The negative correlation between the thickness of the lamina propria and Johnsen's score count in individual seminiferous tubules was observed and the tubules with thin lamina propria indicated almost complete spermatogenesis. It is suggested that the thin lamina propria may be one of the good indicators of complete spermatogenesis.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009092	Mucous Membrane	An EPITHELIUM with MUCUS-secreting cells, such as GOBLET CELLS. It forms the lining of many body cavities, such as the DIGESTIVE TRACT, the RESPIRATORY TRACT, and the reproductive tract. Mucosa, rich in blood and lymph vessels, comprises an inner epithelium, a middle layer (lamina propria) of loose CONNECTIVE TISSUE, and an outer layer (muscularis mucosae) of SMOOTH MUSCLE CELLS that separates the mucosa from submucosa.
