7 Important Factors That Lead to Change in the Size of the Ovary

As a girl grows, the ovary grows along with her. Before a girl attains puberty, the ovaries are smaller than the average size. It starts growing once she reaches puberty and is the largest when she is pregnant. When menopause starts crawling after 35 years, lesser eggs are fertilized, and the size of the ovaries shrinks to as low as 2 cm.

2. Ovarian Disorder

Ovarian disorders are majorly caused by cysts – Polycystic Ovarian Syndrome (PCOS). The cysts are pockets filled with fluid on the surface of the ovary. This is a common disorder faced by many women. They are neither painful nor harmful. Many women do not even know they have a cyst. However, these cysts might be dangerous in the following situations.

3. Functional Cysts

When the hormones required for the release of eggs from the follicle are secreted in a smaller amount, multiple cysts may form on the surface of the ovaries. This can lead to infertility and other serious diseases, including diabetes and heart problems. These are generally painless and tend to disappear on their own after a few menstrual cycles.

4. Dermoid Cyst

They are commonly known as “teratomas.” They are formed from embryonic cells. Hence, they may develop specific tissues on the ovary like skin, hair, teeth, etc. They are caused when the skin structures are confined during fetal development.
