Detailed explanation of the whole process of sperm extraction by sperm extraction machine In modern reproductive health technology, sperm extraction machine is widely used in human sperm extraction, animal artificial insemination and other fields. So, how exactly does the sperm extraction machine extract sperm? Below we will elaborate on the working principle, preparation, operating steps and precautions of the sperm extraction machine. 1. The working principle of the sperm extraction machine. The sperm extraction machine is a mechanical device. Its principle is to use a negative pressure tube to suck male semen out of the penis opening. In the sperm extraction machine, a negative pressure tube is attached to the surface of the penis and establishes a certain negative pressure, thereby promoting the discharge of semen.
