Endometrial repair is essential for women's reproductive health. One in three women in the UK will suffer from a reproductive health problem1 such as polycystic ovarian syndrome (3.5 million), heavy menstrual bleeding (3.5 million) or endometriosis (1.5 million). These common disorders cause debilitating, lifechanging symptoms and are associated with dysregulated endometrial repair. We need to understand how endometrial repair is regulated in order to develop new therapies for women's reproductive health disorders.
Each month, the endometrium must repair following menstruation in order to maintain healthy function and ensure ongoing fertility. Macrophages are essential mediators of tissue repair, but we lack fundamental knowledge about how they are regulated in the endometrium. Although there is consensus that macrophages are necessary for endometrial repair, their nature, origins, and the environmental factors that control their behaviour remain poorly understood thereby limiting our understanding of their function.
Androgens are important for controlling endometrial function, but excess androgens are detrimental to repair. We have previously shown that androgens delay wound healing, reduce re-epithelialisation, and prolong bleeding in mice undergoing simulated menses2. In other tissues, such as the skin, androgens regulate macrophage function during repair by altering their turnover and phenotype but it is not known if this occurs in the endometrium.
We aim to understand how macrophages are regulated in the endometrium, how their function may be altered in response to androgens, and how this can impact on women's reproductive health.

We use fate-mapping techniques, transcriptomics analysis, multiparameter flow cytometry and immunohistochemistry in order to characterise cell populations that are required for endometrial repair. We combine these approaches with pharmacological and genetic modulation of androgen action in order to understand how androgens affect repair.

I obtained my undergraduate degree in Pharmacology from the University of Edinburgh before undertaking a PhD at the MRC Human Reproductive Sciences Unit with Professor Philippa Saunders examining the role of estrogen signalling in the endometrium. I undertook postdoctoral training at the MRC Centre for Reproductive Health and then the MRC Centre for Inflammation Research where I discovered that local hormone signalling within the endometrium was required for establishment of pregnancy in women.
In 2013, I published a landmark study which was the first to identify that local biosynthesis of oestrogens occurs within the endometrium during early pregnancy remodelling (Gibson et al 2013) and went on to show that this directly affects the function of uterine natural killer cells by increasing cell migration and promoting vascular remodelling (Gibson et al 2015). These studies led to a paradigm shift in our understanding of early pregnancy remodelling and specifically how temporal and spatial changes that are required for pregnancy are controlled by local hormone action. I went on to identify that androgens also play a key role regulating endometrial receptivity (Gibson et al 2016) and, in further studies, found that the decline in circulating androgen precursors that occurs in older women may contribute to lower fertility (Gibson et al 2018). These studies attracted significant media attention (The Times, The Sun, The Daily Mail) and were recognised by the award of the Society for Endocrinology Early Career Lecture Prize (2018) and the Society for Reproduction and Fertility New Investigator Award 2020.
In July 2020, I was awarded a Royal Society and Wellcome Trust Sir Henry Dale Fellowship to establish my own laboratory in Edinburgh investigating the impact of androgens on macrophage function during endometrial tissue repair.
