When trying to conceive, there are numerous factors to consider beyond the basics like tracking basal body temperature and signs of ovulation. One crucial yet often overlooked aspect is the ovaries’ size. Though, the normal ovary size for pregnancy typically ranges from 1 to 3 cm in diameter. Along with the size of the ovaries, their health determines your fertility and chances of getting pregnant.
In this article, let’s explore the importance of ovary size for pregnancy, how it is determined, different ranges of ovary size and factors that can affect it.
Importance of Ovary Size For Pregnancy
Ovaries are oval-shaped small glands responsible for the production and release of eggs (also known as oocytes). They are located on both sides of the uterus and also regulate in producing the estrogen and progesterone hormones. Along with ovaries, the female reproductive system also includes multiple organs such as the vagina, uterus, fallopian tubes, and cervix. Refer to the below table to understand how the ovary size and function change throughout a woman’s life cycle, along with approximate size measurements at different stages:
| Phases | Ovary Size | Size Measurement | Function |
| Childhood | Small | Less than 1 cm | Ovaries are dormant (not active) |
| Puberty | Enlarges | 1-3 cm | Begin to produce hormones, initiate ovulation |
| Reproductive | Medium/Large | 2-5 cm | Regular ovulation, hormone production |
| Menopause | Decreases | Less than 1 cm | Ceases ovulation, declines hormone production |
Note: These are standard measurements which may vary from one woman to another based on several factors such as genetics, lifestyle and underlying health conditions.Â

Factors affecting the ovary size for pregnancy
The size and shape of your ovaries may change over time due to health conditions or ageing. Some of the common factors that can affect ovary size and shape include:

- Ovarian disorders – Ovarian disorders like Polycystic Ovarian Syndrome (PCOS) can cause the ovaries to enlarge due to abnormal growths and cyst formation.
- Hormonal changes – Your ovaries are responsible for the production and release of reproductive hormones including estrogen and progesterone. Certain hormonal changes and imbalances can affect the ovary size usually making them enlarged.

An irregular ovary size, whether smaller or larger than normal, can affect conception.
Small ovaries can impact follicular development, thereby, affecting the process of ovulation. On the other hand, the large ovary size does not imply a higher number of ovarian follicles, it can occur due to hormonal disorders and cystic tumours. Due to this, the ovary size can become as large as 15 cm in size.
Therefore, it is important to attain a normal ovary size for pregnancy. According to the experts, the normal ovary size is considered 3 cm x 2.5 cm x 1.5 cm (length x width x thickness).
