When couples face infertility challenges, assisted reproductive techniques like IVF Treatment and ICSI offer hope. While both procedures aim to achieve fertilization, ICSI (Intracytoplasmic Sperm Injection) is often recommended in specific cases.
Let’s explore the key differences between the two treatments and who qualifies for ICSI.
What Is the Difference Between IVF and ICSI?
- In IVF, eggs and many sperm are placed together in a dish, allowing fertilization to happen naturally.
- In ICSI, a single sperm is directly injected into each egg using a fine needle under a microscope.
While IVF mimics natural fertilization, ICSI bypasses many sperm-related barriers and is more controlled.
Who Is Eligible for ICSI Over IVF?
ICSI is typically recommended in the following situations:
1. Male Infertility Issues
ICSI is the preferred option for couples facing male factor infertility, such as:
- Low sperm count (oligospermia)
- Poor sperm motility (asthenozoospermia)
- Abnormal sperm shape (teratozoospermia)
- Blockages preventing sperm ejaculation (like in vasectomy or retrograde ejaculation)
2. Azoospermia with Sperm Retrieval
In cases where no sperm is found in semen (azoospermia), sperm can be surgically retrieved using methods like TESA, PESA, or micro-TESE. These retrieved sperm are limited and can’t swim, so ICSI is essential for fertilization.
3. Previous IVF Failure
If a couple has undergone IVF and experienced failed or poor fertilization, ICSI may be advised in the next cycle to increase fertilization chances.
4. Low Egg Count or Poor Egg Quality
When a woman produces only a few eggs during stimulation, doctors may recommend ICSI to maximize fertilization rates with each egg.
5. Preimplantation Genetic Testing (PGT)
Couples opting for PGT may undergo ICSI to prevent contamination from multiple sperm, ensuring accurate genetic analysis.
Final Thoughts
ICSI is a powerful technique that has transformed outcomes for couples facing complex fertility issues especially those related to male infertility. However, not every case needs ICSI. For couples with normal sperm parameters and no history of fertilization failure, conventional IVF may be sufficient.
Your fertility specialist will carefully assess both partners’ medical history, test results, and previous treatment outcomes before recommending ICSI over IVF. Personalized care is key to achieving the best results in your fertility journey.
