PICSI (Physiological Intracytoplasmic Sperm Injection)
Selecting the Most Mature Sperm for Fertilization
PICSI (Physiological Intracytoplasmic Sperm Injection) is an advanced sperm selection technique used during ICSI (Intracytoplasmic Sperm Injection). Unlike conventional ICSI, PICSI helps embryologists select functionally mature sperm based on their natural ability to bind to hyaluronic acid (HA)—a substance naturally present around the egg.
At Santasa Fertility & IVF, we offer an advanced PICSI program as part of our comprehensive male fertility and IVF services. Our experienced embryologists use evidence-based sperm selection techniques to optimize treatment for selected couples.
What is PICSI?
In natural conception, only mature sperm can bind to the hyaluronic acid surrounding the egg before fertilization. PICSI mimics this natural selection process in the IVF laboratory.
During the procedure, sperm are placed on a special dish containing hyaluronic acid. The sperm that bind to the HA are considered more mature and are selected for ICSI.
Who May Benefit from PICSI?
PICSI may be recommended for couples with:
How is PICSI Performed?
Semen Collection & Preparation
A semen sample is collected and prepared using standard laboratory processing techniques.
HA-Dish Placement
Sperm are placed on a special hyaluronic acid-coated PICSI dish designed to mimic the natural egg environment.
Natural Binding
Mature sperm naturally bind to the hyaluronic acid, demonstrating functional maturity.
Embryologist Selection
The embryologist carefully identifies and selects the mature sperm that have successfully bound to the HA.
ICSI Injection
The selected physiologically mature sperm are injected directly into the egg using the standard ICSI technique.
Advantages & Limitations
Advantages of PICSI
- Selects physiologically mature sperm.
- Mimics the natural sperm selection process.
- May help improve sperm selection in selected male factor infertility cases.
- May be beneficial in couples with high sperm DNA fragmentation or previous IVF failures.
- Easily combined with conventional ICSI.
Limitations of PICSI
- Not all couples require PICSI.
- It does not guarantee fertilization, implantation, or pregnancy.
- Clinical benefit may vary depending on the underlying cause of infertility.
- Success depends on multiple factors, including egg quality, embryo quality, maternal age, and uterine health.
