title: [Effect of heterologous seminal plasma on the improvement of the quality of the ejaculate].
abstract: Seminal plasma from oligozoospermic ejaculates and ejaculates with high rate of pathological spermatozoa was substituted for seminal plasma from normal ejaculates in experiments carried out in order to improve the ejaculate quality. In these experiments the improvement of ejaculate quality could not be established. The progressive increase of 20% in the motility of spermatozoa was recorded, in 4 out of 7 ejaculates with hypokinetic motility of spermatozoa where plasma was substituted, while in one case the motility remained unchanged. When plasma from normal ejaculates was substituted for plasma from ejaculates of poorer quality, the intensity of the motility of spermatozoa decreased for 10-20% in 3 of cases while in 1 it remained unchanged. Deep freezing of ejaculates after seminal plasma was substituted did not gain satisfactory results except when cases of substitution for plasma from normal ejaculates were concerned.
