To father a child, the male partner needs to have healthy sperms. The sperm is produced in the two testicles or testes. This process starts at puberty. Men can produce an average of sperm per second. This means if a man is fertile, he will never run out of healthy sperms.

Sperm cells cannot survive for long once they are exposed to the air outside of the body. Precisely how long they can survive depends on the environment that they are released into and how quickly the fluid surrounding the sperm cells dries up.
Despite most parents ultimately just wishing for a healthy baby, there are many cultural and social factors that can drive the desire for a baby of a particular sex. The medical technology for sex selection of embryos has existed in Australia for many years, but such an option is only available for medical reasons, such as sex-linked chromosomal disorder. This leaves parents who do have a gender preference looking for natural ways of predetermining the sex of their baby.
Sperm gets ejected from the penis, enters the vagina, and swims up the reproductive tract until they reach the egg to fertilize it. Barely years ago, it was considered a major scientific breakthrough when scientists came up with the idea that a fully formed, tiny human inhabited the head of each sperm — totally debunked and untrue. Fortunately, as the human body has evolved over thousands of years to maximize fertility potential, so has our scientific understanding about sperm.
