<unk> s are not often detected before delivery. Most<unk> s are found during surgery if a caesarean section is performed or when some other surgery is performed. Pre-delivery detection is not effective for many reasons. Some tests, that can be performed pre-delivery, measure the amount of testosterone in the blood; however, this is not a very useful detection method since normal pregnancies have increased amounts of testosterone. Another method that would be useful to determine if a fetus is being exposed to testosterone is to test the placenta and umbilical cord for testosterone. The placenta has a mechanism for converting hormones from the mother into hormones that the fetus needs. If the amount of testosterone in the umbilical cord is higher than normal, the gene type of the fetus should be determined to see if the fetus is male or female. If the fetus is female then the high levels of testosterone in the umbilical cord could be an indicator that a<unk>  is present. Unfortunately, this procedure can't be safely performed until after the fetus has undergone differentiation (when the sex of the fetus becomes apparent). But by this time the damage has already been done.
