Ejaculated sperm remain viable for several days within a woman's reproductive tract or in nutritive liquid culture medium in a lab setting. Fertilization is possible as long as the sperm remain alive — at least five days. Mayo Clinic does not endorse companies or products.

So it all comes down to the banana. The yellow fruit with the phallic shape — appropriate in this context — is the best dietary aid for intending mothers wanting a boy, according to research published yesterday. In what they claim is the first scientific evidence that diet influences infant gender, researchers at the Universities of Exeter and Oxford have found that women who consume more calories around the time of conception, and, in particular, eat more bananas, are more likely to have sons.

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.

Super swimmers. The ability of Y-chromosome sperm to swim faster than their X-chromosome counterparts may explain why longer attempts at pregnancy result in more boys than girls. For women hoping to conceive boys, there's an upshot to having a hard time getting pregnant.

Sperm is half of what begins all human life and ensures our survival as a species by helping to populate the Earth. The importance of sperm is taken for granted because a man literally generates millions of them each day, and just one ejaculation can release approximatelysperm, but only a mere of them survive to reach the ovum. The amount of time that sperm can live inside of a man varies depending upon the quality of the specimen, but on average they can survive stored in the testicles for up to 74 days.

Whether your baby is a boy or a girl is determined by the chromosome it inherits from its father. The egg from its mother always contains an X female chromosome, but the sperm contains either a female or a Y male chromosome. When the egg is fertilized the chromosomes come together and if they are XY a baby boy is conceived and if they are XX a baby girl is conceived.

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.
