Studies of SF1 have resulted in less definite results. Advances in Genetics Vol Various methods were used in determination of age. SRY encodes a protein that controls the concentration of dopaminethe neurotransmitter that carries signals from the brain that control movement and coordination.

It's not the Y chromosome itself that determines whether a baby is male or female, but rather a particular region called the SRY gene.

During gestation, the cells of the primordial gonad that lie along the urogenital ridge are in a bipotential state, meaning they possess the ability to become either male cells Sertoli and Leydig cells or female cells follicle cells and Theca cells.
Additionally, cells expressing TDF will continue to proliferate to form the primordial testis. From Wikipedia, the free encyclopedia.
Age and sex determination
Animated Explanation Video - Duration: Offspring which inherit this Y chromosome will have Swyer syndromecharacterized by an XY karyotype and a female phenotype. There is evidence from work on suppression of male development that DAX1 can interfere with function of SF1and in turn transcription of SRY by recruiting corepressors.
These cords form in the central part of the yet-undifferentiated gonadturning it into a testis.

An additional copy of DAX1 in mice leads to sex reversal. While the presence or absence of SRY has generally determined whether or not testis development occurs, it has been suggested that there are other factors that affect the functionality of SRY. It also works towards developing the dominant male characteristics.
More reference expression data.
Individuals who inherit a normal Y chromosome and multiple X chromosomes are still male such as in Klinefelter syndromewhich has an XXY karyotype.
Transcription factors and intracellular receptors.
Embryos are gonadally identical, regardless of genetic sex, until a certain point in development when the testis-determining factor causes male sex organs to develop.
