Summary
Intracytoplasmic sperm injection (ICSI) has revolutionized male infertility management, enabling fertilization by injecting sperm directly into eggs. This technique offers successful outcomes for severe cases and previous IVF failures, even using sperm from the epididymis or testes.
Area of Science:
- Reproductive medicine andrology
- Assisted reproductive technologies
Context:
- Male infertility presents significant challenges in conception.
- Traditional in vitro fertilization (IVF) may fail in severe cases.
- Donor sperm has been a primary option for certain male infertility diagnoses.
Purpose:
- To describe the technique and applications of intracytoplasmic sperm injection (ICSI).
- To review the success rates and outcomes of ICSI.
- To discuss the potential risks and benefits of ICSI in male infertility management.
Summary:
- Intracytoplasmic sperm injection (ICSI) involves injecting a single sperm into an egg for fertilization.
- It is indicated for severe male sterility (e.g., oligoasthenospermia) and recurrent IVF failures.
- Successful fertilization and pregnancy rates have been achieved, including with sperm retrieved from the epididymis or testes.
Impact:
- ICSI offers a viable solution for most male infertility cases previously requiring donor sperm.
- While risks like genetic defect transmission exist, reported malformations and chromosomal anomalies are low.
- Long-term outcomes of ICSI are still under investigation.
