چکیده
Concentrations of estradiol and progesterone in blood collected during the 12.5-day gestation period of the Virginia opossum were not significantly different from those during equivalent days of the estrous cycle. Progesterone was correlated with an index of corpora luteral mass. Ratio of estradiol to progesterone were highest 3 to 4 days before estrus and on the day of parturition.

بررسی نسبت استرادیول به پروژسترون روز انتقال جنین و تاثیر آن روی نتایج تزریق داخل سیتوپلاسمی اسپرم
Background : One of the important problems in fertilization in vitro (IVF) is failure of implantation. This could be the result of estrogen and progesterone effects in endometrial acceptance during ovulation stimulation. Although progesterone has a vital role in primary phase of pregnancy, but the estradiol role in luteal phase is unknown. The aim of this study is assessment of the ratio of est...
متن کاملEffect of Ovarian Induction Using PMSG and HCG hormones on Uterus Dendritic Cells Population in NMRI mice
Introduction: Ovarian hyper-stimulation is widely used in IVF clinics. The main purpose of this method is to stimulate folliculogenesis and increase the number of oocytes in one cycle. Following ovarian hyper-stimulation, hormonal secretion of the ovary, particularly estradiol and progesterone dramatically increases. Immune cells especially dendritic cells have receptors for the estradiol...

Background: Implantation is characterized by the interaction of two immunologically and genetically distinct tissues. The embryo differs from the cells of the mother, and would be rejected as a parasite by the immune system of the mother if it didn’t secrete immunosuppressive agents. Thus, immunological rejection of the fetus due to recognition of paternal antigens by the maternal immune system...

Introduction: Implantation is one of the most important steps in ART cycles and it depends upon embryo and endometrial reception. Different protocols have been suggested for getting better endometrium. It seems estrogen increases the endometrial reception and pregnancy rate by inducing changes in the hormonal status. The aim of this study was to evaluate the effect of estradiol(E2) on luteal p...
متن کاملEffect of soy isoflavones on implantation losses in Wistar rat: implication of progesterone receptors, vascular endothelial growth factor and estradiol receptors alpha
Background: Implantation is a crucial period determining the success of a full pregnancy. Endocrine disruptors such as phytoestrogens (PEs) were thought to adversely influence embryonic implantations. However, the mechanism by which they upset implantation was not fully elucidated. Aims: The effect of administering soy isoflavones on the implantation of Wistar ...
