Semen oxidative stress

The oxidative stress of semen affects fertility.

Statistics show that about 50% of infertility problems are caused by male factors. In about half of these cases, the semen analysis is normal and the cause remains unexplained. Recent studies have found that oxidative stress in semen is a major factor affecting male fertility.

Oxidative stress refers to an imbalance in the oxidation-reduction state of cells. Stress occurs when the amount of reactive oxygen species (ROS) exceeds the body’s own antioxidant defence capacity. Minor oxidative stress is required for normal sperm function, but excessive stress impairs fertility and may cause damage to the sperm’s surface, motility and genetic material, the DNA.

Several internal and external factors can affect the level of oxidative stress. External factors include air pollution, smoking, alcohol consumption, aging and stress. Internal factors such as varicose veins in the testicles, infections and certain general diseases, such as diabetes, can cause oxidative stress. The level of oxidative stress can be influenced in many cases and the situation can be corrected.

The level of oxidative stress of semen can be measured

Felicitas Mehiläinen uses a new method to study oxidative stress in semen. The study provides additional information on the quality and fertility of semen in addition to traditional semen analysis. A small amount of semen is required for the study and it can be performed on the same sample used for semen analysis.

If excessive oxidative stress is found in the semen, any factors affecting health and lifestyles are discussed with the doctor to reduce the level of oxidative stress. In addition, the use of an antioxidant aimed at reducing the amount of oxidative stress can be started.
