Plain English Summary
Background and study aims
In vitro fertilisation (IVF) is a technique used to help people with fertility problems to have a baby. During IVF, the egg is fertilised by the sperm outside of the body to create an embryo and then returned to the woman’s uterus to develop. Although IVF has become more and more successful in recent years, there is still a relatively high failure rate. The exact reasons for this are not known, however recent studies suggest that levels of different hormones in the body could play a role. The production of different hormones is determined by genes, which can vary greatly from person to person. The aim of this study is to find out whether there is a relationship between the different variants of hormonal genes and the success of IVF treatment.
Who can participate?
Women aged 20 to 45 who are suitable for IVF treatment.
What does the study involve?
All of the participants undergo standard IVF treatment and donate 10 ml of blood for the genetic variants tests.
What are the possible benefits and risks of participating?
There are no additional benefits or risks for those taking part in the study as the treatment process is the same for those who are and are not taking part in the study.
Where is the study run from?
Lee Women's Hospital (Taiwan)
When is the study starting and how long is it expected to run for?
December 2013 to December 2016
Who is funding the study?
United Arab Emirates University (United Arab Emirates)

In vitro fertilization (IVF)
All participating patients received controlled ovarian hyperstimulation protocols and oocyte retrieval procedures to get a number of oocytes. These oocytes were processed with in vitro fertilization/intracytoplasmic sperm injection to get embryos. Then we transferred the embryos back into the uterus. The duration of observation is at least one month. If a patient became pregnant, we followed her up for about one year until the delivery of baby.
Primary outcome measure
Oocyte number, measured using microscopy observation at the time of oocyte retrieval
Secondary outcome measures
1. Embryo quality is measured using microscopy observation for the number of blastomere, fragmentation degree at day 3 or day 5 after oocyte retrieval
2. Pregnancy rate is measured using serum beta-HCG test and ultrasound examination at 18 days and 32 days after oocyte retrieval, respectively
3. Implantation rate is measured using the total sac numbers divided by total transfer embryo number at the time of ultrasound examination
