2ĭo higher testosterone levels correlate with increased muscle growth? The anecdotal evidence says so as steroids are commonly used to increase muscle growth. This suggests that DIM may actually have estrogen and testosterone blocking affects at lower doses. DIM at 10mg/kg also lowered the number of androgen receptors expressed in testicular and prostate tissue. That dose did not affect sperm growth or testicular tissue. It also lowered estrogen levels from 8.00 pg/mL in controls to 4.56 pg/mL. In the study DIM at 10 mg/kg (a dose of 700 mg for the average 70 kg man) slightly lowered testosterone levels from 4.77 ng/mL in control subjects to 3.81 ng/mL. Researchers monitored spermatological parameters as well as serum testosterone and estradiol levels. The control group received corn oil, while the other three received varying amounts of DIM for a study period of 53 days. In one study, 38 male rats were split into four different groups.

Does DIM boost testosterone production? Let’s find out.

One of the reasons why many men choose to take DIM supplements is to boost testosterone production for athletic and bodybuilding purposes. Let’s take a look at the research to see if DIM can actually do these things.ĭIM may affect hormones in both men and women.

DIM, or diindolylmethane, is a compound that forms in the body from the breakdown of plant substances, most commonly cruciferous vegetables, including broccoli, cabbage, cauliflower, and Brussels sprouts.
