What is Reproductive Insurance: Reproductive insurance is the practice of storing sperm in advance in a sperm bank to prevent possible irreversible damage to male sperm production, and then rewarming the sperm when needed so that the freezer can have his own children in the future. This is an effort that will benefit millions of families. The main groups of people for whom the fertility insurance is intended: 1. Men who have serious diseases such as tumors but have the need to have children. Once diagnosed, they need to come to the sperm bank to freeze their sperm as soon as possible, because the deterioration of the disease, or the treatment of drugs, can further damage the quality of sperm. 2.Men who have lost their fertility in order to prevent accidents. 3.Men who are engaged in long-term work that affects their fertility, such as those who are exposed to radioactive or toxic substances and chemicals, heavy metals, etc. 4.The sperm of patients with oligo-, weak- and malformed sperm and the epididymal and testicular sperm of patients with obstructive azoospermia are frozen and can be used for future microscopic insemination (ICSI) treatment. 5. Safety of reproductive insurance Spermatozoa may be damaged to a certain extent during the freezing and thawing process, resulting in a decrease in sperm motility; this damage may vary greatly among individuals. In general, the higher the quality of the semen, the less damage will be caused by cryo-resuscitation, and conversely, the more damage will be caused by cryo-resuscitation. Since the world’s first human frozen sperm bank was established and applied to clinical use in 1956, a large number of normal offspring have been born, which proves that frozen storage of sperm is safe and effective for sperm. Currently, frozen semen has achieved clinical pregnancy rates similar to those of fresh semen.
