Sperm Freezing

Just like egg freezing, sperm freezing nowadays is also not so uncommon. If a man wishes to freeze his sperm due to any reason, he can consult his doctor for it. The freezing of sperm occurs through the method of cryopreservation. Cryopreservation involves preserving the tissues at a very low temperature (-196°C) in liquid nitrogen. At such low temperatures, the cellular activities stop and the tissue remains unchanged. The person might want to store his sperm before going for a vasectomy or might want to donate it. 

About Sperm Freezing

Before undergoing sperm freezing, the person needs to undergo a diagnosis of diseases like HIV. This is a necessary step to avoid any infection. Moreover, the person undergoing sperm freezing must give written consent along with how the sperm can be used. They can either preserve it only for themselves or donate them to the sperm banks. moreover, they also have to write for how long they wish to store their sperms in the bank.10 years is the standard storage time, however, it can expand up to 50 years. It depends upon the condition of the sperm as stated by the andrologists.

For this procedure, the person will be asked to give a fresh sample of semen to the andrologist. Then the doctors will send it for cryopreservation. The sample gets mixed with a suitable cryoprotectant. This will protect the sperm from any damage. Moreover, the samples will be separated into several straws making many containers. Thus, there will be chances of using it multiple times. In the last step, these sperms will remain stored in liquid nitrogen at a temperature of -196 °C.
