BACKGROUND In this study, we aimed to investigate the ability of transvaginal Doppler ultrasonography in predicting in vitro fertilization (IVF) outcome in women undergoing this procedure. MATERIALS AND METHODS In this prospective observational study, 65 infertile women underwent IVF procedure in Isfahan, during 2013-2014, were studied. The pulsatility index (PI), resistive index (RI) and pea...

background: implantation remains a limiting step in ivf/icsi. endometrial injury isa promising procedure aiming at improving the implantation and pregnancy rates after ivf/icsi. objective: the aim of this study was to evaluate the effect of endometrial injury induced in precedingcycle on ivf/icsi outcome. materials and methods: four hundred patients undergoing their first ivf/icsi cycle in two ...

OBJECTIVE To determine the effect of luteal-phase acupuncture on the outcome of IVF/intracytoplasmic sperm injection (ICSI). DESIGN Randomized, prospective, controlled clinical study. SETTING University IVF center. PATIENT(S) Two hundred twenty-five infertile patients undergoing IVF/ICSI. INTERVENTION(S) In group I, 116 patients received luteal-phase acupuncture according to the princip...

During the last decades, many studies have shown the possible influence of sperm DNA fragmentation on assisted reproductive technique outcomes. However, little is known about the impact of sperm DNA fragmentation on the clinical outcome of frozen-thawed embryo transfer (FET) from cycles of conventional in vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI). In the present stu...

OBJECTIVE To determine if there is an association between first IVF cycle outcome and subsequent delivery rate for women over 40 years. DESIGN Retrospective data analysis. SETTING Large, private academically affiliated IVF center. INTERVENTION(S) Patients over 40 years of age undergoing IVF. MAIN OUTCOME MEASURE(S) Delivery rate compared between patients with a pregnancy loss versus a n...

PROBLEM The effect of mini-dose heparin/aspirin (H/A) alone vs. combined intravenous immunoglobulin G (IVIg) and H/A on in vitro fertilization (IVF) birthrates in women who test seropositive for antiphospholipid antibodies (APA+) was evaluated, as was the question of whether outcome is influenced by the gammaglobulin isotype(s) or the phospholipid (PL) epitope(s) to which the APAs are directed....

BACKGROUND Several studies have investigated seasonal variations during IVF. Their results are contradictory, especially concerning fertilization and pregnancy rates. The aim of the present study was to re-evaluate these parameters using a large number of IVF cycles. METHODS A total of 7368 IVF cycles conducted in Switzerland between 1995 and 2003 were retrospectively analysed. To avoid a bia...

A published review of the literature by Dutch investigators in 2004 suggested significant outcome differences between spontaneously - and in vitro fertilization (IVF) - conceived singleton and twin pregnancies. Here we review whether later studies between 2004-2015 confirmed these findings. Though methodologies of here reviewed studies varied, and all were retrospective, they overall confirmed ...

In singleton pregnancies after in-vitro fertilization (IVF), increased rates of obstetric and perinatal complications have been reported. Studies that compared IVF twin pregnancies with spontaneously conceived twins have yielded conflicting results. We compared 96 IVF twin pregnancies to 96 controls after elaborate matching. The design of our study precluded matching by zygosity. The monozygosi...
