The structure of sperm tail is closely related to its motor function, which directly determines whether the sperm can be normally transported to fallopian tube and fertilize the ovum. The formation and development of sperm tail is a very complex process, which is finely regulated by various kinds of proteins. Research finds that defects of various sperm tail development related proteins can lead to oligospermia, asthenozoospermia and teratospermia. Based on the ultrastructure of sperm tail, we summarize the recent research progress of the proteins related to sperm tail development, thereby providing the theoretical basis and practical possibility for the diagnosis and treatment of male infertility.
