The purpose of this study was to compare the psychological reactions of men undergoing intracytoplasmic sperm injection (ICSI) (n=18) or in-vitro fertilization (IVF) (n=22). Men monitored their psychological reactions daily for one complete treatment cycle from the first day of down-regulation until the outcome of treatment was known (approximately 52 days). The results showed that ICSI patient...

STUDY QUESTION Do young adolescents conceived by ICSI display a higher blood pressure than spontaneously conceived (SC) adolescents? SUMMARY ANSWER In our study, 14-year-old male and female ICSI teenagers were not found to have increased blood pressure at rest. WHAT IS KNOWN AND WHAT THIS PAPER ADDS Only limited data are available regarding the cardiovascular risk of children born after ass...

I n the recent literature, several interesting articles have been published using the zona pellucdia (ZP)-bound sperm for intracytoplasmic sperm injection (ICSI) to enhance embryo quality, implantation and clinical pregnancy rates. The three studies were performed independently in different ART clinics. In the test group, patients’ sibling immature (either germinal vesicle (GV) or metaphase I) ...

Intracytoplasmic sperm injection (ICSI) is the latest, and by far the most efficient, variant of micromanipulation-assisted fertilization, whereby a single spermatozoon is selected, aspirated into a microinjection needle and injected to the oocyte cytoplasm. The development of this technique is mainly linked to application in human assisted reproduction for which it enables fertilization with d...

Intracytoplasmic sperm injection (ICSI) is a powerful technique in the field of assisted reproduction (ART) and provides exciting opportunities for studying the basic mechanisms of fertilization and early embryo development. Nevertheless, its application in agriculture and conservation biology has been greatly hampered by the low success rate reported for this method in respect of economically ...

In pigs, the damaged sperm membrane leads to leakage of phospholipase C-ζ (PLCζ), which has been identified as a sperm factor, and a reduction of oocyte-activating ability. In this study, we investigated whether sperm selected by Percoll gradient centrifugation (Percoll) have sufficient PLCζ, and whether the efficiency of fertilization and blastocyst formation after intracytoplasmic sperm injec...

We report the successful outcome of intracytoplasmic sperm injection (ICSI) treatment in two siblings with familial globozoospermia. After controlled ovarian hyperstimulation and oocyte pick-up, retrieved oocytes were mechanically activated before ICSI and a fertilization rate of 33.3% was achieved in the first case. The second couple underwent ICSI without oocyte activation and a 9.1% fertiliz...

OBJECTIVE To assess the neurodevelopmental health of children born after intracytoplasmatic sperm injection (ICSI). DESIGN Prospective controlled blinded study. SETTING Tertiary care center. PATIENT(S) A total of 276 term-born singletons conceived by ICSI and 273 matched spontaneously conceived (SC) singletons at the age of 5.5 years. MAIN OUTCOME MEASURE(S) Neuromotor development asses...

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...

We determined the association of androgen receptor (AR) (CAG)n lengths among fertile and infertile males and offspring conceived by intracytoplasmic sperm injection (ICSI). Assessment of (CAG)n repeats in the AR was performed in a Caucasian population by gene sequencing in fertile men (n=13), infertile men (n=64), boys conceived after ICSI (n=21), and boys conceived naturally (n=11). In the AZF...
