ABSTRACT. The number of spermatozoa required to obtain conception by intratubal insemination in dogs was examined. Three groups consisting of 5, 8 and 8 dogs received 0.5 * 10E6, 2.0 *10E6 and 4.0 * 10E6 spermatozoa respectively, into each uterine tube. No conception occurred in the 5 animals inseminated with 0.5 * 10E6 spermatozoa, but conception occurred in 6/8 (75.0%) and 3/8 (37.5%) dogs inseminated with 2.0 * 10E6 and 4.0 * l0E6 spermatozoa, respectively. Among the pregnant animals, three aborted (33.3%) and the mean number of newborns was small, 2.5 =+- 0.5 (SE). One acardiacus anceps was observed with normal fetus in one animal with a Caesarean delivery.
