What it is?

Sperm freezing This process is being used since the 1960s. It is a very common and effective method of preserving male fertility in patients who are at risk or for donation to another couple.

Who can do it?

• Males who have low sperm count, obstructive azoospermia or the quality is deteriorating.
• Men who are undergoing radiotherapy or chemotherapy treatments for malignant diseases or vasectomy, etc.
• If you are undergoing vasectomy and want the sperm to be available if you change your mind in the future.

How we do it?

Primary screening: A fresh sample of semen will be tested for any abnormalities or disease.

Sample collection: Usually the sample is provided by masturbation. The number of samples frozen will depend on your age, semen quality, partner’s fertility status, etc.

Freezing the semen: The sample will be mixed with a “cryoprotectant”, which will protect the sperm from formation of ice crystals. The sample will be divided and stored in a number of containers. This is done so that not all the sperm needs to be thawed and used at the same time. You can use different containers for multiple treatments. The containers are then cooled and stored in liquid nitrogen at
-196⁰C.
