This research showed a high expression of Cyp19 aromatase receptors in the brain cells of the control group, vice versa of the treatment group (Figure-2). This was confirmed in the level of testosterone between treatments compared to control after 50 days of shell administration, which was significantly different (p Salehi et al. found that testosterone level of certain snakes living in four seasons is greatly affected by spermatogenesis and body weight. This scientific evidence confirms that oyster extracts do increase testosterone, but not many people understand why. Notably, Zn functions to increase testosterone in humans by blocking the aromatase enzyme. This is not a setup because there is scientific evidence that very well answers why are oysters good for testosterone. Testosterone which starts to decline after a certain age can be revived with the help of some testosterone-boosting foods and one of them is oysters. Moving on, while the nutritional content of oysters is commendable, can it also be responsible for increasing the testosterone hormones? Let’s look at the evidence and what research has to say about the link between oysters and testosterone boosts. The two things you need more than anything to increase your testosterone are foods that are rich in zinc and vitamin D (D3). This quick and easy treatment (you can watch a pellet-insertion video here) is less conventional than the other three methods mentioned, but far more convenient and equally effective at delivering a steady supply of supplemental testosterone to the body. For this reason alone, users looking to simply boost T may do better by supplementing a T-booster stack that includes Zinc & D-Aspartic Acid—the two most effective male-enhancing constituents found in oyster meat (and perhaps two of the best T-boosters in general). The dipeptides VR and IR have been reported to exhibit inhibitory activity against ACE (Ko et al., 2017; Liu et al., 2021). ACE inhibitors prevent the hydrolysis of angiotensin I by ACE, achieved through the formation of hydrogen and hydrophobic bonds that interact with multiple amino acid residues at the ACE active site. The hydrophilic amino acids at the C‐terminus make it easier for the peptide to provide hydrogen atoms for bursting free radicals (Li et al., 2011). The activity of antioxidant enzymes regulated by NRF2 was decreased significantly, and JNK signaling was inhibited, indicating that cellular oxidative stress was alleviated. TM3 cells are a type of mouse testicular Leydig cells that serve as an in vitro model for investigating the effects of chemicals on testosterone biosynthesis (Bara & Kaul, 2018). Figure 10 presents the results of the molecular docking analysis of the three dipeptides (RI, IR, and VR) with the ACE protein. Notably, raw oysters have the maximum level of vitamins and minerals. Much to your surprise, 3 ounces of raw oysters are packed with 33 grams of zinc. Another study demonstrates that 4-week zinc supplementation can prevent thyroid hormones and testosterone concentrations in wrestlers after exhaustion exercise. Oysters are an excellent source of zinc which is essential for male sexual and fertility health. These nutrients trigger the natural production of testosterone and raise its level.
