The prepared sperm is placed into a special freezing solution known as a cryoprotectant in small vials. These vials are then stored in freezers containing liquid nitrogen, where the sperm is kept frozen at a constant temperature of -196°C.
Common reasons to choose sperm freezing:
Advancing age
Deteriorating sperm quality or low sperm count
Cancer or other medical conditions
Pre-vasectomy patients
Career and lifestyle choices, such as those with high-risk occupations
Before starting chemotherapy or radiotherapy for cancer treatment
