What is IVF?
💡 IVF = eggs retrieved from ovaries, fertilised in lab, embryo transferred to uterus. A full cycle takes 10–14 days of injections + egg retrieval + 5-day embryo culture + transfer. Success rate per transfer (India): 40–55% (age <35), declining with age. Key steps: ovarian stimulation → egg retrieval → fertilisation → embryo culture → embryo transfer.
IVF (in vitro fertilisation) is the most effective assisted reproductive technology, in which eggs are retrieved from the ovaries, fertilised with sperm in a laboratory, and the resulting embryo is transferred to the uterus. IVF is indicated for tubal factor infertility, severe male factor, endometriosis, unexplained infertility after simpler treatments have failed, and poor ovarian reserve requiring maximised egg collection.
🇮🇳 India Context: IVF is widely assessed and treated across major Indian fertility centres including Chennai, Mumbai, Bangalore, Delhi, and Hyderabad.
What are the key characteristics of IVF?
- Ovarian stimulation: daily gonadotropin injections (FSH ± LH) for 8–12 days; dose personalised to AFC and AMH; monitored by serial TVS + E2 blood tests
- Trigger shot: hCG or GnRH agonist given when ≥2 follicles reach ≥18mm; triggers final egg maturation; retrieval scheduled 35–36 hours later
- Egg retrieval: transvaginal ultrasound-guided needle aspiration under sedation/GA; 15–30 minutes; day procedure
- Fertilisation: conventional IVF (sperm added to eggs in dish) or ICSI (single sperm injected into each egg); fertilisation confirmed at 17–19 hours
- Embryo culture: fertilised eggs cultured 3–5 days; Day 5 blastocyst stage preferred — higher implantation rate; graded by ICM and trophectoderm quality
- Embryo transfer: 1–2 embryos placed in uterus via soft catheter under abdominal USS guidance; painless; no anaesthesia; 15 minutes
- Luteal support: progesterone pessaries/injections started day of retrieval; continued for 10–12 weeks if pregnant
- Beta-hCG test: 14 days post-retrieval; positive = pregnant; clinical pregnancy confirmed by TVS at 6–7 weeks

Why does IVF matter in fertility?
IVF is the definitive fertility treatment — the intervention with the highest per-cycle success rate of all ART. The single most important outcome predictor is age: under 35, live birth rates per transfer are 40–55%; by 40, this drops to 15–25%; by 43+, own-egg IVF success is <5% per cycle and donor egg IVF is recommended. The most impactful quality decision a patient makes is embryo culture to Day 5 blastocyst (vs Day 3 cleavage transfer) — blastocyst transfer selects the most viable embryo and significantly improves implantation rates per transfer.

FAQs about IVF
What is the success rate of IVF in India?
IVF success rates in India range from 35–55% per cycle for women under 35, decreasing with age. Top-tier clinics in Chennai, Mumbai, and Bangalore report rates comparable to international standards. Success depends on age, cause of infertility, embryo quality, and clinic expertise.
How much does one IVF cycle cost in India?
A single IVF cycle costs ₹1,00,000 to ₹3,00,000 in India, depending on the city, clinic, and whether additional procedures like ICSI, PGT, or embryo freezing are needed. Medications add ₹20,000–₹80,000.
How many IVF cycles are typically needed to get pregnant?
Many couples conceive within 1–3 IVF cycles. Cumulative success rates across 3 cycles reach 60–70% for women under 38. Your doctor will recommend the optimal approach based on your response to each cycle.
Is the IVF process painful?
Most steps involve mild discomfort rather than significant pain. Daily injections use fine needles. Egg retrieval is done under sedation. Embryo transfer is similar to a Pap smear. The emotional stress is often more challenging than physical discomfort.
What is the difference between IVF and IUI?
IUI places washed sperm directly into the uterus, while IVF involves retrieving eggs, fertilising them in a lab, and transferring embryos. IVF has higher success rates (35–55% vs 10–20%) but is more invasive and expensive.
At what age is IVF most successful?
IVF is most successful for women under 35 (40–55% per cycle). Success declines after 35 and more significantly after 40. Women over 42 may be advised to consider donor eggs for better outcomes.
How long does one IVF cycle take?
One IVF cycle takes 4–6 weeks of active treatment. Including pre-cycle testing and consultation, the total journey from first appointment to pregnancy test is typically 3–4 months.
