For many couples trying to conceive, male infertility can be a silent but significant roadblock. In recent years, assisted reproductive technologies like IVF in Ahmedabad have made incredible strides—offering new hope to those struggling with infertility. IMSI (Intracytoplasmic Morphologically Selected Sperm Injection), an improvement on ICSI (Intracytoplasmic Sperm Injection), is one such invention.
If you or your partner have been diagnosed with male infertility or have had unsuccessful IVF/ICSI cycles, IMSI may offer an improved path toward parenthood. This complete guide from Sneh IVF, a top IVF center in Ahmedabad, will help you understand what IMSI is, how it works, who it helps, and what to expect from the treatment.
What Is IMSI?
IMSI (Intracytoplasmic Morphologically Selected Sperm Injection) is an enhanced ICSI technique. The key difference? Sperm are selected under extremely high magnification—up to 6000 times—to identify even the most subtle abnormalities.
To put it another way, IMSI assists embryologists in selecting the sperm that have the greatest structure and the healthiest appearance, increasing the chances of successful fertilization and embryo development.
It’s particularly useful when there’s a high level of abnormal sperm morphology (shape/structure) or when previous IVF in Ahmedabad or ICSI cycles have failed for unclear reasons.
IMSI vs ICSI: What’s the Difference?
To further understand IMSI, it is useful to first grasp ICSI:
- ICSI involves injecting a single sperm directly into an egg using a microscope magnified around 200–400 times.
- High-magnification microscopes (up to 6000x) are used by IMSI to examine the interior structure of sperm, especially the nucleus, which houses the DNA.
Who Should Consider IMSI?
IMSI is not required for every fertility case, but it’s especially recommended when:
- The male partner has a high percentage of abnormally shaped sperm (teratozoospermia).
- There have been repeated IVF or ICSI failures without clear explanation.
- There’s a history of miscarriage or poor embryo development.The fragmentation of sperm DNA is either suspected or confirmed.
- Sperm retrieved surgically (via TESA/TESE) show poor morphology.
- The couple wants to maximize their chance of success using the best sperm selection method available.
The IMSI Procedure at Gujarat's Top IVF Facility, Sneh IVF
The IMSI procedure follows the same structure as a typical IVF in Ahmedabad cycle, with the main difference being the sperm selection stage.
1. Initial Assessment and Consultation
The process begins with a full fertility evaluation of both partners, including:
Examining semen to ascertain the morphology, count, and motility of sperm
Hormonal tests
Pelvic ultrasound for the female partner
Discussion of previous IVF center in Ahmedabad attempts and any fertility concerns
If male infertility is diagnosed or suspected, your doctor at Sneh IVF, regarded as the best IVF doctor in Ahmedabad, may recommend IMSI.
2. Ovarian Stimulation (Female Partner)
The female partner gets hormone injections to stimulate the ovaries and produce multiple eggs, just like in IVF or ICSI.
3. Egg Retrieval
Approximately 34–36 hours after the trigger shot, a minor procedure called Ovum Pick-Up (OPU) is done.
4. High-Magnification Sperm Selection (IMSI Step)
The sperm sample is placed under a high-powered microscope (6000x magnification). Embryologists at Sneh IVF, one of the top IVF centers in Ahmedabad, assess each sperm’s shape, head structure, and presence of vacuoles—only the most normal-looking sperm are chosen.
5. Fertilization via Microinjection
Each ripe egg is carefully implanted with a single sperm.
6. Embryo Development
After being cultivated for three to five days in the lab, the embryos are chosen according to their quality.
7. Embryo Transfer
A simple outpatient procedure transfers one or more viable embryos into the uterus.
8. The Two-Week Wait
A pregnancy test is performed 12–14 days later.
IMSI Success Rates
While IMSI is newer than ICSI, studies show improved fertilization and embryo quality in cases of poor sperm morphology—especially when done at a reputable Best IVF center in Ahmedabad like Sneh IVF.
Success rates vary based on:
- The woman’s age
- Embryo quality
- Overall fertility factors
- Lifestyle and health
