In natural conception, millions of sperm undergo a highly selective process, allowing only the most functionally competent sperm to reach and fertilize the egg.
In the laboratory setting, sperm preparation is traditionally performed using density gradient centrifugation (DGC), where sperm are separated through layers of different densities. While this method is widely used and effective, some studies suggest that centrifugation may increase oxidative stress, which can potentially impact sperm motility and DNA integrity.
Elevated sperm DNA fragmentation has been associated with reduced blastocyst development, impaired embryo quality, and a higher risk of miscarriage in certain cases.
For our patients, we incorporate advanced sperm selection techniques as part of a modern, individualized approach to assisted reproductive technologies (ART). Our goal is not only to select motile sperm, but also to preserve genetic integrity and optimize overall sperm quality.
By combining established methods with innovative technologies, we aim to create the best possible conditions for fertilization, embryo development, and successful pregnancy outcomes.
Selecting high-quality sperm is a key factor in the success of assisted reproductive treatment. We use advanced technologies such as microchip-based sperm selection (microfluidics) to isolate sperm with superior motility and improved DNA integrity.
This approach supports optimal fertilization conditions and contributes to better embryo development and overall treatment outcomes.
Microchip sperm selection (microfluidics) is an advanced laboratory technique designed to isolate sperm with high motility and improved DNA integrity under conditions that mimic the natural selection process.
By avoiding centrifugation, this method helps reduce oxidative stress and supports the selection of sperm with better functional quality for fertilization.
It can be particularly useful in selected cases, such as male factor infertility, elevated sperm DNA fragmentation, or previous unsuccessful IVF cycles.
Men with compromised sperm quality:
Targeted selection of sperm with higher motility and better DNA integrity can be particularly relevant in cases of male factor infertility, supporting improved fertilization conditions.
Couples with repeated implantation failure:
In selected cases, microchip-based sperm selection (microfluidics) may help identify sperm with improved genetic quality, which can positively influence embryo development and implantation potential.
Previously low fertilization rates:
When low fertilization rates have been observed, more precise sperm selection may enhance fertilization outcomes and support improved chances of pregnancy.
The application of this innovative technique is tailored to each specific case and thoroughly discussed with patients during consultations with Dr. Roukoudis. This ensures a customized approach to achieve the best possible outcomes for everyone.
