    Apart from health reasons, I cannot see how this is ethical. This practice is banned by the government.

          Oh I have never heard of that before. Any such practices? I thought that would be more dependent on the father since it's the chromosomes of his sperm that makes the difference.

            I've seen this topic, well somehow it's related; being discussed on local TV few months ago. It was about GENETIC TESTING AND GENETICS RESEARCH which public dissussion are welcome to be lodged to this site Here are what the Bioethic Advisory Committe has recomended ( in particular recommendation 11).
            I have no idea what's the final legislation or if it has been decided. It may be very well like what Aphrael as mentioned.

            For what I've gathered from the talk on TV, according to the guest lawyer; even if this is ban in SG, couple may very well seek treatment in a foreign land which they will not be found guilty.

            OK, that aside... I've heard of dieting method, but have no idea what's inside this "special diet". Some doctors oversea have used this method on couples who suffer from genetic disease expressed in male offspring. I've heard of successful cases.

                I read this topic from MSN Family:

                Can we choose the sex of our child?
                Yes, choosing the sex of your child is technically possible thanks to advances in fertility treatments that allow doctors to create or identify embryos of a certain sex. But today's sex-selection options aren't equally effective, affordable, or available.

                The most accurate sex-selection methods are usually the most expensive (tens of thousands of dollars), often involving invasive infertility treatments and fertility drugs with side effects. If you're serious about trying one of these techniques, you'll have to meet strict eligibility requirements, too. In some cases you won't be eligible unless you're married and already have at least one child of the sex opposite from the one you're trying for. Some clinics also have age limits or require you to take hormone tests to prove you're not approaching menopause.

                And keep in mind that Mother Nature has already tipped the odds a bit in favor of boys in the sex-selection game. According to data released in 2004 from the National Center for Health Statistics, approximately 1,050 boys are born for every 1,000 girls.

                Read on for more information on how today's sex-selection methods work, whether you're eligible to try them, and how much they cost.

                Overview: High-tech sex-selection techniques
                The following gender-selection methods draw from two existing infertility treatments: in vitro fertilization (IVF) and artificial insemination (AI). IVF starts with a round of fertility drugs to stimulate your ovaries to produce several eggs for fertilization, instead of the single egg you normally release each month. Fertility drugs may also be used for AI. For AI, also known as intrauterine insemination (IUI), your doctor uses a catheter to insert a concentrated sperm sample directly into your uterus.

                For IVF, fertilization occurs outside your body (in vitro means literally in glass). Your doctor gives you an anesthetic and removes your eggs from your ovaries by inserting a needle through your vaginal wall. Your eggs are then fertilized with sperm in a petri dish. Two to five days later your doctor places the fertilized eggs ? now embryos ? in your uterus by inserting a thin catheter through your cervix. The number of embryos inserted depends on your age, the quality of the embryos, and your reproductive history. As a general rule, if you're under 35 and the embryos look healthy, no more than two are transferred.

                Preimplantation genetic diagnosis (PGD)
                What it is
                An in vitro fertilization (IVF) technique in which embryos are created outside the womb and then tested for genetic disorders and gender.

                When PGD was introduced back in 1989, it was used solely to help couples or individuals with serious genetic disorders reduce their risk of having a child who suffered from the same condition. Today PGD is still used for this reason, but is also used commonly when women are 35 or older and/or have a history of recurrent miscarriage. Only a handful of clinics offer the technique for sex selection for nonmedical reasons.

                Effectiveness
                Almost 100 percent effective.

                How it's done
                During an IVF cycle, eggs are fertilized with sperm in a petri dish. A single cell or cells are later removed from each of the resulting 3- to 5-day-old embryos and tested for gender.

                In a regular IVF cycle scientists try to determine which embryos are normal merely by looking at them under a microscope. But with PGD, the embryos are tested thoroughly for genetic abnormalities and sex. By transferring only healthy embryos to the uterus, you're less likely to miscarry or have a child with a genetic disorder. Prenatal tests such as amniocentesis or chorionic villus sampling (CVS) are still recommended if you're 35 or older because more genetic abnormalities can be detected later in pregnancy.

                In a regular IVF cycle, doctors usually transfer two or more embryos to your uterus ? the number depends on your age, the quality of the embryos, and your reproductive history. (If you're 40 or older, typically four or five embryos may be transferred.) But in PGD, doctors transfer no more than two because they've already weeded out embryos that are unlikely to implant or to result in a healthy pregnancy.

