Researchers studying 22 male chimps in Uganda's Kibale National Park found that males with more testosterone also had more parasites living in their stomachs, .
Male chimps compete aggressively for dominance, like most primates, and testosterone aids in this aggression. After collecting fecal samples from the chimps in Uganda, researchers found, predictably, that the higher-ranking males had more testosterone, but that they also had apparently suppressed immune systems that allowed parasites greater reign. Their findings suggest that testosterone may play a role in the weakened immune systems.
Looks like we guys at 国产吃瓜黑料 may want to tame our manliness a bit, if it can be done. But I doubt it. Immune systems are for sissies.
