You can choose your baby's gender ('xes') before conception

At conception, gender is determined by chromosome characteristics - and it will be the male (hubby) that dictates whether the baby will be a boy or a girl.

Prior to conception, the unfertilized egg carries an X chromosome while the sperm can carry either an X or a Y chromosome. The gender of the baby comes down to one simple event:

• If the sperm carrying an X chromosome fertilizes the egg, a girl will be conceived.
• If the sperm carrying a Y chromosome fertilizes the egg, a boy will be conceived

Timing of Intercourse

Studies indicate that the sperm with the X chromosome - or female chromosome - have a longer life span than the male sperm (with the Y chromosome). Yet the male sperm appear to have a higher motility. Sperm motility is measured in two ways: percentage of sperm exhibiting movement, and the quality of this movement, which is called the forward progression. Poor motility means the sperm have a difficult time swimming toward the egg. It is said that the sperm carrying the Y chromosome uses energy faster than the sperm carrying the X chromosome. The energy utilization is said to be due to the speed in which sperm swim. Supposedly, the Y sperm is speedy or contains less mitochondria whereas the X sperm is slower or carries more mitochondria. Mitochondria are the energy producing cellular components which are absolutely necessary for life. Sperm contain, and can only produce, so much fuel for their journey. If one sperm type swims faster than another, the consequence of that, of course, is faster arrival - but also faster expiration. That said, if a woman knows her cycle and when she ovulates, the odds of baby gender prediction can be in one's favor. Sperm can reach the fallopian tubes in about 20 minutes to 2 hours. Sperm are viable for about 4-7 days inside the woman.

You want to have a Boy ?

It is believed that if intercourse takes place closer to ovulation, then the probability is greater that the child will be male, due to the high motility (forward progression) and also the decreased life span of the Y carrying sperm.  If you want a boy - aim for later intercourse before ovulation - say about 1 day before ovulation. Frequent intercourse around the time of ovulation. Have your partner wear boxers. A male with a high sperm count is more likely to have a boy. You want to have a Girl ?  The sperm with the X chromosome - or female chromosome - have a longer life span than the male sperm, but exhibit decreased motility. Therefore, intercourse that takes place earlier may provide increased probability of a girl.   You know you ovulate 14 days before your next cycle. You must deliver sperm no closer than 4 days before ovulation. This way, the Y carrying sperm will likely be expired and the X carrying sperm still viable. When the egg is released at about 5 days after intercourse, the X carrying sperm will be in the fallopian tube waiting. If an X chromosome sperm fertilizes the egg, a girl will be conceived. The critical and perhaps not so obvious tip - don't repeat intercourse again for a week! Make sure fertilization is with 'mature sperm'. To sum up: If you want a girl - aim for earlier intercourse before ovulation - at least 4 days before you ovulate. 'Xesual' position also matters in the success of baby's gender selection. Parents desiring a girl, are encouraged to have sex in the missionary position (face to face, man on top) about two to four days before ovulation so that by the time the egg comes, only the heartier, more resilient X sperm will remain in the woman's reproductive tract.  Rear entry positions (man enters woman from behind) gives the Y chromosome an advantage over its the  X when the sperm is discharged as close as possible to the opening of the cervix.  Other methods such as Sperm sorting and Preimplantation Genetic Diagnosis (PGD) are most effective, costly but not natural methods .

This is clear enough, right? Wish you luck in your baby's gender selection now and in future.
