In case of fertilization and segmentation of one ovum monozygotic twins are produced, while in case of fertilization of two ova, which can originate from one or two Graff follicles, dizygotic twins are developed. The ratio of twin and single pregnancies is according to Hellin's law 1. The incidence of twin and other multiple pregnancies is influenced by: race of parents, age and parity of mother, use of clomid and gonadotrophin to stimulate ovulation, discontinued use of contraceptive pills and certain seasons exposure to sunlight 1. Due to occurrence of numerous complications twin pregnancy and parturition are considered to be highly risky.
This fact again emphasizes the importance of correlating hCG levels with sac size, rather than treating all empty sacs equally.

It is an unfortunate fact that spontaneous pregnancy loss SPL is a common condition among humans 1. Approximately half of all embryos are lost before a pregnancy is known to be present by the mother or clinician 2. The risk of pregnancy loss is well known to be even higher among women with symptoms of vaginal bleeding, and among older women 3.
Sonographers have long recognized their potential contribution to the evaluation of early pregnancy and embryonic viability. Another pioneer, Dr Hugh Robinson, produced much of the original work on early normal and abnormal pregnancies 5 - 7. He not only set the stage for future studies, he defined the goals.
Before making reliable diagnoses of SPL we must first accurately characterize normal pregnancies. In doing so, the current authors distinguish between threshold levels and discriminatory levels of any measurement of normal development.
A threshold level tells us the earliest we can expect the pregnancy to reach a certain landmark, while the discriminatory level tells us when we should also expect this landmark. For example, a living embryo may be detected by 5. Conversely, diagnosis of a failed pregnancy should only be suggested when there is failure to detect a living embryo after a certain discriminatory level.
While the threshold value may vary with ultrasound frequency and resolution, the discriminatory value is more dependent on biological variation. It is clear then that in making reliable diagnoses of SPL using a single criterion, we should always consider the discriminatory values.
While Dr Robinson's goal of complete reliability is usually straightforward when a discrete embryo is identified 12 , 13 , in many doomed pregnancies the embryo either fails to develop or does not develop beyond a rudimentary stage. In these patients, trophoblastic activity may continue despite the absence of a developing embryo Because early normal pregnancies also show a gestational sac but no detectable embryo during a brief but finite stage of early development approximately 4.
Although all diagnosticians recognize the value of adding the dimension of time and serial observation to particularly difficult cases, this philosophy should not become so pervasive that one virtually abdicates diagnostic responsibility.
Once a failed pregnancy has been reliably diagnosed, nothing is gained by additional assessment. Among the hormonal studies, progesterone and hCG levels are more accurate than the others. Falling hCG levels predict pregnancy failure quite accurately.
Unfortunately, serial hCG determinations are not uncommonly equivocal. There are a number of sonographic criteria for diagnosing SPL 20 , 21 and these have been analyzed in detail Among the most predictive criteria for diagnosing a failed pregnancy is a large gestational sac without a living embryo Gestational sac size is normally a good predictor of gestational age: the sac is first visible by 4.
For this reason, there is an excellent correlation between sac size, gestational age, and hCG levels As the pregnancy progresses, normal development of the embryo and embryonic structures also occur in a very predictable fashion until a living embryo is visible.
A living embryo may be seen in normal pregnancies when the sac is as small as 10 mm threshold level and should always be seen above a critical discriminatory sac size. This discriminatory sac size has been proposed to be in the range 20—30 mm using transabdominal ultrasound, and in the range 16—20 mm with transvaginal scans 22 , 26 - Another common and useful sonographic feature for predicting SPL is a disproportionately enlarged amnion compared to embryonic development During very early pregnancy, the crown—rump length is approximately equal to amnion sac diameter, again illustrating that normal embryological development is predictable and highly consistent.
Such enlarged amniotic cavities may be confused for an enlarged yolk sac. Larger amnion cavities tend to be found in larger gestational sacs but this sign is also valid when the amnion is small. Empty amnion.
Transvaginal scan shows a gestational sac measuring 16 mm in mean diameter, without a living embryo. The yolk sac YS is smaller than seen with most normal pregnancies, but is normally pushed to the periphery by the expanding amnion arrows. An embryo of approximately equal size to the amnion is expected within it at this time.
The findings are diagnostic of a failed pregnancy. In most cases we have more than one sonographic criterion in addition to clinical data to indicate that a pregnancy has failed. Also consistent with previous studies, both groups found that clinical factors associated with an increased risk of a pregnancy failure included: increased maternal age, increased menstrual age, lower hCG levels, lower progesterone levels, and vaginal bleeding. Unlike the existing literature, neither study found that an absolute sac size reliably distinguished normal from failed pregnancies.
