BACKGROUND An increased risk of major congenital abnormalities after IVF and ICSI has been described, but underlying mechanisms are unclear. This study evaluates the effects of ovarian hyperstimulation, the in vitro procedure and time to pregnancy (TTP) - as proxy for the severity of subfertility - on the prevalence of dysmorphic features. DESIGN/METHODS Participants were singletons born foll...

background: Several studies have examined the relationship between direct antisperm antibody (ASA) levels in semen and pregnancy rate after advanced assisted reproductive technologies (ARTs) but the results have been inconsistent. The aim of our study was to further evaluate the relationship between ASA and pregnancy after IVF or ICSI by systematic review and meta-analysis. methods: We conducte...

objective: recently the laparoscopic ovarian drilling (lod) has been used as a surgical treatment for ovulation in women with polycystic ovarian syndrome (pcos), although its mechanism and outcomes are still unclear. this study was undertaken to evaluate the in vitro fertilization (ivf)/intracytoplasmic sperm injection (icsi) outcomes in clomiphene-resistant women with pcos who were treated wit...

Background The aim of this study was to investigate the effect of body mass index (BMI) on the outcome of in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI) cycles in non polycystic ovary syndrome (PCOs) women. MaterialsAndMethods In this cross sectional study, 287 infertile non PCOs women referred to Royan institute, Tehran, Iran between 2002 and 2003 were enrolled. Patients...

Objective: In IVF-ICSI cycles with GnRH antagonist protocol, it was aimed to investigate the effects of hCG day hemogram values on OPU and success, implantation clinical pregnancy rates. Methods: Patients who underwent IVF-embryo transfer (ET) cycle after controlled ovarian stimulation (COS) ICSI treatment in a secondary care center between 2019 2020 were retrospectively screened. The differenc...

BACKGROUND The role of serum anti-Müllerian hormone (AMH) as predictor of in-vitro fertilization outcomes has been much debated. The aim of the present study is to investigate the practicability of combining serum AMH level with biological age as a simple screening method for counseling IVF candidates of advanced reproductive age with potential poor outcomes prior to treatment initiation. MET...

The purpose of this study was to determine whether dithiothreitol (DTT) treatment of sperm and ethanol activation improve embryo production by intracytoplasmic sperm injection (ICSI). Further, we compared ICSI with standard in vitro fertilization (IVF) in oocytes obtained from cattle. We demonstrated that DTT reduced the disulfide bond in the bovine sperm head. Using oocytes obtained from a sla...

Cycles with progesterone elevation during controlled ovarian stimulation (COS) for IVF/ICSI are commonly managed with a "freeze-all" strategy, due to a well-recognized detrimental effect of high progesterone levels on endometrial receptivity. However, also a detrimental effect of elevated progesterone on day-3 embryo quality has recently been found with regards to top quality embryo formation r...

Research question How do cumulative live birth rates (CLBR), multiple (CMLBR) and dropout over six IVF intracytoplasmic sperm injection (ICSI) cycles change time? Design Prospective longitudinal cohort (n = 16,073 patients; 48,946 cycles) starting a first fresh assisted reproductive technology cycle between 1 January 2014 31 December 2016, with follow-up until 2017. Outcomes the periods 2014–20...

STUDY QUESTION The 15th European IVF-monitoring (EIM) report presents the results of treatments involving assisted reproductive technology (ART) initiated in Europe during 2011: are there any changes in the trends compared with previous years? SUMMARY ANSWER Despite some fluctuations in the number of countries reporting data, while the overall number of ART cycles has continued to increase ye...
