Introduction

My expertise and training focused on male reproductive pathology, endocrinology and toxicology. Specific interests include testicular growth and development, spermatogonial stem cell regulation, estrogen regulation of the male reproductive tract and the function of cilia in reproduction. In an effort to better understand and teach spermatogenesis and to use stages in testicular pathology and toxicology, we produced STAGES™ computer software for tracking each cell through the cycle. Major studies in recent years have focused on the presence and function of estrogen receptors in the male reproductive tract and Sertoli cell regulation of stem cell self-renewal. Efferent ductules of the male were found to express estrogen receptors 3.5-fold greater than female tissue. Using the ER-alpha knockout mouse and antiestrogen treatment models, the first known physiological function for estrogen in the male reproductive tract was demonstrated to be the regulation of fluid reabsorption in the efferent ductules. Current collaborative studies are examining the role of membrane estrogen receptors, as well as the function of motile and primary cilia in the physiology of this unique tissue. As Professor Emeritus, I have continued collaborative projects in several laboratories associated with histopathological effects of gene disruption on spermatogenesis and efferent ductule structure and function, as well as epididymal pathology.

Motile cilia of the male reproductive system require miR-34/miR-449 for development and function to generate luminal turbulence.

Proc Natl Acad Sci U S A 2019 02 18;116(9):3584-3593. Epub 2019 Jan 18.

Department of Physiology and Cell Biology, University of Nevada, Reno School of Medicine, Reno, NV 89557;

Cilia are cell-surface, microtubule-based organelles that project into extracellular space. Motile cilia are conserved throughout eukaryotes, and their beat induces the flow of fluid, relative to cell surfaces. In mammals, the coordinated beat of motile cilia provides highly specialized functions associated with the movement of luminal contents, as seen with metachronal waves transporting mucus in the respiratory tract. Motile cilia are also present in the male and female reproductive tracts. In the female, wave-like motions of oviductal cilia transport oocytes and embryos toward the uterus. A similar function has been assumed for motile cilia in efferent ductules of the male-i.e., to transport immotile sperm from rete testis into the epididymis. However, we report here that efferent ductal cilia in the male do not display a uniform wave-like beat to transport sperm solely in one direction, but rather exert a centripetal force on luminal fluids through whip-like beating with continual changes in direction, generating turbulence, which maintains immotile spermatozoa in suspension within the lumen. Genetic ablation of two miRNA clusters ( and ) led to failure in multiciliogenesis in murine efferent ductules due to dysregulation of numerous genes, and this mouse model allowed us to demonstrate that loss of efferent duct motile cilia causes sperm aggregation and agglutination, luminal obstruction, and sperm granulomas, which, in turn, induce back-pressure atrophy of the testis and ultimately male infertility.
