What are Ejaculatory Ducts?
The ejaculatory ducts are two hollow tubes, each formed by the union of the ampulla of the vas deferens and the excretory duct of a seminal vesicle. The ducts, which open into the urethra about halfway through the prostate gland, function to mix the sperm stored in the ampulla with fluids secreted by the seminal vesicles (think of a blender) and to transport these substances to the prostate. What is the Prostate Gland? The prostate glands’ main function is to store and secrete an alkaline (pH7.29) fluid (filled with proteins and hormones) that usually appears thin, white and milky. The reason for the alkalinity of prostate fluid is that it helps neutralize the acidity of the vaginal tract, prolonging the lifespan of sperm. Without the protective fluid provided by the prostate, very few sperm cells would ever reach the egg. The prostatic fluid is released in the first ejaculate fractions together with most of the sperm, making up 25-30% of the volume of the semen along with sperm and se
