About the Ovary

Meaning
The ovaries are organs in the female reproductive system and endocrine glands in the endocrine system.
About Ovaries in the Female Reproductive System
- The ovaries are where the ova are stored.
- During the menstrual cycle follicle stimulating hormone causes a follicle in the ovary grow and a single ovum to mature.
- Luteinizing Hormone causes the ovum to be released from the follicle.
About Ovaries as Endocrine Glands
- Ovaries secrete oestrogen which causes the expression of female characteristics during puberty including the widening of the hips, breast growth and the initiation of the menstrual cycle.
