Oxidative stress is an imbalance in the cellular environment, produced by toxic factors that surround us and that are especially aggressive to sperm. It can affect sperm in several ways: their development throughout their evolution, their morphology, their ability to move (motility), and their fertile capacity since it damages their DNA. This explains the sperm damage.
Antioxidants are substances, essentially natural products, that we find in our food and try to rebalance the balance of sperm metabolism between free radicals (oxidative stress) and antioxidants in the body (the body's ability to combat them), increasing the latter and repairing the damage caused.
Multiple studies have shown that antioxidants (L-Carnitine, Coenzyme Q10, Vitamin E, Vitamin C, Selenium, Zinc) produce an increase in both the number of spermatozoa and their mobility.
In spite of all this, the effectiveness of antioxidants is only given by correct diagnosis and an adequate therapeutic guideline when faced with a certain process of infertility.
