The present study was undertaken to evaluate the role of corpus luteum function in the implantation process of cryopreserved embryos. Six patients with tubal infertility were studied, with a total of 27 fresh embryos being replaced following controlled ovarian hyperstimulation and in vitro fertilization....

The immune system is essential for optimal function of the reproductive system. The corpus luteum (CL) is an endocrine organ that secretes progesterone, which is responsible for regulating the length of the estrous cycle, and for the establishment and maintenance of pregnancy in mammals. This paper...
Role of Tumor Necrosis Factor α and Its Type I Receptor in Luteal Regression: Induction of Programmed Cell Death in Bovine Corpus Luteum-Derived Endotheli... The role of tumor necrosis factor alpha (TNF alpha) and its type I receptor (TNFRI) in structural luteolysis was investigated. A semi...
Progesterone (P4) secretion by the corpus luteum is critical for the establishment and maintenance of pregnancy and plays a major role in regulating endometrial secretions essential for stimulating and mediating changes in conceptus growth and differentiation throughout early pregnancy. Numerous studies ...
IT has been postulated 1–3 that a waning corpus luteum in the presence of a developing follicle is necessary to produce strus in the ewe. One attempt to test this hypothesis by treating the anstrous ewe with 2–5 mgm. progesterone before gonadotrophin injection yielded negative results 1 . ...
In vivo levels of prostaglandin F2 alpha, E2 and prostacyclin in the corpus luteum of pregnant and pseudopregnant rats. Prostaglandin F2 alpha (PGF2 alpha) is a well-known luteolytic factor in the rat corpus luteum. To investigate a possible luteal origin of PGF2 alpha, meas... Olofsson,J...

Electrophoretic mobility shift analysis (EMSA) using nuclear proteins from bovine corpus luteum and bovine adrenal as well as in vitro transcribed/translated SF-1/Ad4BP consistently showed that only the site at -1190 bound the transcription factor significantly. Very weak binding was detectable also ...
Because prolactin acts to maintain thecorpus luteumof theovary, which is the source of the femalesex hormoneprogesterone, it helps to sustain pregnancy. In addition, prolactin secretion increases progressively during pregnancy. The secretion of prolactin also can bestimulatedby high doses ofestrogens,...
