Semen freezing, also known as sperm cryopreservation, is the process of collecting, freezing, and storing sperm for future use. It is a well-established method used to preserve male fertility, particularly in situations where sperm may be needed later for assisted reproductive techniques such as IVF or ICSI.
Fertility preservation before medical treatments (chemotherapy or radiation).
Sperm banking before vasectomy or testicular surgery.
Donor sperm programs.
Typically done through masturbation at a fertility clinic or collected at home and delivered under proper conditions.
In special cases, sperm may be retrieved surgically (e.g., PESA, TESA) before freezing.
The sample is analyzed for volume, concentration, motility, and morphology.
Results guide the freezing protocol.
A cryoprotective agent is added to protect sperm cells from damage during freezing and thawing.
Preserves fertility during medical or life events.
Allows for multiple IVF or ICSI attempts from one collection.
Reduces pressure and anxiety on the day of IVF egg retrieval.
Useful for men with fluctuating or declining sperm quality.
