What Is In Vitro Fertilization (IVF) Treatment?

In vitro fertilization (IVF) is an assisted reproductive treatment used for couples who cannot conceive naturally. It involves fertilization in a laboratory setting and embryo transfer to the uterus.
This process includes combining eggs retrieved from the woman with the partner’s sperm in the laboratory and transferring the resulting embryo into the uterus.

Today, IVF is one of the most common and successful assisted reproductive methods. With Prof. Dr. Onur Erol’s experience and personalized planning, this journey can be managed in a safer and more successful way.

When Is IVF Treatment Recommended?

IVF treatment may be recommended in the following situations:

  • Blocked or damaged fallopian tubes
  • Advanced endometriosis
  • Diminished ovarian reserve
  • Male factor infertility (low sperm count or poor motility)
  • Failure to achieve pregnancy with other treatments such as IUI
  • Unexplained infertility
  • Desire for pregnancy at advanced maternal age (women over 35)
  • History of recurrent miscarriages

How Is IVF Performed? (Stages)

The IVF process is typically carried out in four main stages. Here is the approach used in Prof. Dr. Onur Erol’s clinic:

1. Ovarian Stimulation

The ovaries are stimulated with a personalized medication protocol. The goal is to develop multiple eggs. This stage usually takes about 8–12 days.

2. Egg Retrieval (OPU)

Once the eggs reach adequate maturity, they are collected under short anesthesia with transvaginal ultrasound guidance. A sperm sample is obtained from the partner on the same day.

3. Fertilization and Embryo Development

Eggs and sperm are fertilized in the laboratory. The embryos are monitored for 3 to 5 days, and the highest-quality embryos are selected.

4. Embryo Transfer

The selected embryo is placed into the uterus. The procedure is painless and does not require anesthesia. A pregnancy test is performed on day 12 after transfer.

Supportive Methods Used in IVF Treatment

  • ICSI (Intracytoplasmic Sperm Injection):
    The direct injection of a single sperm cell into the egg. Commonly used in couples with male factor infertility.
  • PGT-A (Preimplantation Genetic Testing for Aneuploidy):
    Evaluates the chromosomal structure of embryos to support the transfer of genetically healthy embryos.
  • Embryo Freezing:
    If additional high-quality embryos are available, they can be frozen for future use.
  • PRP and Laser-Assisted Implantation Support:
    Helps prepare the uterine environment to support embryo implantation.

IVF Duration and Success Rates

The overall treatment process typically takes about 3–4 weeks.
Success rates vary depending on the woman’s age, ovarian reserve, embryo quality, and other contributing factors.

Average success rates:

  • Under age 30: 55–60%
  • Ages 30–35: ~50%
  • Ages 35–40: 35–45%
  • Over age 40: around 20%

Who May Not Be a Suitable Candidate?

IVF is widely applicable, but in certain situations, additional preparation may be required:

  • Postmenopausal women (except with egg donation)
  • Individuals without a uterus (if a gestational carrier is required)
  • Severe systemic diseases (should be stabilized first)
  • Medical conditions that make pregnancy unsafe

Psychological Support and Process Management

IVF treatment can be an intense process both physically and emotionally.

  • Providing clear information from start to finish
  • Managing expectations realistically
  • Discussing not only success, but also patience and resilience

Prof. Dr. Onur Erol manages this process with one-on-one communication and adopts a reassuring, informative approach at every step.

Nutrition and Lifestyle During IVF Treatment

To increase the chance of success, the following recommendations should be considered:

  • Healthy, balanced nutrition
  • Avoiding smoking and alcohol
  • Maintaining sleep hygiene and stress management
  • Regular light exercise
  • Use of vitamins and supplements (folic acid, vitamin D, etc.) as advised

Frequently Asked Questions

Is IVF treatment painful?
No. Ovarian stimulation is done with injections. Egg retrieval is performed under short anesthesia. Embryo transfer is painless.

What is the chance of success on the first attempt?
Depending on the woman’s age, it ranges between 35% and 60%.

When is embryo freezing performed?
If there are extra high-quality embryos, those not transferred can be frozen. This can be an advantage for a future attempt.

Can I work during the treatment process?
Rest is recommended for a few days in the early phase and after egg retrieval. However, in general, daily life can continue.
