Explanation:

How do women's eggs develop?

For women, a potential pregnancy begins in the ovaries, those two almond-shaped glands attached to either side of the uterus.

Ovaries come fully stocked: You are born with 1 to 2 million eggs – more than a lifetime's supply. The eggs begin dying off almost immediately, and no more are ever produced.

Altogether, you probably release about 400 eggs over the course of your reproductive years, beginning with your first period and ending with menopause (usually between ages 45 and 55).

female reproductive system, including two fallopian tubes, uterus, two ovaries, cervix, and vagina

During the middle of the menstrual cycle, most likely sometime between the 9th and 21st days for women with a 28-day cycle, an egg reaches maturity in one of her two ovaries, then is released and quickly sucked up by the opening of the nearest fallopian tube. These two 4-inch canals lead from the ovaries to the uterus.

This release, called ovulation, starts the conception clock ticking. The egg lives only about 24 hours after ovulation, so it has to be fertilized soon for conception to happen. If your egg meets up with a healthy sperm on its way to the uterus, the two can join and begin the process of creating a new life.

If not, the egg ends its journey at the uterus, where it either dissolves or is absorbed by the body. When pregnancy doesn't occur, the ovary eventually stops making estrogen and progesterone (hormones that help maintain a pregnancy), and the thickened lining of the uterus is shed during your period.

How do men make sperm?

A man's body is almost constantly at work producing millions of microscopic sperm, whose sole purpose is to penetrate an egg. While women are born with all of the eggs they'll ever need, men aren't born with ready-made sperm. They have to be produced on a regular basis, and from start to finish it takes 64 to 72 days for new sperm cells to develop.

male reproductive system, including ureter, seminal vesicle, prostate, urethra, testicle, scrotum, epididymis, penis, and vas deferens

The average sperm lives only a few weeks in a man's body, and about 250 million are released with each ejaculation. That means new sperm are always in production.

Sperm begin developing in the testicles, the two glands in the scrotal sac beneath the penis. ( The testicles hang outside a man's body because they're quite sensitive to temperature.

To produce healthy sperm, testicles have to stay around 94 degrees Fahrenheit – about four degrees cooler than normal body temperature. The sperm are stored in a part of the testicle called the epididymis before mixing with semen just prior to ejaculation.

Despite the millions of sperm produced and released with each ejaculation, only one can fertilize an egg – this is the case even for identical twins. The sex of the resulting embryo depends on which type of sperm burrows into the egg first. Sperm with a Y chromosome make a boy baby, and sperm with an X chromosome make a girl.

Plenty of myths about how to choose a baby's sex have been circulating for centuries. Some are backed by a bit of scientific evidence, but a child's gender is pretty much randomly determined.

Does having an orgasm help baby-making?

Besides being pleasurable, that wonderful sensation known as an orgasm also has an important biological function.

In men, having an orgasm propels sperm-rich semen into the vagina and up against the cervix, helping them reach the fallopian tubes minutes later. This gives sperm a head start on their way to the egg.

A woman's orgasm also might help conception: Some studies suggest that the wavelike contractions associated with the female orgasm pull sperm farther into the cervix (but other research says there's no real evidence this is true).

Still, having an orgasm couldn't hurt – and just might help – your chances of getting pregnant.

Many couples also wonder whether a particular sexual position is best for baby-making. You may have heard that certain positions are the best because they allow for deeper penetration, but there is no evidence that sex position has any effect on pregnancy rates.

But do whatever you like. The most important thing about sex is that you're both having a good time and you're doing it frequently enough to have live sperm in the woman's reproductive tract during ovulation. That means you should aim to make love at least every other day during the middle of your cycle.
