Diluted semen can be stored at -196°C and be used successfully for more than 10 years after cryopreservation.
When should you undergo semen storage?
▪ Couples who want to receive artificial reproduction treatment but temporarily live in different locations
▪ Men who want to receive a vasectomy
▪ Those undergoing cancer, surgery, or medical procedures
▪ Those with low sperm counts
▪ Those who cannot provide semen on the day of ovum retrieval day
▪ A semen donor
Notice:
Individuals who want to receive assisted reproductive treatments would need to first undergo the VDRL and HIV blood test. A valid marriage certificate is also necessary for those who want to receive test-tube baby treatments.
Q&A
1. How long does frozen sperm last?
As long as the average freezing temperature conditions (-196°C) remain constant, sperm can survive the process indefinitely. Frozen semen can be stored for several years without additional sperm deterioration beyond that caused by the original freezing process. Due to Taiwan’s policies, however, written consent will be required to extend the storage period.
2. What are the differences between frozen sperm and fresh sperm?
The thaw survival of sperm is over 50%. Once thawed, the sperm will need to be processed to be used in any subsequent procedure. It is still strongly recommended to use fresh sperm while undergoing IVF treatments.
