The rabbit as a model for reproductive and developmental toxicity studies.
The rabbit has many advantages as a nonrodent and second model for assessing the effects of toxic agents on semen quality, fertility, developmental toxicity, and teratology. The male and female reproductive systems of the rabbit are described, and data on growth, sexual development and reproduction are compared with mice, rats, and humans. Techniques for semen collection and evaluation in the male, and artificial insemination, superovulation, embryo culture, and embryo transfer in the female are included as useful procedures in toxicity testing. Examples of the use of rabbits and experimental replication for toxicity testing are given. Special features of the visceral yolk sac and development of the chorioallantoic placenta of the rabbit are compared with rodents. The rabbit extraembryonic membranes more closely resemble the human than do the rodents, in some respects. The use of the rabbit in developmental toxicity and teratology studies is discussed.
