I think is a trend. There are several studies that have shown that human sperm production has been decreasing since decades ago compartin studies from. 60s. 70s, 90s, and so on. So I think that conspiracy theories about silent methods to decrease human population are real. Methods such as chemical endocrin disruptors, in food, hormones, toxines, pollution, and a big, etc. Besides life style nowadays is very diferent from decades ago. We spend less time doing phisical activities sunrays exposition, stress, etc. Lack of comprehension of male body in their sexual behavior, being afected by habits like watching lots of porn and jerking too often. I could assure that there are lots of young males that never realized or tried themselves to produce more semen or how to control their climax better because of the habit of a quick jerk and they have more porn than information. Just some thoughts and opinions from my obervation.
