Project title: The Measurement of Profile Area of the Cytoplasmic Droplet (CD) of Rat Sperm in the Testis and Epididymis
Project description (50-100 words suggested): The CD is a small portion of the cytoplasm that is retained along the midpiece of the flagellum of sperm. The focus of this project is to investigate quantitatively the change in size of the Hermes body as sperm are transported from the seminiferous tubule to the epididymis. At the last step of germ cell development, step 19 spermatids, these cells are released into the lumen of the seminiferous tubules to then enter the epididymal duct. As sperm move through the epididymis, they become fertile in the initial segment and then are stored in the cauda.
The measurement of diameter of the CD will be performed by using ImageJ software on immunohistochemical images obtained from staining the CD of three different rats with 3 different antibodies and of sperm at step 19, initial segment and cauda regions. The standard statistical analysis is necessary to show the signficance level of any difference in diameter. We hypothesize that the CD will increase in size from step 19 to the initial segment and then decrease as they reach the cauda region.
