OBJECTIVE To compare the effectiveness of elective single embryo transfer versus double embryo transfer on the outcomes of live birth, multiple live birth, miscarriage, preterm birth, term singleton birth, and low birth weight after fresh embryo transfer, and on the outcomes of cumulative live birth and multiple live birth after fresh and frozen embryo transfers. DESIGN One stage meta-analysi...
BACKGROUND There are different methods in endometrial preparation for frozen-thawed embryo transfer (FET). OBJECTIVE The purpose of this study was to compare the live birth rate in the artificial FET protocol (estradiol/ progesterone with GnRH-agonist) with stimulated cycle FET protocol (letrozole plus HMG). MATERIALS AND METHODS This randomized clinical trial included 100 women (18-42 year...
Metformin alone compared with placebo increases the ovulation rate in women with polycystic ovary syndrome (PCOS) but should not be used as first-line therapy for anovulation because oral ovulation induction agents such as clomiphene citrate or letrozole alone are much more effective in increasing ovulation, pregnancy, and live-birth rates in women with PCOS. There is fair evidence that metform...
BACKGROUND Pregnancy rates in women of advanced maternal age undergoing in vitro fertilization (IVF) are disappointingly low. It has been suggested that the use of preimplantation genetic screening of cleavage-stage embryos for aneuploidies may improve the effectiveness of IVF in these women. METHODS We conducted a multicenter, randomized, double-blind, controlled trial comparing three cycles...
OBJECTIVE To describe pregnancy outcomes among HIV-infected women and examine factors associated with live birth among those receiving and not receiving combination antiretroviral therapy (cART). METHODS The present analysis included women with HIV from Uganda and Zimbabwe who participated in a prospective cohort study during 2001-2009. Incident pregnancies and pregnancy outcomes were recorde...
Background: This study have conducted in order to determine of direct or indirect effective factors on mortality of neonates with low birth weight by path analysis.Methods: In this cohort study 445 paired mothers and their neonates were participated in Tehran city. The data were gathered through an answer sheet contain mother age, gestational age, apgar score, pregnancy induced hypertension (PI...
Rather than investigate whether paternal leukocyte immunization improves the live birth rate in women with three or more abortions, we analysed the results of patients expected to have a poor outcome in a subsequent pregnancy if untreated, i.e. women with five or more abortions and no anti-paternal complement-dependent antibody (APCA) at initial testing. The analysis included the results of pat...
Sperm DNA damage has a negative impact on pregnancy rates following assisted reproduction treatment (ART). The aim of the present study was to examine the relationship between sperm DNA fragmentation and live-birth rates after IVF and intracytoplasmic sperm injection (ICSI). The alkaline Comet assay was employed to measure sperm DNA fragmentation in native semen and in spermatozoa following den...
Approximately 14,000 women of reproductive age are currently living in the United States after liver transplantation (LT), and another 500 undergo LT each year. Although LT improves reproductive function in women with advanced liver disease, the associated pregnancy outcomes and maternal-fetal risks have not been quantified in a broad manner. To obtain more generalizable inferences, we performe...
Background The effect of elevated progesterone level on human chorionic gonadotropin (HCG) day in in vitro fertilization cycles is controversial. Some suppose that rise in progesterone level seems to have a negative impact on implantation and pregnancy by desynchronizing the endometrium, while others disagree. Objective To evaluate the superiority of the frozen cycle over fresh cycle on live ...
