Existing study is conflicting. Further research into testosterone substitution are necessary for doctors to fully have an understanding of its likely hazards and benefits, and to establish the folks which will see one of the most benefit.

When an embryo lacks a Y chromosome and therefore the SRY gene, ovaries acquire. Fetal ovaries never deliver adequate quantities of testosterone; So, the Wolffian ducts don't develop. There's also an absence of MIS in these folks, leading to the event with the Mullerian ducts and feminine reproductive buildings.[one]
