If you want to go for sperm freezing, particularly long-term freezing, you want to go to a sperm bank, and at the sperm bank, they will do what’s called infectious disease screening, which will screen you for things such as hepatitis, HIV, syphilis before the process. Then once you’ve got your infectious disease results back then you need to go back to the sperm clinic of the sperm bank, and masturbate in a cup. Most men that masturbate in the cup would have at least four vials of sperm to freeze if they have a good volume of ejaculate. Sometimes if the volume is low, there may only be one vial. So the question becomes how many vials you need in the future.
If you’re going to be using that sperm for what we call artificial insemination for your partner in the future, you may want to have at least 4-6 vials of sperm frozen for the future, because artificial insemination sometimes takes 3-4 inseminations before most women are successful. I always tell my clients the more vials the better. Sometimes this will have to be done over a period of time. So for example, over a week period, as long as you have at least one to two days of absence in between the collections; that’s enough time. But as to why it’s important; if you’re faced with a diagnosis of cancer or surgical removal of the testicles that you plan well in advance prior to the treatment to freeze the sperm, because you may need multiple visits to have enough sperm to freeze for the future.
How is sperm frozen in the IVF laboratory?
Male patients can freeze their sperm for use in their own future IVF treatment or to donate to a sperm bank. Before you can have your sperm frozen your genetic material would require testing.
