Behavioral and Reproductive Aspects of Captive Maxwell's Duiker (<em>Cephalophus mawellii</em>) Husbandry
… the effects of housing on activity budgets and progesterone cycling. Four animals were studied across two housing situations: housed individually versus housed in a grouped setting. Behavioral observations revealed no significant change in access to resources, rumination, or repetitive …

Thermoregulation, hibernation and reproduction in the South African hedgehog Erinaceus frontalis A. Smith
… changes in plasma testosterone and plasma progesterone levels during a one year period were determined. From September to January the arculating levels of testosterone were high while low levels were recorded from February to June. Testicular activity resumed at the end of winter when the …

The impact of variation in the progesterone receptor gene, life history and lifestyle on endometrial function and the menstrual cycle
… by the available data. A polymorphism in the progesterone receptor gene, called PROGINS, shows diminished progesterone response in vitro and is associated with a number of uterine disorders in women. To elucidate the discrepancy between ovarian and uterine markers of fecundity, carriers of the …

Progesterone and Prolactin Profiles of the Female Asian Elephant (Elephas Maximus)
Serum progesterone and prolactin concentrations were determined daily (around estrus), weekly (throughout the estrous cycle), and bimonthly (during gestation) in 8 female Asian elephants. A total of 18 estrous cycles with 4 resulting in conception are described. Early gestational values are shown …

Activation of the corticolimbic brain by visual food cues; Effect of menstrual cycle phase and mood
… the menstrual cycle. Changes in estrogen and progesterone levels during the menstrual cycle induce changes in appetite and eating behavior. Food intake declines in the peri-ovulatory period when estrogen levels peak, but increases in the luteal phase when progesterone levels increase. In this …

Comparison of pregnancy rates, progesterone concentrations, and expression of genes associated with progesterone synthesis in heifers and mature cows
… decline in mature cows could be impaired progesterone production. Therefore relationships of parity with reproductive performance, its effect on progesterone concentrations and genes associated with progesterone synthesis were examined in this thesis. In the first experiment, breeding …

THE EFFECT OF HOLDING TIME OF WHOLE MARE BLOOD ON CONCENTRATION OF PROGESTERONE
… holding time had an effect on mare whole blood progesterone levels. This research was completed using 12 mares, with blood being collected on multiple cycles to get a total of 28 separate blood collections. At each collection 5 vials of blood were taken for different time treatments of 0, 12, …

Investigation of the role of smooth muscle function in egg transport in the mouse oviduct.
… the oviduct on egg transport and oviduct calcium levels. The results indicate that the concentration of calcium could play an important role in the regulation of oviduct contractility and egg transport. A definite pattern of calcium ion concentration changes occurred during normal egg transport, …

A study of the factors controlling embryo transport in the oviduct of the mouse.
… of tubal transport which can be reversed by progesterone administration and measurement of serum progesterone levels indicates that progestogenic activity is required for normal tubal transport. Administration of testosterone also caused delay which could be reversed by progesterone …

Menstrual cycle dysfunction and weight loss practices among college-age women
… blood samples were assayed for estradiol and progesterone for one menstrual cycle. Mean age, number of years dieting, and BMI were similar between subjects. Five subjects (36%) had progesterone levels indicative of luteal phase deficiency or anovulation. The EAT-26 score was not associated …

Determination of an Estrous Cycle in Female Giraffes (Giraffa Camelopardalis) By Radioimmunoassay of Fecal Hormones
… ethyl acetate/hexane solution, concentrations of progesterone and estradiol were determined by radioimmunoassay. The average cycle length for each female was determined by their inter-progesterone peak duration. Averages ranged from 10 to 14 days. There was a trend for male interest/breeding to …

Reproductive Biology of the Bonnethead (Sphyrna tiburo) from the Southeastern U.S. Atlantic Coast
… increased during sperm storage, whereas progesterone levels increased near the end of this stage. Immunocytochemical analysis of androgen, estrogen, and progesterone receptors in the oviducal viii gland, the organ that stores sperm in female bonnetheads, demonstrated that epithelial cells …

The Role of EGFR Signaling in Gonadotropin-Induced Steroidogenesis
… the importance of EGFR signaling since serum progesterone levels were significantly reduced when EGFR was inhibited. These findings demonstrate physiologic importance and potential treatment options since women with endocrine disorder such as PCOS can be treated with EGFR antagonist to reduce …

Development of an image based technique for assessment of colorectal epithelial integrity and function in an ovine model
… to an ovine model in which estrogen and progesterone levels are altered. Past studies indicate that estrogen strengthens tight junctions and reduces permeability of the gut when present. This study finds that sheep that have been hormonally suppressed with depot medroxyprogesterone have a …

Priming with Oral Progestin Before Ovulation Induction Facilitates Ovarian Function in the Cat (Felis catus)
… endocrine data revealed that normal luteal progesterone levels were maintained only in queens primed with the oral progestin. Finally, histology and quantitative RT-PCR were used to characterize the differential effects on luteal function observed. Aberrant CL progesterone production was not …

A mixed methods examination of attitudes and perceived mood change and well-being across the menstrual cycle
… where testing should be carried out if differing levels of hormones were to be captured. Testing format used a three-phase approach which added a mid-luteal phase to the more typical menstrual and ovulatory phases. This was designed in order to capture the influence of a surge in progesterone …

Sex as a Biological Variable in Preclinical Animal Studies with an Infectious Disease Exemplar.
… expression associated with elevated estradiol levels. Vaginal microbiota composition remained stable across individuals, with increases in Mobiluncus spp. observed only during peak progesterone levels rather than throughout the secretory phase. This work establishes a framework for integrating …
