The mixed legacy of the rat estrous cycle

open access: yesBiology of Sex Differences, 2023
Background The rat estrous cycle first characterized by Long and Evans in 1922 profoundly affected the course of endocrine research. Investigators took advantage of sex steroid hormone fluctuations associated with the cycle to assess hormonal influences ...

Why the estrous cycle matters for neuroscience

open access: yesBiology of Sex Differences, 2022
Background 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 ...

Mouse serum facilitates the expansion of the follicular cavity regardless of the estrous cycle phase [PDF]

open access: yesJournal of Ovarian Research
Objective In investigating the effect of alcohol intake on the in vitro development of preantral follicles, physiological differences across estrous cycle phases in mice probably affect the results; therefore, it is necessary to determine whether serum ...

Validation of a mathematical model of the bovine estrous cycle for cows with different estrous cycle characteristics

open access: yesAnimal, 2017
A recently developed mechanistic mathematical model of the bovine estrous cycle was parameterized to fit empirical data sets collected during one estrous cycle of 31 individual cows, with the main objective to further validate the model.

Behaviors Related to Psychiatric Disorders and Pain Perception in C57BL/6J Mice During Different Phases of Estrous Cycle

open access: yesFrontiers in Neuroscience, 2021
Robust sex difference among humans regarding psychiatry- and pain-related behaviors is being researched; however, the use of female mice in preclinical research is relatively rare due to an unchecked potential behavioral variation over the estrous cycle.

Gonadal steroids and leptin dynamics during estrous cycle of ewe: a correlative study [PDF]

open access: yesVeterinary Medical Journal - Giza, 2016
Leptin, as a hormone, acts as a signal for the energy status and affects reproductive performance. The current study investigated dynamics of gonadal steroids and leptin during estrous cycle in ewe.

The impact of the ovarian cycle on anxiety, allopregnanolone, and corticotropin releasing hormone changes after motherhood in female rats and women

open access: yesTranslational Psychiatry, 2023
Fluctuations in ovarian steroids across the estrous and menstrual cycle in female rats and women, respectively, are associated with changes in anxiety. Pregnancy causes long-term changes to ovarian hormone release, yet research on estrous- and menstrual ...
