However, ginger could decrease apoptosis in the group IV that received 100 mg kg−1 rat−1 of ginger. The results revealed that there was a significant increase in apoptosis in the group III when compared with the other groups. Gentamicin and ofloxacin affect the spermatozoa by affecting their number, motility and morphology. Likewise, in another research, sperm parameters significantly decreased in the streptozocin‐induced diabetic rat group. The results showed that cyclophosphamide led to a decrease in body weight, and spermatogenesis. Thus far, all studies that have found a direct link between ginger or its derived compounds and testosterone were in vivo system studies, and no human studies were conducted in this specific research context. Various studies have measured testicular weight as a marker for reproductive capability following dietary supplements. It is well-known that the vasodilation effect of NO increased blood flow in the blood vessels 58,59. In fact, several studies have introduced the antihyperglycemic effect of dietary ginger on blood glucose 49,50,51. However, when ginger-derived compounds like zingerone, geraniol, and 6-gingerol were administered separately, they did not significantly affect testosterone levels in diabetic rats. Numerous in vivo studies have explored the potential link between ginger and testosterone levels. Ginger supplementation has been found to increase NO production, which can enhance testosterone levels. Studies have shown that men with diabetes and suboptimal blood sugar levels are at increased risk of developing testosterone deficiency in the future. Ginger has also been found to regulate blood glucose levels, which is important for maintaining healthy testosterone levels. By reducing oxidative stress and enhancing the antioxidant defense mechanism, ginger may promote testosterone production. This increase in testosterone levels is significant and suggests that ginger may be a natural and effective way to maintain healthy testosterone levels. The most often cited study, conducted on 75 men between the ages of 19 and 40, found that consistent ginger supplementation for three months led to a 17.7% increase in testosterone levels. Several studies have investigated the effects of ginger supplementation on testosterone production and have consistently found promising results. While the findings from animal studies provide valuable insights, it is important to note that the effects of ginger on human testosterone levels are not yet confirmed and require further clinical research. In conclusion, the mainstream of research that links ginger to testosterone demonstrated that ginger supplementation, particularly in oxidative stress conditions, enhances testosterone production in males. The comprehensive improvements across sperm parameters, hormone levels, and oxidative stress markers indicate multiple beneficial pathways. The study’s findings suggest that ginger could serve as a standalone treatment option for certain cases of male infertility, potentially reducing the need for more expensive or invasive interventions. The researchers explain that ginger’s phenolic compounds function as antioxidants by capturing free radicals and reactive oxygen species before they can damage sperm cells. Understanding why ginger produces these effects requires examining what goes wrong in male infertility. This activity is reflected by the increase of both testis weight and serum testosterone levels," the researchers noted in their findings. Insufficient levels of testosterone in men are linked with a wide range of disorders/diseases such as infertility , diabetes , osteoporosis , and bone loss . Such an intention is due to the crucial function of testosterone as the major sex hormone in males . All these studies are very promising in terms of the ginger-testosterone relationship. Most studies on the matter have been on rats, with only one human study accessible online. Basically, testosterone is an androgenic steroid hormone that supports the development of male traits in the body. Officinale is reflected by the normalization of antioxidant activities and concurrent decrease of MDA," the research team documented. This protective effect normalizes antioxidant activities while simultaneously reducing oxidative damage markers. With infertility rates varying significantly between countries and regions, accessible and affordable interventions become particularly valuable. Even ejaculate volume showed substantial improvement, rising by 36.1% after ginger treatment. Participants showed remarkable improvements across multiple fertility markers. Additionally, luteinizing hormone (LH) surged by an impressive 43.2%, while follicle-stimulating hormone (FSH) rose by 17.6%. The research, conducted by Prof. Mossa M. Morbat and colleagues at Tikrit University’s medical facilities, followed fifteen infertile men over nearly a year, administering 2 grams of ginger daily through capsule form.
