Oxidative Stress in Sperm Abnormalities: Impact of Reactive Oxygen Species (ROS) on Sperm Harm

In the realm of reproductive health, a lesser-known condition called Pyospermia has been gaining attention for its potential impact on male fertility. This article delves into the intricacies of Pyospermia, its causes, and the role it plays in male infertility.

Pyospermia is a condition characterised by an abnormally high number of white blood cells in semen. More specifically, it is defined as having over 1 million round cells per millilitre of semen [1]. These white blood cells, essential for the body's immune response, are the main source of oxidative stress in semen, producing 1,000 times more reactive oxygen species (ROS) than sperm cells [2].

ROS are a natural byproduct of various cellular processes, but in excess, they can cause oxidative stress. This condition arises when the balance between free radicals and antioxidants is disrupted, leading to cellular damage [3]. ROS exists in various forms, including Superoxide radicals, hydrogen peroxide, hydroxyl radicals, and singlet oxygen [4].

In the context of male infertility, oxidative stress can have detrimental effects on sperm cells. High levels of ROS can damage proteins, fats, and genetic material in cells, leading to impaired sperm function and viability [5]. Studies have shown that individuals with Pyospermia have higher levels of white blood cells in their semen, correlating with lower sperm count, reduced movement, and abnormal sperm structure [6].

The origin of oxidative stress in male infertility can stem from the failure of Sertoli cells to adequately clear cellular debris, leading to increased ROS levels in the semen environment [1]. In Pyospermia, the excess leukocytes generate ROS at high levels, overwhelming the seminal antioxidant defenses. This oxidative environment negatively impacts sperm motility, morphology, and can induce DNA fragmentation, all key factors in reduced male fertility.

It is important to note that cells require low levels of ROS for important processes such as immunity, cell communication, and energy production [7]. However, when ROS levels rise, as they do in Pyospermia, they can cause cellular damage and contribute to the development and progression of several diseases, including cancer, diabetes, metabolic disorders, and heart disease [8].

To prevent oxidative stress in general, one can adopt a healthier lifestyle. This includes consuming more antioxidant-rich foods such as Vitamin C, Vitamin E, Selenium, Beta Carotene, quitting smoking, reducing stress, regularly exercising, regularly wearing suncream, drinking less alcohol, and being cautious with medications and chemicals [9].

For those who identify as AMAB and wish to reduce their risk of developing Pyospermia, practicing safe sex, avoiding injury to the pelvic region, avoiding tobacco and marijuana products, reducing alcohol use, and maintaining general good health are recommended [10].

In conclusion, Pyospermia, with its associated oxidative stress, plays a significant role in male infertility by damaging sperm cells. Awareness and understanding of this condition can lead to early detection and appropriate treatment, potentially improving male fertility outcomes.
