Frequency of acrocentric association in abnormal sexual development in males and females

A significant difference (P less than 0.05) was observed in a chi 2 comparison of DD, GG and DG-DI associations between male hypogonads and females with primary amenorrhea. This difference increased still further (P less than 0.01) when only DD and GG associations were compared between males and females with abnormal sexual development (ASD). Similarly, when normal males and females were compared for DI, TRI, TETRA, DD vs GG and DG vs GG acrocentric chromosome associations, a significant difference (P less than 0.05) was again observed. The sex difference was also apparent in TRI and TETRA acrocentric associations both in abnormal and normal sexual development males and females. These results suggested that probably sex difference (may be hormonal) influences the number and/or type of acrocentric chromosomes involved in association between males and females with ASD and also between normal males and females.
