What Is IVF and How Does It Work?

Medically reviewed on 13 July 2026 - Dr. Senai Aksoy

IVF (in vitro fertilisation) means eggs and sperm meet in the laboratory, then one or more embryos are transferred to the uterus. ICSI is a related fertilisation method that injects a single sperm into each egg.

Dr. Senai Aksoy explains the steps in the medical animation below. The written guide that follows covers the same pathway for readers who prefer text — including how IVF treatment in Turkey is organised for international patients.


The six steps of IVF treatment

StepWhat happens
1. Consultation & planningRecords, diagnosis, and whether IVF or ICSI fits
2. Ovarian stimulationMedication grows several follicles; monitoring by ultrasound and blood tests
3. Egg retrievalEggs collected with a fine needle under light sedation
4. FertilisationConventional IVF or intracytoplasmic sperm injection (ICSI)
5. Embryo transferOne or two selected embryos placed in the uterus
6. Pregnancy testBlood beta-hCG, then ultrasound follow-up if positive

Ovarian reserve (AMH, antral follicle count, age) helps estimate how the ovaries may respond to stimulation. It does not guarantee egg quality or pregnancy. Sperm parameters, uterine findings, and previous cycle history also shape the plan.

IVF versus ICSI

IVF places eggs and prepared sperm together so fertilisation can occur in the dish.

ICSI injects a single sperm into each mature egg. It is often used for male-factor infertility, prior fertilisation failure, or when the team judges microinjection more reliable for that case.

Both pathways still require ovarian stimulation, egg retrieval, embryo culture, and transfer (or freeze-all). The difference is mainly how fertilisation is achieved in the lab.

IVF in Turkey for international patients

IVF treatment in Turkey is available to eligible married heterosexual couples using their own gametes, under Turkish Ministry of Health rules.

International patients often compare clinics in Turkey when they want specialist care coordinated in English, French, or Arabic, with a travel plan built around the cycle. Turkey is one destination among several — not a “best country” label.

Cost of IVF treatment — how to read an estimate

People search IVF prices and IVF costs in Turkey for a reason: budgets matter. A responsible estimate lists what is included and what is not — stimulation drugs, freezing and storage, genetic testing, surgical sperm retrieval, and return travel for a frozen transfer.

This page does not publish a sales package. For the clinic’s estimate structure and informational ranges, see IVF / ICSI treatment pricing.

After transfer: the pregnancy test

About 9–14 days after transfer, a blood pregnancy test measures beta-hCG. One positive number is encouraging; serial values and ultrasound complete the picture. See beta-hCG after IVF.

Safety and regulation

All IVF procedures described here are performed in Istanbul in accordance with Turkish Ministry of Health regulations for assisted reproductive treatment. This content is educational and does not replace individual medical consultation.

Patients comparing clinics should ask about licensing, laboratory witnessing, OHSS prevention, embryo-transfer limits, and after-hours contact — the same checklist used in our IVF in Turkey guide.

Dr. Senai Aksoy studied and trained in France before returning to Turkey, where he was a founding member of the ICSI team at Sevgi Hospital, Ankara — the country's first ICSI centre (1994-95) — and a co-author on the first Turkish ICSI publications produced in collaboration with the Brussels Van Steirteghem group (Human Reproduction, 1996; PMID 8671323). He helped build the IVF programme at the American Hospital Istanbul and has been running his own fertility practice since 1998.
