However, a number of other factors can cause diminished ovarian reserve. These include:. However, those with the condition might experience any of the following symptoms:.
Early diagnosis means that you have a better chance of successful treatment. Both of these hormones play an important role in menstruation and reproduction. According to the Center for Reproductive Health, 33 percent of their patients with diminished ovarian reserve are able to get pregnant with their own eggs after receiving treatment.
However, the center emphasizes that early diagnosis is important, as it gives you a better chance of conceiving. One of the most common treatments for diminished ovarian reserve is supplements like dehydroepiandrosterone DHEA , a mild androgen. DHEA supplements can increase fertility. One study looked at 33 participants who had diminished ovarian reserves and monitored how DHEA affected their success at in vitro fertilization IVF. While Another study looked at 77 participants with diminished ovarian reserve, and found that those who took DHEA were significantly more likely to get pregnant spontaneously — that is, without additional medical intervention.
However, a review of studies notes that more research is needed before we can confidently say that DHEA improves fertility levels. Other than DHEA supplements, there are a few ways to get pregnant if you have this condition. Your doctor might even suggest trying IVF immediately. Another option is using donor eggs to get pregnant. A primordial follicle is just 25 micro meters—that's 0. It is impossible to see with the naked eye, let alone on an ultrasound.
As long as they continue to survive and graduate to the next stage, they grow larger and larger. One of those stages is the tertiary stage. During this time, the follicle gains a fluid-filled cavity known as the antrum. Follicles with an antrum are referred to as antral follicles and measure between 2 and 10 mm in diameter.
For some perspective, an antrum follicle that is now 5 mm is times bigger than it was as a primordial follicle. Antrum follicles are visible with ultrasound.
Research has found that the number of active antrum follicles on the ovaries correlates to the potential number of eggs left. Antral follicles produce higher levels of a hormone known as anti-mullerian hormone AMH , which circulates in the blood. Measuring AMH levels via blood testing is another way to evaluate ovarian reserves. An antral follicle count is done via transvaginal ultrasound, sometimes between cycle day 2 and 5. The test may be done as part of a fertility workup. Or, it may be ordered before a fertility treatment cycle.
During this test, the ultrasound technician looks at each ovary and counts the number of follicles measuring between 2 and 10 mm. It is normal for your ovarian reserves to decrease as you age.
Still, an antral follicle count of 3 to 6 is considered low. One classic study conducted antral follicle counts in women with proven fertility most studies on AFC were done on infertile women. To be included in this study, the women had to:. But it does mean your ovaries may not respond to fertility drugs as well as a woman with better ovarian reserves.
The skill of the ultrasound technician and the ultrasound equipment itself can affect the results. If one test shows a poor result, consider getting a second opinion. Women with a very low antral follicle count before age 40 may be diagnosed with primary ovarian insufficiency, also known as premature ovarian failure.
An unusually high antral follicle count may indicate polycystic ovarian syndrome PCOS. Your menstrual cycle is split into two primary parts: the follicular phase and the luteal phase. During the follicular stage, follicles in the tertiary stage of development are recruited and begin a process that will eventually lead to ovulation. While several follicles start out in this race, only one or two will reach full maturity and release an egg.
The follicles themselves are responsible for:. The follicular phase of your cycle begins on the first day of your period. Menstruation is the body's release of the top layer endometrial tissue, which was built up in anticipation of pregnancy. At the end of your period, the uterine lining will be thin. The lining will grow and become thicker again after ovulation. But before that occurs, during your period, your ovaries are preparing the next egg for ovulation.
Between five and six follicles will start to grow in your ovary. The hormone FSH—follicle stimulating hormone—is produced and released by the pituitary gland. It's this hormone that triggers the follicles to mature.
As the follicles increase in size, they release more estrogen. Higher levels of estrogen signal the pituitary gland to slow down the production of FSH. Even though you started with five or six follicles, just one and sometimes two will make it to maturity.
Lower levels of FSH cause the smaller follicles to grow more slowly or even stop growing, while the bigger follicle continues its steady development. Eventually, one follicle becomes the dominant follicle; the others stop growing and disintegrate.
When the follicle reaches close to its maximum size, it releases even more estrogen. Very high levels of estrogen trigger the pituitary gland to produce and release LH, or luteinizing hormone.
This pushes the follicle to complete its last stages of development. Finally, the follicle will burst open and release an egg.
This is the moment of ovulation. You might think that follicular development starts and ends during the follicular phase of the menstrual cycle, but that is not the case. The full follicular lifecycle begins before a person is even born, when the ovaries are first developed in a growing fetus. Overall, while follicle counts are useful tools in the IVF process, they are not the end of the story in regards to IVF success.
A woman with a high antral follicle count may not end up with viable eggs due to issues with overstimulation or a secondary complicating condition, while a woman with a low antral follicle count could end up with a successful cycle, because while more eggs are better, just one can sometimes be enough.
Choosing whether or not to move forward with an IVF cycle based on the number of antral or mature follicles seen on the ultrasound is a decision that only you and your doctor can make.
There are many fertility tests for women which can help give you a picture of your reproductive health and status, and some are covered by insurance because they are diagnostic.
Information is power, and scheduling a fertility checkup before you plan to start trying for a baby is one of the best things you can do for your reproductive future. See related posts.

Wendy Burch is an Emmy-winning journalist, acclaimed professional writer, and inspiring motivational speaker. What are follicles and why are they important for IVF? There are two stages of follicles which are important in the IVF process: Antral Follicles: Antral follicles are small, immature follicles at a stage where they are 2 to 9mm long: large enough to be seen with a transvaginal ultrasound at the beginning of a menstrual cycle. A mature and viable follicle which is ready to release an egg should ideally be close to 20mm long.
How many antral follicles should there be for a good response to IVF? How many mature follicles should there be before triggering ovulation for IVF? Ideally, fertility clinics would like to see 4 mature follicles before the trigger shot.
