Background
Embryo freezing is one of important technical means for preserving embryos for patients by human assisted reproductive technology, and can effectively improve the cumulative pregnancy rate of each egg taking period. The vitrification freezing technology can effectively reduce the cell freezing damage and improve the survival rate and the success rate of pregnancy of the embryos or ova after the freezing recovery. Is a method for quickly freezing embryos or ova, which is commonly used in the technical field of assisted reproduction at present. However, in the laboratories of different centers in reproductive medicine, the freezing-thawing effect of embryos is different and may be related to the freezing carrying rods used in different laboratories. At present, most of the reproductive centers in China mainly use three types of vitrification freezing carrying rods, namely an open carrying rod, a semi-closed type and a closed type commercialization carrying rod. The semi-closed type is to firstly invade liquid nitrogen and then to close, and the open type carrying rod and the semi-closed type carrying rod enable the embryo to be in direct contact with the liquid nitrogen when the embryo is frozen and stored, so that potential safety hazards of the embryo can exist. For human reproductive centers, the safety of embryos is very important, cross contamination between embryos can exist, or embryo contamination caused by microbial contamination due to the existence of liquid nitrogen, so that the use of a closed freezing carrier is particularly necessary.
