The effect of smoking on Assisted Reproductive Technology (ART) results in male was considered as a deleterious factor in pregnancy outcome among IVF patients. Male smoking is associated with lower success rate in ICSI and IVF couples. Smoking significantly decreased live birth rates and has a deleterious effect on sperm’s DNA. This study was designed to evaluate the effect of male cigarettes s...

The aim of this study was to evaluate embryo development of prepubertal goat oocytes fertilised by ICSI according to their diameter. Three experiments were carried out to achieve this objective. In all experiments, oocytes were matured in TCM199 supplemented with hormones, cysteamine and serum for 27 h at 38.5 degrees C. In Experiment 1, we studied the nuclear stage of goat zygotes produced by ...

Introduction Sperm DNA integrity is a crucial paternal factor affecting fertilization and pregnancy rates, as well as embryo development. Case The present case report describes the successful pregnancy after testicular sperm aspiration (TESA) combined with intracytoplasmic sperm injection (ICSI) (TESA-ICSI) in a couple where the male presented high sperm DNA fragmentation. In order to sort dama...

have become available for most categories of infertile couples. In 1988, Lanzendorf et al. reported an experiment with intracytoplasmic sperm injection (ICSI) on human oocytes,1 and in 1992, ICSI was presented as a successful method of treatment for certain types of male infertility.2 The ICSI procedure involves the isolation of one particular spermatozoon that is subsequently injected directly...

Two case histories are presented documenting structural chromosome abnormalities in infertile males. The abnormalities were detected only after application of intracytoplasmic sperm injection (ICSI) was repeatedly unsuccessful or resulted in an abnormal pregnancy. A mosaic Robertsonian translocation 45,XY,der(13;13)(q10; q10)/46,XY,t(13;13)(p10;p10), der(13p;13p) incompatible with normal offspr...

The objective of this study was to determine whether or not abnormalities in the autosomal structure of the male partner have any influence on fertilization and early embryo development after intracytoplasmic sperm injection (ICSI). Thirty-seven couples in whom the male partners were examined by the same andrologist were included in this study. Six couples (group I) in whom the male partner pos...

Production efficiency of transgenic rats was compared directly between the routine pronuclear microinjection of exogenous DNA solution (PNMI-Tg method) and the ooplasmic injection of sperm cells exposed to exogenous DNA solution (ICSI-Tg method) using six DNA constructs. The overall production efficiency per treated oocyte in the ICSI-Tg method (mean 1.1%, range 0.2 to 3.1%) was similar to that...

This article aims to report successful live births after transfer of fresh blastocyst or vitrified/warmed blastocyst derived from intracytoplasmic sperm injection (ICSI) on day-1 of unfertilized mature eggs (so-called "rescue ICSI") with spindle examination using polarized light microscopy. Two couples who had rescue ICSI performed achieved a positive pregnancy result after the transfer of a fr...

background: we sought to determine the association between factors that affected clinical pregnancy and live birth rates in patients who underwent in vitro fertilization (ivf) and received intracytoplasmic sperm injection (icsi) and/or laser assisted hatching (lah), or neither. materials and methods: in this retrospective cohort study, the records of women who underwent ivf with or without icsi...

Since the introduction of intracytoplasmic sperm injection (ICSI) in 1992, the new technology has raised a series of basic moral issues. In this article, I present a brief review of this moral debate. I argue that even if we solve the moral problems of the debate, there is a residue of value issues. These value issues are crucial for the understanding of the dynamics of the health policy and th...