                Pros
                ? If you do get pregnant, PGD guarantees with almost 100 percent certainty that you'll have a baby of your desired gender.

                Following a PGD cycle, remaining embryos of the selected gender are automatically frozen. These can used in another attempt, if you miscarry or decide you want more children down the road. Frozen embryo transfers aren't as successful as fresh transfers, but the procedure is less invasive and significantly cheaper.

                Cons

                ? A single round of PGD can cost nearly $20,000.

                ? The procedure is invasive and the removal of eggs from your ovaries can be painful.

                ? The fertility drugs you have to take can have uncomfortable side effects such as weight gain, bloating, swelling, and blurred vision.

                ? As with any IVF pregnancy, you're more likely to have multiple births. According to the latest statistics from the Centers for Disease Control and Prevention, 38 percent of infants conceived as a result of IVF and related procedures were twins.

                ? About 43% of fresh IVF cycles result in a live birth, and that figure goes down as you get older. But some doctors claim higher success rates with PGD because defective embryos are excluded.

                ? You'll need to decide what to do with the embryos of the undesired gender: freeze, destroy, or donate for other couples or research.

                Cost
                IVF cycles cost an average of $12,400. PGD adds an additional $3,000 to $6,000-plus to the tab. Check with your medical insurance company ? part of the expense may be covered.

                Availability
                Most fertility clinics that provide PGD don't allow it to be used solely for sex selection. You must have a medical reason such as a family history of genetic diseases or repeat miscarriages, or be over a certain age, usually about 38, to qualify for the procedure.

                That said, a few centers allow you to use PGD to choose the sex of your baby even if you don't have a medical reason to do so:

                ? Genetics and IVF Institute, with facilities in Virginia and Maryland. (To qualify, couples must be married, have at least one child, and desire a child of the opposite gender.)

                ? The Sher Institutes for Reproductive Medicine, with seven branches nationwide. (Prospective patients are screened on a case-by-case basis, and couples with no children are not excluded from consideration.)

                ? Reproductive Specialty Center in Newport Beach, California (restricted to couples who have at least one child and desire a child of the opposite gender).

                For more information
                Read the American Society for Reproductive Medicine's report on sex selection and recommendations for its use.

                MicroSort
                What it is
                A dye technique that attempts to segregate girl-producing sperm from the boy-producing variety. Sperm of the desired gender is inserted directly into your uterus, usually via artificial insemination (AI).

                Effectiveness
                The method is about 90 percent successful when it comes to choosing girls and about 74 percent successful for boys. These rates are per pregnancy, not per cycle.

                How it's done
                MicroSort is based on the premise that girl-producing sperm, which carry X chromosomes, are bigger than the boy-producing sperm, which carry Y chromosomes. The procedure involves coloring a sperm sample with fluorescent dye and then zapping it with a laser that illuminates the dye. The bigger X chromosomes absorb more dye and glow brighter than the Y ones. Sperm are then sorted by supposed gender and the preferred sex is transferred to the uterus, usually via AI. In some cases in vitro fertilization (IVF) is used ? which may increase the likelihood of a pregnancy but is also more invasive and expensive.

                Pros


                ? Artificial insemination poses virtually no health risks and is cheaper than IVF. But you may have to take fertility drugs, which can cause side effects and increase your chances of having multiples.

                ? Because the method typically uses AI instead of IVF, you don't have to worry about what to do with extra embryos.

                ? MicroSort can also be used to try and prevent the transmission of X-linked disorders ? diseases that moms carry and can transfer to boy babies but not girls, such as hemophilia and Duchenne's muscular dystrophy. It lowers the risk of transmitting these disorders but isn't 100 percent effective.

                Cons


                ? The procedure is still being tested in clinical trials and hasn't been approved by the Food and Drug Administration.

                ? Since MicroSort is relatively new (it's been available since 1995 and as of January 2004, more than 500 pregnancies had been achieved), little is known about possible risks.

                ? MicroSort can't guarantee a specific gender because the technology doesn't completely exclude sperm of the unwanted sex.

                ? The pregnancy rate for each artificial insemination cycle is modest ? 16.6 percent. With IVF, the pregnancy rate is 43 percent.

                Cost
                Approximately $3,000 per treatment cycle if AI is used. Fertility drugs can increase the cost by another $2,000. IVF adds an average $12,400 to the cost of each cycle.

