Abstract/OtherAbstract:
Reproductive performance was characterized in females of a line of mice homozygous for a recessive mutation with a major effect on growth, the high growth (hg) mutation. Specifically, the age at onset of puberty, length of the estrous cycle, ovulation rate, and gestation length in high growth (HG) mice were determined and compared with control mice. HG females reached puberty at an age similar to control animals, exhibited normal ovulation rates and estrous cycle length, but had a shorter length of estrus. Number of fetuses at Day 17 of gestation was greater and gestation length was longer in HG females. The HG females exhibited a variety of reproductive disorders, including increased incidence of repeated detection of mating plugs without intervening pregnancy ("replug"), increased incidence of repeated detection of mating plugs within an interval of 1-8 days without intervening pregnancy ("recycle"), increased interval between pairing with a male and detection of the first mating plug, increased interval between mating and conception, increased postnatal mortality, decreased litter size, and increased incidence of vaginal septum.
