The Importance of the PICSI Method in Male Infertility

Male infertility, encountered as a significant reproductive health issue in couples experiencing difficulty conceiving, can arise due to disorders in sperm count, motility, and structural characteristics. Particularly in cases where sperm quality negatively affects the fertilization process, advanced sperm selection methods used in IVF treatment come into play. One of these methods, PICSI (Physiological Intracytoplasmic Sperm Injection), helps select sperm cells based on their specific biological characteristics.

Obstetrics and Gynecology Specialist Dr. Melih Aygün states that the PICSI method is an auxiliary laboratory technique that can be considered especially in cases of male-related infertility problems. However, he points out that there is no definitive scientific evidence that the method increases pregnancy and live birth rates in every patient.

What Is the PICSI Method?

PICSI is a sperm selection method defined as physiological intracytoplasmic sperm injection. In the conventional ICSI procedure, the embryologist selects the sperm to be injected into the egg by evaluating sperm motility and structural characteristics under a microscope.

In the PICSI method, however, a natural substance called hyaluronic acid is utilized in sperm selection. Some sperm that have completed their maturation process may exhibit the ability to bind to hyaluronic acid. This biological characteristic is used to select the sperm to be used in the microinjection procedure.

Differences Between PICSI and Conventional ICSI

In the ICSI method, a single selected sperm is directly injected into the egg cell in the laboratory environment. In the PICSI procedure, an additional stage is added to sperm selection before this process. In this stage, suitable sperm are chosen among those capable of binding to hyaluronic acid.

The main purpose of this approach is to help select sperm with certain maturity characteristics. However, it cannot be said that this biological characteristic used in sperm selection definitively increases pregnancy or live birth rates.

In Which Patients Can PICSI Be Considered?

The PICSI method may come into consideration particularly for some couples planned for microinjection treatment due to infertility resulting from male factors.

Advanced sperm selection methods can be considered for couples with significant disorders in sperm parameters or those who have experienced problems in previous treatments. However, it is not correct to decide that PICSI application is necessary based solely on spermiogram results.

In treatment planning, the couple's previous pregnancy and treatment history, the woman's age, egg quality, and other factors that may cause infertility should also be taken into consideration.

Does PICSI Increase IVF Success?

Studies conducted on the PICSI method have examined fertilization, pregnancy, miscarriage, and live birth outcomes. Some studies have reported possible differences in miscarriage rates in certain patient groups. However, it should be considered that these findings may not be applicable to all patients.

In large-scale clinical studies, it has not been demonstrated that the PICSI method increases live birth rates compared to standard ICSI in couples undergoing ICSI due to male-factor infertility.

For this reason, PICSI should not be considered a standard application that definitively increases success in IVF treatment. The use of the method should be considered in line with the couple's clinical characteristics and current scientific evidence.

The Importance of Proper Sperm Selection in Male Infertility

Sperm selection is one of the important stages of assisted reproductive treatments. However, a successful pregnancy does not depend solely on the characteristics of the selected sperm. Egg quality, the chromosomal structure of the embryo, uterine health, and embryo transfer conditions are also among the factors affecting the pregnancy outcome.

The necessity of advanced sperm selection techniques used in male infertility should be evaluated in line with current scientific evidence and the individual characteristics of the couple.

Providing accurate and realistic information about methods such as PICSI helps couples make informed evaluations of their treatment options.
