The prostate is inverted so that its apex is inferior and its base is superior around the bladder neck anterior to the rectum.
The Male urethra
This is about 20 cm long, It extend from the neck of the bladder through the prostate gland the length of the penis and at the distal end of the penis
It convey urine from the bladder and spermatozoa, seminal fluid and prostatic fluid during sexual intercourse
The Penis is composed of three cylindrical masses of erectile muscle enclosed in separate fibrous covering and held together by a covering of skin, A Flap of movable and retractable skin, the foreskin or prepuse, covers the glands
