Semen vitrification is an advanced cryopreservation technique that rapidly freezes sperm cells to minimize damage, providing better preservation compared to traditional freezing methods. This innovative method helps maintain sperm quality for future fertility treatments.
Semen vitrification involves rapid cooling and solidification of sperm samples without ice crystal formation, which can damage cells. This technique improves sperm survival and viability during the freezing and thawing process.
A semen sample is collected through masturbation into a sterile container in a controlled environment to ensure sample quality.
The sample is analyzed for sperm count, motility, and morphology to assess sperm quality before vitrification.
If necessary, the sample is processed to concentrate sperm and remove seminal fluid, optimizing it for freezing.
A cryoprotectant solution is mixed with the semen sample to protect sperm cells during rapid freezing.
The treated sample is placed on specialized devices (cryoloop/cryotop) and rapidly cooled by direct immersion into liquid nitrogen.
Vitrified samples are stored long-term in liquid nitrogen tanks at ultra-low temperatures to maintain viability.
When needed, samples are thawed carefully for use in ART procedures like IVF or IUI based on individual fertility requirements.
Semen vitrification is a cutting-edge option for preserving male fertility with potentially improved success rates. Consult a fertility expert to determine if this technique suits your fertility preservation needs.
