BACKGROUND The media that are used to culture human preimplantation embryos are considered to be an important factor for the success rates of IVF/ICSI. Here, we present a systematic review of randomized controlled trials (RCTs) on the effect of culture media on IVF/ICSI success rates. METHODS RCTs published between January 1985 and July 2012 were eligible for inclusion. The primary outcome was ...
BACKGROUND There is considerable uncertainty as to the significance of a high sperm DNA fragmentation index (DFI) for achieving a successful pregnancy. METHODS The sperm DFI of 124 patients undergoing 192 IVF cycles and of 96 patients undergoing 155 ICSI cycles was determined using the sperm chromatin structure assay on neat sperm. RESULTS The rate of continuing pregnancies in ICSI cycles (...
The introduction and widespread application of assisted reproduction techniques have raised major concern about the outcome of resulting pregnancies, as well as about the offspring's health. It seems that pregnancies achieved after standard in-vitro fertilization (IVF) bear an increased risk for prematurity and low birth weight. On the other hand, pregnancy outcome of singletons achieved after ...
In this paper, a retrospective cohort study was conducted to the high ovarian responders in GnRH-antagonist protocols of IVF/ICSI cycles. The purpose of the study is to investigate whether dual triggering of final oocyte maturation with a combination of gonadotropin-releasing hormone (GnRH) agonist and human chorionic gonadotropin (HCG) can improve the clinical outcome compared with traditional...
OBJECTIVE To determine whether the presence of a Y microdeletion confers any adverse effects on in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI) outcome. DESIGN Retrospective case-control study. SETTING Academic infertility center. PATIENT(S) A total of 17 patients with Y microdeletions who attempted IVF/ICSI cycles at our center between March 1996 and March 2002 were...
BACKGROUND The reasons for increased birth defect prevalence following in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) are largely unknown. Classification of birth defects by pathology rather than organ system, and examination of the role of embryo freezing and thawing may provide clues to the mechanisms involved. This study aimed to investigate these two factors. MET...
BACKGROUND Factors influencing a pregnant woman's decision to accept prenatal testing are largely undefined. Our study aimed to compare the acceptance rate of prenatal diagnosis in women who conceived through IVF or ICSI (cases) with that of women who conceived spontaneously (controls). METHODS Retrospective chart review in Lebanon of all primiparas carrying singletons who were offered prenat...
BACKGROUND The sperm chromatin structure assay (SCSA) has been suggested as a predictor of fertility in vivo as well as in vitro. The available data however, have been based on limited numbers of treatments. We aimed to define the clinical role of SCSA in assisted reproduction. METHODS A total of 998 cycles [387 intrauterine insemination (IUI), 388 IVF and 223 ICSI] from 637 couples were incl...
In order to study the impact of procedures of IVF/ICSI technology on sex ratio in China, we conducted this multi-center retrospective study including 121,247 babies born to 93,895 women in China. There were 62,700 male babies and 58,477 female babies, making the sex ratio being 51.8% (Male: Female = 107:100). In univariate logistic regression analysis, sex ratio was imbalance toward females of...
