ICSI — Intracytoplasmic Sperm Injection — has transformed the treatment of male infertility and revolutionised IVF outcomes worldwide since its introduction in 1992. Today, ICSI is performed in the majority of IVF cycles globally, and at Mother Hospitals & IVF Center in Boduppal, Hyderabad, it is a routine part of our advanced fertility programme.
If you or your partner have been told you need ICSI, this guide will help you understand exactly what it involves, why it is recommended, and what you can expect during treatment with Dr. E. Prashanthi Reddy and our team.
Key Fact: ICSI achieves fertilisation rates of 70–80% per mature egg, even with very low sperm counts. It has made pregnancy possible for millions of couples who previously had no other options.
What Is ICSI? Understanding the Procedure
In conventional IVF, a large number of sperm are placed in a dish with eggs, and fertilisation occurs naturally when a sperm successfully penetrates and fertilises an egg. This requires sperm to be present in adequate numbers and to have sufficient motility and morphology to complete fertilisation unaided.
ICSI bypasses this natural selection process entirely. Using a highly specialised micromanipulation system and a glass needle (micropipette) thinner than a human hair, the embryologist selects a single healthy-looking sperm and injects it directly into the cytoplasm of each mature egg. The result is the same — a fertilised egg (zygote) that can develop into an embryo — but ICSI can achieve this even with very few, poorly motile, or surgically retrieved sperm.
When Is ICSI Recommended?
Dr. Prashanthi Reddy recommends ICSI in the following situations:
Male Factor Infertility
- Oligospermia: Low sperm count (below 5–10 million/mL total motile sperm)
- Severe asthenospermia: Very poor sperm motility
- Teratospermia: Mostly abnormally shaped sperm
- Azoospermia: No sperm in the ejaculate — sperm retrieved via TESA/PESA are used with ICSI
- High DNA fragmentation: Significant DNA damage in sperm affecting fertilisation
Previous IVF Failure
- Low or failed fertilisation in a previous conventional IVF cycle
- Recurrent IVF failure where fertilisation rate was suboptimal
Frozen or Surgically Retrieved Sperm
Sperm that has been previously frozen (cryopreserved) or surgically retrieved from the testis or epididymis (TESA/PESA) is almost always used with ICSI, as the numbers and motility available may be limited.
Very Few Eggs Retrieved
When only a small number of mature eggs are retrieved (particularly common in women with low ovarian reserve or low AMH), ICSI ensures maximum fertilisation efficiency rather than leaving fertilisation to chance.
The ICSI Procedure — Step by Step
The ICSI procedure is part of an overall IVF cycle. Here is the complete process at Mother Hospitals:
Step 1: Ovarian Stimulation (Days 1–12)
The female partner receives daily hormone injections (FSH, with or without LH) to stimulate the ovaries to produce multiple follicles containing eggs. Regular monitoring with ultrasound and blood tests tracks follicle development. At Mother Hospitals, our Needleless IVF protocol uses an oral medication approach to stimulation for patients who wish to avoid daily injections.
Step 2: Trigger Shot and Egg Retrieval (OPU)
When follicles reach the right size (18–20 mm), a trigger injection (hCG or GnRH agonist) is given to mature the eggs. Approximately 36 hours later, eggs are retrieved under sedation using a thin ultrasound-guided needle passed through the vaginal wall into each follicle.
Step 3: Sperm Collection
On the day of egg retrieval, the male partner provides a semen sample. If azoospermia is present or sperm are being used from a previous freeze, TESA or PESA may be performed on the same day.
Step 4: ICSI Fertilisation
In our embryology laboratory, mature eggs (MII oocytes) are identified. The embryologist then uses a micromanipulation system to inject a single selected sperm into each mature egg. This process takes 1–2 hours and is performed the same day as egg retrieval. Each egg is assessed for normal fertilisation the following morning (the presence of two pronuclei confirms successful fertilisation).
Step 5: Embryo Culture (Days 1–5)
Fertilised eggs are cultured in the incubator for 3–5 days. On day 5, the embryos are assessed for blastocyst development. Blastocyst-stage embryos have the highest implantation potential. Grading is based on cell number, symmetry, fragmentation, and inner cell mass quality.
Step 6: Embryo Transfer
One or two of the best-quality embryos are selected and transferred into the uterus through a thin catheter — a painless procedure similar to a Pap smear. Remaining embryos of good quality can be frozen (vitrification) for future transfers.

