BACKGROUND To determine the differences in sperm quality and results of intracytoplasmic sperm injection (ICSI) cycles between three groups of male factor infertile couples: oligozoospermic, obstructive azoospermic and non-obstructive azoospermic. MATERIALS AND METHODS In this prospective cohort study, 628 male factor infertile couples who underwent ICSI cycles from April 2004 to March 2006 w...
BACKGROUND In 2004, a law regulating assisted reproduction techniques (ART) was passed in Italy. The new rules allow for the formation and transfer of a maximum of three embryos at one time, whereas embryo selection and embryo storage are prohibited. The aim of this study is to evaluate the impact of these restrictions on ICSI outcome in couples affected by severe male factor infertility. MET...
Many infertility clinics program ICSI directly in their IVF treatment plans due to the fear of failed or poor fertilization rates. A number still however perform conventional insemination. To aid patients who fail insemination, “rescue ICSI” is sometimes performed on oocytes that fertilize, allowing salvage cycle. This study analyzes pregnancy outcomes were able receive rescue ICSI; more specif...
The evidence of risk for birth defects due to artificial reproductive technology (ART) cycles is not yet clear. However, there may be a possible link between ART cycles and epigenetic abnormalities. Abdominal cysts are rarely seen pathologies after intracytoplasmic sperm injection (ICSI) cycles. A giant mesenteric cyst was diagnosed in one of the ICSI twins by ultrasonograhic examination at 14t...
Sperm DNA damage is prevalent among infertile men and is known to influence natural reproduction. However, the impact of sperm DNA damage on assisted reproduction outcomes remains controversial. Here, we conducted a meta-analysis of studies on sperm DNA damage (assessed by SCSA, TUNEL, SCD, or Comet assay) and clinical pregnancy after IVF and/or ICSI treatment from MEDLINE, EMBASE, and PUBMED d...
background: the use of assisted reproductive technology (art) is increasing in the world. the rate, efficacy and safety of art are very different among countries. there is an increase in the use of intra cytoplasmic sperm injection (icsi), single fresh embryo transfer (et) and frozen-thawed embryo transfer (fet). objective: the objective of this study was to compare pregnancy rate in fresh et a...
BACKGROUND The effect of progesterone elevation (PE) on the day of human chorionic gonadotropin (hCG) administration on the pregnancy outcomes of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles is a matter of ongoing debate. The replacement of cleavage-stage embryos with blastocyst-stage embryos for transfer was proposed to avoid the possible impairment of PE in fresh ...
Background One of the important complications of assisted reproductive technologies is multiple pregnancy, the aim of the present study was to indentify the risk factors of multiple pregnancy independent of number of transfred embryos. MaterialsAndMethods This retrospective study reviewed the medical records of patients underwent intracytoplasmic sperm injection (ICSI) cycle in Royan Institute ...
STUDY QUESTION How do live birth rates compare after intracytoplasmic sperm injection (ICSI) for men with obstructive azoospermia when using sperm derived from testicular sperm extraction (TESE) versus microsurgical epididymal sperm aspiration (MESA)? SUMMARY ANSWER Our study suggests that proximal epididymal sperm (from MESA) result in higher live birth rates as compared with testicular sper...
