[Effect of coitus on sperm transport and fertilization in rabbits].

Abstract

The number of spermatozoa into the Fallopian tubes and levels of in vivo fertilization were measured following different treatment. The results show that copulation by the artificially inseminated animal has a strong influence on the transport of the rabbit spermatozoa and "in vitro" fertilization. This constitutes some more evidence about the physiological role played by the utero-tubal junction.
