of Medicine, found no correlation betwixt gender and the timing of intercourse. "These theories simply don't stand up to scientific scrutiny," says Joshua A. Copel, 1000.D., a professor at Yale Academy School of Medicine.
Exercise-it-yourself methods are best regarded as harmless fun: fine to effort, as long equally would-be parents are open to a kid of either sex. (Those who aren't might well question the wisdom of becoming parents at all.) "In conception, gender is always a gamble," Dr. Copel observes, "and you take to be willing to accept any yous get."
Yet there are circumstances—a gender-linked illness, for instance—when sex preselection makes medical sense, in which example parents may desire to seek high-tech interventions.
Selective Services
For couples with a family history of certain diseases, gender choice is more an imperative than a preference. About 500 serious diseases, including hemophilia and Duchenne muscular dystrophy, develop simply in males (though females can be carriers). Increasingly, experts say, couples at adventure are using technology to avoid having a male child.
One method, called MicroSort, separates the X and Y sperm, then uses the desired kind to fertilize the egg either in vitro or through artificial insemination. The Genetics and IVF Establish in Fairfax, Virginia, where information technology was developed, says the method boasts a 91 percentage success rate with girls and a 74 percent rate with boys. However, after the FDA banned the use of sperm-sorting for sex selection in 2011, MicroSort is no longer available in the U.S. Instead, its labs are located in Mexico, Malaysia, North Republic of cyprus, and Switzerland. The visitor offers its services to married couples interested in family balancing and to families with genetic diseases; fees first at upwards of $three,000.
