sperm cryopreservation

Sperm cryopreservation is a process where sperm cells are frozen at very low temperatures to preserve them for future use. This technique allows men to store their sperm securely without deteriorating quality, making it useful for medical treatments like chemotherapy or procedures like vasectomy. When needed, the frozen sperm can be thawed and used for fertility treatments such as insemination or in vitro fertilization. The process involves collecting a sperm sample, adding a special cryoprotectant to prevent damage from ice formation, and then gradually cooling it before storing it in liquid nitrogen.
