Document Summary
We will follow the ductus deferens as it becomes associated with the accessory organs to help produce semen (the fluid that forms most of the volume of ejaculate, which is only 5% sperm) Spermatic cord includes everything in the red box (including the autonomic nerve fibres) Recall pampiniform vein isn"t a singular vein; it draws heat away from artery. Purpleish structure in the middle is the prostate. Ampulla receives contributions from the seminal vesicles to form the ejaculatory duct. Left img: looking at it from behind; 2 ureters are coming in and penetrating into the post surf of. We see in green the dd, coming around the ureters and become expanded as the ampullae; dd. These are all bilateral so there are 2 of each; 2 ejac ducts seminal vesicles never store sperm (it"s a misnomer; it only secretes fluids; in earthworms it stores sperm though) Bladder on the top of this image with ius.
