Macerated Ovarian Reserve might sound scary, but please know that a DOR diagnosis does not mean that yous're infertile. If you are young (nether 35 years old) and regularly ovulating, your chance of getting pregnant is similar to someone with a "normal" egg reserve. If y'all are undergoing fertility treatments with DOR, you have options! Let's break information technology down below.

What exactly is ovarian reserve?

Your ovarian reserve refers to the number of eggs you lot have remaining in your ovaries.

Females are born with all the oocytes (aka eggs) that we will e'er have. When nosotros are in our mother's belly, our ain little infant ovaries take the maximum number of eggs. We are then built-in with about two 1000000 eggs, and by the time we become our starting time menstrual period, this number has dropped by virtually 75% to 500,000 eggs.

Throughout our reproductive years, we progressively lose eggs each month to the point where in that location are around ane,000 eggs left past the fourth dimension nosotros achieve menopause. How fast we lose eggs during our reproductive years can be unpredictable, but nosotros know for certain that progressive loss occurs.

"Diminished" ovarian reserve is when at that place are fewer eggs in your ovaries than the average for women your age, and in some cases, you may also lose oocytes at a faster charge per unit. Men have a very different circumstance . They have sperm stalk cells in their testes that continually produce sperm every iii months from puberty onwards. Unfortunately, women have no such equivalent stem cells, and so our egg reserve is finite.

How do we measure ovarian reserve?

Each month, your ovaries offer upward a new cohort of eggs for a shot at pregnancy, whether y'all are actively trying to conceive or not. Your encephalon secretes hormones which human activity like food for your eggs to grow and mature, but the brain just secretes enough of this hormone "food" for ane egg. The result is that one egg grows and ovulates, and that'south why we humans mostly have one baby at a time (every bit opposed to other species who have litters of babies).

As for the other eggs from the cohort that month? They essentially starve from lack of hormone "food" and and then disappear. So, there are actually a ton of wasted eggs each calendar month. I know, this sounds a scrap like the Hunger Games , simply your body is frugal, meaning if you lot take a depression egg reserve, your ovaries tin can sense that, and they will offer up fewer eggs per month in an endeavor to protect their reserve. This is actually ane of the means we mensurate ovarian reserve. We practise an ultrasound early in the menstrual cycle and run into how many eggs the ovaries are offering upwards. If they are offer upwardly a lot, they have a robust reserve. If they are only offer upward a few, they likely accept a low reserve. This is called your antral follicle count, more ordinarily abbreviated to AFC.

Another marking to measure out ovarian reserve is chosen Anti-Mullerian Hormone (aka AMH) , which is a blood test. All of the very minor eggs waiting to be offered upwardly in the ovary each secrete a small amount of AMH into your bloodstream. Your AMH stays steady throughout the menstrual bicycle, and then we can read AMH levels through a blood depict at any point in a month. However, information technology may be inaccurate if you are on oral birth control pills . If this is the instance, you may have a falsely decreased AMH which is completely reversible if you discontinue the pill.

The last indicator of egg reserve is chosen Follicle Stimulating Hormone (aka FSH) which is basically simply the hormone "food" that the brain sends down to the ovary to recruit one of the follicles that the ovaries have offered up that month. If the egg reserve is depression, and the ovaries are working hard to hold onto them, the brain has to send out more nutrient to entice the follicles out of the ovary. So, ultimately seeing a loftier FSH read early in the cycle means that the egg reserve is low.

How does ovarian reserve impact fertility?

So if yous only need one egg, why does it matter if you take 200 or twenty,000 eggs left? Skilful question! There is an of import departure between egg quantity and quality. Unfortunately, both decline with historic period, and they actually follow unlike patterns. Equally we discussed earlier, egg quantity falls in a progressive design during our reproductive years. But egg quality is different. Each egg is one cell that contains the genetic data you lot would laissez passer on to a potential child.

Egg quality is determined past the structural integrity of the egg and the proper balance of genetic material contained in that egg. We know that egg quality starts to drop in your mid-thirties and so once again more than sharply around historic period forty. The reason for this goes back to the fact that your eggs have been in your ovaries since you yourself were a fetus. So your eggs have been exposed to everything that you lot take—including toxins, radiations, you name information technology. Time, plus these other factors, accept a toll on the egg quality.

What exactly does this mean? For women under age 35, where the egg quality is adept , the chance that the one egg that gets selected is proficient quality and genetically normal is high. This is a very important fact to sympathize—low egg reserve below age 35 does not mean yous cannot get pregnant. Many women with depression egg reserve regularly ovulate expert quality eggs and successfully become pregnant.

