No, the weight of the brain is not same in male and female. The weight of the brain in female is approximately 1400 and in male is 1600.

Your brain itself, the physical organ, isn't particularly differentiated. The male/female changes in the brain are more caused by living in a body that has generated male or female hormones; testosterone or progesterone. Every body has both hormones; it's the balance that is important.

So if you're male, you have a brain more influenced by male hormones; if you're female, your brain is more influenced by female hormones.

There is no "sex" in brains.

Because on average males are larger than females in our species, male brains on average are larger. However, a given male brain when compared to a given female brain can certainly be smaller.
