Objective: To study the outcome of ICSI conceived children in our IVF center; their growth, their psychomotor development and to find out possible birth defects and genetic anomalies. Material and Methods: This is a prospective survey about ICSI conceived children and naturally conceived children in our IVF center over the period between 2007 and 2012. One hundred ICSI children aged between 2 a...

IMPORTANCE Intracytoplasmic sperm injection (ICSI) is increasingly used in patients without severe male factor infertility without clear evidence of a benefit over conventional in vitro fertilization (IVF). OBJECTIVE To assess national trends and reproductive outcomes for fresh IVF cycles (embryos transferred without being frozen) following the use of ICSI compared with conventional IVF with ...

BACKGROUND Sperm of poor quality can negatively affect embryo development to the blastocyst stage. The aim of this comparative prospective randomized study was to evaluate the role of an intracytoplasmic morphologically selected sperm injection (IMSI) in the same infertile couples included in the programme of intracytoplasmic sperm injection (ICSI) due to their indications of male infertility w...

BACKGROUND Puberty is a critical period for the development of cardio-metabolic disturbances, including a more central body fat distribution. It is still unclear if IVF and more specifically ICSI, can permanently and detrimentally affect body fat accumulation in the human offspring. Therefore, adiposity and body fat distribution in 14-year-old adolescents born after ICSI were investigated. ME...

BACKGROUND Sperm DNA damage is common amongst infertile men and may adversely impact natural reproduction, IUI-assisted reproduction and to a lesser degree IVF pregnancy. The aim of this study was to examine the influence of sperm DNA damage on the risk of spontaneous pregnancy loss after IVF and ICSI. METHODS We conducted a systematic review and meta-analysis of studies on sperm DNA damage a...

BACKGROUND ICSI bypasses the sperm-oolemma interactions that, in normal fertilization, depend on completion of the acrosome reaction. Morphological changes in the acrosomes of sperm in the ooplasm were therefore examined following IVF and ICSI using pig gametes. METHODS In-vitro-matured porcine oocytes were used for ICSI or IVF. Oocytes were then stained with fluorescein isothiocyanate-conjug...

BACKGROUND Most studies examining the use of ICSI for cases of elevated sperm DNA fragmentation report poor pregnancy and implantation rates. ICSI with testicular sperm samples has recently been suggested for these cases. Here we test a less invasive approach based on oral antioxidant treatment prior to ICSI with ejaculated spermatozoa. METHODS Thirty-eight men with an elevated (> or =15%) pe...

Objective: To assess the influence of MII oocyte morphology on the fertilization outcome and embryo development in ART cycles. Since, age may affect the quality of oocyte, the role of women's age was also evaluated following IVF or ICSI cycles. Materials and Methods: 200 MII oocytes from 30 IVF and ICSI cycles were evaluated. The morphology of oocytes that were fertilized in IVF cycles (IVF+) w...

Abstract While intracytoplasmic sperm injection (ICSI) is an asset in human Assisted Reproduction Technologies (ART), its outcomes, terms of blastocyst, still unacceptably low ruminants. The picture typically found ICSI derived bovine and ovine embryos asymmetry between a high activation rate, marked by pronuclear development, first cleavage rate. Abnormal centriole function has been indicated ...
