BACKGROUND Determination of oocyte fertilization and embryo quality are one of the most important purposes in ART cycles. Follicular fluid provides an important microenvironment for development of oocytes and some biochemical characteristics of the follicular fluid, such as pregnancy-associated plasma protein-A (PAPP-A), may play an important role in prediction of success rate of ART. OBJECTI...
Anticoagulant heparan sulfate proteoglycans bind and activate antithrombin by virtue of a specific 3-O-sulfated pentasaccharide. They not only occur in the vascular wall but also in extravascular tissues, such as the ovary, where their functions remain unknown. The rupture of the ovarian follicle at ovulation is one of the most striking examples of tissue remodeling in adult mammals. It involve...
Background and purpose: Despite the rapid development of assisted reproduction techniques (ÂRT) in recent years, implantation rates after replacement of embryos into the uterine cavity remains low. Ân important approach to improve embryo quaility and implantation rates has been the use of coculture systems. Hence this study was undertaken to evaluate the influence of cumulus cells monolayer i...
SUMMARY Since at oocyte retrieval for in vitro fertilization there is some FF become incorporate to egg, we decided to investigate the effect of this fluid on preimplantation embryo development in vitro. FF was obtained at the time of oocyte retrieval for IVF, centrifuged and then either inactivated by heat and stored at 4°c or without inactivation stored at-20°c until used. Late 2-cell emb...
OBJECTIVE To identify aldosterone and precursors in ovarian follicles and to relate levels of mineralocorticoids to previously described renin-angiotensin system follicular fluid content. DESIGN Experimental. SETTING Academic laboratory and affiliated large private practice. PATIENT(S) Women undergoing oocyte retrieval for in vitro fertilization (IVF). MAIN OUTCOME MEASURE(S) The concen...
background: determination of oocyte and embryo quality are one of the most important goals in ivf. anti-mullerian hormone (amh) is secreted by the ovarian granulosa cells into blood flow and follicular fluid. follicular fluid anti-mullerian hormone level is probably a marker of activity of granulose cells. objective: to evaluate whether high level of follicular fluid anti-mullerian hormone leve...
Background: Induction of in vitro maturation and development of immature oocyte is one of the methods that has been frequently used recently in artificial reproduction techniques and has drawn attention of many investigators. This method is useful especially in women who are affected by cancer and polycystic ovary syndrome. Despite using many types of in vitro media, an appropriate environment ...
