Celery for contraception?

From the biological point of view, women contraception is illogical If a woman's contraception is just to kill an egg discharged in a month, it is easier for a man to produce thousands of spermatozoa every day, and more necessary to stop them And in terms of the current social structure, the contraceptive effect of a man is likely to be more than that of a couple It is easy for women to think of and do contraception with drugs At present, the effect of contraception can be achieved only by changing the cycle of Mongolian secretion of female drugs and preventing ovulation However, it seems difficult to achieve this ideal drug to kill hundreds of millions of male spermatozoa without side effects and restore fertility after drug withdrawal However, there have been many scientists who have not given up their efforts in this direction since ancient times Can eating celery make a man contraception? From food experience to contraceptive prescription in ancient medicine, it is also the source of inspiration for modern contraceptives For example, the American Indians first used Lithospermum for contraception, and later developed a mixture of at least three substances, which can inhibit the activity of gonadotropins and the development of sexual organs in mice Another example is that after feeding the male and female rats with Indian wild peas, they have no offspring After refining, it is found that the intermediate dimethylhydrokun is taken by women on the 16th and 21st day of menstrual cycle, 300-350 mg per time, and the fertility is reduced by 5-60%; the sperm number of men is reduced by 50% In addition, there are many biological active plants with contraceptive effect, whose effective ingredients are not clear, such as the extract of wild banana seed The experiment proves that they have the effect of anti implantation and anti gonadotropic to rats, mice and rabbits Chinese folk food, such as rapeseed, purple eggplant flowers of Solanaceae, persimmon and dried persimmon, are widely used for contraception Other traditional Chinese medicines, such as peony, angelica, Ligusticum chuanxiong and Shengdi, are also used for contraception A decade long study by Dr pocharie, a female physician from the Department of physiology, Surrey hospital in Thailand, found that regular and harmless celery can reduce the number of male spermatozoa She tested healthy and fertile men aged 18 to 20 After giving them seventy-five grams (about two or three strains) of celery raw or cooked every day for one or two weeks, the amount of spermatozoa would be significantly reduced to the level of difficult pregnancy, which would return to normal again ten or six weeks after stopping the dish However, this study lacks more precise control experiments.
