London: Scientists have apparently found a new technique for rapidly freezing sperm that could be a fresh hope to couples undergoing IVF.Experts have discovered that fast-freezing sperm preserves far more of its motility than present slow-freezing method, reports the Independent.
The experts from Chile and Germany said that slow-freezing techniques have several drawbacks, and retain only about 30 percent to 40 percent of sperm activity.However, rapid freezing, also known as vitrification, allows that figure to rise to almost 80 percent.Vitrification is already used to quick-freeze eggs and embryos with success, allowing spare ones to be used in IVF at a later date.The findings will be presented at the World Congress of Fertility and Sterility in Munich.
