But a new study published this month in the Journal of Sexual Medicine has found that testosterone is in crisis, at least when it comes to American Millennials and Gen Z-ers. Men’s testosterone is supposed to decline naturally with age, but this study, which was presented last October to the Sexual Medicine Society of North America, showed a shocking decline in the levels of cohorts of young American men throughout since 1999. The authors tested the serum testosterone (total amount of testosterone present in the blood) of 4,045 men aged between 15 and 39—making sure to control for confounding factors such as age, race, and level of physical activity—and still the results were unmistakable. In fact, they have been slashed by over one-quarter in the last two decades. This is hardly surprising news. Data showing how sperm counts have fallen has been widely reported in recent years. Since the testes produce both testosterone and sperm cells, it is probable that the causes overlap partially or entirely. Laptops too close to the crotch, anyone?
Could the dratted men’s rights activists be right after all? Men’s rights activists, easily dismissed with that devilishly vague slur ‘conspiracy theorist’, warn of endocrine disruptors in the food supply, and xenoestrogens in the water. Identifying the cause, for now, is a bit like playing bingo for diagnosing modern-day malaise. The ubiquity of internet pornography? The decimation of manual labor among the working classes? Soy-based baby foods? Since studying the effects of any one of these things would never be funded for study by the educational-industrial complex, it is impossible to know how they might tie in. The poor diets and sedentary lifestyles that many young Americans enjoy are certain to be among the major contributing factors, but that cannot explain all of the downturn. This is because the study authors also controlled for overweightness, a known enemy of testosterone, by looking at the decline in only those young men who had healthy BMIs. Even these men saw their testosterone scores drop by over one-fifth.
This means, for example, that a 60-year-old man in 2004 had testosterone levels 17% lower than those of a 60-year-old in 1987.
Studies show that men's testosterone levels have been declining for decades. The most prominent, a 2007 study in the Journal of Clinical Endocrinology and Metabolism, revealed a “substantial” drop in U.S. men's testosterone levels since the 1980s, with average levels declining by about 1% per year.Oct 2, 2017
New study shows Testosterone Levels in American Males are Dropping Dramatically. Why?
Many frozen or prepackaged meals and snacks are processed foods. They offer little nutritional value and tend to be high in calories, salt, fat, and sugar.
In particular, processed foods often contain high amounts of trans fats, which can reduce testosterone levels and impair testicular function, according to the results of a 2017 study.
Chemicals in plastic packaging can affect testosterone levels.
Foods and drinks that are canned or packaged in plastic can impact hormone levels.
For example, this can occur when people ingest chemicals, such as bisphenol A (BPA) or bisphenol S, from water in plastic bottles or reheated food in plastic containers.
Results of a study from 2013 suggest that men who work in environments with high levels of BPA have reduced levels of free testosterone and androstenedione, a hormone that can convert into testosterone or estrogen.
It is important to note that participants in this study worked in factory settings. In food packaging, BPA is present in much smaller quantities.
Nonetheless, the chemical does enter many people's bodies. A study from 2011, for example, found BPA in the urine of 89 percent of men attending a fertility clinic.
Those with BPA in their urine also had lower levels of testosterone and thyroid stimulating hormone. When levels of this hormone are low, it can indicate hypothyroidism, a condition that can reduce testosterone in some men.

Obesity is a likely culprit, as is too much masturbation.
A poor diet can really impact on male virility. And too much "self indulgence" can, too.
Obama loved the Castro regime...He turned things around with Cuba and if Hillary had won, Cuba may have become the 51st State...Thankfully Trump put them back on the right track...
