OBJECTIVE: To examine the prevalence of hepatitis B virus (HBV) infection, the associated causes of subfertility, and the outcomes of the first IVF and embryo transfer treatment cycles in these infertile couples. DESIGN: A retrospective co…

OBJECTIVE: This investigation assessed the effect of serum estradiol levels on outcomes of in-vitro fertilization and embryo transfer (IVF) cycles. MATERIALS AND METHOD: This was a retrospective cohort study of 1123 IVF cycles comparing im…

PURPOSE: To evaluate the responses of cultured oviduct mucosal cells to exogenous estradiol treatment in regulating the mRNA expression of vascular endothelial growth factor (VEGF) and its receptors. METHODS: The mucosal layer of the ampul…

OBJECTIVE: To determine whether oviduct mucosal cell culture with exogenous 17beta E(2) supports the continued production of oviductin, a putative embryotrophic protein. DESIGN: Semiquantitative reverse-transcriptase polymerase chain react…

OBJECTIVE: To examine the localization of vascular endothelial growth factor receptors (VEGF-R) and the changes in VEGF-R messenger ribonucleic acid (mRNA) expression in various regions of the oviduct from fertile women throughout the ovula…

In this study, we examined the localization of vascular endothelial growth factor (VEGF) and the changes in VEGF mRNA expression in various regions of the oviduct in fertile women throughout the ovulatory cycle. Oviduct tissue was collected…
