Regarding humans it is said that most psychological effects caused in men by testosterone are caused in women by estrogens. There are many studies on that, particularly regarding temporary shifts of hormone levels: Ovulatory shift hypothesis. Also, there are some studies (and possibly controversial) claiming such differences between individuals.
But this made me think if there are any similar physiological diffences caused by estrogens. It's known that in males testosterone affects muscular growth, which means higher testosterone levels will make it easier to gain muscular weight. So, I ask if higher estrogen levels in females affect muscular growth.
While this question is regarding humans, studies about other primates also can be acceptable.