However, if y'all are over age 35 with low egg reserve, things can get a fleck more than complicated. This is because egg quality starts to reject—so the chance that the 1 egg you ovulate will exist good quality goes down, and unfortunately, this is what makes it harder to get significant. In Vitro Fertilization (IVF) tin frequently exist a solution for women with DOR who are struggling to excogitate.

How does IVF work to treat DOR?

When we do IVF, we are not creating new eggs, we're simply capitalizing on the egg accomplice model that I described before—the Hunger Games thing. A fertility specialist will piece of work with you lot to determine the all-time handling protocol for your unique biology and will carefully dose you lot with enough of the egg growing hormone "food" (follicle stimulating hormone or FSH) for all the eggs your ovaries offered up that month to mature and survive. If your egg reserve is low and your ovaries are but presenting with a few eggs per calendar month, so we may get fewer eggs per IVF cycle than someone with a high ovarian reserve

For patients with low ovarian reserve, nosotros have many specialized protocols (read: tricks upwardly our sleeves) to maximize the number of eggs we get on each bicycle—no egg left behind! We can also do more than one IVF cycle to stack the numbers in your favor. Lastly, if yous know you have depression egg reserve and you also know that you will be delaying childbearing for a few years, egg or embryo freezing or banking might be a dandy option for you. Considering we know that both your egg quality and reserve will merely go down with fourth dimension, it makes sense to capitalize on that earlier and bank as many good quality eggs every bit you lot retrieve you will need for your family planning goals. To aid develop realistic expectations and to estimate the probability of your frozen eggs resulting in a baby, you can notice egg calculators online which are based on studies of frozen eggs that have been thawed and how many of those eggs turn into usable embryos or live births.

Are at that place other not-invasive treatments for DOR?

Unfortunately, we have not found any medications, herbs, or supplements that have been proven to aid egg reserve or prevent decline in ovarian reserve. I truly wish there was something we could recommend to our patients (trust me), merely zippo has been proven with medical research and information. Certainly, a prenatal vitamin which has all the practiced stuff including folic acrid (folate) is always recommended for whatsoever adult female of reproductive age, especially those trying to conceive. As it relates to egg quality, CoQ10 is a supplement that has some biologic plausibility. CoQ10 is a cofactor that the egg needs in order to metabolize energy, so it makes sense that it could potentially improve egg quality. There is a pocket-size randomized controlled trial from 2018 that demonstrated that supplementing with extra CoQ10 improved the quality of the embryos. The logic hither is that considering we have no test to determine oocyte/egg quality, nosotros use embryo quality equally a surrogate mark since the egg is the chief commuter of early embryo development.

What underlying factors touch on ovarian reserve?

By now you may be wondering what exactly causes diminished ovarian reserve? For the overwhelming bulk of patients who have low egg reserve, a specific crusade is non identifiable.

Nosotros think at that place may be some genetic or heritable component, as proven by similarities between the age at which a mother and a daughter go through menopause. Additionally, there are specific identified genetic mutations that tin make your egg reserve low, however, these are exceedingly rare.

Other environmental factors such as oxidative stress from the environment or smoking tobacco products may contribute to diminished ovarian reserve, as well as factors such as radiation exposure, which accumulates over time, and radiation therapy or chemotherapy to treat cancer and other diseases.

Decreased blood flow to the ovary during some types of surgery or removal of an ovary can crusade loss of eggs, and we at present also suspect that some environmental toxins as well as obesity may have some impact on egg reserve.

What are symptoms of DOR?

At that place are no overt symptoms of depression ovarian reserve; frequently women get normal monthly menstrual cycles and don't e'er know nigh it unless they see a fertility specialist as they are having trouble getting pregnant or desire to freeze their eggs. Then information technology is a fleck difficult to say exactly how many women accept diminished ovarian reserve because nosotros don't know nearly many of them. We exercise know that about 15% of the population has infertility , and of that specific subset, nearly 20-25% of infertility cases are due to macerated ovarian reserve.

What's next?

Ok, then now that y'all are armed with all this cognition, what should you do? The best place to beginning is really to recall about the large pic: what life or career goals practice you take and what is your timeline for that aspect of your life? What are your family planning goals and what is the timeline for that? It's benign to maintain regular intendance and contact with your gynecologist, who will probable address these topics with you each year at your annual visit besides as review your menstrual regularity, your family unit history in terms of menopause, and any risk factors for diminished ovarian reserve. A combination of these factors may prompt a consultation with a fertility specialist to make up one's mind your egg reserve. If yous accept been trying to conceive for half-dozen to 12 months and you are younger than 35, or 5 to six months after age 35, y'all should consult with a fertility specialist.

More than than annihilation, by arming yourself with information on your body and overall fertility, you're taking the first (and almost of import!) step in deciding what'southward best for you lot, based on your goals. Cognition is ability, and understanding what options are on the table is an empowering start footstep to meeting those goals.
