ICSI (Intracytoplasmic Sperm Injection) is an advanced form of IVF in which a single, best‑quality sperm is directly injected into a mature egg using a fine glass needle under a powerful microscope. This micromanipulation technique is especially helpful when the sperm count is low, sperm movement is weak, or sperm cannot fertilise the egg on their own.
In standard IVF, many sperm are placed around each egg and fertilisation happens naturally in the lab dish. In ICSI, our embryologist actively selects one healthy‑looking sperm and injects it into the egg, which reduces the risk of fertilisation failure, particularly in cases of severe male factor infertility.
BabyGen IVF offers advanced ICSI treatment in Pune and Gurgaon for severe male infertility, low sperm count and IVF fertilisation failures. Know ICSI procedure, cost, success rates and risks.
ICSI is most commonly recommended when there is significant male infertility, such as:
Because ICSI needs only a small number of active sperm, it gives many men a chance to father their biological child even with very poor semen parameters.
ICSI is also used when sperm are obtained surgically from the testis or epididymis, such as TESA, PESA or micro‑TESE. In such situations, the sperm count is limited, so ICSI is the preferred method to maximise fertilisation potential.
Sometimes couples have normal tests but fail to get fertilisation or good embryos in standard IVF cycles.
In these cases, ICSI may be advised in the next cycle to reduce the risk of total fertilisation failure and improve the chance of forming embryos.
When egg numbers are very limited due to low ovarian reserve or advanced maternal age, ICSI helps ensure that each available mature egg gets the best chance to be fertilised.
Because of this direct injection, ICSI needs fewer sperm and lowers the risk of complete fertilisation failure compared to conventional IVF, especially in male factor infertility. However, the choice between IVF and ICSI is individualised; your fertility specialist will recommend the most appropriate method after reviewing your reports.
Before starting ICSI, it is important to optimise thyroid, sugar levels, weight and any chronic medical conditions. Lifestyle steps like quitting smoking, limiting alcohol, eating a balanced diet, exercising moderately and managing stress improve both egg and sperm quality.
Carry previous semen analyses, hormonal reports, ultrasound scans and any past IVF/ICSI records. Prepare a list of questions around fertilisation chances, expected number of embryos, cost breakdown and how many cycles may realistically be needed.
The ICSI procedure follows the same initial steps as IVF, with an extra micromanipulation step in the lab.
At BabyGen IVF, your ICSI journey begins with a detailed consultation and evaluation of both partners. This includes medical history, physical examination, ultrasound scans, hormone tests (such as AMH) and a comprehensive semen analysis, along with any advanced tests like sperm DNA fragmentation where needed.
The female partner receives fertility injections for around 9–12 days to stimulate the ovaries to produce multiple eggs instead of just one. Regular ultrasounds and blood tests are done to monitor follicle growth and adjust doses, ensuring good‑quality eggs with minimum risk.
When follicles reach the right size, a trigger injection is given, and egg retrieval is planned 34–36 hours later. Egg retrieval is a short, minimally invasive procedure done under anaesthesia, using a vaginal ultrasound probe and a fine needle to aspirate the follicles.
On the day of egg retrieval, the male partner provides a semen sample, or previously frozen/surgically retrieved sperm are thawed and processed. The andrology lab then prepares the sample to select the most motile and structurally normal sperm for ICSI.
This is the key ICSI step. Under a high‑powered microscope attached to a micromanipulator, an embryologist holds the egg with a holding pipette and injects a single carefully chosen sperm into the egg cytoplasm using a thin injection pipette. The injected eggs are then placed into specialised incubators that maintain an extremely stable environment for fertilisation and early embryo development.
After ICSI, fertilised eggs (zygotes) are carefully monitored for normal division and embryo quality over the next few days. At BabyGen IVF, in almost all cases we follow a freeze‑all strategy, where embryos are grown to day 3 or day 4 (and in selected cases to blastocyst) and then frozen instead of doing a fresh transfer in the same cycle.
Embryos are cryopreserved using modern vitrification techniques that protect them during freezing and storage. This approach allows the woman’s body to recover from stimulation, reduces the effect of high hormone levels on the uterine lining and often gives a calmer, better‑prepared environment for embryo implantation in a later cycle.
Embryo transfer in an ICSI cycle is the same as in IVF – a simple, usually painless procedure where selected embryos are gently placed into the uterus with a thin catheter under ultrasound guidance. You can go home the same day after a brief period of rest.
Hormonal support is given after embryo transfer to help implantation. A blood pregnancy test is done about 12–14 days later, followed by an ultrasound to confirm heartbeat if the test is positive.
IVF success is strongly linked to the woman’s age and egg quality. Younger women typically have higher success, while success gradually declines after the mid‑30s. Your doctor will discuss realistic chances for your age and clinical profile.
Because ICSI bypasses many sperm‑related barriers, the fertilisation rate per egg is often higher in couples with poor semen parameters compared to conventional IVF. ICSI significantly reduces the risk of total fertilisation failure, which can occur in standard IVF, even when sperm counts are borderline.
Even with ICSI, success depends on:
Your doctor will discuss realistic success rates for your specific situation and avoid over‑promising.
In selected cases, techniques like blastocyst transfer, laser assisted hatching, sperm DNA testing or preimplantation genetic testing (PGT) may be suggested. These add‑ons are not for everyone and are recommended only when there is clear benefit.
ICSI is usually priced slightly higher than standard IVF because of the additional micromanipulation work, specialised equipment and embryologist skill involved.
An ICSI package typically includes:
ICSI cost can differ due to dosage of injections, need for additional procedures, lab technology, city, and experience of the team. At BabyGen IVF, you can highlight transparent, written estimates and explain all inclusions and exclusions before treatment to help couples plan with confidence.
Many couples prefer to pay in parts. You can offer EMI or phased payment options, along with transparent, cost‑effective packages that balance affordability with quality.
Differences in lab technology, seniority of doctors, quality of media and consumables, and location costs all influence the package. It is important to compare not just price, but also lab standards, experience and transparency.
The ICSI procedure itself happens in the lab; you don’t feel it. For the woman, discomfort is mainly from injections and the egg retrieval procedure, which is done under anaesthesia so she does not feel pain during the pickup.
No. ICSI is particularly useful for male factor infertility or past fertilisation problems, but it is not automatically needed for every couple. Your fertility specialist will decide whether IVF, ICSI or a combination approach is best based on your reports.
Overall, ICSI is considered safe and widely used worldwide. Some studies show a slightly higher risk of certain problems, but this may be related more to the underlying male factor than to ICSI itself; genetic counselling is suggested in selected cases.
Some couples conceive in the first cycle, while others may require more than one attempt. Age, diagnosis, egg/sperm quality and embryo development all influence how many cycles may be needed to achieve a successful pregnancy.
At BabyGen IVF, ICSI is not just a lab procedure; it is part of a carefully personalised treatment plan designed around your unique fertility challenges.
