Abstract
PREVIOUS investigations1–3 have shown that fertilized rabbit ova stored at 10° C. or at 0° C. for various lengths of time can develop into normal young when transferred into recipient rabbits. A recent experiment4 has further demonstrated that freshly ovulated unfertilized ova can be kept at 10° C. or at 0° C. for 48–72 hr. without all losing their fertilizability when transferred into the Fallopian tubes of rabbits which had been bred twelve hours before. This communication reports the subsequent fertilization and the probability of normal development following the transfer of unfertilized ova which had been stored for certain lengths of time.
