Anorchia
From Wikipedia, the free encyclopedia
Anorchia, is a medical condition where both testes are absent at birth. Within a few weeks of fertilization, the embryo develops rudimentary sex organs, which are crucial to the development of the reproductive system. In the human male, if these fail to develop within 8 weeks, the baby will have female genitalia (see Swyer syndrome). If the testes are lost between 8 and 10 weeks, the baby will have ambiguous genitalia when it's born. However, if the testes are lost after 14 weeks, the baby will have a normal male reproductive system, other than the absence of testes.
Individuals with this condition have a 46,XY chromosome constellation.
Other names for anorchia include
- congenital anorchia
- vanishing testes syndrome
- vanishing testes
- empty scrotum
- testicular regression syndrome (TRS)
