Although people now use condoms for contraception, in ancient times, there was no such thing as a condom. In ancient times, women in the brothel also needed contraception. How did the woman as a brothel have contraception? Knowledge is also very advanced and there are a variety of contraceptive methods. The belly stickers have put the musk into the prostitute’s navel to prevent contraception. For example, Zhao Feiyan and Zhao Hede, the two most famous Chinese “eyes”, have recorded such contraceptive measures. Of course, Zhao Feiyan and Zhao Hede can not be called prostitutes, but they are the same. This kind of navel is called “the belly stick.” Sticking to the navel, you can get pregnant with the concept of pregnancy, and then can not be pregnant, but this “pasta” has been lost. Even if it is a modern society, cold medicine does not have 100% effective contraceptive measures. Wei Xiaobao is the product of contraceptive failure. In the past, many women in the brothel were infertile after a long time. They were long-term drinking of a decoction that destroyed fertility. As a result, they were sterilized. They said that they were taking a contraceptive medicine called “cold medicine” and also contained musk. The ingredients that affect fertility, but not necessarily sterilization. Condoms also have the use of “condoms”, the use of animal casings, it is said to be sheep, and the pig bladder is an early “condom”, but according to historical records, the “condom” used in Western medieval courts. It is the animal’s casing, and there is a very nice name “Netherlands Little Hat.” Chinese ancients also used fish as a “condom.” In the museum’s collection, there are condoms made by ancient people using sheep intestines, which are somewhat close to the prototype of modern condoms. The animal’s feces were used in India and Egypt more than 3,000 years ago, and the droppings of animals thought to have mystical powers such as crocodiles and elephants were also used in contraceptives. In fact, because these animal feces are highly acidic, it does have a certain spermicidal effect. However, the strong smell of animal manure will obviously affect the “sexual interest” of ancient couples. Drinking mercury also takes the method of drinking mercury. Mercury can be used for contraception, but mercury is highly toxic. Maybe it may not drink a small amount of death. Now, in the northern rural areas of our country, many elderly people use the method of drinking mercury contraception when they are young, which is definitely harmful to the body. In the past, the teas or daily foods of the prostitutes were put in a small amount of mercury. It is said that the effect is very good. Of course, the prostitutes are kept in the drums. They think that they are contraceptive incense burners, otherwise the prostitutes know that mercury is poisonous. Don’t dare to drink! Men who drink mercury are prone to become feminine when their voice is thinner and their breasts are enlarged. Such people are prone to male infertility, and even if they are born, the next generation is more likely to be deformed. Women can cause irregular menstruation, amenorrhea, egg variability, no sexual desire or stop ovulation. How about the ancient brothel woman’s contraceptive method is wonderful enough. Males have condoms, which were called “condoms” at the time. They are very thick. After each use, they are washed and rubbed with talcum powder and can be used repeatedly. Others are targeted at women, including uterine caps, infusion contraceptives, contraceptives, and placements like lint or sponge. Uterine cap: made of thin rubber. Before going to the house, put the uterine cap into the vagina and cover the cervix. Before use, apply a spermicidal ointment to the inside, outside, and the edge of the cap. After the house, 8 to 12 hours before taking out the uterine cap, wash it with soap in warm water, dry it, sprinkle with talcum powder, put it in a clean box, use it again next time, no need to disinfect. Take medicine: 10 minutes before the house, put the contraceptive medicine into the deep part of the vagina, take the medicine and see the heat melt, spread on the surface of the cervix and vaginal, can kill the sperm and prevent the sperm from entering the uterus. Ointment: Use a tube (injector) to directly apply the contraceptive ointment to the cervix. After taking the medicine, do not sit up, lest the ointment flow out.
