yes
Wearing tight underwear can increase scrotal temperature, which may lower testosterone levels in men.
Men can live without testosterone. The men that have low testosterone can be at high risk of dying.
There is no scientific evidence to suggest that wearing boxers increases testosterone levels in men. Testosterone levels are primarily influenced by genetics, age, overall health, and lifestyle factors. The type of underwear a man wears is unlikely to have a significant impact on testosterone levels.
Yes, arousal can increase testosterone levels in the body.
No, donating blood does not increase testosterone levels in the body.
No, applying icing to testicles does not increase testosterone levels.
Smoking appears to increase testosterone levels : "Smoking men had 15% higher total and 13% higher free testosterone levels compared with men who never smoked. Thus, smoking seems to be an important confounding factor when evaluating testosterone levels, and could possibly mask borderline hypogonadism." http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2605.2006.00720.x/abstract
No, according to all studies I have seen levothyroxine actually will increase Your total testosterone. I am not sure HOW it does so. But levothyroxine also increases SHBG (sexual hormone binding globuline) significantly thus decreasing the speed at which testosterone is excreted. I find it reasonable that the decreased speed in excretion will be at least partially responsible for the increase in total testosterone. There may however be also other reasons for the increase in total testosterone like increased testosterone production due to increased metabolism ? Note, if You use levothyroxine to compensate for hypothyroidism You will likely become hyperthyroid if You also add testosterone .....
There is no scientific evidence to suggest that icing your testicles can increase testosterone levels.
The hormone that women have that is equivalent to testosterone in men is called estrogen.
masturbate 3to 4 times a day n the hormone production rate will increase..............moreover try ways to increase men sexuality
Yes it has a compound that slows the transformation of testosterone into estrogen.
