Artificial Oocyte Activation (AOA)
A laboratory technique that helps eggs fertilise normally when previous cycles had low fertilisation.
- Rescues low-fertilisation cycles
- Used in carefully selected cases
- Paired with ICSI
About this treatment
Sometimes, even after ICSI, eggs fail to fertilise as they should. Artificial Oocyte Activation (AOA) is a specialised lab technique that gives the egg the chemical 'activation' signal it needs to begin developing into an embryo.
We use AOA in carefully selected cases — typically where a previous cycle had a very low fertilisation rate — to materially improve the chance that injected eggs go on to fertilise and form healthy embryos.
Who it's for
- Total or very low fertilisation in a previous ICSI cycle
- A suspected egg-activation deficiency
- Severe male-factor cases after ICSI
Key benefits
- Can markedly improve fertilisation rates
- Helps couples after a failed-fertilisation cycle
- Targeted, evidence-based use

Oocyte Activation (AOA) — your questions
Common questions about this treatment. Anything else? Our team is happy to talk it through.
Mainly when a previous ICSI cycle resulted in very low or zero fertilisation despite good eggs and sperm — a sign the egg may not be activating normally.
It's used selectively and only where clinically indicated. Your specialist will discuss whether it's appropriate for your situation.

Figures shown are measured per embryo transfer at our Solapur centre — a beta-hCG positive (pregnancy-test) rate and a live-birth rate; a positive test is an earlier milestone than a live birth, and any comparison figures for other centres are their own publicly advertised numbers, which may be measured differently.
