Closer Look Below the Belt
The testes produce testosterone within Leydig cells, which are relatively inactive until puberty; then they begin to erratically produce testosterone in a manner that suggests a developing regulatory system. The regulation of testosterone production involves two glands located in the brain called the hypothalamus and the pituitary. The hypothalamus detects the concentration of testosterone and its metabolites, estradiol and DHT.1,2 When the concentration is low, the hypothalamus sends a signal (GnRH) to the pituitary, which responds by sending a hormonal signal (LH) to the testes to produce more testosterone. If testosterone approaches the upper limit of the “normal” range, the hypothalamus backs off its signal, as does the pituitary gland, and the testes slow down testosterone production until the level drops. This results in the pulsatile (ups and downs) pattern of circulating (blood) testosterone concentrations.
Protecting the nuts actually begins before conception, as epigenetic effects can alter the sperm, egg (ovum) and fetal physiology. Since a person cannot choose his parents, it is best to focus on factors that can be influenced. Few studies have looked at the childhood environment to determine later effect on testosterone production. One investigated the effect of swimming on later testes function, following children who swam in pools treated with chlorine (either indoors or outdoors) or a silver-based system. The intent was to see if exposure to biogenic chloramines (created when the chlorine in the water interacts with sweat or urine) or halogenated hydrocarbons (formed when chlorine interacts with “organic matter”) affected the testes. Indeed, boys who swam in indoor chlorine-treated pools (>250 hours by age 10; or >125 hours by age 7) had lower testosterone concentrations later in life; below the tenth percentile, which means less than 90 percent of their peers.3 It was proposed that the chlorinated byproducts were absorbed across the scrotal skin and injured the Leydig cells during a critical point in development. Outdoor chlorine-treated pools did not have the same effect – presumably because the urine and waste contamination was less, as they were largely privately owned pools in this study.
Possible Endocrine Disruptors
Other chemical assaults occur during all phases of life as well, possibly responsible in part for the declining age-matched testosterone concentration that has been noted over several generations. This means that at your age, your father likely had higher (natural) testosterone than you, and his father more so than your father. This population-based decline in testosterone has occurred in addition to the aging-related decline in testosterone that thankfully appears to be declining at the same rate across generations, just from a lower starting point in younger men in comparison to their elders. Though most prominently reported in the United States, this phenomenon has been described in other countries as well.4,5
The causative agents are likely legion (meaning a huge number).6 It has been grossly underreported that many chemicals interfere with the sex steroid hormone balance. These chemicals, collectively referred to as endocrine disruptors, are particularly problematic for children and infants. However, due to the bias against testosterone-related research, little is known about the extent of damage caused by the combined effect of all the endocrine disruptors in our food, beverage and even the air we breathe.

WHO IS THE KING OF ALL FREAKS- RONNIE OR RAMY?
When Big Ramy was crowned Mr. Olympia last December, it was the first time a man over 250 pounds had held that title in over a decade. At 290 pounds, we hadn’t seen such a mass monster rule the sport since the days of Ronnie and Jay. Ronnie Coleman remains the heaviest man to ever win the Mr. Olympia at a bodyweight of 296 in 2004. Comparisons between the two colossal men, Ramy and Ronnie, soon sprung up everywhere online and in social media. Who is the king of all freaks? To answer that, we sought out the best-qualified men to answer that question: Giles Thomas, Ronnie Coleman himself, and the only man to coach both champions to Mr. Olympia wins, Chad Nicholls.

IN SEASON Chickpeas (GARBANZO BEANS)
Chickpeas appear in early recordings in Turkey well over 5000 years ago. India produces the most chickpeas worldwide but they are grown in more than 50 countries. An excellent source of carbohydrates, protein, fiber, B vitamins, and some minerals, they are a nutritious staple of many diets. The name chickpea comes from the Latin word cancer, referring to the plant family of legumes, Fabaceae. It is also known by its popular Spanish-derived name, the garbanzo bean. Kidney beans, black beans, lima beans, and peanuts are other familiar foods found in this legume family.
