From a biological perspective, female contraception is illogical. If women's contraception is just blocking one egg that is excreted within a month, then men who produce thousands of sperm every day are more likely to become pregnant and need to be stopped. Moreover, from the current social structure, the contraceptive effect of a man is likely to be more than just that of a couple.
Why can men eat more celery to prevent pregnancy?
Experts have conducted a decade long study and found that celery, which is commonly consumed and harmless, can reduce the number of male sperm insects. Experts conducted experiments on healthy and fertile men aged 18 to 20 years old. After eating 75 grams of celery (about two or three plants) raw or cooked every day for one or two weeks, the sperm count significantly decreased to a point where it was difficult to conceive. This situation returned to normal after 16 weeks of cessation. However, this study lacks more precise control experiments.
Using medication for contraception is easy to think of and achieve for women. Currently, changing the secretion cycle of female hormones and preventing ovulation can achieve contraceptive effects. However, it seems difficult to find a drug that can kill billions of male sperm insects without any side effects and restore fertility after discontinuation. However, there have been many scientists who have not given up on this direction throughout history.
The inspiration for modern contraceptives came from food experience to prescriptions for contraception in ancient medicine. For example, the Native Americans first used purple grass for contraception, and later developed a mixture of at least three substances called purple grass acid, which can inhibit the activity of gonadotropins and the development of sexual organs in mice. For example, after feeding wild Indian peas to both male and female rats without offspring, after extraction, it was found that the intermediate dimethyl hydroquinone was given to women on the 16th and 21st days of the menstrual cycle, with doses ranging from 300 to 350 milligrams per dose, resulting in a 5-60% decrease in fertility; Male sperm count decreases by 50% after taking it.
In addition, there are many bioactive plants with contraceptive effects, and their effective ingredients are not yet clear. For example, wild banana seed extract has been experimentally proven to have anti implantation and anti gonadotropic effects on rats, mice, and rabbits. Chinese folk foods such as rapeseed, purple eggplant flowers from the Solanaceae family, and dried persimmon stems are all widely used for contraception. Other traditional Chinese medicines such as white peony, Angelica sinensis, Chuanxiong, and Shengdi are also boiled and taken for contraception.
