When it comes to fertility, women may hear about hormone levels, egg quality, and uterine health. But one of the questions that I pretty often hear is — “Does the size of my ovaries affect my ability to conceive?” The short answer is — yeah, a little, but there are other factors at play too. Let’s explore what ovary size really means, its role in fertility, and when you should consider medical advice.
What Is a Normal Size of the Ovary?
The ovaries are little almond-shaped glands, situated one on each side of the uterus. Their primary role is to release eggs (ovum) and produce reproductive hormones such as estrogen and progesterone.
Average ovary size among women of reproductive age:
- Length: 2.5 to 5 cm
- Width: 1.5 to 3 cm
- Thickness: 0.6 to 2.5 cm
- Volume: Between 5 – 10 cubic centimeters (cc)
But ovary size can do some slight fluctuating based on age, hormonal health, and anatomy.
What Effect Does Ovary Size Have on Fertility?
Ovary size isn’t everything when it comes to fertility, but this organ can be telling when it comes to a woman’s reproductive potential. Here’s how:
- Small Ovaries (Decreased Volume)
Cause: Very common among women with low ovarian reserve or who are nearing menopause. It also can be a result of certain medical treatments, such as chemotherapy.
Effect on Fertility: Smaller ovaries may also contain fewer antral follicles, resulting in low egg reserve and low number of eggs available for fertilization. But quality of egg matters more than quantity, particularly with fertility treatments such as IVF (Ovarian Induction).
- Normal Ovaries
Cause: Excellent hormonal balance and ovarian reserve.
Effect on Fertility: Ideally, ovaries of normal size and well perfused and with healthy follicles are needed to achieve spontaneous pregnancy or in ART(Assisted Reproductive Technology) procedures.
- Enlarged Ovaries
Cause: Factors such as Polycystic Ovary Syndrome (PCOS) or ovarian cysts.
Effect on Fertility: Cysts can cause irregular ovulation, as well as enlarged ovaries with numerous small follicles. PCOS can have the effect of making pregnancy more difficult, but with treatment, lots of women with PCOS are able to get pregnant.
But What’s More Important Than Ovary Size?
Although size of the ovaries provides some clues, there are a lot of other factors that go into fertility such as:
-
Ovarian Reserve: AMH‐based on AMH (Anti‐Müllerian Hormone) and AFC (Antral Follicle Count) on ultrasound.
-
Egg Quality: Easier eggs: Younger women generally have healthier eggs. Pregnancy chances are still high with less eggs, assuming they’re of good quality.
-
Ovulation Function: Healthy, natural ovulation is a necessary part of the conception process.
-
Hormonal Balance: FSH, LH, estradiol and progesterone are important for the menstrual cycle and fertility.
-
Other Factors: There is also the quality of the partner’s sperm, the health of the tubes and the lining of the uterus and lifestyle issues.
How Is Ovary Size Checked?
Ovarian volume measurement is generally performed by transvaginal ultrasound in the process of infertility examination. Here’s how this aids fertility doctors:
- Measure the ovarian volume
- Count the number of antral follicles (tiny fluid-filled sacs that contain immature eggs)
- Identify cysts or abnormalities (such as PCOS)
Do Women With Small Ovaries or Enlarged Ovaries Get Pregnant?
Yes! Plenty of women with small or large ovaries conceive spontaneously or with medical help. The answer is individualized testing and right fertility treatment.
For Small Ovaries or Low AMH: There are options such as IVF, ICSI, or egg stimulation or Ovarian Induction protocols that may help to achieve mature and healthy eggs.
For Enlarged Ovaries (PCOS): Treatments such as ovulation induction, lifestyle modifications and sometimes IVF achieve good results.
The line of treatment is based on complete reproductive profile of the person.
When Do You Need A Fertility Specialist Now?
If you haven’t had any success when you’ve tried for 6 to 12 months, or if you have a diagnosis like PCOS or diminished ovarian reserve, the best course of action is to visit a fertility specialist.
Early consultant appointments could prevent needless treatment delays and associate particularly with women 30 and older.
