%X Merino ewes were artificially inseminated during either early or late oestrus and were killed 4 or 24 hr after insemination. Insemination during late oestrus resulted in fewer spermatozoa in the cervix, the uterus, and the fallopian tubes and in a lower fertilization rate. Increased resistance of the cervical mucus to penetration by spermatozoa during late oestrus appeared to be responsible for these effects.
