Sperm freezing

Who needs sperm freezing?

Men who are having treatment that might impact on their future fertility, for example chemotherapy or radiotherapy, urological surgery or undergoing a vasectomy.

Men with low sperm counts whose partners are going to have ICSI treatment may be advised to freeze sperm in case they are unable to produce sufficient sperm on the day of egg collection.

Sperm are initially stored for ten years, but storage may be extended to 55 years in certain circumstances.

Frozen sperm is usually used in conjunction with IVF or ICSI, depending on the quality and post thaw survival.
