Comments to K.E. Wynne-Edwards and M.E. Timonin 2007. Paternal care in rodents: Weakening support of hormonal regulation of the transition to behavioral fatherhood in rodent animal models of biparental care, Horm & Behav 52: 114-121.

چکیده
In an earlier issue of Hormones and Behavior, WynneEdwards and Timonin reviewed more than one decade of studies on the endocrinology of paternal care in male rodents (WynneEdwards and Timonin, 2007). While most studies demonstrated correlations between being a father and hormone levels, especially Wynne-Edwards and co-workers also conducted important experiments during the last years to test for a causal relationship. However, the conclusions of Wynne-Edwards and Timonin are rather negative: (1) “The co-variation between hormones and paternal care is not causal” (abstract); (2) “The hypothesis of homology between maternal and paternal neuroendocrine circuits is false” (p. 120). Here I want to argue that these conclusions are too early, and that more detailed and especially more complex studies are needed. In addition, I think that the following important question has to be approached: “Why do rodent fathers show changes in hormone levels?”.
