Testosterone production is an outcome of processes that happen at three different glands. GnRH is a hormone released by the hypothalamus, which triggers the production of the LH and FSH in the anterior pituitary gland. LH and FSH, in turn lead to the production of testosterone in the testes.

Heavy drinking has an impact on all three of these glands.

Research suggests that more than 15 drinks of alcohol consumption a week regularly leads to poorer testicular function. It specifically impacts the Leydig cells in the testicles that are instrumental in testosterone production.

Chronic alcohol misuse has also been related to improper release of GnRH, FH and LSH.

So, one more reason to not engage in heavy drinking, as if it was needed!
