Ovulation in light-estrous rats induced by darkness.
Adult female rats show continual vaginal cornification and cease ovulation a few weeks after they are exposed to continuous lighting (light-estrous rats). When these rats were placed in the darkness for 10 hr, 80% of the animal ovulated approximately 46 hr later. Peripheral LH increased to a small peak immediately after placing in darkness concomitant with a decrease in pituitary LH content; a ...
متن کاملNeonatal handling induces anovulatory estrous cycles in rats.
Since previous work has shown that stimulation early in life decreases sexual receptiveness as measured by the female lordosis quotient, we suggested that neonatal handling could affect the function of the hypothalamus-pituitary-gonadal axis. The effects of neonatal handling on the estrous cycle and ovulation were analyzed in adult rats. Two groups of animals were studied: intact (no manipulati...

15 صفحه اولDo Norway rats (Rattus norvegicus) synchronize their estrous cycles?
Estrous synchrony was tested using 10 pairs of sibling female rats (Rattus norvegicus). A Monte Carlo bootstrap simulation was used to construct random control groups to avoid previous statistical errors and to test for significance when there are irregular cycles. The 10 pairs of females did not exhibit estrous synchrony. The effect of cycle irregularity on the limits of synchrony was analyzed...
متن کاملInducing Early Estrous and Ovulatory Cycles
The goal of any breeding operation is to maximize reproductive efficiency and minimize the cost of producing live offspring. The reproductive performance of broodmares can be assessed by determining pregnancy and foaling rates for a season or, preferably, for each cycle. Mean pregnancy rates per cycle are 50% to 60% under current management conditions. However, the rates vary widely depending o...
