BACKGROUND Underweight and overweight may affect reproduction and interfere with treatment of infertility. The purpose of this report is to describe the independent effect of body weight on treatment with IVF and ICSI. METHODS Records of 5019 IVF or ICSI treatments in 2660 couples were reviewed. The influence of body mass index (BMI) on treatment outcome was examined, after accounting for dif...

background: in vitro fertilization (ivf) and intra cytoplasmic sperm injection (icsi) are recognized as established and increasingly successful forms of treatment for infertility, yet significant numbers of couples discontinue treatment without achieving a live birth. this study aims to identify major factors that influence the decision to discontinue ivf/icsi treatments. materials and methods:...

OBJECTIVE To evaluate the outcomes of patients with moderate oligoasthenozoospermia treated with conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). METHODS A total of 99 couples with moderate oligoasthenozoospermia undergoing their first IVF/ICSI cycle were included in the study. Sibling oocytes were randomized to be inseminated either by conventional IVF o...

OBJECTIVE To conduct a meta-analysis of studies assessing the effect of IVF and intracytoplasmic sperm injection (ICSI) on birth defects. DESIGN Meta-analysis. SETTING Centers for reproductive care. PATIENT(S) Patients treated by IVF and/or ICSI. INTERVENTION(S) We identified all studies published by September 2011 with data related to birth defects in children conceived by IVF and/or I...

This multicenter cohort study on embryo assessment and outcome data from 11,744 IVF/ICSI cycles with 104,830 oocytes and 42,074 embryos, presents the effect of women's age on oocyte, zygote, embryo morphology and cleavage parameters, as well as cycle outcome measures corrected for confounding factors as center, partner's age and referral diagnosis. Cycle outcome data confirmed the well-known ef...

BACKGROUND One of the recognized treatment options for patients with polycystic ovarian syndrome (PCOS) is in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). Fears are however sometimes raised concerning the likely outcome of treatment in such patients compared with their counterparts with tubal factor infertility. OBJECTIVE To compare the IVF/ICSI performance in women w...

In pigs, the embryonic developmental ability after intracytoplasmic sperm injection (ICSI) is inferior to that resulting from in vitro fertilization (IVF). We evaluated the timing of cell division up to blastocyst formation on embryonic development after ICSI using either whole sperm (w-ICSI) or the sperm head alone (h-ICSI) and IVF as a control. At 10 h after ICSI or IVF, we selected only zygo...

OBJECTIVE To investigate the oocyte quality in patients with severe ovarian hyperstimulation syndrome (OHSS). DESIGN Self-controlled clinical study. SETTING University teaching hospital. PATIENT(S) Twenty-two patients from our assisted reproductive technology (ART) program who developed severe OHSS during their first controlled ovarian hyperstimulation for IVF or intracytoplasmic sperm in...

With the introduction of intracytoplasmic sperm injection (ICSI), couples with severe male factor infertility have achieved fertilization and clinical pregnancy rates comparable to other in-vitro fertilization (IVF) patients. However, failure of fertilization still occurs in some patients despite the utilization of microsurgical sperm injection techniques. How such fertilization failure after I...
