Funded Activity Summary

Historically the steroid sex hormones - oestrogens and androgens - have been regarded as female- and male- specific sex hormones, respectively. Oestrogens are produced by the ovary and regulate female-specific processes such as ovulation and development of female sexual characteristics, whereas androgens are produced by the testis and regulate male-specific functions. However it is now clear that the distinction between oestrogen and androgen is not a sharp one. For example, we now know that oestrogens are produced within the testis and play a very important role in male fertility. Human males patients who are unable to synthesise oestrogens are infertile. Similarly, mice that cannot produce oestrogens are also infertile, due to a defect in sperm production. Oestrogens are therefore critical for normal male fertility, and reduced oestrogen production within the testis may be a significant cause of infertility which would be easily treatable in the clinic. The protein LRH-1 regulates oestrogen production in other tissues. This proposal aims to identify the role of LRH-1 in testicular oestrogen production by identifiying the genes regulated by LRH-1 and the proteins that interact with it in the testis. We also aim to study the structure of these proteins in infertile men. These studies will define new genes associated with male infertility and may lead to the development of more effective treatments for this common condition.
