When a semen analysis comes back with low numbers, or an earlier IVF cycle did not lead to fertilised eggs, many couples in Vizag are told about ICSI treatment for the first time. The term sounds technical, and searching online often brings more confusion than clarity, with cost claims and percentages that rarely explain what actually happens.
This guide explains ICSI in plain language: what it is, how it differs from IVF, who may need it, each step of the process, the risks, and the questions worth asking any fertility clinic.
Quick answer: ICSI (intracytoplasmic sperm injection) is a laboratory step within IVF in which an embryologist injects a single sperm directly into each mature egg. It is mainly used when sperm count, movement or shape is low, when sperm has been retrieved surgically, or when eggs did not fertilise in a previous IVF cycle. The rest of the treatment follows the same steps as IVF.
ICSI stands for intracytoplasmic sperm injection. "Intracytoplasmic" means "into the inside of the egg cell". In normal conception, and in conventional IVF, a sperm has to swim to the egg and break through its outer layer by itself. In ICSI, an embryologist uses a very fine glass needle under a powerful microscope to place one sperm directly inside the egg.
The UK fertility regulator, the HFEA, explains that ICSI is carried out as part of IVF. In other words, ICSI is not a separate treatment. The woman still goes through ovarian stimulation, egg collection and embryo transfer, and only the fertilisation step in the laboratory is different.
Good to know
This is one of the most searched questions about the procedure. The simplest answer is that the difference lies in how fertilisation happens in the lab.
In conventional IVF, eggs are placed in a dish with thousands of prepared sperm, and fertilisation happens naturally. In ICSI, one sperm is chosen and injected into each egg. You can read more about the full IVF process (padmasrihospitalsandivfcentre.com/in-vitro-fertilization.php) on our website. Your fertility doctor will recommend one method or the other, or occasionally a mix of both, based on your test results.
According to the HFEA, ICSI is mainly recommended for male factor infertility and a few specific situations:
The HFEA notes there is no evidence that ICSI improves results for couples without male factor infertility, and that it is unlikely to help when the problem is with egg quality or immature eggs. This is a useful reminder: ICSI should be recommended because your tests suggest it is needed, not as a routine "upgrade".
The decision usually starts with a semen analysis, which looks at sperm count, movement and shape. The female partner is also evaluated with hormone tests and an ultrasound scan to check the ovaries and womb. Sometimes further tests, such as hormone or genetic tests for the male partner, are advised.
Because ICSI is part of IVF, a full cycle typically takes around four to six weeks from the start of injections to the pregnancy test, although your own schedule may differ.
From the woman's side, ICSI is exactly the same as IVF. Injections can cause mild bloating or tenderness. Egg collection is done under sedation, and most women feel some cramping for a day or so afterwards. The extra ICSI step takes place entirely in the laboratory.
ICSI is widely used around the world, but like any medical procedure it has some risks, which your doctor will explain before you consent.
| Risk | What it means |
|---|---|
| Egg damage | A small number of eggs may be damaged by the injection and not develop. |
| IVF-related risks | Ovarian hyperstimulation syndrome (OHSS) from the hormone injections, and risks from egg collection such as bleeding or infection, which are uncommon. |
| Multiple pregnancy | Transferring more than one embryo raises the chance of twins, which carries more risk for mother and babies. Single embryo transfer reduces this. |
| Health of children | The HFEA notes a small possible increase in some genetic or developmental conditions in children born after ICSI. This may relate to the underlying infertility rather than ICSI itself. |
| Inherited causes | If male infertility has a genetic cause, it may be passed on to the child. Genetic counselling may be suggested. |
| Emotional strain | Treatment can be stressful. Counselling and support are part of good care. |
Key points so far
Two of the most common questions about this treatment are about cost and outcomes. Both depend heavily on individual factors such as age, the cause of infertility and the number of cycles, so a single number online means very little. A better approach is to ask any clinic you consider for clear, written answers:
These questions help you compare clearly, understand your plan, and make the decision that is right for both of you.

In conventional IVF, eggs are mixed with many sperm in a dish and fertilisation happens on its own. In ICSI, an embryologist injects one sperm into each mature egg. All other steps, such as stimulation, egg collection and embryo transfer, are the same.
ICSI is mainly used for male factor infertility, such as a very low sperm count or poor sperm movement or shape, when sperm is retrieved surgically, when eggs did not fertilise in a previous IVF cycle, or with frozen sperm or eggs.
For the woman, ICSI feels the same as IVF. The injections may cause mild bloating, and egg collection is done under sedation, with some cramping afterwards for most women. The ICSI step itself happens in the laboratory.
A full cycle usually takes around four to six weeks, including about 10 to 14 days of hormone injections, egg collection, three to five days of embryo culture, transfer and a pregnancy test about two weeks later.
Most children born after ICSI are healthy. The HFEA notes a small possible increase in some genetic or developmental conditions, which may be linked to the underlying infertility. Your doctor can explain this and arrange genetic counselling if needed.
No. ICSI helps fertilisation happen when sperm cannot fertilise the egg on their own, but pregnancy also depends on egg quality, embryo development, the womb and age. No fertility treatment can promise a pregnancy.
