Antioxidants Role in Infertility

Antioxidants Role in Infertility


What is N-acetylcysteine (NAC)?

N-Acetyl Cysteine is a derivative of cysteine amino acid with antioxidant and cytoprotective role (cell protection) to the body. NAC is successfully used for the treatment of many diseases for it’s role in glutathione reserve restoration, the most important antioxidant in the body. Regular use of NAC maintains optimal glutathione levels in the body, thus preventing oxidative stress speeding (accelerated growth of free radical number in the body compared to antioxidants).

What is Glutathione (GSH)?

Glutathione is the most abundant natural antioxidant in the body and is found in all its cells. Among the many benefits of glutathione are found: reducing oxidative stress, stimulate the immune system, hepatoprotective, dermatoprotective, antitumor, anti-inflammatory. Oxidative stress occures due to a number of environmental factors, obesity, malnutrition (including low nutritional quality of the diet), smoking, alcohol, etc., so GSH supplementation is beneficial.

Why is NAC important for infertility?

Women with fertility problems undergo a state that can be associated with oxidative stress. Moreover, oxidative stress is close related to growth and aging of the cells therefore close related to the entire process of fertility, from first menstruation until after menopause.

When free radicals are predominant in the cells of the body, oocytes and follicular fluid inclusive are affected. A series of negative changes are produced that lead to decreased oocyte quality, also to a follicular fluid deficient composition. Glutation production is stimulated by NAC administration, thus protecting cells against free radicals and noticeably improving their quality.

Antioxidants are also important in the first days after conception, protecting the unborn child cells, preventing miscarriage.

Why  MYO-SUN®PLUS NAC is necessary?

According to medical studies, GSH level in infertile women is low. N-acetylcysteine administration increases follicular level glutathione, therefore oocytes are protected from the harmful effects of free radicals. NAC has an important role in quality and thus proper maturation of oocytes, but also in restoring follicular’s fluid normal composition.
