Calcium and magnesium rich foods
Examples of foods high on the 'girl friendly' list include cheese, milk, butter, nuts and beans. While foods such as bananas and potatoes should be avoided as they are considered more 'boy friendly'.
You should have sex two to four days before ovulation if you're hoping to conceive a girl. You should avoid intercourse when you have clear, egg white-like vaginal mucus, as this is a sure sign of ovulation. Avoiding intercourse during this time can reduce your likelihood of conceiving at all.
The ratio of male to female births, called the sex ratio, is about 105 to 100, according to the World Health Organization (WHO).
Dr Michael Thomas MD (fertility specialist) actually advises that there are no methods to affect the sex of your child, including sexual position.
The Whelan Method
For a girl, a couple should have sex two or three days before ovulation or on the day of ovulation to increase their odds of having a girl. According to Whelan, the success rate of having a girl with this method is 57 percent.
They found that the most fertile months for conceiving a boy were from September to November, while the lowest fertile period was from March to May.
Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy (XY).
We might expect that naturally an equal number of boys and girls are born, but this is not the case. There are biological reasons why more boys than girls are born each year: around 105 boys per 100 girls. But in countries with a strong son preference, the sex ratio is even more skewed.
All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.
The genetics of height
If they are tall or short, then your own height is said to end up somewhere based on the average heights between your two parents. Genes aren't the sole predictor of a person's height. In some instances, a child might be much taller than their parents and other relatives.
And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
Women around the world report higher levels of life satisfaction than men, but at the same time report more daily stress. And while this finding holds across countries on average, it does not hold in countries where gender rights are compromised, as in much of the Middle East and sub-Saharan Africa.
Yet women continue to live longer than men, suggesting the biological differences also have a role. According to the U.S. Centers for Disease Control, the average American man will live to age 76, while the average woman in America will live to age 81.
Male births were much more likely to require the use of oxytocin, a hormone which stimulates contractions. "Of the women carrying male infants, 70 per cent of them had completely normal deliveries, compared to 76 per cent of females."
The least common birthday is leap day, or February 29. But because the day only occurs once every four years, it's obvious it would yield the least amount of birthdays. The rarest birthday of the 365 annual calendar days is Christmas day, Dec. 25.
A new study has revealed that people born in April are the sexiest - and having a birthday in April myself, I'm obviously completely sold on the theory…
A study done in the U.K. showed that May is the luckiest month to be born, and October is the unluckiest. It could have something to do with that optimism, since positive attitudes have been associated with greater resilience.
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.
