Mouse Estrous Cycle Identification Tool and Images
PLoS ONE, 2012 The efficiency of producing timed pregnant or pseudopregnant mice can be increased by identifying those in proestrus or estrus. Visual observation of the vagina is the quickest method, requires no special equipment, and is best used when only proestrus ...

The estrous cycle in the dog: A review
Theriogenology, 1977Abstract Clinical, morphologic and hormonal changes throughout the estrous cycle in the dog are discussed in relation to the well established stages in this species — proestrus, estrus, metestrus and anestrus. Although most efforts in the past have been devoted to the period of reproduction, events throughout the remaining months of the cycle are ...

Apoptosis in the Estrous and Menstrual Cycles
Journal of Mammary Gland Biology and Neoplasia, 1999In the absence of pregnancy, the adult mammary gland is subjected to cyclic fluctuations of hormonal stimulation that constitute the estrous and menstrual cycles. The mammary epithelium responds to these systemic hormonal changes by regional proliferation, differentiation and cell death by apoptosis.

Estrous Cycle Manipulation in Dogs
Veterinary Clinics of North America: Small Animal Practice, 2018Since 1939, scientists have studied estrous cycle manipulation in dogs resulting in more articles published in this field that any other area of canine reproduction. Estrous cycle manipulation in dogs must be safe and reliable. Dopamine agonists, gonadotropin-releasing hormone agonists, and gonadotropins are hormones that have been used for estrus ...
