Will the baby be a Boy or Girl ?

girl
 
At conception, gender is determined by chromosome characteristics - and it will be the male
(or rather the male's sperm) 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 a Boy ? 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 the decreased life span of the 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 a Girl ? 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 want - a girl. You know you ovulate 14 days into your cycle. You must deliver sperm no earlier 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. 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.

Old wives tales

 
There are many old wives tales out there as to how to ensure that your baby is either a boy or a girl. Some are well, a little odd, and some seem as though they may have a bit of truth to them. There is also some which are based on medical fact, but just how true they are we do not know for sure.

Your baby is what you eat
If you want a boy:
  • Eat red meat.

Old wives tales and Sex

 
If you want a boy:
  • The woman should stay horizontal after sex, as this gives the boy sperms a better chance of reaching the cervix that the girl sperms.
  • Make love standing up, or use the rear entry position.
  • Focus on the males pleasure during love making.
If you want a girl:
  • Make love in the missionary position, or with the woman on top.
  • Focus on the female's sexual pleasure.
Other old wives tales on determining the sex of your baby include:
  • Make love on a quarter moon if you want a boy.
  • Make love on a full moon if you want a girl.
  • Make love on odd days for boys and even days for girls.
  • The more dominant sex in the relationship will produce offspring of the same sex.
