Shana H. Swan et al.: Sperm 0 Countdown
In 2017, Shana H. In the last 40 years, Dr. Swan has discovered that the number of male sperm in Western countries has dropped by more than half. How could this happen? The amazing discovery was devastating to the world. It was just the beginning. Sexual development has been shown to be widespread in both men and women. For example, young men who had just graduated from college in Boston have found significant declines in sperm concentrations, motorism and total numbers between 2003 and 2013. Those who were on sperm donation passed 69% in 2003 with a sperm quality cut, while 44 percent in 2013. This decline in fertility and sexual ability is occurring in many other parts of the world. This is despite improvements in lifestyle variables, such as men who have improved their drinking, smoking, weight loss and steady exercise. The aftermath is a surge of sterile couples, and are being blamed for the worldwide low births. It is not just a social phenomenon, but a general age challenge with lower reproductive capacity in the human family. It has also been found that the modern world is becoming a ‘ barren planet, ’ with reproductive power rapidly reducing not only man but also many other species. When fish, frogs, birds, and crocodiles came along with male turtles having male reproductive glands or with undisclosed genitals, it was a rather unusual sight to see them having sex with other male turtles. How, why is this happening? What robs us of our fertility and health of other animals?
