Understanding the reproductive biology of giant pandas: predictive biomarkers for reproductive success
… period of true gestation. Giant pandas undergo pseudopregnancy, and currently there is no giant panda pregnancy test. The aim of this thesis is to non-invasively assess the reproductive profiles of a European-based cohort of giant pandas to determine if potential new reproductive biomarkers can …

Assessment of Physiological Challenges in Overwintering Black Bears (Ursus americanus): Active Gestation, Neonatal Growth, and Skeletal Muscle Conservation
… is conflicting evidence on the occurrence of ABB pseudopregnancy (a physiological state in which a non-pregnant bear exhibits progesterone levels similar to gravid bears in the absence of an actual pregnancy). Also, there is little known about postnatal development of cubs or the influence of …

Maintenance of pregnancy in goats: Relationships between the fetus, the corpora lutea and the concentrations of progesterone in the maternal plasma
… efficiency in goats is limited by spontaneous pseudopregnancy and abortion. These conditions are affected by the need for the corpus luteum (CL) to maintain progesterone throughout gestation. A study was done to understand the interrelationships of the CL, maintenance of pregnancy, the presence …

Prolactin signalling in murine hair growth
… across the body was slower during pregnancy and pseudopregnancy, and halted completely during lactation. Only after weaning was follicle reactivation resumed. As a key gestational and lactation hormone, prolactin is a likely candidate as a modulator of hair cycling at this time. An inverse …

Reproduction management in female Lynx (Lynx lynx)
… do not undergo regression after parturition or pseudopregnancy, as they do in other felids and most mammals. They continue the secretion of P4 and E2, which we could proof to be of luteal origin. Interestingly, each time E2 starts to increase (which indicates the onset of a new follicular …

Ecology and physiology of a black bear (Ursus americanus) population in the Great Dismal Swamp and reproduction physiology in the captive female black bear
… gestation also were profiled. The occurrence of pseudopregnancy or early embryonic mortality in bears with elevated serum progesterone concentrations is discussed.
