ICSI
In one sentence
Intracytoplasmic sperm injection places a single selected sperm directly inside the egg during IVF.
Intracytoplasmic sperm injection places a single selected sperm directly inside the egg during IVF.
Why it matters
ICSI transformed severe male-factor infertility: fertilisation no longer depends on sperm swimming and penetrating unaided. For couples without male-factor issues, routine ICSI adds cost without clear benefit — guidelines reserve it for where it helps.
What to ask
If ICSI is proposed, ask what in your results makes it necessary rather than standard insemination.
