The Siegfried Lab
We go nuts for gonads
At the Siegfried laboratory we investigate genetic regulation underlying development of the gonad. How do germ cells develop to form functional gametes and how are these differences between the sexes manifested during development? Answering these questions helps us uncover the underlying developmental processes that are essential for fertility and reproduction
Gonadal Sex Determination and Differentiation
How is sex determined and how does each gonad control differentiation into distinct cell types?
Germ Line Maintenance
How does the testis continuously produce a new supply of sperm in a controlled fashion to maintain fertility throughout life?
Telomere regulation of Meiosis
How does telomere maintenance affect fertility and meiosis?
