Ancient Contraception Contraception is defines as the deliberate use of artificial methods or other techniques to prevent pregnancy as a consequence of sexual intercourse. The major forms of artificial contraception are barrier methods, of which the most common is the condom; the contraceptive pill, which contains synthetic sex hormones that prevent ovulation in the female; intrauterine devices, such as the coil, which prevent the fertilized ovum from implanting in the uterus; and male or female sterilization. Since ancient Egyptians further than 4,000 years ago, contraception was evident. These women used a tampon made of lint which was moistened with acacia tips ground with honey to avoid pregnancy. Risky and threatening methods were used as well, spongy fabrics with an absorptive trait were inserted into a woman. Another form was the mixture of crocodile dung with paste and then inserting it into a woman's vagina. (The ecology of birth control, 1971) This paved the way for today’s contraceptives.
Sperm and Eggs In 1677 a student of Anton van Leeuwenhoek, a Dutch naturalist, discovered sperm. (Greenburg, J. S., et al.) Scientists first believed they saw "tiny men" called animalcules inside sperm cells. At its introduction sperm was denied by scientists to be possibly responsible for creating human life. The animalcules theory lead to the assumption that the female was a nest for the sperm. Simultaneously scientists who were ovists alleged that the baby was already housed in the female and the sperm solely activated the development of the pregnancy. The conclusion that an egg is entered by a sperm was finalized in 1875. (Where do babies come from?, 1987).
