diestrus

the resting period between estral periods of animals. The female rejects the male, blood levels of estrogens are minimal and progesterone levels are high. This provides a physiological state in the uterus which is most conducive for implantation and growth of the developing fetus. Diestrus is terminated by luteolytic factors, such as prostaglandin F secreted by the endometrium, if pregnancy does not occur.

At the end of treatment, the animals were sacrificed when they were in diestrus, by rapid decapitation between 1000 and 1100 hr.
Normally, the estrus cycle in rats lasts 4-5 days (16), but in the present study a high level of progesterone concentration in LDE and HDE groups enhanced the duration of estrous cycles due to longer duration of diestrus phase and shorter duration of estrus and proestrus phases in these groups.
activity measured in the estrus group was significantly higher as compared with the male and diestrus groups in all hippocampal subfields; results were similar after comparing C.
with high levels of estradiol, Group Proestrus) performed in the pool differently than females that were in a phase of the estrus cycle of low hormonal levels (specifically, either in the estrus, metaestrus or diestrus phase, all rats included under the name Group Others); this experiment also contained a third group of male rats.
The estrous cycle is traditionally divided into four phases: proestrus, estrus, metestrus, and diestrus (Figure 10-2).
The estrous cycle phase can compromise the detection of uterine discharges since the cervix is open during estrus and closed during diestrus.
Recent experiments in our laboratory have demonstrated that TGasel is expressed in vaginal epithelium of mature mice during the stages of the estrous cycle when estrogen levels are high, namely, estrus, metestrus, and diestrus.
Corpus luteum (kor-puhs loo-te-uhm) The tissue formed after ovulation that eventually will produce progesterone, the hormone that is dominant when the female is pregnant or in diestrus.
This becomes the corpus luteum that produces the hormone progesterone, which corresponds with the diestrus.
