Introduction

Pyospermia, also known as leukocytospermia, is a condition where there is an abnormally high number of white blood cells (leukocytes) in semen. White blood cells are a normal part of the immune system and help protect against infections by releasing substances called reactive oxygen species (ROS).^1,2 In small amounts, ROS are useful, but when too many white blood cells are present, they release excessive ROS. This leads to oxidative stress, which occurs when the body’s natural antioxidants can't keep up, resulting in damage to sperm and other reproductive tissues. Such damage can impair sperm function and is believed to be linked to around 30% of male infertility cases, according to some studies.^2,3 This article will explore how diet and nutrition may help reduce oxidative stress and improve outcomes for men with pyospermia.

Role of antioxidants in managing pyospermia

Given that excess reactive oxygen species (ROS) in pyospermia are primarily due to elevated white blood cell levels in semen, it is reasonable to conclude that antioxidants play a key role in neutralising oxidative stress. By reducing the damaging effects of ROS, antioxidants may help in managing pyospermia.

How antioxidants counteract oxidative stress

Antioxidants can reverse the effects caused by the ROS in pyospermia, but how? Below are ways in which antioxidants can counter the effects of oxidative stress:

1. Neutralising reactive oxygen species: Antioxidant agents like vitamin C, vitamin E, zinc, and other antioxidants obtained from vegetables, fruits, and other food products seek out the ROS and clean out the free radicals by donating electrons to stabilise the reactive oxygen species. In doing this, it reverses the negative effect ROS has on semen quality^4,5
2. Enhancing internal defence: In pyospermia, the endogenous antioxidants present in the semen are not enough to fight off the effects of excess ROS. Eating foods and supplements rich in antioxidants helps increase the capacities of the antioxidant systems in the body, whether preventive or scavenging. An example of the enzymes linked to the antioxidant systems are Superoxide Dismutase (SOD) and Glutathione Peroxidase (GPX)⁴
3. Repairing damaged sperm: infertility as a result of damaged sperm from a study was seen to be improved when antioxidant supplements were administered. To mention a few of the results observed, Coenzyme Q10 enhanced the catalase enzyme in the semen, boosted antioxidant levels, and improved sperm motility and concentration. Lycopene increases the movement of the sperm cells, sperm count and concentration. Omega-3 reduces the splitting of DNA. While generally, L-carnitine improves the sperm structures and movements⁵

Dietary sources vs supplements

Antioxidants help manage pyospermia by restoring the body’s oxidative balance and supporting the repair of sperm damage. Whole foods like berries, nuts, and tomatoes naturally provide antioxidants in a safe and bioavailable form. In cases of high oxidative stress, targeted supplements, such as Coenzyme Q10 (CoQ10), can offer additional support. Clinical guidelines often recommend a combination of antioxidant-rich dietary changes and evidence-based supplementation, ideally under the guidance of a healthcare professional.^5,6

Dietary sources

Having a diet that contains antioxidant-rich food provides additional nutrients with fewer risks of overdose. Examples of antioxidants that can be gotten from diets include: 

• Vitamin C, which helps to improve the movement and structure of sperm cells, can be found in Citrus fruits, strawberries, and broccoli⁷
• Vitamin E protects the sperm membranes from the harmful effects of reactive oxygen species. Nuts, seeds, spinach⁵
• Lycopene reduces the attack of free radicals on lipids. Although some studies suggest that taking lycopene excessively may be linked to a lower sperm count. Lycopene is found in tomatoes and watermelons, although it has its limits; according to some studies, taking it in excess can be linked to reduced sperm count⁷
• Zinc and Selenium, which are found in oysters, legumes, and Brazil nuts, are essential for the production of sperm cells and antioxidant enzyme function⁵

It’s also important to note that adopting a Mediterranean-style diet, rich in fruits, vegetables, whole grains, and omega-3 fatty acids, has been linked to improved semen quality. One study found that men with normal sperm profiles consumed about 60% more antioxidants than those with poor semen quality, highlighting the role of diet in reproductive health.⁷

