Abstract
ROWLANDS1 described the recovery of ‘rats eggs by unravelling the Fallopian tubes and squeezing out their contents under low-power magnification. Using this method he obtained an average of 4·9 ± 0·5 (standard error of the mean) ova per rat from the tubes of thirteen normal rats two days after mating2. Using the same method in forty rats killed 0–2 days after mating, we recovered a similar number of eggs (4·2 ± 0·3 per rat).
