Advantages to female rodents of male-induced pregnancy disruptions.
Several, not mutually exclusive, hypotheses have been discussed to account for the advantages of pregnancy disruptions for female rodents. Those hypotheses focusing on differential male behavior to related and unrelated pups may, with additional research, provide the most plausible explanation for the changes throughout pregnancy in the probability that a female will reabsorb a pregnancy when exposed to a new male.
