BACKGROUND There is currently no consensus about indications for surgery for infertility associated with colorectal endometriosis. The aim of this study was to evaluate cumulative pregnancy rates (CPRs) after ICSI-IVF cycles in patients with colorectal endometriosis and to identify determinant factors of fertility outcome. METHODS Prospective longitudinal multicentre study from January 2005 t...

OBJECTIVE Compare the efficacy of surrogate or gestational carrier (GC) cycles to that of autologous in vitro fertilization (IVF)/intracytoplasmic sperm injections (ICSI) in patients with gynecologic or medical co-morbidities contraindicative to pregnancy. DESIGN Retrospective cohort study. SETTING Infertility patients from a single university hospital-based program from 1998-2009. INTERV...

INTRODUCTION Male infertility caused by azoospermia due to non-reconstructable obstruction or non-obstructive azoospermia can be treated by microsurgical epididymal aspiration (MESA) or testicular sperm extraction (TESE) followed by an intracytoplasmatic spermatozoa injection (ICSI). MATERIAL AND METHODS From 9/93 to 6/01, we carried out 1,025 ICSI procedures with aspirated epididymal or test...

OBJECTIVE To determine some major characteristic differences between two consecutive successful and unsuccessful intracytoplasmic sperm injection (ICSI) cycles in poor responders. MATERIALS AND METHODS Sixty women with poor ovarian response as determined using the Bologna criteria underwent ICSI cycles following an unsuccessful trial. Some parameters of both cycles including age, body mass in...

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 This study aimed to evaluate the effect of small intramural fibroids on the cumulative pregnancy, ongoing pregnancy, live birth and implantation rates after three IVF/ICSI attempts. METHODS The first three treatment cycles of women enrolled for IVF/ICSI over a 12-month period were analysed. Only patients with small (<or=5 cm) intramural fibroids not encroaching upon the endometrial...

STUDY QUESTION Have changes in assisted reproductive technology (ART) practice and outcomes occurred globally between 2003 and 2004? SUMMARY ANSWER Globally, ART practice has changed with an increasing prevalence of the use of ICSI rather than conventional IVF. In 2004, a small but increasing number of countries are incorporating single embryo transfer. There remain unacceptably high rates of...

STUDY QUESTION Does DPY19L2 status influence intracytoplasmic sperm injection (ICSI) outcomes with or without assisted oocyte activation (AOA)? SUMMARY ANSWER DPY19L2 mutations have no major impact on ICSI outcomes in globozoospermic patients. WHAT IS KNOWN ALREADY Globozoospermia is a rare and severe teratozoospermia characterized by round-headed spermatozoa lacking an acrosome. Recently, ...

Background Multiple pregnancies are an important complication of assisted reproductive technology (ART). The present study aims to indentify the risk factors for multiple pregnancies independent of the number of transferred embryos. MATERIALS AND METHODS This retrospective study reviewed the medical records of patients who underwent intracytoplasmic sperm injection (ICSI) cycles in Royan Inst...
