    4. We provide quantitative evidence that claudin-11 contributes significantly to Sertoli cell tight junction function in vitro. Interestingly, occludin, which is hormonally regulated but not implicated in infertility until late adulthood, is also a significant contributor to barrier function. PMID: 26585695
