MSG – Is it safe for men


I stumbled on this research MSG and was shocked about the hamful effects of food seasoning on male fertility. If these researches are true, then a lot of boys that eat food containing this food seasoning would have fertility challenges in future.


Monosodium Glutamate (MSG), a sodium salt of glutamic acid is one of the main flavor enhancer used in various food products associated with food in Chinese restaurants. The flavor enhancer comes in common names such as Vedan, Sasa, Ajinomoto, Miwan and Weichaun, among others (Geha et al., 2000).

MSG gives a feeling of special taste (Leung and Foster, 1996). It stimulates taste, enhances and improves appetite (Eweka, 2007).

In large amount it may cause chest pain sensation, facial pressure, headaches, burning sensation, excessive fluid retention and sweating (Xiong et al., 2009), resulting in a condition called “Chinese restaurant syndrome”.

Most Nigerians use MSG to remove stains from fabrics (Kondoh and Torii, 2008). Reports indicated that Mis toxic to human and experizmental animals (Eweka, 2007). Harmful or toxic effects of MSG have been reported in experimental animals and man (Hayes, 1982; Eweka, 2007).

According to Igwebuike et al. (2011), the oral administration of MSG results in lower serum testosterone levels and reduction in the caudal epididymis sperm reserves of male rats. MSG causes testicular hemorrhage, degeneration and alteration of sperm population and morphology (Oforofuo et al., 1997;Das and Ghosh, 2010), hence could lead to infertility. MSG can severely destroy testicular tissues and affect spermatogenesis also causing a decrease in their testicular weight and testicular diameter, reduction in germinal epithelium height, decrease in sperm count and increase in abnormalities of sperm morphology (Das and Ghosh, 2010; Nosseir et al., 2012).

The best advice for men is to avoid food seasoning if they still want to become fathers.
