It is understood that many factors can affect male reproductive health, with environmental pollution being one of the key factors. Additionally, prolonged internet use, long periods of sitting on soft sofas, drug abuse, mobile phone radiation, and excessive psychological stress can all lead to a decline in sperm quality, resulting in low sperm count or weak sperm. Diet is also an important influencing factor. Here's a reminder for men: during the preparation for pregnancy, it’s best to minimize consumption of the following foods:
1. Barbecued and Fried Foods - Can Lead to Low/Weak Sperm
Research reports indicate that barbecued and fried foods can cause low or weak sperm counts in men. Moreover, heavy metals like cadmium and pesticide residues are toxic to sperm.
2. Caffeinated Beverages - Can Reduce Libido
The caffeine in coffee stimulates the sympathetic nervous system, which controls all daytime activities. When stimulated, people feel more energetic and lively. The parasympathetic nervous system, on the other hand, manages nighttime physiological functions, including erections and sexual activities. It has an inverse relationship with the sympathetic nervous system. When the sympathetic nervous system is frequently active, the relatively weaker parasympathetic nervous system is suppressed, clinically manifested as reduced libido. Therefore, individuals who experience significant emotional fluctuations and whose sympathetic nervous systems are easily excited should avoid drinking caffeinated beverages before sex to prevent suppressing the parasympathetic nervous system and reducing libido.
In Western beverages, there has been a prevalent belief that "Coke kills sperm." Dr. Zhan stated that this claim requires further scientific research.
3. Beer - Can Harm Kidneys and Reduce Sperm Count
Beer directly affects male fertility. Medical research has found that certain substances in hops can mimic the function of estrogen, affecting sperm movement and thus reducing male fertility efficiency. If some male friends already have kidney problems and drink large amounts of beer without restriction, uric acid deposition can lead to renal tubule obstruction, causing kidney failure. The condition of the kidneys is also related to male "vitality."
4. Celery - Has Spermicidal Effects
Doctors have discovered through experiments that eating too much celery can inhibit the production of testosterone, leading to spermicidal effects and reducing sperm count. Healthy young males with good fertility who continuously consume celery will see a significant reduction in sperm count, potentially even to levels where conception becomes difficult. This situation will return to normal several months after stopping the consumption of celery.
5. Soy Products - Can Decrease Male Vitality
It is commonly said that eating soy products is beneficial to health, especially tofu. The protein in tofu has an absorption rate of up to 90% in the human body. However, a survey found that men who eat soy products every day have only 41 million sperm per milliliter of semen, significantly lower than those who eat fewer soy products. A sperm count of less than 20 million per milliliter of semen indicates low sperm concentration, making it harder to conceive. Soy contains rich amounts of isoflavones, which are plant estrogens. If consumed excessively, they can affect the level of male hormones in the body, leading to various adverse consequences. Therefore, it is recommended not to eat soy products more than three times a week, with each serving being about 100 grams. This ensures nutrition while avoiding "side effects."
6. Bubble Tea - Can Inhibit Sperm Activity
Currently, most bubble teas on the market are made from creamer, food coloring, flavoring, tapioca pearls (referring to the pearls in the tea), and tap water. The main component of creamer is hydrogenated vegetable oil, which is a type of trans fat. Trans fats reduce the secretion of male hormones and negatively impact sperm activity, interrupting the reaction process of sperm in the body.
7. Eating Pig Kidneys to Supplement Kidneys? Smoking + Eating Pig Kidneys Leads to a 60% Infertility Rate
There is an old Chinese saying: "Nourish shape with shape," but this does not apply to "kidneys." Research has found that the livers and kidneys of pigs, cows, and sheep contain varying levels of heavy metal cadmium. While people eat these organs to supplement their diet, they also ingest cadmium, which may lead to infertility. If combined with smoking, the infertility rate can reach as high as 60%.
