This is a prospective study to assess the psychiatric morbidity in Chinese infertile women who underwent treatments with assisted reproductive technology and also the impact of treatment failure. The 30-item General Health Questionnaire (GHQ) and the Beck Depression Inventory (BDI) were employed before and 3 weeks after the assisted reproductive technology(More)
OBJECTIVE To evaluate the effect of adjuvant low-dose aspirin on utero-ovarian blood flow and ovarian responsiveness in poor responders undergoing IVF. DESIGN Prospective randomized, double-blind, placebo-controlled study. SETTING University-affiliated teaching hospital. PATIENT(S) Sixty patients classified as poor responders undergoing IVF. (More)
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 cohort study. SETTING Assisted reproduction technology (ART) unit. PATIENT(S) Two hundred eighty-seven couples(More)
Only about 63% of Chinese women with polycystic ovarian syndrome (PCOS) as diagnosed by the 2003 Rotterdam criteria fulfilled the 1990 National Institutes of Health (NIH) diagnostic criteria. Although the NIH criteria are not generally applicable to the Chinese population, women fulfilling the NIH criteria have higher metabolic risk than those who do not(More)
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 from 22 women undergoing laparoscopic tubal sterilization or hysterectomy for a benign gynecological condition.(More)
STUDY OBJECTIVE To determine the frequency of intrauterine adhesions (IUA) after conservative management, medical evacuation, and surgical evacuation for spontaneous abortion. DESIGN Prospective follow-up study (Canadian Task Force classification II-2). SETTING Gynecology unit in a teaching hospital. PATIENTS Eighty-two women who had been treated with(More)
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 reaction analysis of oviductin mRNA expression after oviduct mucosal cell culture in the presence of 17beta E(2). Three(More)
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 ampullary regions of the human oviduct was isolated and cultured with (study groups) or without (control group) the addition(More)
OBJECTIVE To compare the mRNA expression of vascular endothelial growth factor (VEGF) and its receptors (KDR and flt-1) in the implantation and nonimplantation sites of the human oviduct with ectopic gestation. DESIGN Prospective observational study. SETTING University-based Obstetrics and Gynecology Department. PATIENT(S) Ten women undergoing(More)
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 ovulatory cycle. DESIGN Prospective observational study. SETTING University-based obstetrics and gynecology department.(More)
