The relationship between psychological stress and male infertility, and a rational understanding of zinc supplementation and tonics.

Can psychological stress lead to infertility?

Traditional thinking holds that infertility is mostly caused by psychological factors, which were once estimated to account for about 40% to 50% of infertility cases.

Currently, with a clearer understanding of the causes of male infertility, stress-related male infertility is found to account for only 5% to 10%. Psychological factors leading to low male fertility are mainly due to stress, which disrupts the body's neuroendocrine system and causes abnormal secretion of sex hormones. Since sex hormones promote sperm production, stress interferes with sperm generation, leading to male infertility.

In the biological world, it has been confirmed that psychological changes within an animal group can have a stimulating effect, thereby influencing the sexual activity and reproductive function of male animals.

In humans, psychological stress caused by external stimuli can affect the secretion of testosterone in men and inhibit sperm production; this phenomenon has been scientifically proven.

The earliest research in this area was conducted in prisons with long-term inmates sentenced to death but not yet executed. The research data showed that the inmates' sperm count was suppressed, confirming that the environment can alter psychological factors, and that psychological state can restrict male fertility.

Another study on male athletes found that male athletes undergoing intensive training showed a significant decrease in sexual activity during the first month of intense training; tests on their androgen levels showed that both androgen secretion and metabolism were reduced.

The above research results indicate that sudden or persistent adverse stimuli in the external environment can cause psychological imbalance in some individuals (especially those with low psychological resilience and who are not good at facing adversity and setbacks with optimism), thereby affecting reproductive capacity and, in severe cases, causing infertility. Therefore, the negative impact of psychological factors cannot be ignored in the clinical examination of male infertility.

Another noteworthy phenomenon is that in clinical practice, doctors often only recognize that male sexual dysfunction can affect the harmony of marriage and family, but they neglect the impact of various adverse factors in marriage and family on male sexual function and sperm quality.

Psychological trauma before and after marriage, lack of knowledge about reproductive physiology, lack of sexual experience, fear of pregnancy, fear of sexual life, and disharmony in sexual life can all cause negative psychological states such as depression, guilt, and repression in patients, which can affect the sexual function of male patients, leading to anejaculation and infertility.

Because a fulfilling sex life requires close coordination between partners, any abnormality in one partner not only creates mental stress for the other but also affects and even negatively impacts their partner. Conversely, changes in the partner's emotions and attitudes can also increase psychological pressure on the partner. This mutually destructive cycle creates a vicious circle, making negative psychological states increasingly complex and pessimistic, and ultimately leading to sexual dysfunction.

In short, couples should pay attention to cultivating a good marital and family atmosphere to avoid causing mental stress and infertility.

What foods rich in zinc should infertile patients eat?

In addition to taking appropriate zinc supplements and using traditional Chinese medicine (such as psoralea, wolfberry, epimedium, he shou wu, dodder seed, privet fruit, and cistanche, all of which are high in zinc), infertile patients with zinc deficiency can also supplement their diet with foods rich in zinc, such as apples, liver, eggs, fish, meat, peanuts, walnuts, and oats.

Can infertility be cured by taking some tonics?

In clinical practice, we often encounter couples who have been infertile for many years. They then blindly take tonics such as ginseng, deer antler, seahorse, and dog kidney in hopes of conceiving soon. However, this method of self-purchasing tonics without medical guidance not only wastes money but also often negatively impacts the treatment outcome for infertility.

Traditional Chinese medicine (TCM) emphasizes a holistic approach and "treatment based on syndrome differentiation." This means selecting different medications based on the specific condition; the medication used must be suitable for your condition, and a good medicine is one that suits your symptoms. Chinese herbs are categorized by their "four properties and five flavors," and the application range varies depending on the properties and flavors of each herb. For example, deer antler and seahorse are more tonifying in nature and flavor, suitable for treating patients with Yang deficiency, but unsuitable for Yin deficiency, and may even worsen the condition. Therefore, we urge infertile couples not to indiscriminately use medications but to use them under the guidance of a professional doctor to avoid adverse effects. Any claims that a certain Chinese herbal medicine can cure all infertility are lies by charlatans and should never be believed.
