Abstract Objective: To evaluationthe of the biotoxicity on sperm of condom in the market mainstream. Methods: 1.0 ml sperm application liquid was added into the condom, and the number of oil droplets was counted after 3 minutes of oscillation. The sperm motility rate was measured after 5 minutes and 60 minutes respectively, and the sperm motility rate was compared with sperm in sperm application liquid non-contacted the condoms during the same time. Results: The sperm survival index of 18 in these 23 models condoms was less than 0.8 after 5 minutes of sperm contacted condom, and the sperm survival rate of these 23 models condoms was less than 0.8 after 60 minutes of sperm contacted condom. The number of oil droplets of condoms had gradually decreased or disappeared over time. Conclusion: 23 models condoms from 16 brands all have sperm toxicity, and the toxicity degree is related to the brand, condoms model, and time of sperm contacting condoms. When condoms used for human assisted reproductive technology (ART), it should be chosen condoms with no spermicide and oil-free, and sperm biotoxicity test of condom is necessary for help to choose the condom with low sperm biotoxicity.
