Can you really choose the sex of your baby?

"For as long as we've been having babies, women have been exchanging ideas about how to have either a boy or a girl. Unfortunately there's no medical evidence that any of them actually work!
Having said that, there'll always be a mum who tells you an old wives' tale worked for her. So if you fancy defying the experts and trying to tip the balance towards one sex yourself, why not try some of the suggestions below.
You're more likely to conceive a boy if...
- You have sex on the day of ovulation, as male sperm are thought to swim faster and reach the egg first
- you reach orgasm before your partner, as this releases an alkaline fluid, thought to be more male-sperm friendly than the vagina's natural acidity
- you have deep penetration during sex, such as rear-entry (doggie-style)
- your partner has a high sperm count. This is because male sperm are not as strong as female sperm, and so the higher the count, the more chance there is of a male sperm reaching the egg first
- you avoid sex for a week before ovulation and then only have sex once on ovulation day, to keep the sperm count high
- your partner suggested the love-making
- you make love at night
- you make love on odd days of the month
- your partner keeps his genitals cool by wearing boxer shorts and loose-fitting trousers
- you eat salty food, plenty of meat, fish, white flour, pasta, fresh
fruit, certain vegetables, but avoid milk and dairy products, such as yoghurt and cheese, nuts, chocolate, shellfish and wholemeal bread."

There really is no way to interfere with nature's processes through diet, etc. Don't believe it if someone tells you otherwise. There is only one way to determine the gender in advance and that is by artificial conception processes. You have a 50/50 chance of having a girl this time. I'm sure you will love and enjoy your baby no matter what sex it turns out to be!
Although this wish tops every pregnant woman's list, many moms-to-be harbor a secret, or not so secret, desire for a boy or a girl.
At some fertility clinics, high-tech sperm-spinning can yield the preferred gender up to 90 percent of the time. But for couples who can't afford this pricey procedure, or who shudder at the idea of "playing God," employing one of the more natural sex selection methods may help them get the baby they want inexpensively, without stepping on Mother Nature's toes.
Old Wives' Tales
Folklore is full of creative, often wacky, suggestions for choosing a baby's sex. According to the Old Wives, women should eat meat and salty food to get a boy, or splurge on desserts to get a girl. Couples supposedly are more likely to conceive sons if they make love standing up or when there's a quarter moon. Conversely, daughters are in the picture if partners use the missionary position or have sex during a full moon.
The Chinese conception chart, which has been around for some 700 years, tells women what dates will result in boy or girl conceptions based on the mother's age and the month of conception.
These methods are entertaining to read about, and in some cases to practice, but none has any legitimate scientific merit. For example, going by the Chinese conception chart, this writer's son should have been a daughter.
The Shettles Method
In the early 1960s, Dr. Landrum B. Shettles published a groundbreaking report on the distinctive characteristics of Y-bearing (boy-producing) and X-bearing (girl-producing) sperm. He asserted that the Y sperm are lighter in weight, swim faster, but die sooner; the X sperm are heavier, swim slower, but live longer. Shettles expanded this central thesis into a low-tech method of gender selection. His resulting book, How to Choose the Sex of Your Baby, co-written by David M. Rorvik, was first published in 1970 and since has become the sex-selection bible for couples interested in non-invasive, low-tech family planning techniques. In the 1997 edition, Shettles claims a conservative 75 percent success rate for partners who employ his method scrupulously.
To take advantage of sperm speed and staying power, the timing of intercourse plays a critical role in achieving the desired gender. To get a boy, Shettles advises couples to have sex as close to ovulation as possible. During ovulation a woman's vaginal and cervical fluids become alkaline, a condition that makes conception more favorable for either sperm, but especially for the less hearty Y sperm. And because the Y sperm move quicker than the female-producing sperm, they are more likely to win the race to the egg. Prior to and following ovulation, vaginal and cervical secretions are acidic. If intercourse occurs under these conditions, the heartier X sperm are more apt to survive in the reproductive tract for a couple of days until the egg arrives.
Because many women don't know when they're ovulating, Shettles suggests they track several cycles to observe their body's signals before attempting conception. By checking the condition of her cervical mucus (CM), also known as cervical fluid (CF), and tracking her basal body temperature (BBT) for a few months, a woman should be able to pinpoint the day of ovulation and the fertile days leading up to it.
