Did you know that in the United States, as in Europe, male fertility is collapsing*? In the space of 5 decades, sperm density has fallen by 60%! How can we support male fertility in a natural and simple way? Discover one potential way, backed up by the latest scientific publications.
Male fertility plays a vital role in helping couples start or grow their families, with healthy, active sperm being the cornerstone of conception. Sperm production and function rely on several factors, one of which is selenium, a trace mineral crucial for male reproductive health. Selenium supports sperm production, enhances motility, and shields sperm cells from oxidative damage, while also helping to maintain proper testosterone levels, essential for male fertility. Although selenium is present in foods like Brazilian nuts, seafood, and eggs, it can be difficult to maintain adequate levels through diet alone. Selenium-enriched yeast offers a natural supplement to help boost fertility, improve sperm quality, and increase the chances of conception.
Factors Affecting Male Fertility
Male fertility depends on several factors, including sperm production and sperm health. This process of sperm production – also known as spermatogenesis – takes place in the testes and occurs throughout a man’s life.
For optimal fertility, a healthy sperm count—measured by the number of sperm in a given volume of semen—is critical. When sperm count is low (called oligospermia), the changes of conception are reduced. Healthy, high-quality sperm are also active and motile; they can ‘swim’ towards an egg, with movement powered by a long rotating tail. Testosterone is also a critical factor in male fertility, as it regulates libido and sperm production.
Male fertility is affected by environmental, lifestyle, and dietary factors. Proper nutrition is essential for supporting male fertility and key nutrients – like selenium – can improve sperm health and ultimately increase the chances of successful conception.
Importance of Selenium in Male Fertility
Selenium is an essential nutrient for male fertility due to its pivotal role in sperm production, protection, and motility.1,2 This trace mineral acts by binding to various proteins within the cells of the testes, forming selenoproteins, which are critical for the process of spermatogenesis.
Spermatogenesis and Sperm Motility
During spermatogenesis, selenoproteins support sperm cell development.3 One such selenoprotein, phospholipid hydroperoxide glutathione peroxidase (PHGPx), plays a structural role in sperm cells, while also acting as an antioxidant. This protein, alongside others like Glutathione peroxidase 4 (GPX4), protects sperm cells, safeguarding them from oxidative damage. GPX4 also contributes to sperm tail structures and hence supports sperm motility.
Antioxidant Protection
Oxidative stress is one of the most common causes of sperm dysfunction. The body naturally produces reactive oxygen species (ROS), which in excessive amounts can lead to damage, including sperm. Selenium plays a protective role against this damage.2 Selenoproteins like GPX4 can neutralize ROS and inhibit oxidative damage. This is critical, to pass on a healthy genetic code.
Hormonal Balance
Selenium may also help regulate testosterone production. In fact, research suggests that selenium supplementation can help maintain or even increase testosterone levels in men. In part, this is because selenoproteins protect the cells in the testes and support increased.

In part, this is because selenoproteins protect the cells in the testes, enabling them to produce more of this fertility-related hormone.
A balanced testosterone level is key to maintaining a healthy libido, supporting sexual function, as well as ensuring proper spermatogenesis.4 Thus, selenium both directly and indirectly supports male reproductive health through its protective effects on testosterone production and regulation.
Selenium-Enriched Yeast as Male Fertility Support
Maintaining optimal selenium levels is essential for male fertility, and selenium-enriched yeast offers an effective solution to achieve this.1 Selenium-enriched yeast refers to a strain of nutritional yeast that has been engineered to contain higher levels of this critical nutrient. This yeast is grown in a selenium-rich environment, allowing it to absorb and convert the mineral into an organic form that is highly bioavailable for the human body.
Compared to inorganic selenium sources, selenium-enriched yeast is more easily absorbed and utilized, making it an excellent choice for supplementation. This bioavailable form of selenium supports all the key reproductive functions—spermatogenesis, sperm motility, and testosterone regulation—while protecting sperm cells from oxidative stress. When choosing a supplement, it’s important to select a brand that emphasizes quality and product safety, as proper dosing is crucial for realizing selenium’s fertility benefits.
Incorporating selenium-enriched yeast into your diet may offer a natural, accessible way to improve male fertility and overall reproductive health.
Selenium Can Also Benefit Female Fertility
Often, female fertility is a critical consideration when preparing for conception. Male fertility alone is only one side of the equation, as both partners typically play roles in achieving a successful pregnancy.
Selenium is crucial for male fertility and plays a vital role in female reproductive health.5 For women, selenium helps support proper ovarian function, egg quality, and the maintenance of a healthy reproductive system.6 Its antioxidant properties are thought to protect eggs from oxidative damage, much like they do for sperm cells in men.7 This protection is essential, as healthy eggs increase the chances of successful fertilization, implantation, and pregnancy.
Moreover, selenium works synergistically with folate, another key nutrient for female fertility. Folate, often recommended for women trying to conceive, supports cell division and the development of a healthy embryo.8 When combined with selenium, this duo creates a powerful support system for reproductive health.9 Together, they form a potent combination that can enhance fertility for both men and women.
Conclusion
Selenium-fortified nutritional yeast provides a natural and bioavailable solution for supporting male fertility. By improving sperm count, motility, and protecting against oxidative stress, selenium offers significant reproductive benefits. For men and women looking to boost fertility, selenium-enriched yeast is a valuable supplement to consider in their wellness routine.
