Human sperm bank has always been a very mysterious place, do you know that human sperm bank can also do self sperm maintenance in addition to voluntary sperm donation? The establishment of human sperm banks has promoted the development of assisted reproduction technology and brought hope for fertility to patients with severe oligospermia and weak spermatozoa and azoospermia. Human sperm bank business is divided into donor sperm business and self-sperm conservation business. In the past ten years, human sperm banks in China have developed rapidly in the sperm donor business, and their contribution to assisted human reproduction has been widely recognized. However, the development of self-sperm conservation business is relatively slow compared to foreign countries. The main reasons for this are the following three: 1. Insufficient publicity, most people in China do not know about human sperm banks’ self preservation business. 2. overestimating the cost of self preservation, thinking that self preservation will bring a great financial burden; 3. fluke mentality, thinking that the quality of semen is good now and will be good in the future, and that accidents will not happen to them; In view of the above, today we will introduce the self preservation business to you in detail. First of all what is self sperm preservation? Self-semen preservation means that semen is taken out of the body in advance, processed and then frozen and stored in liquid nitrogen (-196℃) in a sperm bank, and then taken out and revived for use when needed, making it possible for the applicant for preservation to obtain his own offspring through assisted reproductive technology (artificial insemination or IVF technology). What are the groups of people who are suitable for self-seminal preservation? 1, men who have no short-term reproductive plans for eugenic purposes; 2, men in high-risk occupations; (police officers, firefighters, military personnel, competitive athletes, action film actors, etc.) 3, before exposure to substances known to cause serious reproductive toxicity, or substances predicted to cause reproductive toxicity; (chemical plant employees, plastic factory employees, radiologists) 4, patients before surgery affecting the testes, prostate and ejaculation 5. Patients with oligospermia or sperm discharge disorders who need to have children; 6. Patients with puncture sperm extraction or microscopic sperm extraction; 7. Cancer patients (before chemotherapy, radiotherapy and surgery). Why do I need a medical examination before doing autosperm conservation? Since the semen of all self-preservation applicants will be stored in a liquid nitrogen tank after being loaded into their respective freezing tubes, the following medical examinations are required for each self-preservation applicant to prevent the risk of cross-infection: blood type, HBV, HCV, HIV, TP, UU, CT, NG tests. The Human Sperm Bank agrees with the applicant’s examination done within six months at a hospital of second class or higher or a specialized hospital. However, the Human Sperm Bank is required to keep a copy of the laboratory test. What is the application procedure for self-sperm conservation? 1. Applicants for self-sperm freezing for the purpose of assisted reproductive technology should be married; it should be the common will of both spouses. The couple is the co-applicant for self-seminal deposit. Application for self-sperm freezing should provide the original identification and marriage certificate of both husband and wife respectively. The human sperm bank retains copies of the above documents. 2. For the purpose of reproductive insurance, the applicant can be a single male or a couple applying together. Single men applying for self-sperm preservation should provide the original proof of identity. Husband and wife applying together should provide the original proof of identity and original marriage certificate of both spouses respectively. The Human Sperm Bank keeps copies of the above documents. 3. Fill out the application form for self-sperm conservation and sign the informed consent and conservation agreement (two copies, one for the applicant and one for the human sperm bank). In recent years, China’s human sperm bank has developed very mature sperm preservation technology, which has largely reduced the damage to sperm in ultra-low temperature. Microscopic sperm retrieval techniques have also been developed for patients with oligozoospermia and azoospermia, which can significantly increase the fertility hopes of patients. The Human Sperm Bank also intends to contribute to human fertility preservation for the greater benefit of self-preservation patients. Patients interested in self-preservation are invited to visit the major sperm banks for consultation and can visit their official websites.
