Intracytoplasmic Sperm Injection (ICSI) is a highly advanced form of assisted reproductive technology (ART) used in conjunction with IVF. In this procedure, a single healthy sperm is carefully selected and directly injected into a mature egg under a high-powered microscope to achieve fertilization.
ICSI has revolutionized the treatment of severe male infertility and is especially beneficial for couples who have experienced repeated IVF failures, poor fertilization, or significantly abnormal semen parameters. The procedure requires an advanced embryology laboratory and highly skilled fertility specialists.
Who should consider ICSI treatment?
ICSI is recommended in the following clinical situations:
Severe Male Factor Infertility
Extremely low sperm count, poor motility, or abnormal sperm morphology can be effectively managed with ICSI.
Previous IVF Fertilization Failure
When conventional IVF fails to achieve fertilization, ICSI significantly improves fertilization rates.
Surgical Sperm Retrieval Cases
ICSI is ideal when sperm is obtained through TESA, TESE, or PESA procedures.
High DNA Fragmentation
Advanced sperm selection techniques combined with ICSI improve outcomes in men with high DNA fragmentation.
Step-by-step ICSI procedure
ICSI follows all initial steps of IVF, with an additional micromanipulation stage for fertilization.
Ovarian Stimulation & Egg Retrieval
The ovaries are stimulated with hormonal medications, followed by egg retrieval under ultrasound guidance.
Sperm Selection
A single healthy sperm is selected under high magnification for optimal fertilization.
Microinjection Fertilization
The selected sperm is directly injected into the egg using advanced micromanipulation techniques.
Embryo Culture & Transfer
Fertilized embryos are cultured and a healthy embryo is transferred into the uterus.
Success rates & advanced ICSI care
ICSI offers fertilization rates of up to 70–80% per injected egg. Pregnancy success depends on female age, egg quality, embryo development, and uterine receptivity. When combined with advanced IVF protocols, ICSI significantly improves outcomes in challenging fertility cases.
