First, the ancient female contraceptive trick used arsenic and other toxic drugs for contraception.
In ancient China, prostitutes used some poisonous drugs in traditional Chinese medicine to prevent pregnancy. For example, the mercury mentioned above, and the use of arsenic or brucine for contraception, although the use of large doses of such drugs will kill people, but the use of small doses can kill the fetus in the abdomen, therefore, prostitutes who take this contraceptive method can not have children for life, often when they first start to be prostitutes, pimps secretly drug them.
Second, the ancient female contraceptive tactics used the method of drinking water and adding silver to contraception.
Mercury can indeed be used for contraception, but mercury is very toxic. Maybe drinking a small amount won't kill you. More than 4,000 years ago, women in China added a small amount of mercury to tea or daily food for contraception, which is said to have a good effect. According to modern scientific research, a large dose of mercury can kill people, but a small dose can kill the fetus in the uterus.
Mercury can cause menstrual disorders, brain damage, renal failure and infertility in women. In the past, prostitutes in brothels put a small amount of mercury into their tea or daily food. It is said that the effect is very good. Of course, prostitutes are kept in the dark and think that it is incense burner ash or something that can be used for contraception, otherwise prostitutes know that mercury is toxic and dare not drink it! According to modern scientific research, mercury contraception does make sense.
It is reported that the incidence of menstrual disorders among female workers exposed to mercury vapor for a long time in the working environment is 2 ~ 3 times higher than that of the normal control group. Common symptoms include menorrhagia, prolonged menstrual period and dysmenorrhea. There are also people with too little menstruation and fewer menstrual days. Mercury can cross the placental barrier, leading to miscarriage or premature delivery.
Third, the ancient female contraceptive trick used animal feces to make contraceptives.
The ancient Egyptians were able to create such outstanding works as pyramids and mummies, so it is not surprising that they found a way to control fertility. It is said that the ancient Egyptians believed that crocodiles, elephants and other animals had mysterious powers, so their feces were also used as contraceptives. In fact, because the feces of these animals are highly acidic, they do have a certain spermicidal effect. However, the strong smell brought by animal manure will obviously affect the "sexual interest" of ancient couples.
Fourth, the ancient female contraceptive trick used weasel's testicular leggings for contraception.
From12nd century to15th century, Europe was in a "dark age". Women usually make amulets with small bags containing mule earwax, weasel testicles and black cat bones, and tie them on their legs during sexual intercourse in order to achieve contraceptive effect. Although we now know that these things don't work at all, we can be sure that these things will have psychological effects. Because any man may lose his "sexual interest" when he sees such a pair of things as decorations on his spouse.
