Sexual positions that allow for deep penetration are likely to be the best for conception as they allow the sperm to be deposited as close to the cervix as possible. The missionary position is often recommended for this reason.
It takes just one sperm to fertilize a woman's egg. Keep in mind, though, for each sperm that reaches the egg, there are millions that don't. On average, each time men ejaculate they release nearly 100 million sperm.

The sperm enters the body through the vagina, then travels through the cervix and womb to the fallopian tubes, where the egg is usually fertilised (conception). The egg can be fertilised by sperm contained in semen or pre-ejaculate.
At least 11 million moving sperm are needed in the vagina to achieve a pregnancy even though only one victorious sperm is normally allowed the privilege of fertilizing the egg that was made receptive by the hormonal machinations leading up to and including ovulation.
Your most fertile day, and the day you are most likely to ovulate on, is the last day of egg-white cervical mucus. You can also track your ovulation hormone using at-home ovulation tests (sometimes called an ovulation predictor kit, or OPK).
While September is the most popular month for American couples to start trying to get pregnant, many don't actually conceive until late autumn. If you're trying for a baby this fall, your chances of success are highest in late November and early DecemberOpens a new window.
You're most fertile at the time of ovulation (when an egg is released from your ovaries), which usually occurs 12 to 14 days before your next period starts. This is the time of the month when you're most likely to get pregnant.
It's very unlikely that ejaculate (which contains sperm) could get through several layers of clothing. Pregnancy can happen when ejaculate or pre-ejaculate gets in the vagina or on the vulva.”Dry sex” usually refers to body rubbing between two partners who keep their clothes on.
The required size of the penis to penetrate enough to impregnate is about 4 inches in the erect form. There are lots of misconception with regards to this as to how the size effects reproduction. Using certain positions such as missionary and slow withdrawal can help to a great extent.
No evidence suggests blocking sperm can cause harm or negative side effects. Unejaculated sperm is not harmful to the body and does not build up. The body reabsorbs sperm that does not leave through ejaculation. This has no side effects on sex drive or fertility.
One UK-based study found that laying down for 15 minutes after IUI raised the pregnancy rate to 27% compared to 18% for those that got up immediately following intercourse.
