Abstract
Cytogenetic investigations were carried out on 150 individuals. Out of these 107 were females and 43 males. Eighty seven of the above (43 males and 44 females) had been referred for sterility. Sixty three patients had primary amenorrhea and had been referred directly to this laboratory by clinicians, having been suspected of genetic abnormalities. Twenty-two cases (14.7%) involved in this study showed chromosomal abnormalities and seven cases (4.7%) showed chromosomal polymorphism. Of the 107 females (44 sterile and 63 with primary amenorrhea), 11 (10.2%) showed numerical or structural sex chromosomal abnormalities. Five patients (4.67%) showed chromosomal polymorphism involving the paracentromeric and centromeric regions of chromosomes 1 and 9, double satellites, and giant satellites. Of the 43 males, 11 (25.59%) showed numerical and structural abnormalities. Ten cases were anomalies involving the sex chromosomes. One case of a triple autosomal translocation in an otherwise phenotypically normal azoospermic male was of particular interest. Two cases (4.65%) showed double satellites of the acrocentrics.
