- Sperm Cryopreservation - Process -
Obtaining the semen sample Semen samples are collected in a sterile container. It is recommended that patients abstain for at least three days, but not more than ten days. In patients who cannot ejaculate on their own, samples can be collected using vibratory stimulation or testicular sperm aspiration. Semen Analysis Once collected, semen samples are analyzed for volume, viscosity and pH levels, and microscopically evaluated to determine motility, sperm count, morphology and other important factors. Semen Cryopreservation Cryoprotectant is added to the semen to control sperm damage caused by freezing. The specimen is then divided into individual cryo-vials, placed into liquid nitrogen vapor for 3 hours, and then plunged into liquid nitrogen. At a temperature of -196°C all metabolic activity is halted. Semen can thus be preserved for many years.
