The ICSI has become method of choice to achieve fertilization. Fertilization is possible in cases in which the sperm motility and ability to penetrate the zona pellucida are impaired. Injection is possible with sperm obtained from ejaculation, microsurgical epididymal sperm aspiration (MESA), percutaneous epididymal sperm aspiration (PESA), or testicular sperm extraction (TESE). In addition, in...

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, ...

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...

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...

Assisted reproduction with testicular sperm extraction (TESE) and intra-cytoplasmic sperm injection (ICSI) are fertility treatment options for couples with severe oligospermia or azoospermia. A retrospective review was performed of 146 TESE procedures in a specialist fertility centre in Ireland. The indication for TESE was obstructive azoospermia (OA) in 59% (n = 80) and non-obstructive azoospe...

European results of assisted reproductive techniques from treatments initiated during 1999, are presented in this third report. Data were collected mainly from pre-existing national registers. From 22 countries 538 clinics reported 258 460 cycles: IVF 125 370, ICSI 95 221, frozen embryo replacement (FER) 34 002 and oocyte donations (OD) 3867. In eight countries, where all clinics reported to th...

BACKGROUND We evaluated the impact of using ICSI for assisted fertilization on first trimester survival rates of singleton gestations among an unselected infertile population. METHODS The 1244 singleton gestations achieved by ICSI were segregated according to underlying infertility aetiology, with 55.0% having male factor, 3.6% endometriosis, 4.3% polycystic ovarian disease, 9.1% tubal factor...

The aim of this prospective follow-up study of children born after intracytoplasmic sperm injection (ICSI) was to compile data on karyotypes, congenital malformations, growth parameters and developmental milestones in order to evaluate the safety of this new technique. The study design included karyotyping of the parents and their agreement to genetic counselling and prenatal diagnosis and it w...

OBJECTIVE To evaluate marker distribution of free beta-human chorionic gonadotrophin (fbeta-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in singleton pregnancies conceived by assisted reproduction techniques (ART). METHODS In vitro fertilization (IVF) (n = 203) and intracytoplasmic sperm injection (ICSI) (n = 192) cases from a database of 14 645 first-trimester combined tests (over...

OBJECTIVE To develop a microfluidic device that can reduce the intracytoplasmic sperm injection (ICSI) treatment time by increasing sperm concentration. DESIGN We compared the ICSI treatment time required for porcine sperm using a method employing the microfluidic device and one using the conventional microdroplet method. SETTINGS Academic research laboratories at Okayama University. ANIM...
