OBJECTIVE To investigate the cognitive functioning of low-risk singletons born after intracytoplasmic sperm injection (ICSI) or in vitro fertilization (IVF) at the age of 5 or 10 years. METHODS Sixty-nine children (35 ICSI, 34 IVF) participated voluntarily in the study that had been approved by the local IRB. Their intellectual functioning was examined by the Kaufmann Assessment Battery for C...

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...

Over the years, IVF/ICSI protocols have continued to evolve with efforts to improve outcomes. As a result, treatment success may be related to certain procedural factors, including number of embryos transferred and stage at which they are transferred. This review aims to assess the safety and effectiveness of IVF/ICSI in comparison to spontaneous conception and less invasive ARTs and the impact...

OBJECTIVE The aim of this study was to explore the effects of the insemination method on the outcomes of elective blastocyst culture. METHODS We retrospectively analyzed the outcomes of elective blastocyst culture performed between January 2011 and December 2014. RESULTS There were 2,003 cycles of conventional in vitro fertilization (IVF) and 336 cycles of intracytoplasmic sperm injection (...

BACKGROUND More couples are delaying childbirth resulting in an increase of age-related subfertility in women. Subfertility and assisted reproductive technology (ART) treatments may affect couples' psychological well-being. The aim of the present study was to investigate whether factors related to IVF/ICSI affect anxiety and mental health in couples 1 year after childbirth. METHOD In this coh...

The invention of intracytoplasmic sperm injection (ICSI) has possibly been the most important development in reproductive medicine, one that has given hope to thousands of infertile couples worldwide. However, concerns remain regarding the safety of this method since it is a more invasive procedure than in vitro fertilization (IVF), since a spermatozoon is injected into the oocyte cytoplasm. Us...

The objective of this study was to evaluate the effect of electrical stimulation (EST) on pronuclear formation, chromosomal constitution, and developmental capability among in vitro matured pig oocytes following intracytoplasmic sperm injection (ICSI). After ICSI, the oocytes were randomly distributed and cultured into 3 groups: the EST activated ICSI group, non-activation ICSI group, and in vi...

An ultrasonographic evaluation of the endometrium was performed in 158 patients undergoing ovarian stimulation for an in-vitro assisted reproduction programme. Endometrial thickness was evaluated in 109 patients undergoing in-vitro fertilization (IVF) for female indications and in 49 patients undergoing intracytoplasmic sperm injection (ICSI) for male indications. The maximal endometrial thickn...

Objective: To investigate the effect of sperm DNA fragmentation index (DFI) on the clinical outcomes of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Methods: Infertile couples were prospectively recruited in the Reproductive Center in Jiaozuo Maternal and Child Care Service Centre in Henan, China, from July 2015 to December 2016. All the recruited 228 infertile coup...

BACKGROUND The latest studies reported that local endometrial injury is a useful method to improve the success of IVF-ICSI outcome. OBJECTIVE To assess whether local endometrial injury occurred by Pipelle in the spontaneous cycle could improve implantation rate, cleavage rate, and pregnancy outcome in the subsequent IVF-ICSI cycle in patients who had recurrent IVF failure. MATERIALS AND MET...
