during assisted reproductive technology (art) procedures, the transfer of a single embryo dramatically reduces the rate of multiple pregnancy. proper information, therefore, should be delivered to patients before embryo transfer. in many countries, regulations limit, according to age of the patient, the number of embryos to be transferred. selective fetal reduction should not be considered as a...

OBJECTIVE The goal of this study was to investigate the relationship between serum progesterone (P4) levels on the day of human chorionic gonadotropin (hCG) administration and the pregnancy rate among women undergoing controlled ovarian stimulation for in vitro fertilization (IVF) or intracytoplasmic sperm injection-embryo transfer (ICSI-ET) using a flexible antagonist protocol. METHODS This ...

BACKGROUND In 2004, a law regulating assisted reproduction techniques (ART) was passed in Italy. The new rules allow for the formation and transfer of a maximum of three embryos at one time, whereas embryo selection and embryo storage are prohibited. The aim of this study is to evaluate the impact of these restrictions on ICSI outcome in couples affected by severe male factor infertility. MET...

BACKGROUND The reasons for increased birth defect prevalence following in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) are largely unknown. Classification of birth defects by pathology rather than organ system, and examination of the role of embryo freezing and thawing may provide clues to the mechanisms involved. This study aimed to investigate these two factors. MET...

Recent studies indicate a strong paternal influence on embryo development and progression of the embryo to the blastocyst stage. The aim of this study was to compare, during extended culture, the in-vitro development of embryos resulting from intracytoplasmic sperm injection (ICSI) of ejaculated spermatozoa (group 1, n = 347), epididymal (group 2, n = 22) or testicular (group 3, n = 18) spermat...

BACKGROUND Embryo selection is a vital part of in vitro fertilization (IVF) programs, with morphology-based grading systems having been widely used for decades. Time-lapse imaging combined with embryo morph kinetics may proffer a non-invasive means for improving embryo selection. We report the first ongoing and chemical pregnancies using Time-lapse embryo scope to select best embryos for transf...

BACKGROUND Different success rate of Intracytoplasmic Sperm injection (ICSI) has been observed in various causes of infertility. In this study, we evaluated the relation between ICSI outcome and different causes of infertility. We also aimed to examine parameters that might predict the pregnancy success rate following ICSI. MATERIALS AND METHODS This cross sectional study included1492 inferti...

To our knowledge, this is the first analysis in which male and female weights have been combined. The registry dataset covering a 12-year period was analysed for all treatment cycles where an embryo transfer was reported. In all, 706,360 cycles were analysed. Treatments include IVF, ICSI, IVF/ICSI and CPE. The highest success rate in IVF cycles was found in couples, with an obese male partner. ...

BACKGROUND Fertilization, cell division and embryo development depend on genomic contributions from male and female gametes. We hypothesize that teratozoospermic sperm influences early embryo development and embryo compaction. METHODS We conducted a retrospective analysis of embryos derived from intracytoplasmic sperm injection (ICSI) cycles. Two hundred thirty-five consecutive ICSI cycles we...

Background: Successful implantation requires presence of a good quality embryo and receptive endometrium. Endometrial receptivity is ability endometrium to successfully attach embryo, nourish keep it alive. Sonographic findings are weighed according uterine scoring system for reproduction (USSR) or biophysical profile (UBP) by Applebaum. It has become absolute necessity evaluate uterus prior tr...
