A systematic review on the effect of Ginger (Zingiber officinale) on improvement of biological and fertility indices of sperm in laboratory animals, poultry and humans

There is an evidence that ginger enhance semen quality via improving different sperm parameters mainly count, viability, motility, morphology and DNA integrity. According to research results in various species, ginger seems to have strong antioxidant properties (due to the presence of active phenolic compounds) and androgenic activity. Ginger improves semen quality and increases fertility of sperm by disrupting the production of free radicals, dissolving oxidative chain reactions, reducing oxidative stress and altering the levels of gonadotropin hormones (LH, FSH) and sex hormones (such as testosterone). The antioxidant and androgenic properties of ginger give a sperm with normal morphological structure (head, middle and tail) and more integrated chromatin. The rate of DNA failure and damage to the mitochondrial genome in these cells is minimal and they have the most progressive motility, the highest viability and the best fertility. Therefore, the use of the ginger significantly improves the biological parameters of sperm (number, total motility, survival rate and normal morphology) and also increases all specialized fertility indicators of sperm. Tacking account of lacking literature and possibility of toxicity and adverse effect of ginger on vital organ, further clinical trial especially on evaluating the safety and clinical effect must be considered. Also, dose and duration of consumption by monitoring of health indicators and biochemical changes in all species such as human, animal and poultry must be applied.

Automated summary

Ginger has been shown to enhance semen quality and increase fertility of sperm through its antioxidant and androgenic properties. It improves sperm parameters such as count, viability, motility, morphology, DNA integrity, and hormone levels. Further clinical trials are needed to assess the safety and clinical effects of ginger on different species, and monitoring of health indicators and biochemical changes is necessary for dose and duration determination.
