Rilling and his co-authors wanted to see if they could figure out why some fathers opt out of their kids’ lives — the number of absent fathers, the study notes, increased “precipitously” in the latter half of the 20th century. Was there some biology involved? Testosterone is one factor, but it can vary widely in a guy because of age or diet or general health. “Testicular volume is likely to be a more stable measure than testosterone,” says Rilling. |
