The subject of sexual differentiation into male, or female, during the prenatal, and especially embryonic stage, is still a matter of study and research. Although many of the processes are widely accepted and understood, studies show that there may be other factors involved in sexual differentiation. However, what has been known so far is that in the embryonic stage, the presence of TDF (testis-determining factor) is crucial to this determination. TDF is a product of the presence of the Y chromosome in the gene known as SRY. It has been seen that when this protein product is not presence, there will be no growth of the necessary parts for male differentiation from a female.
