BTW, this eerily resembles questions involving the myth that humans only use 10% of our mental capacity. Evolution is never so needlessly profligate (the human brain consist of only 2 percent of total body weight, yet demands 20 percent of our resting metabolic energy.)
Causes of osteoporosis. Osteoporosis causes bones to become less dense and more fragile. Some people are more at risk than others. Bones are at their thickest and strongest in your early adult life and their density increases until your late 20s. But you gradually start losing bone density from around the age of 35.en continue producing testosterone into old age, but the risk of osteoporosis is increased in men with low levels of testosterone. In around half of men, the exact cause of low testosterone levels is unknown, but known causes include: 1  the use of certain medications, such as oral glucocorticoids. 2  alcohol misuse.
Genes are not solely to blame for the cause of osteoporosis; there are other factors as well which can lead to osteoporosis. Osteoporosis is the loss of bone mass. For example, being deficient or not consuming enough calcium can contribute to loss of bone mass, which then contributes to osteoporosis.ew genetic cause of osteoporosis found, rare gene identified. By: Bel Marra Health | Osteoporosis | Tuesday, September 15, 2015 - 17:30 PM. A rare gene â the EN1 gene â has been identified as a potential osteoporosis cause by researchers at McGill University.
