introduction: gonadotropin inhibitory hormone (gnih) has been known as a key inhibitor of the secretion of gonadotropin releasing hormone (gnrh). ewe has estrous cycles comprising of follicular and luteal phases. follicular phase is in turn divided into proestrous and estrous phases. blood level of lh increases in follicular and decreases in luteal phases. the aim of the present study was to ev...

Although endogenous sex steroid hormones in premenopausal women may be associated with the risk of breast cancer and other illnesses, direct evidence to support this hypothesis is limited in large part by methodological issues in the conduct of relevant studies. One major unresolved issue is whether a single blood sample (such as is available in most epidemiological studies), collected in a spe...

conclusions the most comfortable postoperative women were those in luteal phase without history of pms group. results patients with pms presented higher pain sensation and analgesia request (p = 0.003). patients in luteal phase showed less pain and analgesia request in two out of five studied outcomes (p = 0.075). patients and methods a total of 140 women in in postoperative period were assigne...

An experiment was conducted to investigate the effect of different types of ovarian cycles on reproductive indices and blood metabolites in 61 Holstein cows. Blood samples were taken from each cow between day 12 and day 50 postpartum (PP). Serum progesterone concentrations were measured to determine the onset of luteal function and different types of luteal dysfunctions in cows. Serum glucose, ...

OBJECTIVES (1) To describe the progesterone profiles following pituitary down regulation in stimulated IVF cycles with the use of GnRH-a (2) To assess the impact of progesterone supplement and pregnancy on the subsequent luteal phase. STUDY DESIGN A prospective observational study performed in a specialist infertility clinic based at a tertiary centre in the north of England. Subjects were di...

Objective: To assess the effect of GnRHa as luteal phase support in women undergoing controlled ovarian stimulation and IUI. Design: A prospective, randomized trial. Setting: Cytogenetic and Endoscopy Unit, Zagazig University Hospital. Methods: Two hundred fourteen women either with unexplained or mild male factor infertility was planned to contribute to this study. After exclusion 18 women, 19...

overall, 531 dairy cows were inseminated with the aim to study their reproductive performance following administration of gnrh analogue on different days of estrous cycle with different doses. these cows were divided into six treatment and one control group. depending upon different treatment groups, buserelin acetate was injected at a dose of 10.5 µg or 21.0 µg on different days (0, 5 or 12) o...

Kung et al authored a valuable article entitled “Luteal phase support with decapeptyl improves pregnancy outcomes in ICSI with basal FSH >8 mIU/mL or mature oocytes 3”. This retrospective study enrolled 240 patients who underwent intracytoplasmic sperm injection (ICSI). One hundred and forty-seven patients were in the decapeptyl group and 93 patients were in the control group. The authors inves...

Stimulated IVF cycles are associated with luteal phase defect. In order to overcome this, different doses, durations and types of luteal phase support (LPS) have been evaluated. There is still no agreement regarding the optimal supplementation scheme. The aim of this paper is to assess the past and the current clinical practices of luteal supplementation in IVF. The databases of Medline and Pub...
