Out of all of those 1, follicles only one has the chance of reaching ovulation. During ovulation, a mature egg is released from the follicle. In addition to the follicles lost during your natural ovulatory cycle, there are additional outside forces like smoking that have the power to accelerate the loss of these follicles we review all of these damaging lifestyle factors in depth in the book, Everything Egg Freezing.
Because things like smoking accelerate the loss of follicles, it has the ability to accelerate aging in general, leading to cases of premature menopause. In short, a combination of nature and nurture can will define how many follicles are left in your ovaries now commonly referred to as your, "ovarian reserve" and how quickly they will disappear before you hit the inevitable mark of natural infertility, menopause.
DID YOU KNOW: You can carry and birth a baby even if you're going through menopause, you just have to use younger, quality eggs and have them fertilized and implanted whether they're your own younger eggs or those received from a donor.
Pretty wild, right? AFC is just one of the tests that can help paint a picture of how many follicles you have left in your ovaries - what's referred to as your "ovarian reserve.
It's important to note that even these biological markers are not completely accurate e. Yes, you will probably have a harder time conceiving, and if you do, you might have a higher chance of miscarriage, but it does not mean that you are completely infertile.
After proper counseling from your doctor, having information about your existing ovarian reserve can help you understand how many fertile years you may have left, which allows you to make a more informed decision about whether or not fertility treatment like egg freezing is right for you. AFC is used as a predictor of the number of mature or "dominant" follicles that are capable of being stimulated by the hormone injections taken before the egg retrieval takes place.
And because the more eggs you have retrieved is directly correlated with an increased chance of one of them becoming a healthy baby down the line , doctors can use the AFC to anticipate how many eggs you might get in an ovarian stimulation cycle for egg freezing or IVF.
In order to count the number of antral follicles in your ovaries at a given time, you'll need to make an appointment at your fertility clinic where your doctor or a trained technician will perform an ultrasound.
This isn't the kind of ultrasound that's often depicted on TV and movies with a wand on your tummy, this one is conducted transvaginally we'd rather explain this upfront in order to prevent any surprises! In this exam, a wand-like ultrasound device called a transducer is covered with a condom and lubrication and gently inserted into your vagina. This wand emits the ultrasound waves internally.
You will have a clear view of your follicles in images projected onto a screen in the exam room. This simple procedure is just one of several fertility tests that our Las Vegas fertility doctors will order to measure your ovarian reserve.
Combined with other test results , your antral follicle count helps your physician better understand whether assisted reproductive technology ART is needed, and if so, which fertility treatment is the best choice for you.
Antral follicles are tiny structures — just 2 mm to 10 mm wide — that can be viewed by ultrasound very early in your menstrual cycle. While multiple follicles may develop, typically only one egg-containing follicle reaches maturity and is released by your ovaries each month. Our Las Vegas fertility doctors will help you schedule your test for a specific day of your cycle, typically day three. At the imaging center, an ultrasound technician or your physician will insert a probe into your vagina, then will direct the probe as needed to examine and count the follicles on each of your ovaries.
If few antral follicles appear, a poorer response is expected and the IVF cycle could be cancelled to try for better results the following month. Contact us for more information on the Basal Antral Follicle Count and fertility testing in general. Fertility Testing. During IVF treatment , your doctor wants to stimulate your ovaries to mature several follicles. Anywhere between 8 and 15 follicles is considered an acceptable amount. During an egg retrieval, your doctor will aspirate the follicles with an ultrasound-guided needle.
Every follicle will not necessarily contain a quality egg. Follicle size and counts can be a source of stress.
A diagnosis of low ovarian reserves can be especially difficult to cope with. Your doctor may recommend IVF with an egg donor , a path that not all couples are able or willing to take. While follicle counts are an important indicator of fertility, remember that one number does not define you, or even absolutely predict your fertility future. If you're unsure what your follicle counts mean, talk to your doctor.
