- A baby’s gender is determined when the egg is fertilized.
- Whether a baby will be a boy or a girl is determined at the time of conception, long before most women even realize they are pregnant.
- Both the egg from the mother and the sperm from the father carry sex chromosomes. The egg always contributes an X chromosome, and the sperm can contribute either an X or a Y chromosome, depending on the sperm cell.
- The sex of the baby is determined by the sperm cell that fertilizes the egg first. If the sperm is carrying an X chromosome, the baby will be a girl. If the sperm is carrying a Y chromosome, the baby will be a boy.
- Ultrasounds were not designed for sex prediction.
For some people, waiting until the 18th week of pregnancy to find out the sex of a baby can feel like an eternity. To fill the void, people may turn to some of the following six old wives’ tales to predict whether the fetus is a boy or girl.
Old wives’ tales are fun but generally not reliable for predicting sex.
Baby bump: One popular belief is that if a woman is carrying the baby high, she is supposedly having a girl, while carrying the baby low means it’s a boy.
Food cravings: Another theory holds that a mother’s food cravings during pregnancy may reveal the baby’s sex, with sweet cravings signifying a girl and cravings for salty, sour or odd foods linked with a boy.
Fetal heart rate: There may be some truth to the idea that fetal heart rate could be a clue. Early in pregnancy, there is no difference in heart rate between the sexes. But by the third trimester, a girl’s heartbeat tends to be a little faster and a boy’s a little slower.
Morning sickness: Folk wisdom has linked experiencing severe morning sickness with having a girl, and this idea may have some science to back it up. Women carrying girls have higher levels of the pregnancy hormone hCG (human chorionic gonadotropin), and these higher levels are associated with an increased risk of severe morning sickness.
Ring test: To try this old favorite, a woman ties her wedding band to a string and hangs it over her pregnant belly to guess the baby’s gender. If the ring swings back and forth, the baby is believed to be a boy. If it swings in a circle, the child is thought to be a girl. It’s fun, but it isn’t science.
Hair growth: This has got some relationship to the sex hormones, androgen. So in case of male baby hair growth is more and less in case of female.
Clearly, these tales don’t have any scientific evidence. Keep guessing the sex . Day will reveal the sex of the baby when born.Till then enjoy your pregnancy.
