IVF Step by Step

Prof. Dr. İkbal KaygusuzLast reviewed: 25 September 2026
In short: IVF consists of an initial assessment, ovarian stimulation lasting about 8-12 days, egg collection, fertilisation in the laboratory, 3-5 days of embryo development and embryo transfer. The pregnancy test is done about 9-12 days after transfer. The whole process usually takes 4-6 weeks.

1. Initial assessment

Before treatment, ovarian reserve (AMH and antral follicle count), the uterus and tubes, hormone levels and the partner's semen analysis are assessed. Infection screening, genetic tests or hysteroscopy may be planned if needed. This assessment determines the medication protocol.

2. Ovarian stimulation

Injections starting on day 2-3 of the cycle help several follicles develop. This phase usually lasts 8-12 days, and follicle growth is monitored with ultrasound and blood tests so that doses can be adjusted.

3. Trigger injection

When the follicles are large enough, a trigger injection completes egg maturation. Egg collection is planned about 34-36 hours later, so the injection time must be followed exactly.

4. Egg collection

The procedure is done under brief sedation with vaginal ultrasound guidance and usually takes 15-20 minutes. A semen sample is provided on the same day, and you can go home after a few hours of rest.

5. Laboratory stage

Eggs are fertilised by conventional IVF or by injecting a single sperm into each egg (ICSI). Embryos are monitored in the laboratory for 3 to 5 days, and preimplantation genetic testing (PGT) may be performed when indicated.

6. Embryo transfer

The selected embryo is placed in the uterus with a thin catheter. The procedure usually causes little discomfort and needs no anaesthesia. The number of embryos transferred depends on age and embryo quality within the legal framework, and good-quality embryos can be frozen.

7. After transfer

Progesterone is used to support the uterine lining. A blood pregnancy test (beta-hCG) is done about 9-12 days after transfer. You can continue daily life, avoiding strenuous exercise.

IVF procedures (egg collection and embryo transfer) are performed at a licensed IVF center. Assessment, planning and follow-up take place at the clinic.

Frequently Asked Questions

Can I work during IVF treatment?
Most women continue working during stimulation. Rest is advised on the day of egg collection and the following day.
Is egg collection painful?
It is done under sedation, so you will not feel pain during the procedure. Mild cramping afterwards usually settles with simple painkillers.
Do I need bed rest after transfer?
No. Current evidence shows that bed rest does not improve pregnancy chances; you can return to daily life.