Supplements 

Supplements in the case of pyospermia are formulations that work to address deficiencies or severe oxidative stress. For example, the CoQ10, selenium, zinc and folate. The antioxidants can be combined into supplements to address the condition. Examples of combined supplements are: 

1. Menevit®, which is a combination of vitamins C/E, zinc, and folate, reduced ROS by 28% and increased clinical pregnancy rates by 15% in high-ROS males⁸
2. CoQ10 (200 mg/day) + selenium (200 µg/day) improved sperm motility by 22% and concentration by 18% when the cause of oligoasthenoteratozoospermia (OAT) is not known. OAT is described as a low amount of sperm cells, sperm with poor motility, and an increased frequency of abnormal sperm⁵

Benefits of Vitamin C in pyospermia 

Vitamin C plays a vital role in managing pyospermia by reducing oxidative stress and supporting overall sperm health. One of its key functions is protecting sperm DNA from damage caused by reactive oxygen species (ROS). It does this by donating electrons to neutralise ROS, preventing them from breaking apart sperm DNA or damaging the lipid membranes that protect sperm cells. This antioxidant action helps improve sperm count, motility, and morphology.^9,10

Vitamin C also supports the immune system by enhancing the ability of immune cells to engulf and remove pathogens, helping reduce inflammation linked to infection, one of the contributing factors in pyospermia.¹¹

Men can increase their vitamin C intake through a diet rich in fruits and vegetables such as tomatoes, grapefruit, oranges, kiwi, broccoli, red peppers, and strawberries. The recommended dietary allowance (RDA) for adult men is 90 mg per day, but therapeutic doses for improving sperm quality often range between 1,000–2,000 mg daily, under medical supervision.⁹

Benefits of vitamin E in pyospermia

Like vitamin C, vitamin E helps reduce oxidative stress by neutralising reactive oxygen species (ROS) that damage the lipids forming the sperm membrane. By doing so, it helps preserve the integrity of the sperm membrane and reduces the effects of pyospermia.¹² 

Vitamin E also plays a direct role in protecting sperm DNA from fragmentation and helps prevent the formation of abnormal chromosomes. In addition to safeguarding genetic material, it improves both the number and motility of sperm cells.¹² 

Foods rich in vitamin E that can support men with pyospermia include almonds, sunflower seeds and oils, hazelnuts, wheat germ oil, spinach, and red bell pepper.

The recommended dietary allowance (RDA) for adult men is 15 mg per day, but for fertility support, doses of 200–400 mg daily are commonly used, typically under medical guidance.^12,13

FAQs

Can dietary sources for antioxidants replace the supplements in treating pyospermia?

It depends on the scenario. If it is a mild case, dietary sources can suffice. However, for severe cases, the amount of vitamin C and E needed per day may not be achievable from diet alone. For instance, vitamin C and E are needed for 1000 mg/day and 400mg/day to improve sperm health, which can be met by supplement intake.

What foods are best for boosting vitamin C and E antioxidants?

Foods like oranges, grapefruit, bell peppers, and strawberries supply vitamin C. Vitamin E can be gotten from almonds, sunflower seeds, spinach, and olive oil.

Is it safe to take antioxidants in high doses?

Taking antioxidants in high doses should be done under the supervision of a medical expert, as it may cause some side effects.

Summary

In summary, a diet rich in antioxidants, particularly vitamins C and E, can play a significant role in reducing the impact of pyospermia and improving fertility outcomes. This article outlined how these vitamins help combat oxidative stress, protect sperm DNA, and enhance sperm quality, motility, and count.

While dietary changes can be a valuable part of managing pyospermia, they are most effective when combined with appropriate medical treatment. However, it's important to note that long-term or high-dose use of antioxidant supplements should always be done under medical supervision to avoid potential side effects or imbalances.
