From stress to toxins, uncover the surprising factors impacting male fertility
When a couple is struggling to conceive, the focus often turns first to the female partner. However, male factor infertility accounts for up to 50% of all infertility cases [1]. While issues like low sperm count or erectile dysfunction may be well known, there are several lesser-known, yet truly impactful, causes of male infertility that can significantly affect a man’s fertility.
Let’s dive into five contributing factors to male infertility issues and what you can do to address them.
1. Elevated Testicular Temperature
One of the most clearly documented underlying causes of male infertility is elevated testicular temperature, which has a negative effect on sperm production. For optimal semen quality, the testicles need to be 2-4°C cooler than the core body temperature [2]. Unfortunately, many modern lifestyle choices can cause the temperature of the testicles to rise. For instance, frequent use of laptops placed directly on the lap, wearing tight-fitting clothing, and prolonged sitting can all contribute to elevated testicular temperatures [3].
The effects of heat exposure on sperm production can be seen within just hours. One study found that sitting in a sauna for just 15 minutes twice a week for three months resulted in a marked decline in sperm count and motility. And these declines lasted for up to three months, even after ending sauna use! [4]
The good news is that this health issue is generally reversible once the heat exposure is removed. Making simple changes like using a laptop desk or working at a table, wearing looser clothing, and taking frequent standing breaks can help keep testicular temperatures in the optimal range. There are also some really fascinating products out there now, such as Snowballs, a kind of specialized boxer briefs with a built-in cooling pouch!
2. Stress
Stress is another often overlooked but significant contributing factor to infertile men. When the body is under stress, it releases cortisol from the adrenal glands. Cortisol can suppress testosterone production and disrupt the hypothalamic-pituitary-gonadal axis, which controls reproductive hormone production [5].
Chronic stress has been shown to decrease semen quality, negatively impacting sperm concentration, motility, and morphology [6]. Stress can also lead to erectile dysfunction, premature ejaculation, decreased libido, or other sexual dysfunction, making conception more difficult.
Managing stress through techniques like mindfulness, exercise, time in nature, and adaptogenic herbs such as ashwagandha can be powerful tools for supporting male fertility. Ashwagandha has been shown in studies to reduce cortisol levels, improve semen parameters, and increase testosterone in men under stress [7].
3. Environmental Factors
Exposure to environmental toxins is a growing concern for reproductive health. Many common toxins like phthalates, BPA, and pesticides interfere with hormone levels, impacting the quality of sperm [8].
These toxins are ubiquitous in our environment, found in everything from plastic food containers to personal care products. They can accumulate in body tissues over time, disrupting the function of reproductive organs like the prostate gland and seminal vesicles. And many are lipophilic, meaning they concentrate in fatty tissues like the brain and testicles… which means they live there for a very long time and are incredibly difficult to extract.
Exposure to endocrine-disrupting chemicals has been linked to decreased semen quality, erectile dysfunction, and even increased risk of testicular cancer [9]. While it’s impossible to avoid all toxin exposure, simple steps like choosing organic foods, using natural cleaning and personal care products, and filtering air and water can help reduce your toxic burden, which, in turn, can improve sperm problems.
4. Gut Microbiome Imbalances
The gut microbiome is an often overlooked but critical piece of the fertility puzzle. Emerging research shows a strong connection between gut health and reproductive function. The billions of bacteria living in our gut play important roles in hormone metabolism, nutrient absorption, and inflammation regulation.
Imbalances in the gut microbiome, known as dysbiosis, have been linked to a range of health issues, including infertility. One study found that men with poor semen quality had significantly different gut bacteria compositions compared to men with healthy sperm [10].
Supporting gut health through probiotic-rich foods, targeted supplementation, and identifying and removing food sensitivities can be powerful tools for optimizing male fertility. In our practice, we use comprehensive gut testing to identify root causes in the microbiome that then guide our treatment protocols.
5. Nutrient Deficiencies
Proper nutrition forms the foundation for healthy reproductive function. Several key nutrients are particularly important for male fertility, including zinc, selenium, vitamin D, vitamin E, vitamin C, folate, and omega-3 fatty acids [11].
- Zinc is critical for testosterone production and sperm formation
- Selenium is a potent antioxidant that protects sperm from oxidative damage.
- Vitamin D helps maintain semen quality and sperm count
- Vitamin E is another powerful antioxidant that shields sperm cells from damage and helps maintain their structural integrity
- Low folate levels have been linked to poor semen quality and increased risk of sperm DNA damage.
- Omega-3 fatty acids are essential for healthy sperm cell membranes and have been associated with better sperm motility and morphology
Unfortunately, nutrient deficiencies are common, even in developed countries. Stress, poor diet, and gut health issues can all contribute to decreased nutrient absorption.
Targeted supplementation with these key nutrients, along with a nutrient-dense whole foods diet, can significantly improve sperm health and overall fertility.
It’s important to note that these factors don’t exist in isolation. They often interact and compound each other. For example, stress can alter the gut microbiome, leading to decreased nutrient absorption. Environmental toxins can deplete the body of antioxidants like vitamin C and selenium. This is why, in functional fertility, we always take a holistic, whole-systems approach to health and fertility.
Conclusion
Male infertility is a complex issue that can be influenced by a variety of surprising factors beyond just sperm count. Elevated testicular temperature, chronic stress, environmental toxins, gut microbiome imbalances, and nutrient deficiencies can all play significant roles in male reproductive health.
The good news is that by identifying and addressing these root causes through a functional medicine approach, it’s possible to greatly improve male fertility naturally. Simple lifestyle changes like keeping the testicles cool, managing stress, reducing toxin exposure, supporting gut health, and optimizing nutrition can have a profound impact on sperm health and overall reproductive function.
