translated from Spanish: Climate change could affect male fertility

according to a study in the scientific journal Nature climate change could lead to a threat to male fertility. The research of the University of Anglia East, England, determined that heat waves cause damage in the sperm of insects, which could explain the impact that climate change is having on the population of various species, and even the extinction of some of them. Matt Gage was the professor who led a team that studied how reacted males red flour beetles to simulated heat waves, and analyzed the potential damage to their reproductive capacity. Within what found attention that with a first wave of heat was reduced to half the number of offspring of insects, whereas a second wave went sterile males. They also found that sperm production was reduced in three quarters and that was achieved to produce not migrated well into the female reproductive tract and had less chance of reaching fertilization. The investigation also showed that the frequency of reproduction of the insects was reduced by half after being exposed to high temperatures. On the other hand, the offspring of parents who had been exposed to heat waves lived less time and their reproductive capacity was also affected. With these results the researchers hope to produce in future conservation action plans.
