About
What you eat can affect levels of testosterone as well as other hormones. Resistance training, such as weightlifting, has been shown to boost testosterone levels in the short term. Interestingly, testosterone also plays an important role in female health and sexual well-being. Additionally, increasing your testosterone to optimal levels may increase muscle mass and strength. In adult males, healthy levels are important for general health, including disease risk and sexual function.
Ginger roots were found to enhance the activity of certain antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) in different male reproductive organs such as testis, prostate, and epididymis . These antioxidants protect both the reproductive organs from oxidative stress, an imbalance between prooxidants (reactive oxygen species such as superoxide ion, hydroxyl radical, and hydrogen peroxide) and antioxidants to the favor of the former , and lipid peroxidation. The synthesis of testosterone occurs in the Leydig cells, while the Sertoli cells utilize the produced testosterone for spermatogenesis.
Ginger root is rich with several potent antioxidant compounds such as gingerols, zingerone, zingiberene, glucosides-6-gingerdiol, flavonoids, and volatile oils . As a general trend, the studied toxicans reduced the level of testosterone in the experimental animals, and ginger supplementation counteracted this reduction. Also, to date, almost all of the reproductive toxicity studies are rodent studies. As shown in the table, diabetic and hypertensive rat models supplemented with ginger and its extracts had a higher serum testosterone level compared to controls. To achieve this contribution, we searched the PubMed, Web of Science, and Scopus databases for English language articles (published in full texts or only abstracts) from November 1991 through August 2018 using the keywords "ginger" and "Zingiber officinale" versus "testosterone". In addition, ginger contains several antioxidant compounds such as vitamin C, vitamin E, beta-carotene, lutein, lycopene, quercetin, genistein, and tannin . The beneficial effect of ginger in such diseases is mainly due to its antioxidant 13,14, antimicrobial , and anti-inflammatory properties .
Therefore, the simultaneous use of ginger (100 mg kg−1 day−1) and cinnamon (75 mg kg−1day−1) increases the level of androgens (LH and FSH) and serum testosterone and also improve the specialized parameters of sperm fertility in patients with diabetes (Khaki et al., 2014). The researchers also confirmed the effects of ginger on increasing the serum concentrations of testosterone, LH and FSH, and observed a significant increase in total sperm count, motility and sperm viability. In this study, following the use of the ginger extract, the concentration of cholesterol and glucose in semen plasma also increased (Saeid et al., 2011). In this study, all sperm fertility parameters, serum hormone concentrations and semen plasma hormones were measured every 4 weeks (from week 24 to 44 weeks). Although the use of high concentrations of ginger (30 g), significantly increased sperm penetration in the perivitelline membrane and improved fertility, there was no statistically significant difference in the rate of duration of incubation and mortality of chicks due to the use of ginger powder.
In this type of abnormality, the main parts of the sperm (head, middle and tail) are affected and lead to the formation of sperm with small, large, broadheads, or double and abnormal tails. Primary abnormalities occur in the process of spermatogenesis and in seminiferous ducts of testis. On the other hand, sperm abnormalities in Lingen, Bangkok, Kedu and Arabian roosters were reported to be 10.40%, 13.78%, 17.03% and 9.07%, respectively (Almahdi et al., 2014). The mean pH of semen in roosters of Kedu‐Lingen, Bangkok, and the Arab breeds is 6.92, 6.98 and 7.04, respectively. The cause of the low volume of semen in poultry, compared with mammals, is the lack of sexual glands. In general, the volume of semen in roosters, ducks and quail is 300–1,000 μl, 0.1–1 ml and 50–150 ml, respectively. Fertility levels drop sharply after 40–45 weeks and reach their lowest levels in 65–70 weeks.
Several in vivo trials have utilized different dietary supplements and medicinal plants to enhance testosterone production in males. Ginger may also enhance semen quality by improving the concentration, motility, and viability of sperm cells (20, 21). While more research is needed, some studies suggest that oxidative stress could even negatively impact fertility and sexual function (13, 14).
