Since ancient times, the history of human contraception has been 4000 years. Nowadays, contraceptive methods often take strange measures, including coitus interruptus, Shanghuan, contraceptives and other methods to achieve the purpose of contraception. Ancient culture is interested in modern people, how do they use contraception? Let's take a look at the contraceptive techniques of ancient women who sprayed rice.
The earliest condom: sheep intestines
Ancient people used sheep intestines as condoms. This is clearly close to modern condoms. The oldest known condom is made of pig intestines, with one end sealed with thread and the other end opening that can be tightened to prevent slipping. The relevant user manual indicates that this type of condom is difficult to use immediately when necessary. Because it is necessary to soak the condom overnight with warm milk for use.
The victim's lead and molten iron
The ancient Greeks believed that molten iron could also be used as a contraceptive tool. Although we don't know who invented this method, it is a fact that lead is present in molten iron. During World War I, the proportion of women working in lead-containing factories suffering from infertility was abnormally high. Scientific research has found that drinking iron can cause neuropathy, kidney failure, coma, and even death. Its effect seems similar to mercury.
Small amount of watermark for contraception
More than 2000 years ago, Chinese women added a small amount of mercury to their tea or daily food for contraception, which is said to have good effects. Modern scientific research shows that a large amount of mercury can lead to death, but a small amount can kill the fetus in the womb. Mercury can cause menstrual disorders, brain damage, kidney failure, and infertility in women.
Cruel uterine cover
The use of expensive materials such as gold, silver, and ivory for contraception may sound great, but it is actually very cruel. Thousands of years ago, people made "uterine sleeves" based on the shape of a woman's uterus. Rich and wealthy families could use materials such as gold, silver, or ivory to make them, and then wrap them in oil paper or beeswax. Obviously, these things sound terrifying, and this contraceptive device is later referred to as a tool for tormenting women. Sometimes, these things can cause toxic shock in women, and the body can emit various odors, causing infections, but they have little effect on contraception.
