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...

OBJECTIVE To examine the effects of different thermodynamic control systems on the temperature stability of human eggs during in vitro manipulation, with the integrity of meiotic spindles imaged using the LC-PolScope (Cambridge Research & Instrumentation, Inc., Woburn, MA). DESIGN We performed intracytoplasmic sperm injection (ICSI) and/or imaging of eggs with the temperature regulated by thr...

BACKGROUND Drugs administration as a pretreatment regiment before ICSI cycle in PCOs patients could enhance the success rate. OBJECTIVES The aim of this study was to compare the effectiveness of metformin with Simvastatin in patients with polycystic ovary syndrome (PCOs) candidates for intra-cytoplasmic sperm injection (ICSI) before starting the cycle. PATIENTS AND METHODS In this prospecti...

Sperm chromatin integrity has been being recognized as an important factor in male fertility. During normal fertilization, high quality sperm with intact chromatin are selected through natural selection in journey from vagina to fallopian tube. However, using Assisted Reproductive Techniques, particularly ICSI, the natural selection is bypassed. Therefore sperm with DNA breakage have the opport...

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...
