Nature is designed to favour the conception of boys from September to November and girls from March to May because of an evolutionary mechanism aimed at keeping the overall sex ratio as near to 50:50 as possible, the scientists said.
Because male sperm is the faster of the two, Shettles suggests having intercourse as close to ovulation as possible, so the male y sperm can reach the egg first. If you have sex several days before the day of ovulation, the less resilient male sperm may die off. This leaves more female sperm to fertilize the ovum (5).
The key to conceiving a boy is to do “the deed” close to your ovulation. As Dr Shettles points out, male-producing sperm (Y-chromosome) move faster than female sperm. Male sperm also dies pretty fast, while female-producing sperm (X-chromosome) can stick it out and take their time hooking up with the egg.
High potassium foods might increase your chances of conceiving a boy. Potassium is an essential nutrient that plays a crucial role in your health. Bananas, salmon, and avocado are all foods that contain potassium. Other foods that contain potassium include dried fruits, legumes, potatoes, winter squash, and broccoli.
Walnuts, in particular, may help boost sperm quality. That's because walnuts are packed with antioxidants and omega-3 fatty acids. Other antioxidant-rich nuts include almonds, pecans, pine nuts and hazelnuts.
Researchers surveyed 740 women during their first pregnancy and found that those with a diet high in potassium (one of the main vitamins in bananas) were more likely to have a boy.
“What we have been taught conventionally is that—bar any genetic disorders that cause early pregnancy loss that only affect girls or boys—there is always a 50/50 chance of one or the other gender each time. The chance of a girl after three boys is still the same probability.”
Almost everyone has around a 50% chance of having a boy and a 50% chance of having a girl. What we can say is that dad's sperm determines whether a baby will be born as a boy or a girl. About half of his sperm will make a boy and half a girl. The sex of the baby depends on which sperm gets to the egg first.
Fertility treatment
Some fertility drugs work by stimulating a woman's ovaries, which can sometimes cause them to release more than one egg. If sperm fertilizes both of these eggs, this can result in twins. In vitro fertilization (IVF) can also increase the chance of conceiving twins.
Morning may be the best time to have sex for conception, at least as far as sperm are concerned. Some studies have suggested that sperm count and quality are slightly higher early in the morning, which may mean better odds of conception if they're deposited right after a good night's sleep.
Pregnant women carrying girls have a greater chance of experiencing nausea and fatigue, according to the results of a study from the USA's Ohio State University Wexner Medical Center.
For a boy, sperm with the Y chromosome should be deposited as close as possible to the egg because the Y chromosome has a short lifespan and it will not live longer than 24 hours, compared with the sperm with the Y chromosome which will live in a woman's body for up to 72 hours.
It's all about Dad's genes
A man's X and a woman's X combine to become a girl, and a man's Y combines with a woman's X to become a boy. But if the sperm don't have equal Xs and Ys, or if other genetic factors are at play, it can affect the sex ratio.
The father has one X chromosome and one Y chromosome, can give either his X or Y chromosome. The egg (from the mother) already contains an X chromosome. Therefore the sex of a baby is determined by the X or Y chromosome of the sperm cell from the father.
No, you can't influence the sex of your baby. Most studies show that males produce and release sperm fairly evenly, as in a 1:1 ratio of X chromosomes and Y chromosomes. This means that the chances of having a girl vs. a boy will be about 50:50.
The X and Y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual: females inherit an X chromosome from the father for a XX genotype, while males inherit a Y chromosome from the father for a XY genotype (mothers only pass on X chromosomes).
If you have two children, you'll have a 50% chance of having a second boy, based on the ratios above. Then if you have three children, you'll have a 25% chance of having all three boys, and a 75% chance of two girls and a boy or two boys and a girl.
Biological sex in healthy humans is determined by the presence of the sex chromosomes in the genetic code: two X chromosomes (XX) makes a girl, whereas an X and a Y chromosome (XY) makes a boy. In this way, it is the presence or absence of the Y chromosome in a healthy human that differentiates boy from girl.
Protein is needed for growth and to support the development of the developing baby. Good sources include lean meat, chicken, seafood, dairy products, nuts, eggs and legumes, including baked beans, chickpeas, lentil and kidney beans. Fibre helps prevent constipation.
The National Institutes of Health recommends for pregnant women to eat three to four servings of banana every day. Here are some benefits of this delicious fruit for pregnant women: Good source of calcium…
Avoid eating dairy foods such as milk, cheese, yoghurt and ice-cream. Eat more foods which contain potassium such as bananas, broccoli, potatoes, spinach and brussel sprouts. Some researchers believe that taking a daily supplement of Evening Primrose Oil boosts the chances of conceiving a boy.
General tips to help conceive a boy
Caffeine may help to give the Y-laden sperm an additional boost. An energy drink, cup of coffee or even some chocolate before having sex won't do any harm.
