This organ is the subject of the D’Amico risk classification, and it is reduced in size using steam in Rezum Water Vapor Therapy. Patrick C. Walsh developed “radical” techniques to remove this organ using an incision in either (-5[1])the abdomen or perineum. (15[1]-5[1])This organ is studied using the PC3, D·U·145, (15[3])and L·N·C·a·P cell lines. (-5[1])A disease (15[1])of this organ is scored from one (15[1])to five on the (-5[1])(*) Gleason (10[1])scale, (10[7]-5[1])and (10[1])is (10[1])similar to a namesake (10[1])type of benign hyperplasia. (10[2]-5[1])Secretions from this (10[1])organ include (-5[1])zinc and kallikrein-3, (10[1])its namesake (-5[1])“specific (10[1])antigen,” (10[1])and make up (10[1])about 30% of semen. The back wall (10[1])of this accessory (10[3])gland (10[1])is (10[1])felt for enlargement (10[5])with a gloved, (10[4])lubricated (10[4])finger (10[5])in a (10[1])digital rectal (10[3])exam. For 10 points, name this walnut-shaped reproductive gland, (10[1])the site (-5[1])of the most common cancer in males. (10[2])■END■ (10[6]0[1])
