Where does the sperm come from?

There are millions of sperm produced by your testicles everyday. Sperm cells undergo the natural cell division which inevitably leads to its maturation. Half of the sperm carries a Y chromosome (inherited from your father) and an X chromosome (inherited from your mother). If a Y-carrying sperm fertilizes the woman's egg, the result is a baby-girl. If on the other hand, it's the X-carrying sperm which fertilized the egg, then it's a baby-boy.

During ejaculation, sperm is pumped into the man's vas deferens where fructose, seminal fluids, and other chemicals are secreted. Your sperm and other seminal fluids (called semen) hurries past the bladder through the urethra and out of your phallus.

In order for the sperm to enter the woman's cervix, you need to experience erection, orgasm, and ejaculation. An erection takes place when your penis is stimulated or when you have an erotic thought. There is a sudden rush of blood to the erectile tissue chambers in your phallus. This engorges the phallus making it hardened, enlarged and elevated.

With continued stimulation, orgasm and ejaculation ensues. Orgasm is a pleasurable emotional or psychological response that accompanies sperm ejaculation.

There are two stages of orgasm:

1. The first one, called the ejaculatory inevitability, takes place two to four seconds before ejaculation. During these crucial seconds, you may be aware that you are about to "come," and you could not do anything to control it. Your seminal vesicles and your prostrate gland begin to throb.

2.The second stage of orgasm takes place when you involuntarily ejaculate semen in convulsive surges. One teaspoon of semen is ejaculated containing 40-150 million sperm! The first squirt contains the largest amount of sperm.

Afterwards, you go through a recovery period where you cannot experience another orgasm. This may last several minutes and sometimes for hours.
