When it comes to the best position to get pregnant, the general rule is that the male sperm must be deposited as near to the female cervix as possible.,This has something to do with the life spans of the female egg and the male sperm. Once an egg is released from the ovary a stage also known as ovulation - it begins its path down the fallopian tube to the uterus. A released egg typically survives for only 24 hours, while a sperm can last anywhere from three to five days in the female body. As such, the egg has to be as close to the egg as possible so they can meet and join before the egg dies.,While not a lot of people will agree that the sexual positions have anything to do with getting pregnant, the logical inference is that it makes sense to assume the position that can help the sperm meet the egg in the shortest possible time.
