Testosterone levels are negatively associated with fatherhood [corrected] in males, but positively related to offspring count in fathers.

Variation in testosterone (T) is thought to affect the allocation of effort between reproductive and parenting strategies. Here, using a large sample of elderly American men (n = 754) and women (n = 669) we examined the relationship between T and self-reported parenthood, as well as the relationship...
