Title: The Efficacy of Endometrial Biopsy on the Outcome of In Vitro Fertilization (IVF) /Intra-Cytoplasmic Sperm Injection (ICSI) Treatment (Endoscratch): A Feasibility Pilot Study
Brief Summary: This study aims to see if taking a small sample from the lining of the womb (the 'scratch') before starting in vitro fertilization (IVF) treatment can influence the chance of getting pregnant and having a healthy, term baby.

This study also aims to explore why an embryo is not accepted or indeed rejected by the lining of the womb. This will be analysed by carefully looking at the sample taken from the lining of the womb under the microscope and analysing the levels of natural killer (NK) cells. These cells are thought to regulate the implantation process and to be altered in some women with infertility and miscarriage.
