Bone Marrow
The bone marrow is the primary organ responsible for producing all types of blood cells, including red blood cells, white blood cells, and platelets. It is located within the cavities of bones.
The liver stops producing blood cells in the second trimester of fetal development. After birth, the bone marrow takes over as the primary site of blood cell production throughout an individual's life.
The five primary white blood cells are neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each plays a role in the immune system, such as fighting infections (neutrophils), producing antibodies (lymphocytes), and controlling allergic reactions (eosinophils).
Stem cells that replace old blood cells are primarily found in the bone marrow of adults. These adult stem cells are called hematopoietic stem cells and they are responsible for producing all types of blood cells, including red blood cells, white blood cells, and platelets.
There are more than two if you were to disect the testes. Two than come to mind are sperm cells and blood cells but there are also other tissue cells such as skin cells. Perhaps you need to rephrase the question.

In adults they are mostly produced in the bone marrow. There are situations where they can be produced elsewhere.
Blood cells.

Blood cells (Steam cells) start producing new red blood cells and white blood cells.
White blood cells
White blood cells are the body's primary defense against infections. They detect and eliminate pathogens like bacteria, viruses, and other harmful substances. White blood cells also help in the body's immune response by producing antibodies and activating other immune cells.
Because that's where blood cells grows.
The primary function of red blood cells (scientifically know as erythrocytes) is to transport oxygen to wherever its destination may be.
The two primary cells in blood are the red blood cells (erythrocytes) and the white blood cells (Leukocytes). Platelets (Thrombocytes) are a third kind of blood cell.
