Introduction to Reproductive Disorders of Dogs

The reproductive system is the group of organs that produce offspring. In both males and females, the reproductive system is composed of primary sex organs and primary regulatory centers. The primary sex organs are the testes and genital tract in males and the ovaries, fallopian tubes, and uterus in females. The primary regulatory centers are in the brain (the pituitary gland and hypothalamus). They control the production of hormones that in turn influence the function of the primary sex organs.
