Nanoparticles (NPs) are small size molecules. It is divided into organic and inorganic. Organic NPs have many clinical uses, from inoculation to homeostasis, long-term storage and delivery to the system, and absorption of topically used drugs into the skin. Inorganic NPs can be used in intraoperative lymphatic scanning, tumors, and anemia treatments. NPs have a favorable effect on sperm motility, kinematic parameters or membrane integrity rates, they can also be used as antibacterial, antiviral and antifungal in genital organ diseases. There are many studies in which the addition of NPs can be beneficial or harmful to sperm. Researchers have stated that it may be beneficial or cytotoxic depending on in vivo (such as airway, skin or injection) or in vitro use. It has been reported that NPs have positive effects on motility, kinematic parameters, plasma membrane integrity, DNA damage and acrosomal integrity and can be used as an antioxidant. In addition, it has been reported that it can be used in sexsorting, bioimaging and nanopurification, and that more studies on NPs will increase in the coming years.
