BACKGROUND GnRH agonist administration in the luteal phase has been suggested to beneficially affect the outcome of intracytoplasmic sperm injection (ICSI) and embryo transfer (ET) cycles. This blind randomized controlled study evaluates the effect of GnRH (Gonadotropine Releasing Hormone) agonist administration on ICSI outcome in GnRH antagonist ovarian stimulation protocol in women with 2 or ...

BACKGROUND In-vitro fertilization (IVF) is the treatment of choice for unresolved infertility. It comprises a number of key steps, each of which has to be negotiated before the next is attempted, but the factors which are associated with failure at each stage have not been reported. METHODS AND FINDINGS We analyzed anonymised national data on women undergoing their first fresh autologous IVF ...

The main perinatal complications of assisted reproduction include congenital malformation, chromosomal aberrations, multiple pregnancy, and prematurity. Earlier studies and in vitro fertilization (IVF) registries showed that there was no increased incidence of congenital malformations in children conceived by IVF/intracytoplasmic sperm injection (ICSI). However, a large Australian study has fou...

BACKGROUND The aim of this study is to assess the effect of body mass index (BMI) on outcomes of in vitro fertilization (IVF) / intracytoplasmic sperm injection (ICSI) among polycystic ovarian syndrome (PCOS) and non-PCOS patients. METHODS This was a retrospective cohort study that was performed in the Second Hospital of Hebei Medical University. Patients who were under 35 years old were incl...

background: despite numerous developments in the field of assisted reproduction, the implantation rate remains low. among the various reasons of implantation failure, endometrial regularity has an important role. hysteroscopy is an accurate method for evaluating the endometrial characteristics, with the ability to treat uterine pathology. objective: the aim of the present study was to evaluate ...

Infertility is defined as the inability to conceive after one year despite regular intercourse. The need for treatment and option are determined by evaluation process that starts this stage. Treatment mainly includes ovarian stimulation followed timed intercourse, intrauterine insemination (IUI), in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI). Choosing appropriate patient ...

In this retrospective study, we investigate the relationship between embryo arrest and polycystic ovary syndrome (PCOS) during in vitro fertilization-embryo transfer (IVF-ET). In this study, 667 subjects were enrolled, including 330 patients with PCOS and 337 subjects without PCOS. The subjects underwent in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) c...

Abstract Background The routine semen analysis fails to detect sperm DNA damage which contributes the majority of male factor infertility. Sperm fragmentation test (DFI) measures damage. Blastocyst formation is an important step in IVF ± ICSI. At present, literature lacks any data that correlates DFI and blastocyst formation. Main body abstract We searched MEDLINE other databases till 2020 for ...

BACKGROUND It has been suggested in the literature that low-dose aspirin leads to an increased number of oocytes in IVF/ICSI as well as a higher pregnancy rate. The aim of the present study was to investigate the effect of daily administration of low-dose aspirin, compared with placebo, on pregnancy rate in IVF and ICSI. METHODS This study was a prospective, randomized, double-blind placebo c...

BACKGROUND Underweight and overweight may affect reproduction and interfere with treatment of infertility. The purpose of this report is to describe the independent effect of body weight on treatment with IVF and ICSI. METHODS Records of 5019 IVF or ICSI treatments in 2660 couples were reviewed. The influence of body mass index (BMI) on treatment outcome was examined, after accounting for dif...
