1-3 yrs
gestation
19-21 days
estrus cycle
4-5 days

Lee Boot Effect
Housing female mice in groups will result in synchronization of estrus cycles. Prolonged absence of male pheromones results ina state of anestrus.
Whitten Effect
Estrus can be induced in most group housed females by adding male mouse urine to their cage.
Bruce Effect
Pheromones from a strange male can prevent the implantation of embryos into the uterine walls of a recently bred female. This is why one should not move a female from one male's cage to another.
Facultative Effect
The developmental arrest induced by environmental conditions related to the survival of the dam and her ability to nourish developing embryos. Females that are bred postpartum estrus have an extended gestation period.
