From a biological perspective, female contraception is illogical. If a woman's method of contraception merely blocks the one egg released each month, then a man producing tens of thousands of sperm daily that travel far and wide is more likely to cause pregnancy and thus requires more stringent prevention. Moreover, given the current social structure, a man's contraceptive effect likely extends beyond just one couple.
In terms of drug-based contraception, it is easier to conceive of and implement for women. Currently, the goal can be achieved by altering the female hormonal secretion cycle to prevent ovulation. However, it seems very difficult to develop a drug that can kill hundreds of millions of sperm in men without side effects and still restore fertility after discontinuation. Nevertheless, many scientists, both past and present, have persisted in their efforts in this direction. Various strange contraceptive methods
In ancient medicine, prescriptions for contraception derived from food experiences were also the source of inspiration for modern contraceptive pills. For example, American Indians were the first to use gromwell for contraception. Later research revealed that gromwell acid contains at least three substances that can inhibit the activity of gonadotropic hormones and the development of sexual organs in mice. Another example is the use of Indian wild peas: when fed to male and female rats, they produced no offspring. After extraction, it was found that the intermediate compound, dimethylhydroquinone, when given to women on the sixteenth and twenty-first days of their menstrual cycle (300-350 mg each time), reduced fertility by 50-60%. When taken by men, it reduced their sperm count by 50%.
In addition, there are many biologically active plants with contraceptive effects, whose active ingredients are not yet fully understood. For instance, extracts from wild banana seeds have been experimentally proven to have anti-implantation and anti-gonadotropic effects in mice, rats, and rabbits. In our country, folk food items like rapeseed, the purple flowers of solanaceous plants (eggplant), and dried and ground calyces from persimmons are all used for contraception. Other traditional Chinese medicines such as white peony, angelica, ligusticum, and rehmannia root are also decocted and consumed for this purpose. Can eating celery make men infertile?
Dr. Bochari, a female physician from the Physiology Department of Siriraj Hospital in Thailand, conducted a ten-year study and found that celery, a common and harmless food, can reduce the number of sperm in men. She conducted experiments on healthy, fertile males aged 18 to 20. After having them eat 75 grams (about two to three stalks) of celery, raw or cooked, daily for one to two consecutive weeks, their sperm count decreased significantly to a level that made conception difficult. This condition returned to normal sixteen weeks after they stopped eating celery. However, this study still lacks more precise control experiments.
