Abstract
Objective To compare the karyotype of babies conceived through ICSI with that of naturally conceived babies.
Design Prospective controlled study.
Setting The Egyptian IVF-ET Center, Cairo, Egypt.
PATIENT(S): Four hundred and thirty babies conceived through ICSI and 430 babies conceived naturally.
INTERVENTION(S): ICSI and karyotyping.
MAIN OUTCOME MEASURE(S): Abnormal karyotype.
RESULT(S): Four hundred and thirty consecutive babies conceived through ICSI who were delivered in one hospital had 15 abnormal karyotypes (3.5%). Of the 15 babies, 7 were of female phenotype and 8 of male phenotype. Six babies had sex chromosome anomalies, 8 had autosomal anomalies, and 1 had combined sex chromosome and autosomal anomalies. A control group of 430 consecutive babies conceived naturally who were delivered in one hospital had no abnormal karyotype. The difference between the two groups was significant (P<.001).
CONCLUSION(S): ICSI carries a small but significant increased risk of abnormal karyotyping to the offspring. This risk appears to be equally distributed between autosomal and sex chromosome anomalies.
