Fertilization of pig eggs in vivo and in vitro.

Abstract

The objective of this review is to set some of the problems associated with attempted in-vitro fertilization of pig eggs in a perspective drawn from the results of studies in live animals. Accordingly, the first part of the paper summarizes a variety of classical and more recent experiments performed in viva whilst the second part examines in-vitro observations and the nature of the experimental conditions imposed. A more general discussion follows in which suggestions are made ffir future work. It should be emphasized that this review does not attempt an exhaustive citation of relevant publications. None the less, it is hoped that sufficient references are given to provide access to the main body ofliterature available up to December 1988. Taken in conjunction with previous reviews having a different orientation (Hancock, 1962; Alanko, 1973; Baker & Polge, 1976; Polge, 1978; Einarsson, 1980: Hunter, 1982), a majority of studies bearing on the process of fertilization in pigs should become accessible.
