There is an important relationship between food and human fertility function. Both traditional and modern medicine agree that choosing meals with special effects is good for fertility, while some foods are not good for fertility. Coffee Coffee contains caffeine. A small amount of caffeine can increase sperm motility, but a large amount of caffeine can damage sperm, therefore, men should not drink a lot of coffee. Sunflower The protein part of sunflower seeds contains ingredients that inhibit spermatogenesis in the testes, which can cause testicular atrophy and affect normal reproductive function, so young men of childbearing age should not eat more. Fatty foods Fatty foods such as barbecue, roast goose, sausage and bacon will affect male fertility and make them less likely to be in love, so young people of childbearing age should not eat more. Garlic Garlic has the obvious effect of killing sperm, young people of childbearing age, such as eating too much, has a negative impact on fertility, so should not be eaten. Crude cottonseed oil Crude cottonseed oil contains cotton phenol, long-term consumption of crude cottonseed oil can lead to testicular atrophy, resulting in irreversible spermatogenesis inhibition and infertility. Experimental studies have shown that rats consume feed containing crude cotton seed oil for about 4 months, testes shrink significantly, spermatogenic cells significantly reduced or even disappeared. Adult men taking crude cottonseed oil extract (cotton phenol) 40 days, 60 ~ 70 mg per day, short-term sperm all killed, and gradually disappeared from the semen and caused azoospermia, so men should not eat. Celery Men eat more celery will inhibit the production of testosterone, spermicidal effect, will reduce the number of spermatozoa. It has been reported that some foreign doctors have found after experiments that after eating celery for many days in a row, the number of sperms will be significantly reduced and even to the extent that it is difficult to conceive, but it will return to normal in a few months after stopping eating it. Soy Certain components in soy can cause a drop in sperm count, which can affect male reproductive function. Researchers believe that the chemicals in soy can “mimic” the function of estrogen, leading to reduced sperm counts.
