TLDR
An important consideration in the examination of the female reproductive tract is that its condition is very dependent on the stage of reproductive function (estrous cycle, pregnancy, parturition, postpartum period).Abstract:
An important consideration in the examination of the female reproductive tract is that its condition, as well as the animal’s behavior, is very dependent on the stage of reproductive function (estrous cycle, pregnancy, parturition, postpartum period). Also, considerable change may have been brought about by ovariohysterectomyread more

Mammary gland neoplasia in long-term rodent studies
Irma H. Russo,Jose Russo +1 more
TL;DR: Until there is enough information on the predictive value of mechanism-based toxicology for risk assessment, this approach should be used in conjunction with and validated by the traditional in vivo long-term bioassays, combined with comparative in vitro systems.

Medfly areawide sterile insect technique programmes for prevention, suppression or eradication: the importance of mating behavior studies
TL;DR: There is considerable scope for improving the efficiency of medfly SIT, an indispensable requirement for increased involvement of the private sector in any future application.

3.9 – Hormonal Control of Reproductive Processes
TL;DR: In this paper, the authors proposed a 3.9.3.3-approximation algorithm for each node. And they evaluated it on 3.5.3 nodes.

Sperm competition as a mechanism of female choice in the field cricket, Gryllus bimaculatus
TL;DR: Female G. bimaculatus may control the degree of sperm competition as a mechanism of mate choice by accepting large quantities of sperm from chosen males and determining the paternity of their offspring by diluting out the sperm stored from previous matings.

Uterine glands: development, function and experimental model systems
TL;DR: The ability of neonatal progestin treatment in sheep and mice to produce infertility suggests that an approach of this kind may provide a contraceptive strategy with application in other species, and work is underway to determine whether neonatal PROGestin or other steroid hormone treatments might be a viable contraceptive approach in this species.

The Ovarian Cycle of the Bitch: Plasma Estrogen, LH and Progesterone
TL;DR: The results suggest that plasma estrogen initiates or potentiates the preovulatory release of progesterone may encourage the LH peak surge and the onset of behavioral estrus and that mechanisms exist that maintain elevated levels of plasma progestersone throughout pregnancy.
Journal ArticleDOI
Concentrations of reproductive hormones in canine serum throughout late anestrus, proestrus and estrus.
TL;DR: The results of the current investigation suggest that neither the canine ovary nor pituitary are quiescent during anestrus and the bitch appears to have sufficient FSH present during ananestrus for follicular growth.

The normal endoscopic appearance of the caudal reproductive tract of the cyclic and non‐cyclic bitch: post‐uterine endoscopy
TL;DR: The results obtained indicate that post-uterine endoscopy is a relatively rapid and accurate method of detecting the sexual status of the bitch, and compared well with the other methods used in this study.

Seasonal incidence of estrus and interestrous interval for bitches of seven breeds.
TL;DR: For 7 breeds of bitches (Toy Poodle, Cocker Spaniel, Basset Hound, Boston Terrier, German Shepherd Dog, Pekingese, and Beagle), estrous activity occurred in all seasons.
