Here are some of the possible causes of a man's desire to freeze his sperm:

• Initiation of chemotherapy treatment.
• At the time prior to surgery that compromises your ability to ejaculate.
• When the man anticipates prolonged absences and wants to leave samples so that his partner can start assisted reproduction treatment.

It is a simple procedure that simply requires masturbation and collection of the sample in suitable containers and subsequent shipment to the chosen centre for freezing and maintenance.

It is important to note that samples can remain frozen indefinitely until the man decides to stop keeping the sample frozen or to use it for assisted reproductive treatment.
