Title: The impact of duration of freezing of IVF embryos on pregnancy and perinatal outcomes – analysis of UK national data

Background of the research proposal: 

IVF (in-vitro fertilisation) is the recommended treatment for couples with unresolved infertility. It involves mixing eggs and sperm to create embryos which are then cultured in the laboratory. Usually, the best embryo is then put back in the womb, while others can be frozen for future use. The use of frozen embryos has become popular across the globe in recent years, accounting for 41% of all IVF treatments in 2019 in UK. Although many embryos are frozen for short durations, others can be kept in the freezer for many months or years and it is believed that patients can use them at any time without affecting their chances of pregnancy rates or the health of their babies.

Aim: To find an association between the duration of embryo freezing and pregnancy and perinatal outcomes among couples treated for infertility

Dataset: This study will use information of treatments undertaken between 2000 and 2019 from the Human Fertilisation Embryology Authority (HFEA) database which holds data of all IVF treatments undertaken in the UK licensed clinics, to explore the impact of the duration of embryo freezing on IVF live birth rate and safety of children.

Exposure:  the duration of embryo freezing 

Outcomes: The main outcome measures are live birth, gestational age (preterm vs term), birthweight (small/large for gestational age vs normal for gestational age) and congenital anomalies. The results of the proposed research will provide patients and clinicians with the necessary information so that they can make informed choices in the future.

Statistical Analyses: The student is expected to come up with appropriate statistical methods and use machine learning techniques to address the research question or objective of the study.
