Testing facilities that engage in animal testing dispose of both animals and dangerous chemicals, food waste, and a variety of supplies used during the testing process. Not to mention, animal testing has a heavy impact on water and air quality. Additionally, animal testing is cruel and ineffective. Animals don't get many of the diseases that humans do. For example, major types of heart disease, many types of cancer, HIV, Parkinson's disease, and schizophrenia. 100 million animals are killed each year due to animal testing.
The testes are contained in the scrotum and are composed of dense connective tissue containing around three hundred internal compartments called lobules. Each of these lobules contains a number of coiled, tiny tubules where the sperm are produced. Testosterone is produced in cells located in between the lobules
