In farm animals, gonads are organs associated with reproduction. Gonads are the organs responsible for producing gametes (sperm in males and eggs in females), which are needed for sexual reproduction. In males, the gonads are called testes and they produce sperm. In females, the gonads are called ovaries and they produce eggs. These gametes are necessary for the fertilization of eggs and the production of offspring. Therefore, the gonads are crucial organs in the process of reproduction in farm animals.
