The Importance of Exercise and Diet for Male Reproductive Health and Nutritional Needs at Different Age Groups

Physical exercise plays an irreplaceable role in physical health. Appropriate exercise can help men enhance their physical functions, significantly improving the cardiovascular, respiratory, digestive, nervous, endocrine, and immune systems, including the reproductive system. Long-term lack of exercise can affect sperm quality and may lead to decreased sexual function, thus reducing fertility and, in severe cases, infertility. Furthermore, men who lack exercise are prone to obesity, which can negatively impact testicular sperm growth, development, and regulation, resulting in low sperm count, asthenospermia, and even decreased sexual function and degeneration of sexual characteristics. Therefore, it is recommended to engage in aerobic exercise 2-3 times per week, such as brisk walking, jogging, or swimming. The intensity of each session doesn't need to be excessive; consistency is key.

Clinically, the phenomenon of illnesses entering through the mouth is very common. The high incidence of stomach diseases, liver diseases, and various lifestyle-related diseases is closely linked to poor dietary habits. In fact, male infertility can also be caused by diet; cases of infertility due to dietary imbalances, overnutrition, or malnutrition are increasingly common. For men of reproductive age, understanding the connection between diet and infertility is very helpful in preventing and treating infertility.

What is the connection between diet and infertility? Charles Darwin, who proposed the theory of evolution, stated that animals with good nutrition and abundant food supplies have stronger fertility. Similarly, when humans receive sufficient nutrition, their growth, development, sexual function, and reproductive capacity will be better. Conversely, malnutrition or insufficient daily calorie intake will significantly affect sperm count and reproductive capacity. For men, adequate protein, vitamins, and appropriate amounts of trace elements are essential for maintaining normal fertility. This is because protein and vitamins promote sperm production; vitamins A, B vitamins, and vitamin E are indispensable elements for maintaining reproductive function; and appropriate amounts of trace elements, such as zinc, manganese, and selenium, ensure normal testicular spermatogenesis and healthy, motile sperm.

Of course, because sufficient nutrition enhances fertility, many men have the mindset that the more supplements they take, the better. This is actually incorrect; excessive supplementation in men can lead to infertility. First, excessive nutrition during adolescence often leads to obesity. Fat deposition can cause loss or decline in pituitary gland function, resulting in insufficient or reduced release of male hormones. This can easily lead to small testes, micropenis, lack of secondary sexual characteristics, feminization, and other features, potentially causing infertility in adulthood. Second, obesity caused by excessive nutrition in adult men can compress the testes, causing reduced sperm production and decreased sexual function. Over time, this can even lead to testicular atrophy.

However, a proper diet can improve male fertility. In daily life, men can adjust their diet to ensure they get enough protein, vitamin A, vitamin E, B vitamins, and various trace elements, thereby enhancing sexual function, testicular spermatogenesis, and improving sperm quality.

Men work hard every day for their careers and families, expending a lot of energy and needing to replenish it promptly. Otherwise, nutritional deficiencies can easily affect reproductive functions such as sexual function and fertility. Therefore, dietary adjustments are crucial for the prevention and treatment of infertility. In daily life, to maintain fertility or prepare for pregnancy, men's nutritional supplementation should follow these principles.

(1) Appropriate intake of protein-rich foods: Protein is not only an important raw material for the synthesis of semen, but arginine in protein also has the effect of improving sexual function and eliminating fatigue. The main sources of high-quality protein are animal proteins such as poultry, eggs, fish, and meat, as well as legume proteins. Adequate intake of protein foods can not only effectively improve sexual function and maintain a good sex life, but also lay the foundation for healthy reproduction.

(2) Consume adequate amounts of vitamin-rich foods: Vitamin deficiency can easily lead to reduced sperm count, impaired sperm production, decreased libido, and other diseases, thus causing infertility. Green leafy vegetables, fresh fruits, animal liver, and vegetable oils are rich in vitamins A, C, E, and B, making them very suitable for men. Men should include 1-2 fruits and 500g of vegetables in their daily diet.

(3) Consume foods rich in trace elements: Deficiency or excess of trace elements such as zinc, copper, iron, magnesium, manganese, and selenium can reduce semen quality or cause reproductive endocrine disorders, leading to infertility. In daily life, men should eat more oysters, chicken, eggs, chicken liver, and other foods to supplement the trace elements needed by the body and improve male fertility.

(4) Maintain a healthy diet and abstain from smoking and excessive alcohol consumption: Numerous studies have shown that smoking and excessive alcohol consumption impair fertility and are among the causes of infertility. Furthermore, from a eugenic perspective, smoking and excessive alcohol consumption are also undesirable. Men who have not yet fathered children should ideally abstain from smoking and reduce their alcohol consumption.

(5) Eat a variety of foods and avoid long-term unbalanced diets: Some foods can affect sperm production, such as celery, kale, water chestnuts, and cottonseed oil. Long-term consumption may lead to a decrease in sperm count and quality. For example, consuming large amounts of seafood may not only affect sperm motility and count, but also harm physical health.

(6) Ensure adequate nutrition and avoid indiscriminate supplementation: Many men choose to take supplements, especially health products, in order to enhance sexual function and improve fertility. In fact, this is incorrect, because some hormonal drugs or health products not only do not improve fertility, but may also increase sperm abnormality or affect sperm motility, thereby reducing the probability of conception.

(1) Comprehensive nutrition at age 20: At age 20, men are in the golden stage of physical development, with their bones fully formed and becoming stronger. During this period, men are in excellent physical condition, especially active, and their heavy physical labor leads to greater consumption of energy. Nutrition should focus on strengthening the body, ensuring both quality and quantity, with sufficient staple foods, a variety of side dishes, and supplements of various minerals and vitamins.

(2) Prevention and control of sub-health at age 30: By age 30, one's physical condition is basically set, and whether or not one has passed the peak of health varies from person to person. At this time, one should maintain good health through good eating habits and healthy lifestyle habits. According to the Chinese Dietary Standards, it is recommended that men aged 30 strive to diversify their diet, combine whole grains and refined grains, have three reasonable meals a day, eat appropriately when hungry or full, consume moderate amounts of oil, eat a small amount of sweets, and moderate their alcohol consumption.

(3) Dietary Considerations for Men Aged 40-55: Men around 55 years old will enter menopause. In addition to following the above-mentioned dietary guidelines, men aged 40-55 should pay special attention to zinc and vitamin supplementation. Zinc is an active component of enzymes; although present in small amounts, it is crucial for regulating the immune system and promoting growth. Consuming more seafood, lean meat, and whole grains is essential to meet the body's zinc requirements. Appropriate vitamin supplementation helps combat coronary heart disease and prevent hyperlipidemia.

(4) Diet after age 55: Around age 55, men often experience menopausal symptoms such as headaches, general malaise, depression, and palpitations. At this time, consuming foods that improve and enhance gonadal function, such as shrimp, mutton, and walnuts, can fundamentally alleviate these symptoms. Eating more walnut porridge and jujube-mixed rice, which help improve nerve and cardiovascular function, can also help calm the mind and nourish the heart.
