The purpose of this study is to theoretically investigate the electro-magneto-biomechanics of the swimming of sperms through the cervical canal in the female reproductive system. During sexual intercourse, millions of sperms migrate into the cervix in large groups, hence we can approximately model their movement activity by a swimming sheet through the electrically conducting biofluid. The Eyring–Powell fuid model is considered as the base fuid to simulate male’s semen with self-propulsive sperms. An external magnetic feld is applied on the fow in transverse direction. The governing partial diferential system of equations is analytically solved. Creeping fow regimen is employed throughout the channel due to self-propulsion of swimmers along with long wavelength approximation. Solutions for the stream function, velocity profle,
and pressure gradient (above and below the swimming sheet) are obtained and plotted with the pertinent parameters. The prominent features of pumping characteristics are also investigated. Results indicate that the propulsive velocity is reduced with an increase in the electric feld which is an important feature that can be used in controlling the transport of spermatozoa inside the cervical canal. Not only is the present analysis valid for living micro-organisms, but also valid for artifcially designed electro-magnetic micro-swimmers which is further utilized in electro-magnetic therapy taking place in a female’s lubricous cervical canal flled with mucus. |
