Selenium is a component of a series of enzymes that affect sperm production and metabolism, and selenium deficiency can lead to insufficient sperm production. Studies have confirmed that selenium is a metabolic element against certain sperm toxicity, which can prevent harmful substances from injuring the reproductive system and maintain the normal shape of sperm cells.
Selenium deficiency can affect sperm motility; cause metabolic disorders in the body, excessive generation of lipid peroxide metabolite malondialdehyde, damage cell biofilm, decrease cellular and humoral immune functions, and affect the normal development of embryos.
In 1998, doctors at Glasgow Royal Infirmary in Scotland published a study evaluating selenium supplementation in Scottish men . The results showed that selenium supplementation improved sperm quality in men with previously low selenium levels. The study also highlights that the recommended daily allowance (RDA) of selenium is necessary for normal sperm production.
Selenium exerts a powerful antioxidant effect through GSH2Px, which can resist various damages caused by active oxygen and free radicals oxidizing cell membranes, such as causing biochemical abnormalities such as DNA, RNA, and enzymes, interfering with the synthesis and metabolism of nucleic acids, proteins, mucopolysaccharides, and enzymes. Directly affect cell division, growth and development, reproduction, inheritance, etc., thereby protecting the stability and permeability of the cell membrane, so that the life activities of the body can be carried out normally.
