First, what is low testosterone? Testosterone is the primary male sex hormone and a key anabolic steroid. It helps promote secondary sexual characteristics such as increased muscle and bone mass and the growth of body hair. It is also important in mood and energy levels. Men with low testosterone often have low libido, erectile dysfunction, osteoporosis, sleeping problems, depressed mood, and decreased physical performance. Some men only have one or two of these symptoms.

High Intensity Interval Training - This training uses resistance and weight lifting. In one recent study, the increase was 8% higher T levels after HIT versus 5% increases with low intensity. HIT has been shown to improve T levels in all age groups, another recent paper showed TT levels increased in 17% in sedentary 60-70 yo men after HIIT, they previously showed no benefit with simple cardiovascular exercise.

Lose the Pounds - Fat cells in the body convert testosterone to estrogen, which not only removes the male sex hormone but increases the female predominant hormone. Higher levels of body fat are strongly correlated to lower levels of testosterone. In a recent meta-analysis, diet associated weight loss of 9.8% body weight increased total testosterone levels by 84 ng/dL and surgical weight loss (bariatric surgery) increased total testosterone levels by 251 ng/dL on average. That is a huge gain. And that happens at smaller levels, even weight loss of 5% has been shown to increase T levels.

Get Better Sleep: We are all told to get better sleep but it is hard to do in our modern society. Sleep fragmentation and lack of sleep lead to predictably lower testosterone levels. In older men, morning testosterone levels are partly predicted by total sleep time.

Healthier Eating - Expanding on weight loss, Obese and overweight men who lose weight through low-fat, low-calorie diets seem to have improvements in their erectile function and testosterone levels.  In addition, the Western Diet is associated with lower semen quality parameters. Switching to a more mediteranean, low-fat diet may be beneficial to all three parameters. https://www.ncbi.nlm.nih.gov/pubmed/1...

Beware of Herbal Supplements - many companies will try and sell you pills or powders that will boost your testosterone. Many herbal companies will do the same. Oral supplements such as androstenedione, DHEA, and other pro hormones sell increased T levels. Most have no effect on T at all and only increase estrogen levels. Androstenedione has a short and modest impact on testosterone and after a short period of time return to normal but does increase estrogen. Many herbal supplements tout increased levels of testosterone. Some have been shown effective in animals, but no benefit in humans. Tribulus terrestrial, Tinospora cordifolia, and icariin are all commonly used ones that have not been shown to be beneficial.

Stop the opioids - Narcotic medications suppress leutinizing hormone production which decreases your bodies ability to naturally produce testosterone. Narcotic use is rampant, and testosterone deficiency is high amongst those using pain relievers. Up to 86% of men using chronic pain medications had low testosterone. Regardless if it is pills, patches, or injections, narcotic use will decrease your testosterone. Think of it as another great reason to stop taking narcotic medications.
