The corpus luteum (CL) is a usually transient endocrine gland located on the mammalian ovary. The gland produces progesterone, which is the main hormone that prepares the uterus for embryo implantation and helps maintain pregnancy. In some species, other progestagen are produced (Brown2018; Conley...
The synthesis of progesterone by the corpus luteum is essential for the establishment and maintenance of early pregnancy. Regulation of luteal steroidogenesis can be broken down into three major events; luteinization (i.e., conversion of an ovulatory follicle), luteal regression, and pregnancy induced...
One strategy to improve P4 concentration is the administration of gonadotropin-releasing hormone (GnRH) or human chorionic gonadotropin (hCG), thereby inducing the formation of accessory corpus luteum (CL). This study aimed at determining the efficacy of GnRH or hCG treatment regarding embryo transfer...
The corpus luteum (CL) is a gland formed after ovulation with a temporary endocrine function. The main role of the CL is to secrete progesterone to maintain pregnancy. The CL can be divided into cyclical and pregnancy CLs. If pregnancy does not occur, the CL will degenerate into a white ...
