The prostate is a glandular organ that is normally about 3 cm long (slightly more than 1 inch) and lies at the neck of the bladder and in front of the rectum. The prostate produces a thin, milky fluid that is added to the sperm at the time of ejaculation. It surrounds the urethra, which is a tubular structure that carries sperm and urine out of the penis, therefore prostate diseases often affect urination, ejaculation, and rarely defecation.

Anaemia is a condition in which the number of red blood cells or their oxygen-carrying capacity is insufficient to meet physiologic needs. Therefore anaemia may be due to low red cell mass or increased plasma volume.
Anemia is actually a sign of a disease process rather than a disease itself. It is usually classified as either chronic or acute.
