Male Unfertility Rises Sharply In Developed World

Male fertility in the developed world is in sharp decline. A new study from the Hebrew University of Jerusalem shows a 52.4 percent fall in sperm concentration While total sperm count fell 59.3 percent between 1973 and 2011.

Our findings of sharp decline in sperm count among western men is the canary in the coal mine. It signifies that we have a serious problem with the health of men in the western world,” says Hagai Levine, lead-researcher at Hebrew University-Hadassah School of Public Health.

That’s because sperm count is a marker of men’s general health as well as fertility. The study analysed sperm count studies from across the world – and the trend was reflected in America, Europe, Australia and New Zealand. The next step is to investigate the causes of male infertility.
From previous research we know that exposure to man-made chemicals, especially during the critical period of the development of the male reproductive system in pre-natal life, in the early stages of pregnancy can severaly disrupt and can manifest later in life as low sperm count and problems with male fertility,” explains Hagai Levine. The study controlled for factors like age, sexual activity and the types of men, making its conclusions more reliable. “So if, for example, you have 50 studies in one country and they all show the same trend in declining sperm counts, including different counting methods in different groups of men, that makes it much more likely that it’s real” states Prof. Daniel Brison, scientific Director at the University of Manchester (Dept. of Reproductive Health).

The decline shows no sign of slowing. And the researchers say further research is urgently needed – and regulation of the environmental factors that may be contributing could be part of the solution.

Artificial Intelligence Tracks In Real Time Everybody In The Crowd

Artificial Intelligence that can pick you out in a crowd and then track your every move. Japanese firm Hitachi‘s new imaging system locks on to at least 100 different characteristics of an individual … including gender, age, hair style, clothes, and mannerisms. Hitachi says it provides real-time tracking and monitoring of crowded areas.

Until now, we need a lot of security guards and people to review security camera footage. We developed this AI software in the hopes it would help them do just that,” says Tomokazu Murakami, Hitachi researcher.

The system can help spot a suspicious individual or find a missing child, the makers say. So, an eyewitness could provide a limited description, with the AI software quickly scanning its database for a match.
In Japan, the demand for such technology is increasing because of the Tokyo 2020 Olympics, but for us we’re developing it in a way so that it can be utilized in many different places such as train stations, stadiums, and even shopping malls,” comments Tomokazu Murakami.

High-speed tracking of individuals such as this will undoubtedly have its critics. But as Japan prepares to host the 2020 Olympics, Hitachi insists its system can contribute to public safety and security.
