A common parasite can decapitate human sperm − with implications for male fertility
A common parasite can decapitate human sperm − with implications for male fertility Male fertility rates have been declining over the past half-century, with a recent study finding that male infertility rates increased nearly 80% from 1990 to 2019. A common single-celled parasite called Toxoplasma gondii may be contributing to this trend, as it can infiltrate […]

But over time, the microbes responsible for these infections have evolved to evade the very drugs designed to eliminate them. Each year, […]
