Abstract

OBJECTIVE
To analyze the obstetric outcomes, the incidence of congenital malformations and chromosomal anomalies of neonates born after intracytoplasmic sperm injection (ICSI) according to the origin of sperm.
METHODS
A total of 103 neonates born from ICSI between January 1995 and January 2004 was included. They were divided into three groups: ejaculated (n=73), epididymal (n=17) and testicular (n=13) groups. We compared obstetric outcomes such as pregnancy rates, preterm birth rates, abortion rates, multiple pregnancy rates, gestational age at birth, birth-weight, and the incidence of congenital malformations and chromosomal anomalies.
RESULTS
There were no differences among the three groups in terms of pregnancy rates, preterm birth rates, abortion rates, multiple pregnancy rates, gestational age at birth and birth-weight. There were no differences in the incidence of low birth-weight babies and very low birth-weight babies. Major malformations were observed in two cases of ejaculatory group (2.7%) and one of testicular group (7.7%). Major malformations included two gastrointestinal malformations and one cleft lip. Minor malformations were observed in three cases of ejaculatory group (4.1%) and one of testicular group (7.7%). Chromosomal anomalies were observed in 6 cases of 105 pregnancies (5.7%), and all of them were from the ejaculatory group. Two cases had autosomal numerical anomalies and 4 cases autosomal structural anomalies. However, sex chromosomal anomalies were not detected in this study.
CONCLUSION
The obstetric outcomes, the incidence of congenital malformations and chromosomal anomalies in ICSI babies were not different according to the origin of sperm. These findings should be further investigated in larger long-term studies.