                Availability
                To qualify for MicroSort's program, you must be married and have at least one child and want a child of the opposite gender. You, or your egg donor, must be 39 or younger.

                There are two MicroSort centers: The Genetics and IVF Institute has a MicroSort clinic in Fairfax, Virginia. Telephone: (800) 277-6607. The second clinic is in Laguna Hills, California, and operates in partnership with the Huntington Reproductive Center. Telephone: (866) 472-4483.

                MicroSort patients who opt for AI must undergo the procedure at one of these two facilities. But if MicroSort is carried out with IVF or PGD, sperm samples can be processed at one of the labs and then shipped to a collaborating medical facility. If you're interested in exploring that option, talk to your doctor.

                Ericsson
                What it is
                A technique that aims to separate faster-swimming boy-producing sperm from slower-swimming girl-producing sperm. Sperm of the desired gender are inserted directly into your uterus via artificial insemination (AI).

                Effectiveness
                Ericsson claims his technique is 78 to 85% effective when it comes to choosing boys and 73 to 75% effective for girl babies.

                How it's done
                This technique, which has been around since the '70s, attempts to separate boy and girl sperm by pouring a sperm sample on a gluey layer of fluid in a test tube. All the sperm naturally swim down, but the boys tend to swim faster and reach the bottom earlier. Once the fast and slow swimmers are separated, you're inseminated with the sperm that will enable you to conceive the gender you desire.

                Pros

                ? Inexpensive compared to higher-tech methods.

                ? Noninvasive.

                ? Relatively safe.

                Cons

                ? There's no guarantee of success. The technique's pioneer, Ronald Ericsson, has published extensively and claims a success rate of approximately 75 to 80 percent. But some fertility doctors dispute this figure and say that it's no higher than 50 percent.

                ? AI is not as effective as in vitro fertilization (IVF), and it may take many cycles to achieve a pregnancy, depending on your age and fertility.

                Cost
                Approximately $600 per insemination.

                Availability
                Available to anyone who wants it at clinics in California, Michigan, Texas, Connecticut, Montana, Washington, Florida, New Mexico, Maine, and New York. Find a clinic in your area.

                  Overview: At home techniques

                  These low-tech methods are noninvasive and affordable, and can be done in the privacy of your own home. All you need to do is chart your basal body temperature or test for ovulation using an ovulation predictor kit and time sex accordingly. So what's the catch? Their effectiveness is questionable at best.

                  Shettles method
                  What it is
                  Timed intercourse on specific days of your cycle.

                  Effectiveness
                  Shettles proponents claim the technique is 75 percent effective, but other experts dispute this. Keep in mind that you always have about a 50 percent chance of conceiving the sex you want.

                  How it's done
                  The theory is that sperm bearing Y chromosomes (for boys) move faster but don't live as long as sperm that carry X chromosomes (for girls). So if you want a boy, the Shettles method argues, you should have sex as close as possible to ovulation. If you want a girl, you should have sex two to four days before you ovulate.

                  Pros

                  ? Requires no drugs or invasive medical procedures.

                  ? Free or low cost.

                  ? Relatively safe.

                  Cons

                  ? You must take your basal body temperature every day to figure out when you're ovulating, or use an ovulation prediction kit.

                  ? There's no guarantee of success.

                  Availability
                  Anyone can try it.

                  Whelan method
                  What it is
                  Timed intercourse on specific days of your cycle.

                  Effectiveness
                  Whelan claims her technique is 68 percent effective for boys and 56 percent effective for girls, but many experts dispute this. Keep in mind that you always have a 50 percent chance of conceiving the sex you want.

                  How it's done
                  The Whelan method directly contradicts the Shettles method. The theory here is that biochemical changes that may favor boy-producing sperm occur earlier in a woman's cycle. So if you want a boy, you should have intercourse four to six days before your basal body temperature goes up. If you want a girl you should have sex two to three days before you ovulate.

                  Pros

                  ? Requires no drugs or invasive medical procedures.

                  ? Free or low cost.

                  ? Safe.

                  Cons

                  ? You must take your basal body temperature every day to figure out when you're ovulating, or use an ovulation prediction kit.

                  ? There's no guarantee of success.

                  Availability

                  Sex-selection kits
                  What it is
                  These at-home kits are based on the Shettles theory. Separate girl and boy kits include a thermometer, ovulation predictor test sticks, vitamins, herbal extracts, and douches that are supposedly gender specific.

