Formation and maintenance of corpora lutea in laboratory animals.
T HE past decade has witnessed a revival of interest in the mammalian corpus luteum. The availability of new techniques is in part responsible but a more important factor has been the increasing use of cows, sheep, pigs and even women as experimental species. The use of these mammals has uncovered, to a much greater degree than was expected, a diversity in the physiology of the corpus luteum, a...

15 صفحه اولThe effect of the uterine cervical stimulation at postpartum estrus upon the post-weaning fate of the lactational corpora lutea.
Effects of the uterine cervical stimulation applied at the postpartum estrus was examined in the lactating rats whose pups were removed on various days from 0 to 26 day after parturition. The changes of vaginal smear and the secretion pattern of progestins were followed. In the animals either with (experimental group) or without (control group) the stimulation, the continuation of lactation bey...
متن کامل[Ovarian inhibin activity in rats with persistent estrus].
To investigate the significance of changes in ovarian inhibin in gonadal dysfunction with persistent estrus, female rats with persistent estrus were studied as animal model for polycystic ovaries (PCO). Newborn female Wistar rats treated with testosterone propionate s. c. (TP) and female rats raised under continuous light (LL) started at 9 weeks of age entered into continuous estrus 5 and 2 or ...
متن کاملPhysiologically Persistent Corpora lutea in Eurasian Lynx (Lynx lynx) – Longitudinal Ultrasound and Endocrine Examinations Intra-Vitam
Felids generally follow a poly-estrous reproductive strategy. Eurasian lynx (Lynx lynx) display a different pattern of reproductive cyclicity where physiologically persistent corpora lutea (CLs) induce a mono-estrous condition which results in highly seasonal reproduction. The present study was based around a sono-morphological and endocrine study of captive Eurasian lynx, and a control-study o...
