Would the size of the testicles affect the men and their paternity? A recent American study, conducted by a team of anthropologists at Emory University in Atlanta, answers this question positively. According to this survey, conducted at 70 men whose children were 1 to 2 years old, males with smaller testes would be more likely to engage in parenting tasks, such as changing diapers, bathing, or bottle feeding. How did they come to such conclusions? Very simple: the researchers have decrypted various brain scans, passed on the 70 men required for this survey, when looking at pictures of their children. Result: for men with larger testicles, stimulation of the brain's reward system was well below men having smaller testicles. An area of ​​the brain that, once stimulated, provides the motivation to perform appropriate actions and behaviors, to preserve the individual and the species. In other words, it is important to stimulate it, in the presence of a childto make the necessary gestures for survival. Understand here: feed him, wash him, change him.
"It tells us that some men are more naturally inclined to take care of and care for their children that others. This does not excuse others. It may require more effort to some than to others " summarizes James Rilling, a member of the anthropology team behind this survey. According to the researchers, the size of the testes, probably related to testosterone, would therefore affect the behavior. That would not be, however, the only factor. Cultural and social expectations were not taken into account during this survey. Similarly, men interviewed were all from the Atlanta area. It is therefore not representative of all men living on earth.
