I am a reproductive biologist with a particular interest in the impact that specific nutrients have on the growth and development of the ovarian follicle. It could be hypothesized that the centre of a large preovulatory follicle, where the oocyte resides, may be relatively hypoxic because the oocyte and the several layers of surrounding granulosa cells are avascular.
To investigate oxygen concentration in individual ovarian follicles in vivo we have innovated and adapted tools first designed for research in oncology. Surprisingly we found that the follicles fell into one of three groups with respect to how much oxygen was measured at their centre: about 50 % were anoxic (that is, almost no oxygen was detected), 25 % had concentrations of oxygen predicted to be normal of most tissues in the body and the remainder had oxygen concentrations significantly higher than normal. Our next task is to determine which of these three groups of follicles gives rise to the oocytes with the best developmental competency. The outcome of this research could be used to inform and improve current IVF practices.
In investigating how nutrition can interact with the reproductive axis I became interested in the hypothalamic role of the neuropeptide, MCH, and this in turn has led to work investigating the roles of the melanocortins on reproductive function. We are currently characterizing the expression and distribution of each of the members of the melanocortin system in reproductive tissues at different ages and in different physiological states before commencing studies to determine their roles in modulating reproductive function.
