The ovaries are two small, almond-shaped organs that are located on either side of the uterus. They are an essential part of the female reproductive system and produce eggs (ova) as well as the hormones estrogen and progesterone.

The size of the ovaries can vary somewhat, but they are typically about 3 centimeters long and 2 centimeters wide.

What is the Normal Size of an Ovary?

The ovaries are a woman’s reproductive organs that store eggs and produce hormones. The average ovary size is about 3 cm long and 2 cm wide. However, the size of the ovaries can vary depending on a woman’s age and health.


The size of your ovaries will change throughout your life. They’ll be biggest just before you start puberty, and they’ll shrink during menopause.

In general, older women have smaller ovaries than younger women. But there’s no one “normal” size. The average ovary is about the size of an almond, but it can range from the size of a pea to that of a small plum.

Body Mass Index

Body Mass Index, or BMI, is a calculation based on both height and weight. It’s a general assessment of whether someone is within a healthy weight range for their height. To calculate your BMI, you can use our BMI calculator.

There isn’t an exact normal size for an ovary, but in general, they’re about the size of an almond. The left ovary is usually slightly larger than the right.


There is no definitive answer to this question as there is significant variation in the size of ovaries among women of different races. In general, however, the average ovary is about the size of an almond and weighs approximately 3 grams.

Factors That Affect the Size of an Ovary

The size of an ovary can be affected by various factors, including age, health, and hormone levels. For example, ovaries tend to be smaller in size before puberty, during pregnancy, and after menopause. Additionally, conditions such as PCOS can also cause the ovaries to become enlarged.

Hormonal Contraceptives

There are many factors that affect the size of an ovary. One major factor is the use of hormonal contraceptives. Birth control pills, injections, implants, and intrauterine devices (IUDs) all release hormones that can alter the size of the ovaries. In most cases, the ovaries will shrunken in size when hormones are present. The length of time that hormonal contraceptives are used also affects ovarian size. In general, the longer a woman uses hormonal contraception, the more her ovaries will shrink in size.

Other factors that can affect ovarian size include age, weight, smoking status, and whether a woman has ever been pregnant. Ovarian size typically decreases with age and increases with weight. smokers tend to have smaller ovaries than nonsmokers, and women who have never been pregnant tend to have smaller ovaries than women who have had at least one pregnancy.


Pregnancy is often associated with an increase in the size of the ovaries. This is due to the increased production of estrogen and progesterone, which stimulate the growth of the egg-containing follicles in the ovaries. The ovaries typically return to their normal size after pregnancy.


One of the most common factors that affect the size of an ovary is menopause. Once a woman reaches menopause, her ovaries will gradually shrink in size. This process is known as involution and typically begins around the age of 51. During involution, the ovaries lose their ability to produce eggs and hormone levels decline. As a result, the ovaries will become smaller and may even shrink to the point where they cannot be seen on an ultrasound. In some cases, the ovaries may even disappear altogether.

There are other factors that can affect the size of an ovary besides menopause. For example, if a woman has had her ovaries removed surgically (known as oophorectomy), then she will no longer have any ovaries and they will not be able to be seen on an ultrasound. Other conditions such as ovarian cancer or polycystic ovarian syndrome (PCOS) can also cause the ovaries to enlargen and become misshapen. In these cases, it is also unlikely that the ovaries will be able to be seen clearly on an ultrasound.

When to Worry About the Size of Your Ovaries

Ovaries are almond-shaped reproductive organs that are located in the pelvis. They are an essential part of the female reproductive system and produce eggs that can be fertilized by sperm to create life. The ovaries also produce hormones, such as estrogen and progesterone, which play a vital role in regulating a woman’s menstrual cycle.

The size of your ovaries can fluctuate throughout your lifetime. In general, they will grow during puberty and then remain relatively stable until you reach menopause. After menopause, the ovaries will begin to shrink.

There is no “normal” size for an ovary, but there are certain measures that can indicate whether or not they are healthy. For example, a healthy ovary should be approximately the same size as a walnut. If they are much larger or smaller than this, it could be a sign of a problem.

Additionally, if you have any symptoms that seem unusual or concerning, it’s important to consult with your doctor to rule out any possible underlying health issues. Some common symptoms that may warrant further investigation include:

-Abnormal bleeding or spotting
-Pelvic pain or pressure
-Enlarged abdomen
-Urinary problems
-Nausea or vomiting


After ovulation, the now empty follicle is called a corpus luteum. The corpus luteum secretes the hormone progesterone, which helps prepare the uterus for possible pregnancy. If pregnancy does not occur, the corpus luteum disintegrates and progesterone levels drop, triggering menstruation.
