Infertility is a complex and devastating disease and although progress has been made, we still struggle to identify, diagnose and treat this condition. Infertility affects about one in six Australian couples of reproductive age. The inability to conceive has detrimental impacts on patients’ self-worth, mental health, financial status, and their relationships. It is estimated that about 40% of cases it is attributed to a male factor, 40% to a female factor and the remaining to a combination of both. While a genetic cause is often suspected, the molecular basis of infertility in humans remain poorly understood.
We have shown that loss of the prorenin receptor in mouse somatic cells of the gonads, testes and ovaries, results in both male and female infertility. The prorenin receptor is best known for its role in the renin-angiotensin system (RAS). However, recent research showed that it plays multiple roles independent of pro/renin binding. Using mouse as model system, this project characterizes its role in fertility and will therefore uncover critical mechanisms underlying testicular and ovarian development and disease.
