Macroscopic Anatomy

In shape the prostate is usually described as a flattened cone with the base upwards,the apex downwards and four sides with rounded corners.

The four sides are known as the front, back and lower-lateral faces. A normal prostate is 4 cm in length, 3 cm at the cross-section and 2.5 cm at the antero-posterior section. Weight ranges from 15 to 20 gr.

Lodged in the pelvis, the prostate adheres strongly to the bladder neck and is fixed to the pelvic bones (mainly anteriorly to the pubis) by many ligaments and other supporting structures e.g. the urogenital diaphragm
