No, go into the link I provided. The brain will only change if it is bathed with androgen. If it is not, then it continues as a female brain. Now there are many case scenarios that take place. Let say we have a fetus with XX chromosome, but the sry gene has incorrectly been attached to the X chromosome you will then, have an androgenic affect. Which means now a female protype will develop as male even though they have female DNA. Another scenario is the pregnant mother was given medication which altered the uteral enviroment, created excess androgen, the fetus brain will be altered.
So, you cannot go by the chromosomes, there are many females who are XY, as there are many males who are XX. It's all about the hormones and timing. Female is the original one according to science and the latest research.

Sorry about not seeing the video, but they take so long to download I try to avoid them.
I have (you'll be surprised to hear) studied genetics to a small degree, although I did avoid development as much as I could. However, I do know enough to know about various problems with the male development at this stage.
I was making more of a point about semantics: default does not mean original. It does not say anything about the status of the brain before the time of the signal. Until the time for the signal, the brain is neither male nor female.
It then reaches a fork; it can become either male or female. The fact that an active signal is required for it to become male does not make it female before that point. As even the (very opinionated) article to which you linked previously admitted, further development occurs to make it a female brain.
