Sperm counts are at risk of dropping as the planet heats up, according to a team of scientists. Reproductive cells are already known to be affected by heat, but the findings from researchers in Singapore give more detailed insights into how climate change could impact fertility rates. Men who were exposed to extreme heat in the three months prior to providing a semen sample had a 46 per cent higher chance of a low sperm count, they found. The risk of a low sperm concentration also shot up by 40 per cent, and the ‘little swimmers’ were notably more sluggish. Do organic farms cause unintended ha...

Scientists in Israel have managed to create artificial testicles in what could be a significant step in helping men with fertility issues. The testicles, or testes, are responsible for sperm production and androgen synthesis which play a part in male sexual development. Infertility affects up to 7 per cent of men. Currently, no in vitro system exists for modelling the testis and producing sperm in the same way that IVF treatment can harvest eggs from a female. “Artificial testicles are a promising model for basic research on testicle development and function, which can be translated into thera...
