BACKGROUND To study the effect of metformin before and during assisted reproductive technology (ART) on the clinical pregnancy rate (CPR) in non-obese women with polycystic ovary syndrome (PCOS). METHODS A multi-centre, prospective, randomized, double-blind study was conducted in eight IVF clinics in four Nordic countries. We enrolled 150 PCOS women with a body mass index <28 kg/m(2), and tre...
The predictive value of sperm chromatin integrity for pregnancy outcome following in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) was studied in 24 men attending a university-based assisted reproductive techniques laboratory using the flow cytometric sperm chromatin structure assay (SCSA). The SCSA is a measure of the susceptibility of sperm DNA to low pH-induced denatu...
Spermatid specific thioredoxin-3 (SPTRX3 or TXNDC8) is a testis/male germ line specific member of thioredoxin family that accumulates in the superfluous cytoplasm of defective human spermatozoa. We hypothesized that semen levels of SPTRX3 are reflective of treatment outcome in assisted reproductive therapy (ART) couples treated by in vitro fertilization (IVF) or intracytoplasmic sperm injection...
BACKGROUND Prenatal screening and diagnosis of chromosomal abnormalities especially Down's syndrome in IVF pregnancies are complicated by higher maternal age, a high multiple pregnancy rate, a high risk of a vanishing twin and an increased risk of chromosomal abnormalities, particularly in pregnancies after ICSI. The aim of the present systematic review was to evaluate the findings of first tri...
BACKGROUND Earlier reviews have suggested that IVF/ICSI pregnancies are associated with higher risks. However, there have been recent advances in the way IVF/ICSI is done, leading to some controversy as to whether IVF/ICSI singletons are associated with higher perinatal risks. The objective of this systematic review was to provide an up-to-date comparison of obstetric and perinatal outcomes of ...
BACKGROUND Success rates of assisted reproductive techniques (ART) are approximately 30%, with the most important limiting factor being embryo implantation. Mechanical endometrial injury, also called 'scratching', has been proposed to positively affect the chance of implantation after embryo transfer, but the currently available evidence is not yet conclusive. The primary aim of this study is t...
OBJECTIVE To examine the relationship of early human embryonic development parameters to day 3 reactive oxygen species (D-3 ROS) levels in culture media. DESIGN Prospective study. SETTING Tertiary care hospital. PATIENT(S) Patients were undergoing IVF (n=92; 36 with intracytoplasmic sperm injection [ICSI]). INTERVENTION(S) The D-3 ROS levels in sample and control of each embryo culture ...
OBJECTIVE The objective of this study was to examine the relationship of early human embryonic development parameters with day 1 culture media total antioxidant levels (day 1 TAC). DESIGN Prospective study. SETTING Patients undergoing assisted reproduction (ART) in a teaching hospital. PATIENT(S) Patients undergoing conventional IVF (n = 153; 167 cycles) and intracytoplasmic sperm injecti...
Introduction Smoking is a serious problem for the health care system. Many of the compounds identified in cigarette smoke have toxic effects on the fertility of both females and males. The purpose of this study was to determine whether smoking affects clinical factors during IVF/ICSI therapy in a single-center reproductive unit. Material and Methods In a retrospective study of 200 IVF/ICSI cy...
OBJECTIVE To investigate associations between preconception dietary patterns and IVF/intracytoplasmic sperm injection (ICSI) outcomes validated by biomarkers of the homocysteine pathway. DESIGN Observational prospective study. SETTING A tertiary referral fertility clinic at the Erasmus University Medical Centre, Rotterdam, The Netherlands. PATIENT(S) One hundred sixty-one couples undergoi...
