Ginger enhances semen quality and improves sperm parameters, an impact linked to increased levels of gonadal hormones, decreased cell damage, and valued nutrients in ginger.
In the methodological approach, this study conducted a systematic review of original research articles listed on Scopus and PubMed. The search terms applied were "ginger," "sperm," and "semen," to find studies published in English from August 2004 to February 2019 that explored the biological effects of ginger or ginger extracts on semen quality and sperm parameters.
In the discussion of the results, the main conclusion was that there is clear evidence that ginger betters semen quality and advances primary sperm attributes such as concentration, viability, motility, and morphology. This enhancement is presumably due to increased levels of gonadal hormones, particularly testosterone and luteinising hormone, reduced oxidative damage to cells, increased production of nitric oxide, hypoglycaemic response of ginger, and the presence of valuable nutrients in ginger such as manganese.
