Global warming can adversely affect male fertility. Because of the heat waves seriously damaged spermatozoa, as the study showed.
Global warming poses a risk to male fertility, warn researchers. They found that heat waves give rise to serious long-term damage to spermatozoa. The study showed that the male insects fertility was significantly reduced at the time when the temperature even for a short period grow above average indicators. Exposing beetles a five-day heat when the temperatures are above normal by 5-7 degrees, the researchers found that the number produced by the insects of sperm has decreased by half. A second heat wave is almost sterilized males. When this female insect from the heat was not injured.
Scientists from the University of East Anglia believe that the process of sperm production is particularly sensitive to temperature changes. This may explain why, due to changes in climate occur such a noticeable change in the animal world. Published in the journal Nature Communications, the study also showed that conceived in the heat of the offspring of the insects later turns out to be less fertile and live for a few months less than their parents. A few months a bug’s life is equivalent to several years of life.
The researchers emphasize that the insects in nature are quite often faced with the impact of multiple heat waves. This becomes a problem for their reproduction if males do not have time to adapt to climate changes or to recover. All the same can be observed in humans. (READ MORE)
