Hormone levels in the male parent affect the sex ratio of sperm in humans..

A child’s gender (male or female) is determined by the chromosome that the male parent contributes. Females have XX sex chromosomes. Males have XY sex chromosomes. A male infant results if the male contributes his Y chromosome while a female infant results if he contributes his X chromosome.

What are the chances of having a boy after a girl?
So the chance of one child being a boy or girl is independent of any other child’s gender in the family. It’s just a matter of which type of sperm happens to reach the egg first. In families that have all boys or all girls, it turned out to be the same one each time.
Can you increase your chances of having a girl?
According to this method, to increase the chance of having a girl, you should have intercourse about 2 to 4 days before ovulation. This method is based on the notion that girl sperm is stronger and survives longer than boy sperm in acidic conditions. By the time ovulation occurs, ideally only female sperm will be left.
How do you guarantee a baby boy?
It’s based on the idea that biochemical changes in a woman’s body at certain times in her cycle make it more likely that Y-sperm will fertilize an egg, while other times in her cycle, her biochemistry will favor X-sperm. So to conceive a boy, you should have sex four to six days before ovulation.
What is the gender of YY?
The Y chromosome contains a “male-determining gene,” the SRY gene, that causes testes to form in the embryo and results in development of external and internal male genitalia. If there is a mutation in the SRY gene, the embryo will develop female genitalia despite having XY chromosomes.

Does family history determine baby gender?
“The family tree study showed that whether you’re likely to have a boy or a girl is inherited. We now know that men are more likely to have sons if they have more brothers but are more likely to have daughters if they have more sisters. However, in women, you just can’t predict it,” Mr Gellatly explains.
