Vial Quality

At Cascade Cryobank, we take pride in providing our recipients with the purest and highest quality donor sperm vials available. We strive to lead in the industry by using the most up-to-date and advanced technology.

Gradient Column

Our labs use a gradient column for sperm isolation/purification. This helps us separate highly motile sperm cells from other unwanted elements in seminal fluid, which can cause uterine irritation following the IUI procedure and may impair fertilization. With column purification, cells with the highest motility are isolated from cells with reduced motility, immotile cells, and other acellular debris. With this method, we can provide the cleanest and highest-quality samples to our recipients.

Cryopreservation Media

Our labs also use state-of-the-art cryopreservation media, which helps maintain DNA integrity and the cellular function of sperm cells. The cryopreservation media works primarily by preventing ice crystal formation within sperm cells and stabilizing cell membranes during the freezing and thawing process. Ice crystals can damage cells and decrease motility and viability. Furthermore, during the freezing and thawing process, sperm cells can endure oxidative stress. Our media contains antioxidants to help to protect the sperm cells from oxidative injury and maintain DNA integrity.
