Although around 1-4% of human zygotes have been found to be tripronuclear, there is little information about the subsequent development and chromosomal composition of embryos that derive from these zygotes. Herein, we report a pregnancy and subsequent delivery of a healthy newborn after the transfer of a blastocyst that developed from a tripronuclear zygote that had a euploid microarray result.

Morphologic abnormalities in the oocyte are relevant for determining its developmental fate and could be related to controlled ovarian stimulation protocols and ovarian response. The contributing factors of oocyte dysmorphism incidence and its effects on fertilization potential and embryo development are the object of discussion in this study.

OBJECTIVE To compare the karyotype of babies conceived through ICSI with that of naturally conceived babies. DESIGN Prospective controlled study. SETTING The Egyptian IVF-ET Center, Cairo, Egypt. PATIENT(S) Four hundred and thirty babies conceived through ICSI and 430 babies conceived naturally. INTERVENTION(S) ICSI and karyotyping. MAIN OUTCOME MEASURE(S) Abnormal karyotype. RESULT...

BACKGROUND Oocyte quality is a key limiting factor in female fertility which is primarily reflected in morphological features. Centrally located cytoplasm granulation (CLCG) is one type of cytoplasmic dimorphism exhibited by oocytes that could be linked to pesticide exposure with a significant risk of decreased ICSI outcomes. METHODS This retrospective study included 633 women who were part o...

OBJECTIVE To verify whether microinjection into retrieved oocytes of motile spermatozoa with morphologically normal nuclei, strictly defined by high power light microscopy (x >6000), improves the IVF/intracytoplasmic sperm injection (ICSI) pregnancy rate in couples with repeated ICSI failures. DESIGN Comparative prospective study testing routine IVF/ICSI outcome parameters against those of mo...

The aim of this study was to determine the incidence of congenital malformations in a complete cohort of children born after intracytoplasmic sperm injection (ICSI). The medical records were retrieved for 1139 infants, 736 singletons, 200 sets of twins and one set of triplets. The total number of infants with an identified anomaly was 87 (7.6%), 40 of which were minor. The incidence of malforma...

This paper describes a new cooperative Intelligent Transportation System architecture that aims to enable collaborative sensing services. The main goal of this architecture is to improve transportation efficiency and performance. The system, which has been proven within the participation in the ICSI (Intelligent Cooperative Sensing for Improved traffic efficiency) European project, encompasses ...

This paper outlines issues and explores options for augmenting the current structural MDE scoring with the goal of obtaining more meaningful measures of performance. We propose event-based statistical significance measures (similar to STT), evaluation of confidence predictions (important to downstream processing applications), and accounting for annotation differences (due to inherent variabili...

Objective: To find if the zona thinning size (in length) of the embryos transferred had any effects on the implantation and clinical pregnancy rates. Design: A prospective randomized study Setting: Infertility and Assisted Reproductive Techniques Centres. Material methods: Sixty infertile women (≥38 years old) who underwent ICSI-ET procedures and accepted to join this study were enrolled. Women...

The aim of the present study was to test whether it is possible to eliminate a high percentage of morphologically abnormal sperm in male ejaculate by assisted reproduction using the intracytoplasmic sperm injection (ICSI) method. Treatment success was evaluated by comparing fertilization, clinical pregnancy and reproduction rates between males with heavy teratospermia (≤1% morphologically norma...
