BACKGROUND The need for effective parameters for selecting the best embryos is paramount when a large number of them are available for transfer. Other studies have reported that transfer of pre-selected embryos, based on cleavage to the 2-cell stage at 25 h and 27 h post-insemination/intracytoplasmic sperm injection (ICSI), increases implantation and pregnancy rates. We investigated whether ext...

background: In this 10th European IVF-monitoring (EIM) report, the results of assisted reproductive techniques from treatments initiated in Europe during 2006 are presented. Data were mainly collected from existing national registers. methods: From 32 countries, 998 clinics reported 458 759 treatment cycles including: IVF (117 318), ICSI (232 844), frozen embryo replacement (FER, 86 059), egg d...

A modified hypo-osmotic solution was used to select viable ejaculated and testicular spermatozoa to perform intracytoplasmic sperm injection (ICSI) in 27 treatment cycles from patients with total absence of sperm motility. The treatment cycles consisted of 15 cycles in which ejaculated spermatozoa were used and 12 cycles in which testicular spermatozoa were used. The hypo-osmotic solution consi...

BACKGROUND Anecdotal evidence suggests that US practice patterns for ART differ by geographical region. The purpose of this study was to determine whether use of ICSI differs by region and to evaluate whether these rates are correlated with differences in live birth rates. METHODS Public data for 2012 were obtained from the Centers for Disease Control and Prevention. Clinics with ≥100 fresh, ...

Purpose: To analyze whether the thyroid status is affecting in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes. Methods: In this retrospective cohort study, we reviewed the medical records of 426 infertile women who underwent IVF/ICSI cycles. Included were hypothyroid (HypoT-LT4) patients with serum thyroidstimulating hormone (TSH) concentrations > 4.0 μIU/mL, which wer...

BACKGROUND We performed this study to evaluate use of fresh and frozen sperm samples in non-obstructive azoospermia microdissection testicular sperm extraction (micro-TESE-ICSI) treatment. METHODS We performed a total of 82 consecutive in vitro fertilization (IVF) cycles at Fertijin IVF Center in Istanbul, Turkey from January 2010 to March 2012. In 43 participants we used fresh sperm and froz...

Purpose: to evaluate the effect of previous ovarian surgery for endometriosis on the ovarian response in assisted reproduction treatment cycles and its pregnancy outcome. Methods: a total of 61 women, with primary infertility and previous ovarian surgery for endometriosis, submitted to 74 in vitro fertilization/intracytoplasmic spermatozoid injection (IVF/ICSI) cycles, were studied (study group...

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:...
