Seven of 9 patients had been raised as females, of which the chromosomal karyotype was 46XX in 5 cases, 46XX/46XY and 46XX/47XXY in 2 cases. Two of 9 pa- tients were raised as males, the chromosomal karyotypes being 46XX and 46XX/46XY. All 9 patients had testicular tissue excised, and biopsies of the conserved ovarian tissue were performed. Ovotestis was the most common form of the abnormal gonads; two of 9 patients had bilateral ovotestes, seven had unilateral ovotestes (5 in right side, 2 in left side). In seven patients with a unilateral ovotestis, 6 had a contralateral ovary and one had a contralateral testis. Microscopically, the ovarian tissue of 11 ovotestes, including 6 biopsies from contealateral ovaris, were normal, with many primordal follicles and a few growing follicles. In two of the patients, aged over 15 years, evidence of ovulation was observed. In comparison, the testicu- lar tissue of the ovotestis and the one left inguinal testis was histologically abnormal, with immature semi- niferous tubules, most of which filled with Sertoli cells only. Three of 9 patients married after surgical treatment. Two of these subsequently conceived and delivered of normal infants by cesarean section.展开更多
