OBJECTIVE To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on pregnancy rates (PR) in women undergoing ET. DESIGN Prospective, randomized, single-blinded placebo-controlled clinical trial. SETTING Research and laboratory facilities. PATIENT(S) A total of 309 patients, less than 45 years old, undergoing cryopreservation embryos transplant or fresh cycle IVF w...

A follow-up study was performed to investigate the impact of the detection of a chromosome abnormality in infertile men who are candidates for intracytoplasmic sperm injection (ICSI) treatment. In this collaborative study between clinical genetics centres and fertility clinics in the Netherlands, 75 ICSI couples of which the male partners had a chromosome abnormality were included. All couples ...

OBJECTIVE To investigate whether poor response to controlled ovarian stimulation (COS) is due to a qualitative decline in ovarian function. METHODS This retrospective cohort study included 436 patients younger than 35-years old, undergoing COS for intracytoplasmic sperm injection (ICSI). Patients with four or fewer MII oocytes after COS (poor-responder group, PR, n = 52) were age-matched with...

BACKGROUND Our aim was to determine the effect of single endometriomas ≤3 cm in diameter per se on ovarian reserve in intracytoplasmic sperm injection (ICSI) cycles. METHODS We enrolled 19 consecutive infertile patients (29 cycles) who had unilateral single endometriomas ≤3 cm in diameter and who underwent ICSI. RESULTS The mean age of the patients was 33.3 ± 4.9 years. The mean diameter of...

The main objective of the Walking Egg non-profit organization is the implementation of good quality and affordable infertility centres in resource-poor countries. Three levels of assistance are suggested: A level 1 infertility clinic is a basic infertility clinic capable of offering semen analysis, hormonal assays, follicular scanning, ovulation induction and intrauterine inseminations. Level 2...

The ovarian stimulation of poor responders still remains a challenging task for clinicians. There are numerous strategies that have been suggested to improve the outcome in poor responders but there is still no one pituitary down-regulation protocol that best suits all women with such condition. Traditional GnRH agonist flare and long luteal phase protocols do not appear to be advantageous. Red...

OBJECTIVE To determine whether the short or long protocol for controlled ovarian hyperstimulation works better in older patients undergoing IVF. DESIGN Controlled, randomized study. SETTING A single private IVF center. PATIENT(S) Two hundred twenty infertile women aged > or = 40 years undergoing IVF. INTERVENTION(S) At their first IVF cycle, the women were randomized into two study grou...

The objective of the present study was to analyse the influence of motility on the results of intracytoplasmic sperm injection (ICSI) when testicular spermatozoa are used for microinjection and to correlate this with testicular histology. A total of 197 ICSI treatment cycles (167 couples) was analysed retrospectively in which testicular spermatozoa were used, because of complete azoospermia, fo...

BACKGROUND The risk of placenta previa may be increased in pregnancies conceived by assisted reproduction technology (ART). Whether the increased risk is due to factors related to the reproductive technology, or associated with maternal factors, is not known. METHODS In a nationwide population-based study, we included 845,384 pregnancies reported to the Medical Birth Registry of Norway betwee...
