Introduction The corpus luteum (CL) is dependent on luteal vascular permeability, which is controlled by human chorionic gonadotropin (hCG) via vascular endothelial growth factor (VEGF). In this study we investigated the role of a potential VEGF antagonist pathway - Slit2/Robo4 - and its influence on endothelial cell adhesion. Materials and Methods Luteinized granulosa cells (LGCs) were stimulated with hCG in the absence or presence of a VEGF inhibitor. The expression of VEGF and Slit2 were measured. Human umbilical vein endothelial cells (HUVECs) were stimulated with Slit2 or VEGF, and gene expressions of cadherin 5 (CDH5) and claudin 5 (CLDN5) were measured...

Conventional ovarian stimulation protocols for IVF are designed to achieve maximum oocyte yields. Conventional protocols, however, are associated with patient discomfort, increased risk of ovarian hyperstimulation syndrome and higher costs. In recent years, mild stimulation protocols have risen in popularity. These protocols typically use lower doses (≤150 IU/day), shorter duration of exogenous gonadotrophins, or both, compared with conventional protocols, with the goal of limiting the number of retrieved oocytes to less than eight...

STUDY QUESTION: How does the efficacy and safety of a fixed-ratio combination of recombinant human FSH plus recombinant human LH (follitropin alfa plus lutropin alfa; r-hFSH/r-hLH) compare with that of r-hFSH monotherapy for controlled ovarian stimulation (COS) in patients with poor ovarian response (POR)? SUMMARY ANSWER: The primary and secondary efficacy endpoints were comparable between treatment groups and the safety profile of both treatment regimens was favourable...

BACKGROUND: Clomiphene citrate (CC) is generally considered first-line treatment in women with anovulation due to polycystic ovary syndrome (PCOS). Ovulation induction with follicle-stimulating hormone (FSH; gonadotrophins) is second-line treatment for women who do not ovulate or conceive while taking CC. Metformin may increase the effectiveness of ovulation induction with gonadotrophins and may promote safety by preventing multiple pregnancy. OBJECTIVES: To determine the effectiveness and safety of metformin co-treatment during ovulation induction with gonadotrophins with respect to rates of live birth and multiple pregnancy in women with PCOS...

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) in assisted reproductive technology (ART) cycles is a treatment-induced disease that has an estimated prevalence of 20% to 33% in its mild form and 3% to 8% in its moderate or severe form. These numbers might even be higher for high-risk women such as those with polycystic ovaries or a high oocyte yield from ovum pickup. OBJECTIVES: The objective of this overview is to identify and summarise all evidence from Cochrane systematic reviews on interventions for prevention or treatment of moderate, severe and overall OHSS in couples with subfertility who are undergoing ART cycles...

OBJECTIVE: To compile and assess data about complication and success rates for in vitro fertilization (IVF) of women with systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS). To date, such data are sparse. METHODS: This retrospective study described women with SLE and/or APS who have had at least 1 IVF cycle. RESULTS: Thirty-seven women with SLE (n = 23, including 8 with antiphospholipid antibodies), SLE with APS (n = 4), or primary APS (n = 10) underwent 97 IVF procedures...

Final oocyte maturation with Human Chorionic Gonadotropin (hCG) and ovarian stimulation with Follicle Stimulation Hormone (FSH) combined with Gonadotrophin-releasing Hormone (GnRH) antagonist to block Luteinizing hormone (LH) surge is a standard procedure of in vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI). However, GnRH agonist has been replacing the use of hCG in certain situations, especially in patients at risk of Ovarian Hyperstimulation Syndrome (OHSS). Some studies have also shown advantages in the combined use of GnRH agonist concurrently with hCG in inducing final oocyte maturation, a treatment known as "Dual Trigger"...

Ovarian hyperstimulation syndrome is a rare disease among preterm infants. This syndrome was first described in 1985 in four infants with a gestational age of <30 weeks. Several explanations for this syndrome have been suggested namely the immaturity of Hypothalamic-Pituitary-Gonadal (HPG) axis, lack of negative feedback, increased sensitivity of Follicle Stimulating Hormone (FSH) receptors due to mutation and high level of estradiol. In this report, a case of hyperstimulation syndrome in a newborn with gestational age of 30 weeks is presented and the probable mechanisms in the literature are discussed...

Evidence-based medicine is the principal approach to medical practice. There are several debatable issues in infertility, which require clarification. Over the past 20 years, reliable methodology has been developed for the management of infertile couples. This includes high quality diagnostic and therapeutic procedures, which are applied in highly specialised infertility centres. The European Board and College of Obstetrics and Gynaecology (EBCOG) has published Standards of Care for Women's Health in Europe, which should be the cornerstone for the clinicians and service providers in the European Union to establish common protocols within their centres...

Over the past few years, the use of Gonadotropin-releasing-hormone (GnRH)-agonist for final oocyte maturation in GnRH-antagonist-protocols in stimulated IVF/ICSI cycles has gained worldwide acceptance, as this approach reduces significantly the risk for development of ovarian hyperstimulation syndrome (OHSS). Final oocyte maturation with GnRH-agonist leads to sever luteolysis, which cannot be counterbalanced using standard luteal phase support with purely progesterone (P4) application and therefore administration of hCG or high doses of P4 is considered to be essential to prevent/counteract luteolysis...

Background: A 32-year-old woman with tubal factor infertility due to bilateral laparoscopic salpingectomy conceived twins with in vitro fertilization (IVF). She developed moderate ovarian hyperstimulation syndrome which was treated with anticoagulant therapy. The subsequent course of the twin pregnancy was normal until the 17th week of gestation when she presented to hospital because of a sharp pain in the right lower abdomen which ceased after admission. Case: Except for a single incident of vomiting, patient had no other subjective symptoms...

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) occurs when ovaries are overstimulated and enlarged due to fertility treatments resulting in a shift of serum from the intravascular space to the third space, mainly the abdominal cavity. It is the most serious complication of ovarian hyperstimulation for assisted reproduction. CASE REPORT: We present the case of a 40-year-old woman who presented with abdominal bloating and nausea 2 weeks after undergoing in vitro fertilization (IVF); she was diagnosed by an outside radiology ultrasound as having a ruptured ovarian cyst...

BACKGROUND: Subfertility due to anovulation is a common problem in women. First-line oral treatment is with antioestrogens such as clomiphene citrate, but resistance may be apparent with clomiphene. Alternative and adjunctive treatments have been used including tamoxifen, dexamethasone, and bromocriptine. The effectiveness of these is to be determined. OBJECTIVES: To determine the relative effectiveness of antioestrogen agents including clomiphene alone or in combination with other medical therapies in women with subfertility associated with anovulation, possibly caused by polycystic ovarian syndrome...
