Regular exercise is beneficial for your health, and certain workouts can temporarily raise testosterone. A small study of healthy young men showed that their T levels dropped by 10 to 15 percent when they only slept for five hours a night. T levels increase while you sleep, peaking around 3 a.m. Limiting high-sugar and high-fat foods will help keep testosterone in a healthy range, too.

Notably, it decreases testosterone production and facilitates fat gain (and we’ll see that fat gain itself can impair testosterone production). Chinese researchers found the equivalent of 500mg – roughly the amount in 5-10g of grape skins – was enough to raise T-levels and improve epididymal motility (your sperm’s ability to swim).

For example, a 50-year-old man with testosterone levels of 8.5 nmol/l but no symptoms would unlikely benefit from treatment, even though his levels are outside the normal range. Finally, it’s thought that this negative feedback loop becomes overly sensitive with time, preventing testosterone release, even when testosterone levels are not particularly raised . Normally, when testosterone levels get too high, the body detects this and prevents more being made. It can impair testicular function and interfere with hormone production. While extreme endurance-based exercises have been shown to possibly reduce testosterone, that doesn’t mean you should cut out the cardio.

During puberty, natural testosterone helps with growth spurts by promoting bone growth. Alcohol consumption can reduce the production and release of hormones that are needed for reproductive functions and interfere with hormone production in the hypothalamus. The top magnesium-rich foods that boost testosterone include wheat bran, dark chocolate, sunflower seeds, pumpkin seeds, cooked spinach, banana, amaranth and almond butter.

Heavy resistance exercise has been shown, in some studies at least, to increase post-exercise testosterone levels temporarily. However, this temporary surge doesn’t do much for muscle growth, and designing a training program to maximize post-exercise hormone levels is unlikely to have much of an impact on the speed at which muscle is gained. But when they looked at the data, the researchers could find no significant link between the exercise-induced rise in testosterone levels and gains in muscle mass. Post-exercise changes in testosterone levels also fail to explain why some people build muscle faster than others, even when they eat and train the same. Blood samples taken 5, 15, 30, 60, 90, and 120 minutes after training show a significant increase in testosterone levels.

The hypothalamus instructs the pituitary gland to release luteinising hormone (LH) which prompts the Leydig cells in the testes to produce testosterone. In the high volume workouts involving higher reps and short (60 seconds) rest periods between sets, there was also a spike in both human growth hormone (HGH) and IGF-1 levels, two hormones that often are labelled “anabolic.” Here’s a closer look at what the research has to say on the subject of the barbell squat, testosterone and muscle growth.
