Is ICSI better IVF? Only when there is a reason.

PICSI stands for Physiological Intracytoplasmic Sperm Injection: ICSI in which the embryologist picks a sperm that binds to hyaluronic acid.

Hyaluronic acid is found naturally in the layer around the egg. Mature sperm have receptors that let them stick to it, so the embryologist places the sperm on a dish coated with it and picks one that has bound. That sperm is then injected into the egg exactly as in ICSI. The rest of the cycle is the same.

Only the way sperm meets the egg differs. Stimulation, egg collection, embryo growth and transfer are the same in all three.

Here is the plain comparison, and when each one fits.

• Conventional IVF: sperm is placed around each egg in a dish and fertilises it on its own. Fits when the semen analysis is normal and there has been no fertilisation failure before.
• ICSI: the embryologist picks one sperm by its look and movement and injects it into each mature egg. Fits a low count or poor movement, surgically retrieved sperm, frozen eggs, previous fertilisation failure, or embryos going for genetic testing (PGT).
• PICSI: ICSI with the sperm chosen by hyaluronic acid binding. Offered selectively when there is a specific reason [CONFIRM: Dr Vani's indications].

ICSI is not automatically better IVF. It makes fertilisation more reliable when sperm struggles, but for couples with normal sperm, guideline bodies find it does not raise the chance of a baby.

Many couples are told ICSI is simply the better version of IVF. At Jananam we often favour ICSI, because it lowers the risk of an unexpected result where no egg fertilises. It also adds cost and lab handling, so it is a decision made for your case, with the reason in your plan.

For most couples, no: large trials so far have not shown that PICSI raises the chance of a live birth compared with ICSI.

The UK regulator, the HFEA, rates PICSI as an add-on with no effect on treatment outcome, based on moderate to high quality evidence. That is why we do not use it routinely. Where Dr Vani suggests it, she tells you the specific reason [CONFIRM: indications].

Because ICSI solves fertilisation, not sperm quality.

The embryologist still has to choose from the sperm in the sample, and sperm DNA quality affects embryo growth and miscarriage risk. Some causes of a low count can be corrected: varicocele, infection, hormone problems, uncontrolled diabetes or thyroid, some medicines, smoking, alcohol and heat. Sperm takes about 74 days to form, so treatment needs 2 to 3 months before the cycle.

ICSI is widely used and considered safe, with some small added risks that we go through with you before you start.

The needle can damage a small number of eggs. Studies suggest a small rise in some risks for children, partly linked to the sperm problem itself rather than the injection. If a very low count has a genetic cause, a son can inherit it, so genetic tests and counselling are offered first when the count is very low.
