The female ovaries are generally developed about 100 days after fertilization. The male testis do not descend into the scrotum until the ninth month of development although this sometimes occurs after birth.

Gonads. Male sex gland - Testis. Female sex gland - Ovary.
Flowing plants, also known as angiosperms use flowers for repodution purposes. They consist of a male reproductive organ called anther and a female reproductive system called ovary.
The endocrine system controls the functioning of the reproductive system. The responsible endocrine glands are known as the gonads. The gonads secrete sex hormones, which are responsible for sexual development, and the associated growth spurts in the body. They are also responsible for the development of secondary sexual characteristics. Other hormones also affect the functioning of the reproductive system. These include the gonadotropin releaseing hormones from the hypothalamus, the pituitary hormones like prolactin, insulin from the pancreas, and thyroxine from the thyroid.
reproductive modes and structures
They are called gonads. A male gonad is the testes, they produce sperm. A female gonad is the ovaries, they produce eggs.
Vegetative growth involves roots and shoots but not reproductive structures and occurs in most plants.
because it conveys semen during ejaculation
The testes (plural) otherwise known as the testicles.
In plants, the flowers. In animals, the genitals/gonads.testes and ovaries
Like the ovaries to which they are homologous, testes are components of both the reproductive system (being gonads) and the endocrine system (being endocrine glands). The respective functions of the testes are:producing sperm (spermatozoa)producing male sex hormones of which testosterone is the best-known
The rectangular body sections of a tapeworm are known as proglottids. Each proglottid contains both male and female reproductive structures.
