BACKGROUND Failure of implantation and conception may result from an inability of the blastocyst to escape from its outer coat, known as the zona pellucida. Artificial disruption of this coat is known as assisted hatching (AH) and has been proposed as a method for improving the success of assisted conception. OBJECTIVES To determine whether assisted(More)
Tubal disease is the cause of subfertility in approximately 30% of women, and 10-25% of these are due to proximal tubal obstruction. False-positive diagnosis of proximal tubal obstruction can be as high as 50%. A decrease in expertise in tubal microsurgery has resulted largely from the use of IVF as the treatment option for most causes of infertility and(More)
BACKGROUND Failure of implantation and conception may result from an inability of the blastocyst to escape from its outer coat, which is known as the zona pellucida. Artificial disruption of this coat is known as assisted hatching and has been proposed as a method for improving the success of assisted conception by facilitating embryo implantation. (More)
OBJECTIVE To ascertain if serum concentrations following injection of human chorionic gonadotropin (hCG) influenced the outcome of in vitro fertilisation (IVF) treatment and correlated to body mass index (BMI). STUDY DESIGN A prospective study conducted with the participation of 149 women undergoing IVF and/or intracytoplasmic sperm injection (ICSI)(More)
BACKGROUND Alpha and beta defensins have been isolated from various human tissues and form an important part of the innate immune system. Their role in implantation of the embryo has not yet been studied. This study was designed to detect both alpha and beta defensins in the mid luteal phase endometrium and investigate the correlation between the defensin(More)
This retrospective observational study was designed to study the impact of a dedicated antenatal clinic service on obstetric and neonatal outcomes among teenage mothers in the maternity unit of a district general hospital in the UK. Outcomes were measured to investigate improvement in obstetric and neonatal outcomes before, and 12 months after the(More)
OBJECTIVES To assess the effect of the phases of the moon on pregnancy rates in humans following in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) treatment. DESIGN Retrospective, observational study. SETTING Reproductive Medicine Unit, Liverpool Women's Hospital. PATIENT Complete data for all women undergoing assisted(More)
INTRODUCTION Defensins are cytotoxic peptides and have a well-defined role in host defense. Human alpha defensins 1-3 (HNP1-3) are primarily produced by peripheral neutrophils and constitute about 50% of the azurphil granule protein. Studies have suggested that peripheral neutrophils and the resident neutrophils in the ovary enhance the release of IL-8 and(More)
