Question

Name the hormones secreted from the testes and the ovary and also mention their functions.

Answer 1

Hormones secreted from the testes:

1. The hormone secreted by the testes is testosterone.
2. Testosterone is important for the physical changes that happen during male puberty, such as the development of the penis and testes.
3. Testosterone also acts on cells in the testes to make sperm. LH( Luteinizing hormone) is needed for the Leydig cells in the testes to make testosterone, the male sex hormone.
4. Testosterone and FSH(Follicle Stimulating Hormone) from the pituitary gland then act together on the seminiferous tubules (sperm-producing tubes) in the testes to make sperm.

Hormones secreted from the ovary:

1. Ovaries secrete progesterone and estrogen.
2. Estrogen: This hormone is produced by the granulosa cells of the ovarian follicle. It controls changes in the follicular phase which includes the growth of the new ovarian follicle and uterine wall.
3. Progesterone: This hormone is secreted by the corpus luteum and helps in maintaining the pregnancy.
