IVF treatment (In Vitro Fertilization) is one of the most effective ways for many couples to have children today. However, every treatment is personalized, and the success rate depends on many different factors. Scientific studies show that many elements, from the preparation process of both the prospective mother and father to the laboratory conditions, directly affect the treatment outcome. In this article, we discuss 5 important scientific factors that increase success in IVF.

Female Age and Ovarian Reserve

Female age is one of the most decisive factors in IVF success. Since egg quality is higher in women under 35, the success rate also increases. However, this difference can be reduced with personalized protocols at older ages. The Anti-Müllerian Hormone (AMH) test provides important information about ovarian reserve.

Embryo Quality

Embryo development is affected by the combination of genetics and laboratory conditions. Monitoring embryos with advanced microscope technologies (like the Time-Lapse system) ensures the selection of the highest quality embryo and increases the chance of pregnancy.

Uterine (Endometrium) Health

For the embryo to implant in the uterus, the endometrium layer must reach a certain thickness. Hormonal balances, intrauterine polyps, or myomas can affect this process. Ultrasound and hysteroscopy evaluation before embryo transfer increases the implantation rate.

Sperm Quality

The male factor accounts for nearly 40% of IVF success. As much as sperm count, motility, and morphology, DNA integrity is also important. Especially in older men, the DNA fragmentation test plays a decisive role in treatment planning.

Clinical Experience and Laboratory Technology

The experience of the team managing the treatment and the equipment of the laboratory are among the most critical success factors in IVF. The expertise of embryologists, the quality of incubators, and the stability of culture media directly affect the success rate.

IVF treatment is not just a medical process; it also requires patience, trust, and a scientific approach. The path to success involves taking the right steps at the right time.

Frequently Asked Questions

Is there an age limit for IVF?

Generally, attempts can be made up to age 45, but the success rate drops significantly after age 40.

Does stress affect IVF success?

Yes, stress hormones indirectly affect the reproductive system. Therefore, psychological support is an important part of the process.

How many times can IVF be attempted?

As long as there is no medical obstacle, multiple attempts are possible; an evaluation is generally made after 3 attempts.

Does the embryo freezing process reduce success?

No, thanks to modern freezing methods (vitrification), success rates are equivalent to fresh transfers.

Is nutrition important before IVF?

Absolutely yes. A diet rich in protein, antioxidants, and folic acid supports egg quality.
