Summary
Intracytoplasmic sperm injection (ICSI) is effective for male infertility, with no increased risk of developmental issues or congenital defects in children. Genetic screening is recommended for couples undergoing ICSI.
Area of Science:
- Reproductive Medicine
- Genetics
- Pediatrics
Background:
- Intracytoplasmic sperm injection (ICSI) is a primary treatment for male factor infertility.
- Concerns exist regarding genetic defect transmission and developmental outcomes in ICSI-conceived children.
Purpose of the Study:
- To evaluate the clinical outcomes of ICSI at Cornell University.
- To screen ICSI parents and children for genetic defects and assess child development.
Main Methods:
- Analysis of pregnancy, obstetrical outcomes, and congenital malformations.
- Chromosomal karyotyping and Yq deletion assessment.
- Longitudinal assessment of medical and developmental outcomes in ICSI children at ages 3 and 5.
Main Results:
- High fertilization (75.4%) and pregnancy (42.8%) rates with ejaculated sperm; 66% fertilization and 48.8% pregnancy rates with surgically retrieved sperm.
- Yq deletion incidence was within expected ranges for infertile populations, with transmission to male offspring.
- No significant differences in cognitive, motor, or behavioral development were observed between ICSI children and naturally conceived children.
Conclusions:
- ICSI effectively treats male infertility and does not increase the incidence of de novo genetic deletions.
- ICSI children show no increased risk of congenital defects or lower psychomotor development compared to naturally conceived children.
- Genetic screening and counseling are advised for couples undergoing ICSI.
