Prenatal Cytogenetic Analysis of 145 Fetuses Conceived by Intracytoplasmic Sperm Injectiion ( ICSI )


Prenatal diagnoses were performed in 145 fetuses resulting from 73 singleton and 36 twin pregnancies, all established by intracytoplasmic sperm injection (ICS: amniocentesis in 108 patients and Chorionic villus sampling in one. The prenatal cytogenetic results were obtained from pregnancies after ICSI using ejaculated spermatozoa, epididymal spermatozoa, testicular spermatozoa and after the replacement of frozen-thawed embryos derived from ICSI. The Karyotypes were normal in 138 cases (95.2%) of the prenatal diagnoses and there were 2 cases (1.4%) de novo and 5 cases (3.4%) inherited chromosomal aberrations. The two cases of de novo abnormalities were: 46, XY, t(6;7)(q21;p22) and 47, XY, +21 (trisomy 21).
