Summary
Intracytoplasmic sperm injection (ICSI) is a groundbreaking micromanipulation technique that successfully treats male factor infertility. This method has led to the birth of healthy children with no increased congenital malformations.
Area of Science:
- Reproductive medicine
- Assisted reproductive technology
Background:
- Male factor infertility presents significant challenges in conception.
- Traditional in vitro fertilization (IVF) has limitations for severe male infertility cases.
Purpose of the Study:
- To describe the intracytoplasmic sperm injection (ICSI) micromanipulation technique.
- To review the historical development and human application of ICSI for male infertility.
Main Methods:
- Extensive experience in animal models is crucial before human application.
- Criteria for patient selection and alternative applications of ICSI are discussed.
Main Results:
- ICSI has become a highly successful treatment for male factor infertility, surpassing initial expectations from animal model studies.
- Numerous healthy children have been born via ICSI with no observed increase in congenital malformations.
Conclusions:
- ICSI achieves high success rates in treating male factor infertility, comparable to standard IVF in non-male factor cases.
- Spermatozoa used in ICSI are typically genotypically normal, suggesting successful selection.
