1992 Apr The concentration of cellular ER mRNA was 3-fold greater on proestrus than on the other days of the estrous cycle, suggesting that the increased concentration of ER on proestrus was In response to the elevated Estradiol level, Luteinizing Hormone (LH) and Follicle Stimulating Hormones (FSH) are released from anterior pituitary into the circulation

When all 4 stages (proestrus, estrus, metestrus, and diestrus) need to be identified, vaginal cytology is regarded as the most accurate method

He also used: anestrus, nonbreeding season when reproductive organs are quiescent; proestrus, animal coming on heat; metestrus, in the absence of conception, when estrus changes in the Female mice were tested during the metestrus and diestrus phases of the estrous cycle, which are characterized by low levels of estradiol and progesterone, to prevent any hormone-induced effects During the estrous cycle the predominant estrogen secreted by the ovary is estradiol-17β
After a 2-week stabilization period, ovariectomized mice were injected subcutaneously with β-estradiol (E 2, 200 ng/mouse, Sigma-Aldrich, St
Blue arrow indicates the ideal time of vaginal drug administration to maximize the drug concentration in gynecological tissues
During proestrus the CL regresses (progesterone declines) and a preovulatory follicle undergoes its final growth phase (estradiol increases)
There was a positive correlation between LTF mRNA expression in the genital tract and serum estradiol (E2) concentrations
In the other hand, metestrus/diestrus phases in mice are most comparable with the menstrual phase in humans and may be a suitable model for human endometriosis
Here, we have refined a minimally invasive model of endometriosis using naturally cycling mice (donor and recipient matched for cycle phase) to investigate lesion development in two different strains (C57BL/6 and BALB/c), induced in estrous stages of high and low estrogen (proestrus or estrus, respectively), and with varying amounts of donor In summary, data obtained from the present study provide, to our knowledge, the first evidence that HGF, HGFA, and MET expression in mouse uterus changes during the estrous cycle in a stage-, cell type-, and compartment-specific manner under the influence of estrogen and P 4

Ovarian hormone fluctuations over the rodent estrous cycle and the human menstrual cycle are known to significantly impact brain physiology and disease risk, yet this variable is largely ignored in preclinical neuroscience research, clinical studies, and psychiatric practice
The EstrousNet algorithm exploits the temporal dimension of the hormonal cycle by fitting classifications to an archetypal cycle, highlighting possible

During the estrous cycle the predominant estrogen secreted by the ovary is estradiol-17β
The mouse estrous cycle was determined through the vaginal smear assay as in previous studies [41,42]
Therefore, we think that the observed trends in serum estradiol and testosterone are representative of the actual changes during the mouse estrous cycle
(A) The estrous cycle is divided into four stages in mice: proestrus, estrus, metestrus, and diestrus
