Sex development is a complex process, and there are many different variations that can happen on the way. A good way to think about this is to imagine how babies in the womb follow different paths to develop. Some of the most common reasons for a DSD are congenital adrenal hyperplasia (CAH), peno-scrotal hypospadias, hormone imbalances or variations in the baby’s chromosomes. In most circumstances your expert team will be able to discuss a clear way forward with you quite quickly and you can get on with enjoying your baby at home. In the months that follow there may be follow-up visits with your team to talk further and think about the medium to long term care of your baby.
