Background / introduction
Follicular fluid (FF) surrounds the granulosa cell-oocyte complex and is one of the mediating factors in the communication between the cells within the follicle. Literature reveals that human FF and its components are key factors to the success of natural fertilization. Among other substances, FF consists of multiple cytokines and immune cells, including interleukin 6 (IL6), IL12, sHLA-G, macrophages, NK cells, and lymphocytes. Together, these cells and cytokines might influence the oocyte-granulosa-cell complex. Altered balances of immune content might be involved in changes on folliculogenesis, oocyte maturation, oocyte quality, and ovulation. Furthermore, these altered balances are possibly involved in infertility associated with immune mediated diseases such as endometriosis.
Research question / problem definition
The aim of this research is to elaborate on the function and contents of FF and its immunological profile in patients with endometriosis compared to matched controls
Prospective follicle fluid collection and processing. Flow cytometry to identify T cell subsets and regulatory T cells and Luminex cytokine profiling.
