Developed to maximise sperm survival

SpermFreeze Solution is developed to maximise sperm survival and maintain DNA integrity and function after cryopreservation.

SpermFreeze Solution is egg yolk-free and contains only chemically defined components, including glycerol as a cryoprotective agent. The product also contains cholesterol, which has been found to affect the development of acrosomal responsiveness and fertilising ability in vitro1. The product is ready-to-use.

Sperm function maintained after cryopreservation

To ensure sperm function after cryopreservation, clinical data was obtained from 48 patients, including ICSI cases and patients receiving conventional IVF treatment1. The study was performed on sibling oocytes and fresh semen was used as a control.

The clinical data showed that sperm function was maintained after cryopreservation. There was no statistical difference between the performance of cryopreserved semen compared to fresh semen, see figure to the right.

SpermFreeze Solution maintains DNA integrity

Several studies show a negative correlation between defective sperm chromatin structure and fertility, both in vivo1 and in vitro2 . To ascertain that SpermFreeze Solution maintains DNA integrity, semen samples from 22 patients were tested in a sperm chromatin structure assay after cryopreservation using SpermFreeze Solution.

The study confirmed that cryopreservation using Vitrolife's SpermFreeze Solution maintained DNA integrity3.
