Intracytoplasmic Sperm Injection: Process, Costs, Success Rates & Expert Insights for Delhi NCR
Understanding Intracytoplasmic Sperm Injection (ICSI)
The revolutionary fertility treatment that has transformed male infertility treatment since 1992
What is ICSI Exactly?
Intracytoplasmic Sperm Injection (ICSI) is an advanced assisted reproductive technology (ART) that involves directly injecting a single, healthy sperm into a mature egg. Unlike conventional IVF where sperm and eggs are mixed together, ICSI bypasses natural fertilization barriers.
The revolutionary process involves:
- Micromanipulation: High-precision injection under microscope
- Single Sperm Selection: Choosing the best sperm for injection
- Direct Injection: Placing sperm directly into egg cytoplasm
- Bypassing Barriers: Overcoming sperm motility or penetration issues
When is ICSI Needed? 8 Key Medical Indications
Ideal Candidates Include:
- Severe Male Factor Infertility: Low sperm count (<5 million/mL)
- Poor Sperm Motility: Less than 30% progressive movement
- Abnormal Sperm Morphology: Less than 4% normal forms
- Previous IVF Failure: Poor fertilization in prior cycles
- Surgical Sperm Retrieval: TESA, PESA, Micro-TESE cases
- Frozen Sperm Samples: Limited quantity or quality
- PGT Requirements: Avoiding DNA contamination for genetic testing
- Unexplained Infertility: After failed conventional treatments
Understanding ICSI Terminology
Micromanipulation
Precise handling of sperm and eggs under high magnification
Intracytoplasmic
"Inside the cytoplasm" - sperm injected directly into egg
PGT-Compatible
ICSI prevents sperm DNA contamination for genetic testing
The Step-by-Step ICSI Process
Precision micromanipulation for overcoming male infertility (6-8 weeks total)
Ovarian Stimulation
Time: Days 1-12 (10-14 days)
Hormonal injections stimulate ovaries to produce multiple mature eggs. Regular monitoring tracks follicle growth and egg development.
Egg Retrieval & Preparation
Time: Day 13-14
Eggs retrieved via transvaginal ultrasound. Cumulus cells removed to assess maturity. Only mature eggs (MII) proceed to ICSI.
Sperm Preparation
Time: Day 14
Sperm sample washed and prepared. For severe cases, surgical retrieval (TESA/PESA) performed. Sperm assessed for motility and morphology.
Sperm Selection & Immobilization
Time: Day 14
Single healthy sperm selected under 400-6000x magnification. Tail gently snapped to immobilize sperm before injection.
Micromanipulation & Injection
Time: Day 14 (2-3 hours)
Egg stabilized with holding pipette. Injection needle inserts sperm through zona pellucida into cytoplasm. Sperm deposition confirmed.
Embryo Culture & Transfer
Time: Days 15-20
Injected eggs cultured 3-5 days in incubator. Embryo development monitored. Best embryo(s) transferred to uterus on day 3 or 5.

Top 10 FAQs on ICSI Treatment
Everything you need to know about Intracytoplasmic Sperm Injection
Answer: ICSI (Intracytoplasmic Sperm Injection) is an advanced ART technique where a single sperm is directly injected into a mature egg using microscopic tools. Unlike conventional IVF where sperm and eggs are mixed together, ICSI actively bypasses natural fertilization barriers.
Key differences:
- Method: ICSI uses micromanipulation; IVF uses natural fertilization
- Sperm requirement: ICSI needs only one sperm per egg; IVF needs thousands
- Fertilization rate: ICSI achieves 70-85% vs. IVF's 50-60%
- Cost: ICSI adds ₹25,000-₹70,000 to standard IVF cost
- Indications: ICSI for severe male factor; IVF for other infertility causes
Answer: Extensive 30+ years of research shows ICSI babies have similar overall health outcomes as naturally conceived or IVF babies. The birth defect risk is 2-3%, comparable to general population rates.
Safety considerations:
- Long-term studies: Show normal physical and neurodevelopmental outcomes
- Genetic risks: Slight increase in sex chromosome abnormalities (0.8% vs 0.2%) linked to underlying male infertility, not ICSI procedure
- Imprinting disorders: Extremely rare, not conclusively linked to ICSI
- Multiple pregnancies: Risk depends on number of embryos transferred, not ICSI itself
Answer: ICSI success varies by multiple factors but generally achieves:
Fertilization rates: 70-85% of mature eggs successfully fertilized
Live birth rates by age:
- Under 35: 50-65% per cycle
- 35-37: 40-55% per cycle
- 38-40: 30-45% per cycle
- Over 40: 15-25% with own eggs, 50-70% with donor eggs
Cumulative success rates after multiple cycles:
- After 3 ICSI cycles: 75-85% for women under 35
- After 3 ICSI cycles: 65-75% for women 35-40
Answer: Embryologists use multiple criteria to select the best sperm:
- Morphology: Normal head, midpiece, and tail structure
- Motility: Progressive, forward movement
- Viability: Confirming sperm is alive and healthy
- Maturity: Selecting sperm that have completed maturation
Advanced selection techniques (2026):
- PICSI: Selects sperm that bind to hyaluronic acid (indicates maturity)

Answer: While ICSI is generally safe, consider these aspects:
Medical considerations:
- Cost: Significant additional expense over standard IVF
- Egg damage risk: 1-3% of eggs may be damaged during injection
- Genetic transmission: May transmit genetic causes of male infertility to male offspring
- Multiple pregnancies: Risk if multiple embryos transferred (clinic-controlled)
Ethical/psychological considerations:
- Overuse: Some clinics may recommend ICSI when not medically necessary
- Genetic selection: Advanced sperm selection raises ethical questions
- Psychological pressure: High expectations due to advanced technology
- Financial burden: Additional costs may limit accessibility
Answer: Yes, ICSI works well with frozen gametes:
Frozen sperm with ICSI:
- Success rates: Similar to fresh sperm when properly frozen/thawed
- Indications: Cancer patients pre-treatment, military personnel, travel constraints
- Considerations: Post-thaw motility may be reduced, making ICSI advantageous
- Cryopreservation methods: Slow freezing or vitrification with cryoprotectants
Frozen eggs with ICSI:
- Success rates: 85-95% survival with vitrification, similar fertilization to fresh
- Indications: Fertility preservation, egg donation programs, scheduling flexibility
- 2026 advancements: Vitrification techniques achieve near-identical outcomes to fresh eggs
- Legal aspects: Well-established protocols, widely accepted in India
