Our group is studying the pathophysiological mechanisms of genitourinary dysfunction in men and women to help discover new therapeutic strategies to treat and prevent sexual and urinary dysfunction. PDE5 inhibitors, such as Viagra or Cialis, have been successful at treating erectile dysfunction in men; however, they do not cure the underlying disease and treatments for female sexual dysfunction are lacking.
The vasculature supplying the genital organs, the internal pudendal arteries, undergoes pathological vascular remodeling, fibrosis and endothelial dysfunction prior to other similarly sized systemic arteries. We are characterizing the unique properties of this vascular bed in models of aging, cardiovascular disease, diabetes, obesity and radiation to find treatments that can improve both sexual dysfunction and cardiovascular disease. We are also interested in the role of neuronal dysfunction and degeneration of the pelvic ganglia and cavernous/pelvic nerves in neuropraxia, diabetic neuropathy and aging related to pelvic organ dysfunction.
Using integrative techniques, we can examine in vivo sexual and bladder function, ex vivo isolated smooth muscle reactivity, changes in molecular signaling pathways, and localization of these changes with histology. Our goals are to elucidate how the vasculature and nerves are affected in these models of disease, to prevent vascular dysfunction/neurodegeneration and promote vascular health and neuroregeneration.
