However, these cells are prone to become cancerous cells. In these cases, the abnormal gonads are totally removed. Complete gonadal dysgenesis is the most severe form of nonfunctional gonads in XY females. The severity of the case is a result of when the defect began and how harsh the defect is. If testicular development proceeds farther than in cases of complete gonadal dysgenesis, gonads may develop that have some testicular tissue.
Many syndromes are the result of XY females.
Several syndromes will be briefly discussed in this essay. The X-Y interchange hypothesis states that at meiosis in the male, interchanges between pairing areas of the X and Y chromosomes could produce a X chromosome that contains some Y material or a Y chromosome that contains some X material. This interchange between the X and Y chromosome could take place because of irregular delay of the two chromosomes. To test this X-Y interchange, Disteche et al. performed tests on two patients. Patient one has only a few Turner syndrome characteristics, and patient two has several attributes of Turner syndrome.
