BACKGROUND In unexplained and mild male factor subfertility, both intrauterine insemination (IUI) and in-vitro fertilisation (IVF) are indicated as first line treatments. Because the success rate of IUI is low, many couples failing IUI subsequently require IVF treatment. In practice, it is therefore important to examine the comparative outcomes (live birth-producing pregnancy), costs, and cost-...

BACKGROUND The largest percentage of failed invitro fertilization (IVF (cycles, are due to lack of implantation. As hereditary thrombophilia can cause in placentation failure, it may have a role in recurrent IVF failure. OBJECTIVE Aim of this case-control study was to determine whether hereditary thrombophilia is more prevalent in women with recurrent IVF failures. MATERIALS AND METHODS Cas...

Implantation failure could be related to antiphospholipid antibodies (aPL). We retrospectively analyzed the usefulness of aPL determination in women undergoing IVF. Conventional aPL of the antiphospholipid syndrome, lupus anticoagulant (LA), anticardiolipin antibodies (aCL), anti-β2glycoprotein I (a β2GPI) antibodies, and IgG and IgM isotypes as well as IgA isotype were analyzed in women presen...

BACKGROUND/AIM Implantation failure after embryo transfer is one of the main problems of in vitro fertilization (IVF) and intrauterine pathologies can lead to unsuccessful outcome. The aim of this study was to determine if hysteroscopic examination of uterine cavity and consequent treatment of intrauterine lesions prior to IVF could improve the pregnancy rate in women under 38. METHODS This s...

Through pioneering human IVF as a global infertility treatment, Robert Edwards and his clinical partner Patrick Steptoe launched the field of IVF endocrinology. Following repeated failures with oocytes collected in human menopausal gonadotrophin (HMG) primed cycles timed to injection of human chorionic gonadotrophin (HCG), the first successful IVF pregnancy came from a spontaneous menstrual cyc...

Increased antiphospholipid antibody prevalence has been demonstrated by a number of recent studies in in-vitro fertilization (IVF) patients but the potential effects of antiphospholipid antibodies on the different components of the reproductive process and the consideration of whether to test IVF patients for antiphospholipid antibodies are controversial. The present study was undertaken to inv...

BACKGROUND We investigated whether hereditary thrombophilia is more prevalent in women with recurrent IVF-embryo transfer failures. METHODS This case-control study was conducted in an academic tertiary care hospital and compared 45 women with a history of four or more failed IVF cycles (group A) with 44 apparently healthy women matched for age and ethnic origin (group B). All participants wer...

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 Only 25% of IVF transfer cycles lead to a clinical pregnancy, calling for continued technical progress but also more in depth analysis of patients' individual characteristics. The interleukin-1 (IL-1) system and matrix metalloproteinases (MMPs) are strongly implicated in embryo implantation. The genes coding for IL-1Ra (gene symbol IL-1RN), IL-1beta, MMP2 and MMP9 bear functional pol...
