Evaluation of anti-Mullerian hormone, antral follicle count and progesterone concentration during estrous cycle in Murrah buffaloes

Indian Journal of Animal Sciences, 2019
An experiment was conducted to study the anti-Mullerian hormone (AMH) concentration, antral follicle count (AFC) and progesterone (P4) concentration during estrous cycle in Murrah buffaloes. Seven animals of 5–10 years were selected for the study.

Chronic Stress Detrimentally Affects In Vivo Maturation in Rat Oocytes and Oocyte Viability at All Phases of the Estrous Cycle

Animals, 2021
Background: Stress has been considered as one of the causes of decreased reproductive function in women. However, direct evidence of the effect of chronic stress on oocytes depending on estrous cycle phases is limited.

Enhanced at puberty 1 (EAP1) is a new transcriptional regulator of the female neuroendocrine reproductive axis [PDF]

, 2007
The initiation of mammalian puberty and the maintenance of female reproductive cycles are events controlled by hypothalamic neurons that secrete the decapeptide gonadotropin-releasing hormone (GnRH).

A preclinical mouse model mimicking the ovarian cancer‐induced estrogen deficiency‐depression axis

Animal Models and Experimental Medicine, EarlyView.
A preclinical mouse model of ovarian cancer–related depression was developed by combining intraperitoneal tumor cell injection, ovariectomy, and chronic restraint stress. The model replicates key clinical features including estrogen deficiency, depressive‐like behaviors, and tumor progression, and provides a reliable tool for studying the endocrine ...

Changes in serum concentration of 17 beta-estradiol in female rats during estrous cycle after treatment with atrazine and zearalenone

Veterinární Medicína, 2001
A daily dose of 14 mg atrazine and 2.5 mg zearalenone, given p.o. during 5 days of estrous cycle to female rats, changed their estrous cycle in comparison with control animals.

Plasticity of intrinsic excitability across the estrous cycle in hypothalamic CRH neurons

Scientific Reports, 2021
Stress responses are highly plastic and vary across physiological states. The female estrous cycle is associated with a number of physiological changes including changes in stress responses, however, the mechanisms driving these changes are poorly ...

Sex as a biological variable in nonclinical studies: Bridging scientific rigor, animal welfare, and regulatory expectations

Animal Models and Experimental Medicine, EarlyView.
Sex as a biological variable (SABV) is a critical determinant of pharmacokinetics, pharmacodynamics, and toxicity in nonclinical studies. This review highlights how inappropriate neglect of sex differences compromises animal welfare, scientific reproducibility, and regulatory compliance.
