Studies on the sperm reservoir of the pig oviduct [PDF]

open access: yes, 2003
During sperm transport in the female pig a proportion of spermatozoa are arrested, often for 24 h or more, in a particular segment of the utero-tubal junction (UTJ) and the adjacent tubal isthmus, where a sperm reservoir (SR) is built up.

Hydrodynamic study of sperm swimming near a wall based on the immersed boundary-lattice Boltzmann method

open access: yesEngineering Applications of Computational Fluid Mechanics, 2020
This paper presents a numerical study on a sperm swimming in a viscous fluid by using an immersed boundary-lattice Boltzmann method (IB-LBM). The sperm is modeled simply by integrating a slender tail and an elliptical head.
