Abstract It is estimated that 17.3% of all pregnancies in the horse are lost from time detection to day 40, which has significant economic impact. But still, equine reproductive research limited funding opportunities. Understanding dynamics between embryo, endometrium, and corpus luteum (CL) essential ameliorate those losses. Pig embryonic interferon (IFN) gamma for establishment pregnancy. In ...

53 patients with Luteal phase defect (LPD) were treated with different Chinese medicinal herbs at different phases of menstrual cycle. On the 5th day of the menstrual cycle, the treatment was implemented with the rationale of "nourishing the Kidney Yin, invigorating the Spleen and replenishing the Qi, promoting the blood circulation and enriching the Blood" which might promote follicular develo...

The corpus luteum (CL) undergoes drastic changes in its function and structure during the estrous cycle. To secrete a sufficient amount of progesterone (P4) to ensure the occurrence of pregnancy in a cow with a body weight greater than 500 kg, the bovine CL weighs 5-8 g which is 2-3 thousand times heavier than rat CL. If pregnancy does not occur successfully, rapid luteolysis is caused by prost...

The present study sought to assess whether the receptors for adrenocorticotropic hormone (ACTH), MC2R, and for glucocorticoid (GR) are expressed in corpora lutea (CL) of pseudopregnant rabbits and whether ACTH and cortisol exert any direct action on luteal function. By immunohistochemistry, positive reaction for MC2R and GR was detectable within luteal cells of CL. The MC2R mRNA levels were fiv...

BACKGROUND Bovine luteal parenchymal cells express class II major histocompatibility complex (MHC) molecules and stimulate class II MHC-dependent activation of T cells in vitro. The ability of a class II MHC-expressing cell type to elicit a response from T cells in vivo is also dependent on expression of costimulatory molecules by the antigen presenting cell and delivery of a costimulatory sign...

In the female reproductive system, as in a few adult tissues, angiogenesis occurs as a normal process and is essential for normal tissue growth and development. In the ovary, new blood vessel formation facilitates oxygen, nutrients, and hormone substrate delivery, and also secures transfer of different hormones to targeted cells. Ovarian follicle and the corpus luteum (CL) have been shown to pr...

BACKGROUND Menstrual cycle-related symptoms are an important health issue for many women, and some may affect cardiac autonomic regulation. In the present study, we evaluated the cardiovascular and physiological stress response to 12-h short-term fasting in the menstrual phases of healthy young women. METHODS We performed a randomized crossover study. Subjects were seven female university stu...

A bstract. The pattern of episodic gonadotropin release was studied in 15 normal female volunteers during the luteal phase ofthe menstrual cycle with 24 h ofblood sampling for follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels at 10-min intervals. Six subjects (two in the early, two in the mid-, and two in the late luteal phase) also had each of these specimens processed for...
