Hi Ali: Regarding the mint studies…I just saw this on Suppversity…regarding the difference between mints effects on male and female rats…..Spearmint (M. spicata): At least in women spearmint tea has been shown to increase estrogen and luteinizing hormone in the follicular phase of their menstrual cycle (Aktodgan. 2007). In a 2004 study that was conducted on male rodents, on the other hand, the daily administration of peppermint tea (M. spicata) for a period of 30days lead to significant increases in luteinizing and follicle stimulating hormone and increases in serum testosterone, yet with the serious downside of “extensive degenerative changes in the germinal epithelium and spermatogenesis arrest compared with the findings in the testicular biopsies of the control group” (Aktogan. 2003) interesting for sure!
An eight-ounce oyster has 18 grams of protein — making gains easy while upping your t-levels. Oysters are rich in zinc, a t-boosting mineral. From food, you get about 10 milligrams of zinc each day, but the body only absorbs 2-3 milligrams of it — putting you at risk for a deficiency. The common cold is actually a symptom of low zinc levels along with a low sex-drive, which is an indication of low-t levels. When low zinc levels are present, the pituitary gland limits the release of the luteinizing and follicle stimulating hormones; they are responsible for triggering T production in the testes. This then decrease the amount of androgen binding sites and free testosterone in the blood stream.
To investigate whether endurance running in men produced basal hormonal changes similar to those reported in women, we obtained blood samples from 31 men running at least 64 km each week and 18 sedentary controls for measurement of levels of total testosterone, non-sex hormone-binding globulin-bound and free testosterone, luteinizing hormone, follicle-stimulating hormone, prolactin, and cortisol. The mean levels of total and nonspecifically bound testosterone as well as prolactin were significantly lower than in controls, although levels remained within the physiological range. Other hormone levels were similar in both groups. The lowered testosterone and prolactin levels parallel the changes reported in women runners.
