An ultrasonographic evaluation of the endometrium was performed in 158 patients undergoing ovarian stimulation for an in-vitro assisted reproduction programme. Endometrial thickness was evaluated in 109 patients undergoing in-vitro fertilization (IVF) for female indications and in 49 patients undergoing intracytoplasmic sperm injection (ICSI) for male indications. The maximal endometrial thickn...

OBJECTIVE To determine the usefulness of and cost-effectiveness of antisperm antibody testing in the prediction of poor fertilization rates in couples undergoing IVF. DESIGN Retrospective cohort study. SETTING A hospital-based reproductive endocrinology and infertility practice. PATIENT(S) Male partners of 251 couples undergoing IVF between 1992 and 1997. MAIN OUTCOME MEASURE(S) Fertili...

Objective: To investigate the effect of sperm DNA fragmentation index (DFI) on the clinical outcomes of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Methods: Infertile couples were prospectively recruited in the Reproductive Center in Jiaozuo Maternal and Child Care Service Centre in Henan, China, from July 2015 to December 2016. All the recruited 228 infertile coup...

Short incubation time prevents deleterious effects of cumulus cell degeneration and excess spermatozoa in IVF embryos. We performed a short incubation (3 h) protocol in 328 IVF cycles, in order to compare the developmental potential of regular IVF embryos with those originating from 316 cycles entered our intracytoplasmic sperm injection (ICSI) programme over the same period. Embryo transfers w...

BACKGROUND Over a million children have been born from assisted conception worldwide. Newer techniques being introduced appear less and less 'natural', such as intracytoplasmic sperm injection (ICSI), but there is little information on these children beyond the neonatal period. METHODS 540 ICSI conceived 5-year-old children from five European countries were comprehensively assessed, along wit...

BACKGROUND ICSI bypasses the sperm-oolemma interactions that, in normal fertilization, depend on completion of the acrosome reaction. Morphological changes in the acrosomes of sperm in the ooplasm were therefore examined following IVF and ICSI using pig gametes. METHODS In-vitro-matured porcine oocytes were used for ICSI or IVF. Oocytes were then stained with fluorescein isothiocyanate-conjug...

The value of measuring the endometrial thickness and studying the endometrial receptivity in the context of assisted conception remains a contentious issue. A prospective analysis was carried out to determine the effect of endometrial thickness on IVF - embryo transfer/ICSI outcome in dedicated Assisted Reproductive Technology (ART) units in Abuja and Rivers State, Nigeria. Two hundred and fift...

objective: currently, there is no agreement on the optimal urinary derived human chorionic gonadotropin (u-hcg) dose requirement for initiating final oocyte maturation prior to oocyte collection in in vitro fertilization (ivf), but doses that range from 2500- 15000 iu have been used. we intended to determine whether low dose u-hcg was effective for oocyte maturation in ivf/intracytoplasmic sper...

BACKGROUND To compare the frequency of Y-chromosome microdeletions in Japanese and African azoospermic and oligozoospermic men and describe embryo characteristics and reproductive outcome following in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI). METHODS Our study was performed prospectively at two centers, a private IVF clinic and a university hospital. Japanese and...

Predicting the outcome of in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) is one main goal of the present research on assisted reproduction. To understand whether density gradient centrifugation (DGC), used to select sperm, can affect sperm DNA integrity and impact pregnancy rate (PR), we prospectively evaluated sperm DNA fragmentation (sDF) by TUNEL/PI, before and after DG...
