Medical devices for human assisted reproductive technology Human sperm survival test1 ScopeThis document describes the test methods for human sperm survival of medical devices used in human assisted reproductive technology, including human sperm motility test test, human sperm motility recovery test and human sperm cryopreservation test. The human sperm motility test is applicable to the evaluation of culture fluids and instruments that are in direct contact with sperm in medical devices used in human assisted reproductive technology. Toxicity risks that may arise from instruments/consumables. According to the situation, evaluate the possible sperm toxicity risk of culture fluids and instruments/consumables. The human sperm motility recovery test is suitable for evaluating the possible toxicity risk of sperm brake fluids and similar products. To evaluate the potential toxicity risk of sperm brake fluid or similar products and to determine the recovery of sperm vitality after direct contact with sperm brake fluid or similar products. The human sperm cryo-thawing test is suitable for evaluating the sperm toxicity and cryo-thawing injury risks that may be caused by human sperm cryopreservation products. By observing the direct contact between sperm and sperm freezing solution and the recovery of sperm vitality after freezing and thawing, it is possible to judge whether the sperm freezing solution product has Risk of toxicity and cryo-thawing injury.2 Normative referencesThe contents of the following documents constitute essential clauses of this document through normative references in this document.
