1、 Excessive or insufficient nutrition
Nutritional factors are closely related to fertility, which has been confirmed by scientific research. Undernutrition or overnutrition can lead to male infertility. Animal experiments have shown that malnutrition can reduce animal semen volume and fructose content, while severe nutritional deficiencies can lead to impaired sperm production. In today's world of relatively abundant food, besides diseases, the main causes of malnutrition are food choices and partial eating. Malnourished people often lack amino acids, vitamins and trace elements to varying degrees. The production, maturity and mobility of sperm are closely related to amino acids, vitamin a, vitamin b, vitamin c, vitamin e and trace elements such as zinc, calcium, iron and selenium. If these substances are lacking in the diet, sperm production can be reduced and sperm motility can be reduced, leading to infertility. Overnutrition can also lead to male infertility. This potential danger often begins in childhood. Excess nutrition in childhood can lead to obesity. Fat deposition makes the posterior lobe of the pituitary gland fatty, leading to the loss or decline of pituitary function. The release of male hormones is reduced, resulting in testicular atrophy, penile agenesis, etc. The possibility of infertility in adulthood is great.
2、 Long term partial eclipse
Long term preference for certain foods, such as cottonseed oil and celery, can lead to the decrease of sperm quantity and quality and induce infertility. Among them, infertility and sterility caused by eating cottonseed oil have been confirmed by both clinical and experimental studies, so it should be avoided as far as possible. In addition, shark fin has always been regarded as a delicious and nourishing dish by the Chinese people, and many white-collar workers have a particular fondness for it. However, a study by the University of Hong Kong suggests that high levels of mercury in shark fins can lead to male infertility. The reason why seafood contains mercury is related to marine pollution, and sharks are at the top of the marine food chain, often accumulating a large amount of pollution toxins in their bodies. In addition, sharks have a longer growth period than ordinary fish, so they have a longer time to absorb and accumulate toxic substances than other fish. Therefore, friends who are fond of eating shark fins should also stop eating them in moderation.
3、 Long term consumption of contaminated food
Long term consumption of food contaminated with chemicals is an important factor in reducing male fertility. Experts from the UK Government Medical Science Committee have found that the decrease in male sperm count and testicular shrinkage in the past decade is related to octylphenol, butylphthalate, and other substances, which are widely used in food packaging bags and detergents. These chemicals have estrogenic effects and can inhibit testicular development and sperm formation. In addition, frequent consumption of food contaminated with chemical herbicides, insecticides, fungicides, or heavy metals such as copper, manganese, aluminum, cadmium, and lead can also affect sperm production and development, leading to infertility.
From this, it can be seen that in order to have a healthy baby, men must regulate their mouths. Firstly, it is necessary to eat less or avoid foods that are not conducive to reproductive health. Secondly, it is also necessary to correct the habit of partial eating, achieve a balanced diet, ensure sufficient intake of vitamins and trace elements, and make sure to correct the two extremes of insufficient nutrition and excess nutrition.
