👉 Spermadictyon is a type of sperm that has been identified in the laboratory, typically produced by sperm cells of male organisms and is found only within the female reproductive system. It is characterized by its unique structure and function, which allows it to fertilize eggs without the need for an intermediate male sperm. This type of sperm adhesion is known as adhesin binding and is essential for sperm's ability to penetrate and engage in sexual reproduction with females.
