All studies used berry or root extracts of Asian ginseng (Panax ginseng), with the root reported as Korean red ginseng, a processed form (67). Study durations were from 2 h up to 6 mo, with 2 studies having durations of 2 h and 10 h, respectively, and the remaining studies having durations from 4 wk to 6 mo. FT or BT (the combination of FT and albumin-bound, "weakly-bound" testosterone) have been suggested as more effective measures for diagnosing AD, particularly as men age (32). The active ingredient in turmeric is curcumin, known for its anti-inflammatory properties and widely used for various health benefits. A study concluded that 94% of people with knee osteoarthritis symptoms experienced relief from arthritis symptoms with fewer side effects . Research from Harvard Medical School indicates that, aside from its antioxidant benefits, the curcumin in turmeric has anti-inflammatory properties. This makes turmeric supplements a possible solution for those dealing with low testosterone, often linked to diabetes . Turmeric supplementation can help assist in balancing total cholesterol levels in the blood, potentially aiding weight loss and leading to elevated testosterone levels in men . Beyond these beneficial properties, recent studies also revealed that curcumin potentially impacts the reproductive system. Recent studies have confirmed the potential pharmacological actions of curcumin in inflammatory disorders, metabolic syndrome, cardiovascular disease, and neurological disorders1. Curcumin, a diferuloylmethane, is naturally present in turmeric (Curcuma longa). In conclusion, these results indicated that mechanisms of CDC in stimulating testosterone production involve upregulating the cAMP-PKA pathway. However, all of these effects were significantly improved by CDC treatment. CDC could significantly stimulate H89-suppressed StAR and CREB expression but not reverse melatonin-suppressed StAR expression. The previous study revealed that curcumin potentially impacted the reproductive system. Daily supplementation with 800 mg of a tribulus extract for 30 d did not increase testosterone concentrations, while in the Neychev and Mitev study (54) in 21 participants aged 20 to 36 y, a tribulus extract at 2 doses, 10 mg ⸱ kg−1 ⸱ d−1 (3 divided doses) or 20 mg ⸱ kg−1 ⸱ d−1 (3 divided doses), did not increase testosterone concentrations after 4 wk of supplementation. Four studies were conducted examining the effects of ashwagandha on testosterone concentrations (35, 50, 51, 62). In an acute study (2 h) conducted in 8 men with a mean age of 21.3 ± 0.7 y, supplementation of 20 g of Korean red ginseng root extract did not increase testosterone concentrations (65), while in 30 healthy, endurance-trained men, aged between 18 and 40 y, Panax ginseng (an ethanolic liquid extract equivalent to 2 g of dried root, daily) did not increase testosterone concentrations after 6 wk of supplementation (38). Seven studies were conducted examining the effects of Asian ginseng on testosterone concentrations (36–38, 47, 49, 56, 65). The initial search identified 4384 unique studies, of which 32 randomized controlled trials were identified as eligible following assessment using the selection criteria (Figure 1) (35–66). The main findings of this review indicate that 2 herbal extracts, fenugreek seed extracts and ashwagandha root and root/leaf extracts, have positive effects on testosterone concentrations in men. These data indicate that 1-h pretreatment with H89 resulted in a significant diminution in the protein expression of CREB and StAR compared with their expressions in control cells (P 5) and Supplementary Figures. Also, some evidence exists for another herb and herbal extract, Asian red ginseng and forskohlii root extract. From the 4 databases searched, there were 13 herbs identified in 32 studies, published between 2001 and 2019. This means that the CDC might exert two-way regulation in the biological effects of hormones in the body. Our data showed that CDC stimulated testosterone production via cAMP/PKA signaling pathways, upregulating transcription factors (NR5A1 and CREB), and steroidogenic enzymes (StAR, CYP11A1, CYP17A1, and 3β/17β-HSD). Unfortunately, most of us don't have the time, money or devotion to make big lifestyle changes (diet, exercise, stress management, etc.) Besides, there are other factors and hormones involved when it comes to optimizing testosterone — DHT, free and bound testosterone, prolactin, SHBG, cortisol, and so forth. In men, as estrogen increases, testosterone decreases due to negative feedback loops with the hypothalamus, and pituitary gland… which will then affect GnRH, FSH, LH, and so on and so forth. Now, curcumin has lots of benefits and one of the primary ones is to reduce inflammation.
