I'm not aware of any studies comparing the thyroid gland between the sexes. The situation with the pituitary is a bit more complicated. Many studies have reported differences between the male and female hypothalamus (which largely controls the pituitary). For example, the so-called sexually dimorphic nucleus of the anterior hypothalamus is, if I recall correctly, typically larger in males. There appear to be other areas of the brain that differ between the sexes, including some cortical areas.
Could those differences account for some differences in behavior? Potentially. But (and please excuse the bad pun), this may be a case where size doesn't matter, but what matters is the functioning of the cells in those areas.

If so, can that difference partially explain the different behaviors we see in men & women? I realize that it won't be a complete explanation but we are in the biology chapter and hence thinking from a neuroscience perspective. Thanks in advance for your help J.
