Which is the best time to conceive a boy?
According to Shettles, timing sex as close to or even after ovulation is the key to sway for a boy.

Can a male produce a child?
Men can produce sperm from puberty to a ripe old age and continue to father children as long as they do so. Women, on the other hand, have a limited fertile window. Past 51 – the average age of menopause – they cease to release any eggs and become infertile. Both men and women are delaying having children.
What makes a baby a male?
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.
Which parent determines a child’s gender?
The mother gives an X chromosome to the child. The father may contribute an X or a Y. The chromosome from the father determines if the baby is born as male or female.
How does sperm determine the gender of a child?
These are known as the sex chromosomes. Every egg has an X sex chromosome; a sperm can have either an X or a Y sex chromosome. If the sperm that fertilizes an egg has an X chromosome, the baby is female; if it has a Y chromosome, the baby will be a boy.
Can a 12 years old boy get a girl pregnant?

How does a baby boy reproduce?
When a baby boy is born, he has all the parts of his reproductive system in place, but it isn’t until puberty that he is able to reproduce.

What determines the sex of a man’s child?
The Newcastle University study suggests that an as-yet undiscovered gene controls whether a man’s sperm contains more X or more Y chromosomes, which affects the sex of his children. On a larger scale, the number of men with more X sperm compared to the number of men with more Y sperm affects the sex ratio of children born each year.
When do boys have a growth spurt?
