ndometrial vasculature has been shown to play an important role in the early endometrial response to the implanting blastocyst, and vascular changes may contribute to uterine receptivity . the aim of this study was to investigate the role of endometrial and subendometrial vascularity and thickness in uterine receptivity in infertile women treated with assisted reproductive technologies (art). a...
objective: to compare the effectiveness of letrozole and clomiphene citrate (cc) on uterine blood flow rate in patients with unexplained infertility. materials and methods: in this randomized clinical trial 90 women with unexplained infertility referred to a university clinic from january 2011- december 2013 were enrolled. thirty patients were randomized for letrozole, 30 patients for cc and 3o...
Background & Objectives: Recurrent miscarriage (RM) occurs in some women. There is much evidence that increased uterine blood flow resistance (reduced uterine perfusion) increases the risk of RM. This study was aimed at evaluating the efficacy of Omega 3-6-9 fatty acids, alone or in combination with aspirin, in the reduction of uterine blood flow resistance in women with a history of RM. Metho...
Experiments were carried out in pregnant nephrectomized rabbits to determine the relationship between uterine blood flow and uterine renin secretion. Uterine blood flow was measured by the percentage distribution of radioactive microspheres injected into the left ventricle which lodged in uterus and placenta, and cardiac output was measured by dye dilution. In 40 animals, 24 hr after nephrectom...
background: pregnancies with early onset fetal growth restriction have poor perinatal outcome. sildenafil citrate (pde -5 inhibitor) as a vasodilator increases uteroplacental blood flow and potentiates fetal growth. case presentation: in this study, a case was examined and sildenafil was administered for her. it was found that sildenafil improved the uterine blood flow with a favorable fetal ou...
Blood flow to each uterine horn of cows during the oestrous cycle and early pregnancy was determined daily by use of electromagnetic blood flow probes placed around both middle uterine arteries. The pattern of blood flow to uteri of pregnant and non-pregnant cows was similar until Day 14 after mating or oestrus. Between Days 14 and 18 of pregnancy blood flow to the uterine horn containing the c...
We studied the relationship of fetal and maternal vascular pressures to umbilical and uterine blood flow in the unanesthetized ewe and in the sheep fetus in utero by placing electromagnetic flow transducers around both the common umbilical and uterine arteries. Reductions in umbilical arterial pressure or elevations in umbilical venous pressure decreased umbilical blood flow without affecting e...
BACKGROUND Uterus transplantation may be the only theoretical option for some women, for example, those with congenital uterine infertility or who have undergone hysterectomy. In this study, we evaluated the intra- and post-operative blood flow conditions of vascular anastomosed regions and the blood-perfused area of the transplanted uterus in a cynomolgus macaque model of uterus autotransplant...
Total ovarian blood flow of cows (sum of flows through the ovarian artery and uterine branch of the ovarian artery), measured by electromagnetic flow probes, followed a consistent cyclic pattern, being highest from Day 10 of the oestrous cycle (oestrus = Day 0) until 4 days before the subsequent oestrus. During this period of high ovarian blood flow, blood of uterine origin flowed to the ovary ...
