Oil-mediated nano emulsion, a more advanced technology than other commercial extenders, will protect spermatozoa for extended periods against ROS and cryo injuries. The study is designed to elucidate the most suitable extender to preserve infertile subjects' sperm cells against ROS damage. This is a significant step forward for the andrology society, as it introduces the use of a nano emulsion extender (natural oil extract) for the first time, particularly for those who are undergoing urology-related defects. The study involved forty-four (44) infertile subjects with smoking habits and forty-two (42) fertile subjects without smoking habits, as per CASA guidelines. Semen preservatives (glycerol and egg yolk citrate), along with our naturally derived nano emulsion components (CN, EN, and EL), were prepared and used to preserve the semen sample for 24 hours. Standard semen parameters (morphology, viability, and integrity), ROS, and sperm acrosome state by staining were measured before and after cryopreservation. The results indicated that the morphology and motility of sperm features were better maintained in the CN-oil-mediated nano emulsion than in other emulsions, and ROS-induced DNA damage was reduced.
