What are called gonads?

What are called gonads?

The gonads, the primary reproductive organs, are the testes in the male and the ovaries in the female. These organs are responsible for producing the sperm and ova, but they also secrete hormones and are considered to be endocrine glands.

What is the main function of gonads?

The two major functions of the gonads in the adult are steroid hormone production and gametogenesis. Reproductive hormones are also pivotal in sexual differentiation, fetal development, growth and sexual maturation.

What is gonad in fish?

What are the names of the male and female gonads?

In males the gonads are called testes; the gonads in females are called ovaries. (see ovary; testis). The gonads in some lower invertebrate groups (e.g., hydrozoans) are temporary organs; in higher forms they are permanent. In some invertebrates, such as oligochaete worms and leeches, both male and female gonads exist in a single organism.
