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 …

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.
