Men who eat soy products such as tofu should be careful. According to recent reports from multiple media outlets in the United States, a study from the Harvard School of Public Health has once again confirmed that consuming soy products every day can significantly reduce male sperm count.
This study was conducted by George W? Dr. Chavaro completed. From 2000 to 2006, researchers tracked and surveyed 99 males. The research results are surprising: Men who consume soy products every day have only 41 million sperm per milliliter of semen, significantly lower than men who consume less soy products. It is understood that if the number of sperm per milliliter of semen is less than 20 million, it belongs to low sperm concentration and is prone to infertility. In addition, this connection is more evident in obese men.
Chavaro believes that soy products have adverse effects on the male reproductive system, especially sperm production. Soybeans and their products contain abundant isoflavone phytoestrogens. If consumed excessively, it will naturally affect the levels of male hormones in the body, leading to a series of adverse consequences.
There have also been male experts in China who have suggested that consuming too much soy products can affect the number of male sperm. In the past 5 years, Pan Lianjun, a male doctor at Nanjing Maternal and Child Health Hospital, has been paying attention to this issue. He also found that men who frequently consume soy products are 3.46 times more likely to experience erectile dysfunction than those who do not.
Daily nourishing and nourishing foods for men
1. Arginine is the main component of sperm head production and needs to improve sperm motility. The tokens rich in arginine include sea cucumber, eel, loach, cuttlefish, sesame, yam, ginkgo, tofu skin, frozen tofu, peanut kernels, sunflower seeds, hazelnuts, etc. Since ancient times, sea cucumbers have been regarded as treasures for tonifying the kidneys, tonifying the essence, strengthening the yang, and treating impotence.
2. Eating foods containing magnesium. Magnesium helps regulate human heart activity, lower blood pressure, prevent heart disease, and improve male fertility. It is suggested that men should have 2 bowls of oatmeal Congee with milk and 1 banana for breakfast. Foods containing magnesium include soybeans, potatoes, walnuts, oatmeal Congee, macaroni, leafy vegetables and seafood.
3. Sperm is rich in trace element zinc, which plays a crucial role in maintaining male reproductive function. Because zinc is an essential substance for sperm metabolism and can enhance sperm vitality, it is necessary to eat more zinc rich tokens such as oysters, shrimp, clams, shellfish, animal liver, walnut kernels, milk, beans, bran, and lotus seeds. Oyster meat has the highest zinc content among the public, emphasizing the intake of nucleic acid and protein that helps sperm metabolism, and can improve sexual performance. However, the daily amount of zinc should never exceed 15 micrograms, as excessive consumption of zinc can affect the effects of other minerals in the human body. 120 grams of lean meat contains 7.5 micrograms of zinc.
4. Calcium plays an important role in sperm motility, capacitation, maintenance of hyaluronidase activity and fertilization. If the body lacks calcium, it will slow down sperm motility and reduce the activity of sperm acrosin. So men should also pay attention to consuming more calcium rich tokens, such as milk, soy products, dried fish, rib soup, seaweed, shrimp skin, kelp, Undaria pinnatifida, goldenrod, shiitake mushrooms, mustard, coriander, sweet almonds, raisins, etc.