                  Effectiveness
                  Kit makers claim a 96 percent success rate. But the American Society for Reproductive Medicine tells consumers not to bet on it. Some medical experts go a step further and say the kit maker's claims are without scientific merit.

                  How it's done
                  You track your cycle using the thermometer and ovulation predictor test sticks (which you urinate on). Following the Shettles method, you have intercourse two to four days before ovulation if you want a girl and as close as possible to ovulation if you want a boy. The douche is intended to change the vaginal environment to "influence the chances that either an X-carrying sperm or a Y-carrying sperm will be successful in fertilizing the egg." Vitamins and herbal extracts are also included to supposedly boost your odds of getting the gender of your choice.

                  Pros

                  ? Requires no invasive medical procedures.

                  ? Convenient.

                  Cons

                  ? The success rate claimed by the makers is questionable.

                  ? Expensive

                  Cost $199 for a 30-day kit.

                  Availability
                  Sex-selection kits are available through GenSelect.

                  The bottom line: What do the experts say?
                  High-tech sex-selection methods have stirred hot debate in the medical community. Some doctors think it's a great way to balance families, while others think we're heading down a slippery slope. Mark Sauer, a fertility specialist and the program director at the Center for Women's Reproductive Care at Columbia University in New York, thinks that sex selection for family balancing is unethical and has no place in fertility treatments. "I can't endorse the destruction of normal human embryos because they happened to be of the wrong sex," he says. (According to one recent report, four of MicroSort's 500 pregnancies have been terminated for that reason).

                  Not all fertility doctors agree with Sauer. While the American Society for Reproductive Medicine officially opposes PGD for nonmedical reasons, it acknowledges that sex selection shouldn't be condemned in all cases, and doesn't favor making it illegal.

                  Low-tech sex selection has not sparked the same controversy, probably because these methods are far from foolproof and the assumption is that couples practicing them are investing less ? both financially and emotionally ? in their success. But do they work?

                  These techniques range from Shettles and Whelan to folk wisdom such as making love standing up and eating more meat if you want a boy, and eating lots of chocolate and having sex in the missionary position if you want a girl.

                  "I tell my patients that if they want to try low-tech methods, give them a go," says Brian Acacio, a fertility specialist and medical director of the Sher Institutes of Reproductive Medicine (SIRM) in Los Angeles. "They probably won't hurt, and there's a 50 percent chance they'll work."

                    IMO i think the Shettles method is the logical, easier and less expensive way...but we have to be very sure of our ovulation period...

                      The most certain method is still using IVF. IMHO any other methods only increase the chance by a tiny little bit, which is not much difference from doing nothing at all.

                      In this day and age, having a girl is actually better than having a boy. When a boy gets married, they will only listen to the wife. If you dare say anything, you will be labelled a "monster-in-law" and will be thoroughly hated. Nowadays, a woman is able to earn as much as a man. The managing director of IBM Singapore is a woman. There are many women who are highly-paid professionals like doctors and lawyers. I don't understand why is there still so much prejudice ?

                      When I was carrying my first baby, a girl, people will give me the sympathetic look or try to console me. When I was pregnant with my son, people will say "You must be so happy now that you have a son", I actually felt offended, because it is so unfair for my daughter.

                        Look, in this day and age, I go out and people still ask my parents whether we have a boy in the family (not counting my father). There are only two girls in the family - me and my sister. That's very offensive. My parents really don't care as long as we're healthy and live a wholesome life. Why do people even care what's happening in other people's families? It's fun to have a little boy running around, but I find little girls much sweeter.

                        If you want to try for a boy for whatever reason, the Shettle method does sound logical. My lewd anatomy lecturer used to insist it works - he has 5 boys at home. I wouldn't bet on it though. It just takes 1 sperm to fertilize an egg. But whatever you get, I hope you treat him/her fairly.

                              Well, as mothers, of cos as long as our child is healthy and happy, that's what most important, irregardless of gender. But for people like me, when I've already have a girl, so naturally I'll hope that my next child will be a boy, so as we'll have one boy and one girl. If there are convenient non-invasive methods that we can try at home, eg to eat more fish in our diet, then I'll think why not give it a try? I don't think this is a prejudice or biased, cos I dare say I love my daughter so much, and if mother nature wants me to have another girl again, I'll love her as much as my first one too.
