## Abstract A procedure using published surgical techniques is described for determining the effects of antiplasma membrane antibodies on spermβegg binding, penetration, and fertilization in vivo in the domestic pig. Time of ovulation was controlled and sperm inseminated at precise times relative t

Abstract
Sperm surface isoantigens can be detected on the surface of fertilized eggs by using cytotoxic (complement dependent) spermβspecific isoantisera. These isoantigens cannot be detected on unfertilized eggs. This may indicate their transfer from sperm to egg during fertilization.

## Abstract Rat epididymal spermatozoa, at a concentration of 40β65 Γ 10^4^ cells/ml, were preincubated for 5β5.5 hr and then added to eggs from superovuβlated, immature rats. By 10β12 hr after insemination, 86% of the eggs had undergone fertilization, but many of them (41%) were polyspermic. When
Parthenogenetic embryos, which are produced by the spontaneous or artificial stimulation of the oocyte, partially develop in the complete absence of the male gamete but fail to produce live young in many mammalian species. The identification of developmentally regulated molecules on the cell surface
