Birth Control Birth Control Birth Control is defined as various ways used to prevent pregnancy from occurring. Birth Control has been a concern for humans for thousands of years. The first contraception devices were mechanical barriers in the vagina that prevented the male sperm from fertilizing the female egg. Other methods of birth control that were used in the vagina were sea sponges, mixtures of crocodile dung and honey, quinine, rock salt and alum. Birth Control was of interest for a long time, but women did not worry to much about it because child death rates were so high. They felt they needed to have many children just for a few to survive. In the early 1800's death rates began to drop and people began to show concern for controlling births. Early efforts to develop birth control met with resistance from religious leaders and other groups. In 1873, the U.S. Congress passed the Comstock Law, which regulated public access to birth-control devices and information for the next 60 years. This prohibition, which made it illegal to distribute any device, medicine or information designed to prevent conception, applied even to doctors.
