Labib F., E. A. El Azab, F. A. Soliman: Hormonal Changes During Formation and Involution of Corpus Luteum in Rabbits. Acta vet. Brno, 47, 1978: 23-31. A study was made on 30 female Boscat rabbits to reveal the hormonal changes, namely, TSH, FSH, LH and L TH during the formation, maintenance and involution of the corpora lutea. Induction of ovulation was done by using gonadotrophic hormones (PMS...

The corpus luteum (CL) is a site of intense angiogenesis. Within a short period, this is followed either by controlled regression of the microvascular tree in the non-fertile cycle, or maintenance and stabilisation of the new vasculature a conceptual cycle. The molecular regulation of these diverse aspects is examined. The CL provides a unique model system in which to study the cellular and mol...

Corpus luteum (CL) is a small, transient endocrine gland formed following ovulation from the secretory cells of the ovarian follicles. The main function of CL is the production of progesterone, a hormone which regulates various reproductive functions. Progesterone plays a key role in the regulation of the length of estrous cycle and in the implantation of the blastocysts. Preovulatory surge of ...

Implantation is a complicated process that involves adequate preparation of the endometrium. An important contributor to this preparatory process is the corpus luteum, the primary function of which is to secrete progesterone to induce secretory transformation of the endometrium so that implantation can occur and the necessary support can be provided for the pregnancy during the early stages of ...

A 43-year old woman had recurrent massive intraperitoneal hemorrhage from rupture of a hemorrhagic corpus luteum in two successive menstrual cycles while receiving anticoagulant therapy. Left oophorectomy was performed on the first occasion and right salpingo-oophorectomy with left salpingectomy on the second. While the precise incidence cannot be determined, rupture from a hemorrhagic corpus l...

Binding of 125I-human chorionic gonadotropin (HCG) to homogenates of the human corpora lutea of the menstrual cycle and pregnancy was examined in vitro. While corpora lutea of the menstrual cycle bound 125I-HCG specifically, the corpora lutea of pregnancy from 8 weeks' gestation bound little or none of the added 125I-HCG. In the corpus luteum of the menstrual cycle the dissociation constant for...
