According to the research data of an international research group, the number of male sperms in the countries in progress is also reduced from 1973 to 2011, including north america, australia, new zealand and parts of european countries, by 52%, from about 9900 million sperms per ml to 4700 million sperms per ml, at a slower rate than in developed countries. This report has raised worldwide concerns and therefore the preservation of male fertility will become a major public health problem in the near future. Male infertility can be classified into primary infertility and secondary infertility. The research shows that genetic factors are important influencing factors, and the genetic mutation or the genetic deletion of methionine synthetase reductase gene, CLOCK gene and the like, SOHLH1 and the like are all reasons of primary male sterility. Secondary male infertility is mainly caused by environmental pollution, bad living habits, harmful exposure and the like, and with the continuous increase of environmental pollution, age and living pressure, more and more males suffer from abnormal sperm quality and incapability of bearing. With the release of the national second birth policy, the nation encourages people to breed more offspring, and the need of people for breeding is more and more urgent. In summary, the incidence of male infertility is gradually increasing and attracting human attention, and fertility preservation is an urgent clinical need. For patients with oligoasthenospermia, a small amount of high-quality sperms obtained by manual screening are very precious, and for patients with azoospermia, a very small amount of sperms obtained by puncturing or operation are more hoped for the sperm to grow, so the preservation of the sperms is very important, and therefore, the oligospermia or poor sperm quality caused by environment, living habits or unknown reasons exist in clinic, many patients have fertility requirements, and an effective method for freezing and storing few sperms is urgently needed.
