Couples considering fertility treatment often ask, “How long does the IVF process take?” While IVF is not an instant solution, it follows a structured medical timeline designed to maximise success. On average, the IVF journey from the first consultation to pregnancy confirmation takes about 6 to 8 weeks, though this can vary based on individual factors and treatment plans.
Step 1: Initial Consultation and Fertility Evaluation (1–2 Weeks)
The IVF journey begins with a detailed fertility assessment for both partners. This includes:
- Hormone blood tests
- Ultrasound scans
- Semen analysis
- Review of medical and reproductive history
These tests help fertility specialists design a customised IVF protocol. At a reputed and experienced IVF clinic, this phase is usually completed efficiently within 1 to 2 weeks.
Step 2: Ovarian Stimulation (10–14 Days)
In this phase, hormonal injections stimulate the ovaries to produce multiple eggs. During ovarian stimulation:
- Regular ultrasounds monitor follicle growth
- Blood tests track hormone levels
- Medication doses may be adjusted
This step typically lasts 10 to 14 days and is crucial for IVF success.
Step 3: Egg Retrieval and Fertilisation (1 Day)
Once the eggs mature, they are retrieved through a short, minimally invasive procedure. On the same day:
- A semen sample is collected
- Fertilisation occurs in the lab using IVF or ICSI
The procedure is usually painless, and patients return home the same day.
Step 4: Embryo Development (3–5 Days)
Fertilised eggs are monitored in the lab as they develop into embryos. This stage lasts:
- 3 days (cleavage stage) or
- 5 days (blastocyst stage)
Advanced labs at the best IVF centre in Delhi use strict quality control to select the healthiest embryos.
Step 5: Embryo Transfer (Day 3 or Day 5)
Embryo transfer is a simple, painless outpatient procedure that takes only a few minutes. After transfer:
- Hormonal support continues
- Most women can resume normal daily activities with care
Step 6: Pregnancy Test – The Two-Week Wait (12–14 Days)
About 12 to 14 days after embryo transfer, a blood test (beta-hCG) confirms pregnancy. This waiting period can be emotionally challenging, and clinics often provide counselling and support during this time.
Total IVF Timeline briefly
| Stage | Duration |
| Consultation & tests | 1–2 weeks |
| Ovarian stimulation | 10–14 days |
| Egg retrieval & embryo development | 4–6 days |
| Pregnancy confirmation | 2 weeks |
| Total IVF duration | 6–8 weeks |
Can the IVF Process Take Longer?
Yes. IVF may take longer in cases where:
- Embryos are frozen for later transfer
- Genetic testing (PGT) is required
- The body needs recovery time before embryo transfer
- Multiple IVF cycles are needed
A trusted fertility specialist will guide you on the safest and most effective timeline.
Although IVF takes several weeks, it is a carefully planned process focused on achieving a healthy pregnancy. Consulting with IVF specialists ensures expert medical guidance, advanced technology, and emotional support throughout the journey.
