GROUPING AND OVULATION IN MICROTUS PENNSYLVANICUS

in Reproduction

Summary.

Female voles, Microtus pennsylvanicus, were caged singly or in groups from weaning to 60 days of age, when they were paired for 72 hr with males. The incidence of coitus and ovulation during pairing was independent of prior housing conditions, but adrenal glands, ovaries and uteri were lighter and fewer CL were formed among previously grouped females. Stimuli associated with all-female groups, therefore, may inhibit coital induction of ovulation and development of reproductive organs in this species.
