🧬 Overcoming Fertility Challenges with Advanced Sperm Injection Techniques
At Inser Fertility Center, couples facing male infertility, repeated IVF failures, or unexplained fertilization issues can benefit from two of the most advanced micromanipulation techniques in reproductive medicine:
✅ ICSI (Intracytoplasmic Sperm Injection)
✅ ICSI with Morphologically Selected Sperm (IMSI)
Both procedures are designed to maximize fertilization success by directly injecting a selected sperm into a mature egg. Inser’s world-class embryology lab uses cutting-edge tools, high-magnification microscopes, and decades of expertise to offer patients the best possible chance of success.
Accredited by JCI, AAAASF, RedLara, GHA, and ACCERH, Inser is a top choice for local and international patients seeking trusted, results-driven fertility care.
🔍 What Is ICSI (Intracytoplasmic Sperm Injection)?
ICSI is a highly advanced micromanipulation technique in which a single sperm is carefully injected into the cytoplasm of a mature egg. This technique allows fertilization even in cases where the sperm would otherwise be unable to penetrate the egg naturally.
At Inser, this procedure is performed by expert embryologists using state-of-the-art equipment to ensure precision, safety, and the highest chances of successful fertilization.


ICSI is typically recommended when:
- There is low sperm count (oligospermia)
- Sperm has poor motility (asthenozoospermia) or abnormal morphology (teratozoospermia)
- Sperm retrieval is required via TESA/PESA/TESE due to vasectomy or azoospermia
- Prior IVF cycles have failed due to poor fertilization
- Eggs need to be fertilized with frozen sperm or donor sperm
- Preimplantation genetic testing is being performed
- Antisperm antibodies are present, affecting the sperm’s ability to bind with the egg
- Conventional IVF has resulted in low fertilization rates despite normal sperm parameters.
- A limited number of mature eggs are available, and maximizing fertilization is critical.
🔍 What Is IMSI (ICSI with Morphologically Selected Sperm (IMSI)?
ICSI with Morphologically Selected Sperm (IMSI) is a more advanced version of ICSI. It involves selecting sperm under ultra-high magnification (up to 6000x) to assess the morphology (shape and structure) in far greater detail than conventional ICSI.
This enhanced selection process allows embryologists to identify and exclude sperm with even subtle abnormalities that may not be visible under standard magnification
By eliminating sperm with head vacuoles or visible defects, IMSI improves the chances of choosing genetically healthy sperm. This can lead to better embryo quality, higher implantation rates, and lower miscarriage risks.


✅ IMSI Is Recommended When:
- Previous IVF or ICSI cycles failed
- Embryo quality or development was poor
- There’s a high percentage of abnormally shaped sperm
- High DNA fragmentation is a concern
- Male partner has oxidative stress or prior exposure to chemotherapy/radiation
- The couple is undergoing PGT-A/PGT-M and needs optimal sperm quality
- The couple is seeking to maximize embryo quality before a single embryo transfer (SET)
- There is a history of early miscarriage suspected to be related to male factor infertility

⚙️ How ICSI and IMSI Work at Inser
1. Initial Evaluation
Fertility testing for both partners to determine whether ICSI or IMSI is the best fit.
2. Ovarian Stimulation and Egg Retrieval
The female partner receives medication to stimulate egg production. Eggs are collected through a minimally invasive procedure.
3. Sperm Collection and Preparation
Sperm is collected via ejaculation or surgical retrieval, then prepared for microinjection.
4. Micromanipulation
- In ICSI, sperm is selected and injected under standard high-resolution microscopy.
- In IMSI, sperm is chosen using ultra-high magnification for enhanced quality control.
5. Embryo Culture and Transfer
Fertilized eggs are monitored in the lab. The healthiest embryos are transferred into the uterus or frozen for future use.
