Male factor infertility is a significant contributor in a meaningful share of fertility cases, and Intracytoplasmic Sperm Injection (ICSI) is the treatment most directly built around it.
What ICSI actually does
Standard IVF fertilization relies on sperm reaching and penetrating the egg on its own in a lab dish. ICSI bypasses that step entirely — an embryologist selects a single healthy-looking sperm and injects it directly into the egg. This matters specifically for cases involving low sperm count, poor motility, or abnormal morphology, where standard fertilization odds are meaningfully lower.
ICSI addresses the fertilization step specifically — it doesn't change embryo quality, implantation odds, or any factor downstream of successful fertilization. It solves one specific problem very effectively.
When it's recommended
- Diagnosed low sperm count, motility, or morphology issues on a semen analysis
- Prior IVF cycles with unexpectedly poor or failed fertilization using standard methods
- Cases using surgically retrieved sperm (for men with no sperm in ejaculate due to a blockage or other cause)
How it fits into your cycle
ICSI is an added lab step, not a separate procedure requiring extra visits — it happens on the same day as standard egg retrieval and fertilization, adding a modest cost to the cycle without changing your overall trip timeline. See our full cycle timeline for how this fits.
A note on the diagnostic workup
A thorough semen analysis before treatment begins is what actually determines whether ICSI is recommended for your case — this should happen early in your consultation process, ideally before you're finalizing travel dates, so your protocol and cost estimate reflect your actual diagnosis.