Ovulation kits available in pharmacies also can determine when a woman is ovulating, but these kits are expensive and may not be accurate for women with irregular cycles.
How to Get a "Shettles Girl"
According to Shettles, girls are harder to come by than boys. Couples need to be patient; conceiving a girl may take several months. The reason for this is that partners trying for a daughter need to stop having sex at least 2 days before ovulation, so more X sperm than Y sperm will be around to meet the egg. Even though the Xs have better staying power, it's tougher (but not impossible) for either sperm to last more than a few days. That said, the basic method to conceive a girl is this:
Immediately after a woman's menstrual period ends, she and her partner should have intercourse frequently (at least every other day) until 48 hours before ovulation. Shettles stresses that continuing to have sex beyond this point diminishes the chances of getting a girl.
How to Get a "Shettles Boy"
In a nutshell, couples hoping for a boy should do the following:
Either abstain from sex or use condoms until 4 days before ovulation. After this point, abstain entirely until 12 hours prior to ovulation; this sexual respite acts to boost a man's sperm count, a condition that Shettles maintains favors male sperm. During the 12-hour ovulatory window, a couple should have sex, preferably just once. After this, partners must use condoms if they have intercourse again in the next several days.
Bethany, a 30-year-old homemaker in Illinois, could be the Shettles Method Poster Mom. Bethany and her husband assiduously followed the techniques outlined in Shettles' book when they conceived each of their five children. With four out of the five, they got pregnant on the first try; only one baby took two months to conceive. And most impressive, this couple achieved the desired gender with all of their kids: Lindsey, Hayley, Makenna, Camden (the only boy) and Amrin.
To conceive their daughters, Bethany and her husband made love on the third and second days before she ovulated. They also used the missionary position, which Shettles asserts "makes it less likely that the sperm will be deposited directly near the opening of the cervix, where the secretions are most alkaline and would thus favor the male-producing sperm."
In the 1997 edition of his book, Shettles discounts his previously recommended "girl" tip of douching with vinegar and water. However, Bethany used this acidic combination when she conceived her girls. While it's unclear if the douching helped, it obviously didn't hurt.
Bethany and her husband conceived their son, Camden, on the day she ovulated. They used the "rear-entry" position, which Shettles maintains places the sperm closest to the cervix, where the secretions are the most alkaline, and thus boy-producing. To boost the alkaline content of her fluids even further, Bethany douched with baking soda and water.
When asked how she feels about having employed Shettles' somewhat rigorous techniques, Bethany gives her conception experience a big thumbs-up. "It was not intrusive – more fun than anything. You just have to keep in mind that it really does not matter what you get. Love them no matter what."
However, not every couple is as successful using the Shettles Method as Bethany and her husband. Referring to her Shettles attempt to get a girl, Madeleine*, a 36-year-old mom of four, says this:
"We followed the instructions perfectly. We went to the end of the scale following the belief that girls live longer and we had sex five days before ovulation, [resulting in conception]."
But the girl that Madeleine was trying for turned out to be a boy. Although Madeleine initially felt sad that her daughter would not realize her dream of having a little sister, she stresses that "the minute I saw my son I fell in love and I know he was sent to us for a very special reason."
The Whelan Method
In Boy or Girl?, a lesser-known book on low-tech gender selection, author Elizabeth Whelan, Sc.D., details a method that directly contradicts Shettles' theories. Basing her technique on the research of Dr. Rodrigo Guerrero of Colombia, Whelan states that Shettles' approach to timing intercourse only applies to couples undergoing artificial insemination.
She explains that for those partners conceiving the old-fashioned way, intercourse timed closer to ovulation is likelier to result in a girl and having sex earlier in the cycle will favor boy conception. Further, Whelan promises a lower success rate than Shettles: 68 percent for boys and 57 percent for girls.
Dr. Shettles devotes several pages of his book to attacking Whelan's theories. He even includes a letter written by a woman who takes Whelan to task and touts Shettles' techniques as superior. Shettles maintains that Whelan's book "has fallen into merciful obsolescence because it is based upon assumptions that are sometimes absurd and sometimes self-contradicting."
Does the Whelan Method Work?
Judging the accuracy of Whelan's book is difficult in part because fewer couples use her approach. And Shettles isn't the only person to critique his rival. Madeleine states that after reading both books, "Whelan made no scientific sense to me so we went with Shettles."
