Ejaculatory Duct Obstruction Affects Seminal Vesicle Contractile Efficacy and Smooth Muscle Ultrastructure in a Rat Model

Figure 3

Representative ultrastructural micrographs of seminal vesicle smooth muscle cells of rats in the control group. (a) The smooth muscle cells in the muscle bundle were evenly distributed and neatly arranged, and their sarcolemma was intact. Dense bodies (Dbs) and dense plaques (Dps) are abundant and partly continuous. Small intercellular space and few collagen fibers (CFs) can be seen (magnification ×2.0 k). (b) Mitochondria (Mit) and a few rough endoplasmic reticulum (rER) with attached ribosomes can be seen around the nucleus (N) (magnification ×6.0 k).
