title: Effects of ions and K+:Na+ ratio on motility and oxygen consumption of human spermatozoa.
abstract: Variations in the osmolarity of the medium altered motility, velocity, and oxygen consumption of human spermatozoa. Variations in the K+:Na+ ratio also altered their motility and velocity. These alterations, which reflect both the composition of the medium and individual characteristics of the donor, are discussed in relation to the diversity of milieu through which the sperm are transported.
