In the corpus luteum of rats and mice, 20alpha-hydroxysteroid dehydrogenase (20alpha-HSD) catalyzes the conversion of progesterone to a biologically inactive metabolite, 20alpha-dihydroprogesterone (20alpha-OHP). The reduction of progesterone by 20alpha-HSD is believed to be important for functional luteolysis in these rodent species. In addition to the corpus luteum, expression of 20alpha-HSD ...

ABSTRACT: This review analyses the main factors of success of insemination as well as the methods suitable for oestrus induction in order to improve reproductive efficiency of rabbit does in term of fecundity (combining fertility and prolificacy). Parity, lactation status, pse...

1. The incorporation of [3H]uridine into RNA of rat uterine tissue has been measured during pseudopregnancy and in rats receiving different doses of an anti-implantation compound [tran8-1-(p-,B-dimethylaminoethoxyphenyl)-1,2diphenylbut-l-ene, I.C.I. 46474]. 2. In the uterus of the pseudopregnant rat uridine incorporation into RNA increased markedly on day 3 of pseudopregnancy, remained high unt...

introduction: the aim of this study was to evaluate the expression of pinopodes as animplantation marker after ovarian hyper stimulation and progesterone injection using scanningelectron microscopic studies. material and methods: three groups of nmri adult female mice were used in the experiment. the control group (group a) were untreated pseudopregnant mice. group b mice were made pseudopregna...
