ICSI (Intracytoplasmic Sperm Injection) is an advanced fertility treatment used to assist fertilization by injecting a single sperm directly into an egg.
At Millennium IVF, ICSI is often recommended for patients with specific fertility challenges, particularly related to sperm quality or previous unsuccessful IVF attempts.
Who ICSI Treatment Is For.
- ✦Sperm abnormalities such as low count or poor motility
- ✦Failed fertilization in previous IVF cycles
- ✦Multiple IVF cycles without success
- ✦Eggs with thick outer layers that prevent fertilization
- ✦Infertility linked to genetic conditions
- ✦Unexplained infertility
Similar to IVF — with one key step.
ICSI follows a similar process to IVF, with an additional step during fertilization.
Ovarian Stimulation
Medication supports egg development across an individually-tailored protocol.
Egg Retrieval
Eggs are collected through a minor, monitored procedure under sedation.
Sperm Selection & Injection
A single sperm is carefully injected directly into each mature egg.
Embryo Development
Fertilized embryos are monitored in the lab over several days.
Embryo Transfer
A selected embryo is transferred to the uterus for implantation.
