A published study confirms what has been suspected for some time, which is that men in the Boston area over the past two decades are showing declining levels of testosterone (male hormone), in their blood. Over twenty years the average testosterone level in these men dropped from 501 to 391. Many experts regard a testosterone lower than 300 to be abnormally low and possibly needing testosterone replacement treatment. One of the scientists on the study, Dr. Thomas Travison states that when comparing testosterone levels in Boston men from 1987 to 2005 a decline in the testosterone level in every adult age group was found over this time. The researcher stated that the speed with which the levels of male hormone declined over the twenty years and the uniformity of the decline in all age groups was cause for concern.
It is known that testosterone levels decline slowly as men age. Declining male hormone levels were found even in the 45 to 71 year age range, however. Other known causes of declining testosterone levels, the growing incidence of obesity and sedentary life style in Boston men, did not explain the findings, say the researchers.
Could other factors be at work here? Alcohol has a powerful effect on male hormone levels for many reasons. Some alcohol products like bourbon and beer may have estrogen (female hormone) like plant products in them. Liver disease from excess alcohol consumption can also reduce the level of male hormone. Other drugs may have a negative effect on male hormone production such as cannabis (marijuana, Mary Jane, pot, herb, weed, splif, ganja, the bomb, the shit etc.). Although not nearly as wide spread in its use are the opiate type drugs, heroine, methadone, opium, codeine, hydrocodone etc. which can severely depress male hormone levels.
Environmental pollutants are known to cause adverse hormonal effects in men. Pollutants such as PCB’s and DDT act like female hormone and could reduce a man’s testicular function (the testicle is the site of testosterone and sperm production in men). Even herbal products can have anti-male hormone effect such as soy, black cohosh, and white clover. Perhaps the Boston men are being exposed to these influences more now then in the past and the result is sinking male hormone levels.
Before concluding that Boston men are simply pot smoking, beer drinking, soy eating effeminate couch potatoes, the authors of the study call for additional research into the possible origins of this serious loss of virility hormone in the Boston area.