| Feature | Conventional IVF | ICSI |
|---|---|---|
| Fertilisation method | Natural — sperm swim to egg | Single sperm injected into egg |
| Sperm required | Millions of motile sperm | As few as a single sperm |
| Used for | Normal sperm parameters | Male factor, low egg numbers, failed IVF |
| Fertilisation rate | 60–70% | 70–80% |
| Additional cost | Base IVF cost | Marginally higher (lab skill intensive) |
| Embryo quality | Comparable | Comparable |
| Pregnancy rates | Similar to ICSI | Similar to IVF |
It is worth noting that in many clinics, ICSI has become the default for nearly all IVF cycles due to its higher and more predictable fertilisation rate. At Mother Hospitals, we discuss with each couple whether conventional insemination, ICSI, or a split (some eggs conventionally inseminated, some ICSI) is the best approach for their specific situation.
ICSI Success Rates in Hyderabad
ICSI fertilisation rates are typically 70–80% per mature egg injected. However, success ultimately depends on:
- The age of the female partner (egg quality is the single biggest factor)
- The number and quality of eggs retrieved
- Underlying cause of infertility
- Embryo quality after culture
- Uterine receptivity at the time of transfer
At Mother Hospitals, our overall pregnancy rates per embryo transfer are benchmarked against ICMR national standards. You can review our IVF success rate guide for more context on age-specific outcomes.
ICSI Cost in Hyderabad — 2026
At Mother Hospitals & IVF Center, the ICSI procedure is included within our all-inclusive IVF package of ₹99,000 (valid till 30 June 2026). This package covers:
- All pre-cycle consultation and investigations
- Ovarian stimulation injections
- Monitoring ultrasounds and blood tests
- Egg retrieval (OPU) under sedation
- ICSI fertilisation in the embryology laboratory
- Embryo culture up to blastocyst stage

There are no hidden charges. For a detailed cost breakdown, see our IVF cost guide.
Remember: ICSI is not just for severe male infertility. If you have had a failed IVF cycle with poor fertilisation, or if very few eggs were retrieved, switching to ICSI in the next cycle can significantly improve your fertilisation rate.

What is ICSI and how is it different from IVF?
In conventional IVF, eggs and sperm are placed together in a dish and fertilisation occurs naturally. In ICSI, a single sperm is selected and injected directly into each mature egg by an embryologist using a microscopic needle. ICSI is used when sperm quality is poor or when previous IVF cycles had low fertilisation rates.
Who needs ICSI instead of conventional IVF?
ICSI is recommended for men with low sperm count, poor motility or abnormal morphology, azoospermia (requiring TESA/PESA), previous low fertilisation with standard IVF, frozen sperm being used, or where the female partner has very few eggs retrieved.
What is the ICSI success rate in Hyderabad?
ICSI fertilisation rates are typically 70–80% per mature egg injected. Pregnancy rates per transfer depend on embryo quality and maternal age, ranging from 40–65% for women under 35. At Mother Hospitals, our ICSI outcomes are benchmarked against national ICMR standards.
What is the cost of ICSI treatment in Hyderabad?
The ICSI procedure cost at Mother Hospitals is included within our ₹99,000 all-inclusive IVF package (valid till 30 June 2026). This covers stimulation injections, egg retrieval, ICSI fertilisation, embryo culture, embryo transfer, and all monitoring scans. No hidden charges.
Is ICSI safe? Are there any risks?
ICSI is considered safe. The risk of birth defects is slightly elevated compared to natural conception (similar to standard IVF), which may reflect the underlying infertility rather than the procedure itself. Multiple pregnancy risk is managed by transferring one or two embryos. The procedure itself carries no significant risk to the eggs.
