Scientists predict men’s extinction again

An Australian scientist told the RCSI’s Annual Out­reach Lecture that the Y chromosome, which determines gender, is dying out, and men could go with it.

Prof Jennifer Graves warned the genetic make-up of the chromosome has declined significantly over the years, remarking the Y chromosome has lost all but 45 of the 1,400 genes that were on it 300 million years ago.

While the outlook is not great for the future of men, other species have survived the decline of the gender-defining Y chromosome and SRY gene.

“The good news is that certain rodent species have no Y chromosome and no SRY gene, yet there are still plenty of healthy males... some other gene must have taken over the job, and we’d like to know what that gene is.

“We already know that there are several candidate genes out there that could take over from SRY. However, which one takes over is sheer chance, imn.ie reports.

"It’s even possible that two or more different sex-determination systems based on different genes could arise two different populations,” Prof Graves said.

Pravda.Ru previously published a number of articles about male extinction.

“According to Sergey Shnurov, a frontman of the popular Russian punk group Leningrad, a real man “got balls, a stubbly chin, and he smells of tobacco and hangover. Too true, the criteria are unlikely to fit a guy with carefully manicured fingernails and conspicuously gelled haircut, the one who walks past the shop windows leaving a trail of Givenchy perfume. The guy looks like a metrosexual.

I am not talking about those who opt to get laid while traveling by metro. The term “metrosexual” is a combination of two words, metropolis (Gk – a chief city) and sexual. Not unlike any other noticeable phenomenon, metrosexuality is often accompanied by myths and speculations.

“It the good old 19th century, nobody thought a dandy could be gay.”

In another article Pravda.Ru reported about the extinction of Russian men in some regions of Russia.

Russian Ministry for Health Care reported the statistics concerning death rate among able-bodied men in Russia. As it turned out, Russian men of this age category die 4 times oftener than women of the same age category. As for other age categories, the death rate among men is also higher than among women. The average life expectancy of Russian men makes up 58-59 years today, which is 14-15 years less than the life expectancy of Russian women or men from developed countries.

Researchers from the Moscow State University state that life expectancy in Russia at the end of the 19th – at the beginning of the 20th centuries was 15-20 years less than life expectancy in Europe. We should give the Soviet power credit for its efforts as a result of which infant mortality and mortality caused by infections reduced before WWII. The positive effect was favorable for men particularly. Indeed, although the number of newborn boys is higher than the number of newborn girls everywhere in the world, but infant mortality among boys is always higher.

Male losses caused by the Great Patriotic War have not been yet calculated precisely. By the mid-1960th, the life expectancy in the Soviet Union reached approximately the same level that in the West (Soviet men lived for 64.5 years on average and European and North American men lived for 66 years). But later the death rate among Soviet able-bodied men considerably increased because of heart diseases, cancer and other injuries.

Demographers explain the problem with the poor level of Soviet medicine and ignorance of Soviet men concerning their health. On the other hand, the Soviet Union was one of the first countries that started total clinical examination of workers, students and school pupils for the sake of successful prophylaxis. Later, the system was successfully applied in the West.
