Embryo implantation represents a complex process vital in ensuring the normal development of pregnancy. Whether embryo implantation is the goal of natural conception or assisted reproductive treatment, the environment within the uterine cavity must be optimised in order to increase the chance of pregnancy.
This thesis uses a mixture of research methods to investigate potential approaches to improving embryo implantation. Below are the key findings from this thesis:
1. The vitamin D status in women undergoing assisted reproductive treatment is important. An interventional trial would prove or disprove the merits of vitamin D deficiency treatment in these women.
2. There is not enough evidence to suggest a clear association between vitamin D and recurrent miscarriage, however there is a strong argument for biological plausibility.
3. The use of endometrial fluid collected at the time of embryo transfer in women undergoing assisted reproductive treatments for metabolomics analysis is possible.
4. Women with hydrosalpinx associated tubal infertility should be offered salpingostomy as a treatment option as the natural conception rates are similar to that achieved in in vitro fertilisation treatment