However, this is not unexpected since Falco et al. Both studies suggest a higher accuracy of interpretation when clinical and laboratory data are correlated with ultrasound findings for diagnosing failed gestations. Falco et al. This fact again emphasizes the importance of correlating hCG levels with sac size, rather than treating all empty sacs equally. One also wonders about the necessity of hCG levels, if the menstrual dates are certain, since lack of a living embryo by 7 menstrual weeks would be considered diagnostic of a failed gestation without the need for other criteria.
Conversely, if the menstrual dates are uncertain, correlation with ultrasound and the menstrual dates again proves to be very helpful. Conversely, if the menstrual dates are unreliable or potentially in error and the gestational sac appears normal, then we must disregard the dates and assume the pregnancy is viable until proven otherwise. Progesterone levels may be more helpful than hCG levels for evaluation of early viability.
Low progesterone levels are known to be associated with a poor prognosis 38 , and this observation is confirmed by Elson et al. However, because low progesterone levels may occasionally be seen in normal pregnancies, progesterone levels alone may not be diagnostic.
A unique observation by Elson et al. Given the extensive literature comparing sonographic findings with hCG levels, it is perhaps surprising that there are not more studies correlating ultrasound findings with progesterone levels. Incorporation of gestational sac size with maternal age is a logical improvement on the use of progesterone for diagnosing failed pregnancies.
As the model of Elson and colleagues predicts, low progesterone levels may be seen with normal pregnancies, but only when the pregnancy is very early. The two papers presented here illustrate that experienced clinicians rarely work with a single piece of information and must consider a number of variables simultaneously. No formula is a substitute for clinical skill and experience in considering all of the information to obtain a diagnostic impression.
The range of examination and interpretive skills in sonography is simply too broad for that. The vast majority of failed pregnancies will have more than one sonographic and clinical criterion to add credibility to the impression of a failed pregnancy, and as clinicians we use all of this information to arrive at a final diagnosis.
In the final analysis, when considering criteria useful for diagnosing SPL, we once again return to Hugh Robinson's objective by aiming for a certain diagnosis before actively managing such pregnancies. This goal is just as valid today as it ever was. Future studies can be anticipated that also attempt to simulate clinical experience with objective parameters on a single examination. As the current papers illustrate, the most useful methods will undoubtedly correlate a variety of sonographic, clinical, and laboratory results in predicting pregnancy outcome.

Health Disclaimer This page was last updated on Oct 27, And as newlyweds, we were still really getting to know one another in this new framework of husband and wife. To add to things, we came with about a thousand dollars total in our savings, with no jobs or real idea as to how we were going to survive.
We knew that we wanted my husband to be able to spend the first year learning in kollel , in yeshiva , since after that, he would not be able to dedicate all of his time to learning. I, therefore, was going to work and support us. However, we never factored into the equation that we arrived weeks before the month of Tishrei , filled with Jewish holidays, and the worst possible month to seek employment.
Our apartment was barely bigger than a shoebox, and with no air-conditioning, it was unbearable in the heat of the Israeli summer. It had been a few weeks with no work, no prospects, and no break in the heat wave, when suddenly I began feeling terribly nauseous. It took me another week or so to decide to take a pregnancy test, and to my surprise and shock, I found myself staring at two small lines in the window. I was nervous, scared and overwhelmed.
We also knew that in our situation, we would have few people supportive of our decision to have a baby right away. To them it seemed irresponsible, premature and entirely inappropriate. Needless to say, my job hunting now became nearly impossible. Just getting out of bed in the morning was extremely difficult, only to board a crowded bus, feel sick, and find myself jumping off in the middle of nowhere desperately seeking a garbage can.
I was used to being in control of my life. I was organized, kept track of things, and made sure to do what needed to be done. Suddenly, I was a mess. I would sleep endlessly, accomplish what seemed to be nothing, and still be tired at the end of the day.
Then one day I noticed the slightest trace of spotting. At this point I decided to call a doctor and ask if I should be concerned. When I was told to immediately get to the office for an ultrasound, I froze. Until this point, my pregnancy had been a given. After all, I hadn't been doing anything to prevent it, so of course I was pregnant.
And so I thought that of course I would have an easy pregnancy, of course there would be no complications, of course I would have a smooth delivery, of course I would have a beautiful baby. It never occurred to be that there could be a problem. If anything, this pregnancy had been interrupting my normal life, and I was a bit annoyed, though generously putting up with it. I was excited about the baby, just had no patience for the process of getting there.
My husband went with me to the doctor. It was Succot and it was my birthday. I remembered how in high school my best friend and I had decided the perfect age to get married, and the perfect age to have a baby. Immediately, they wanted to do an ultrasound. I had not yet had one and, not realizing how serious my situation was, felt quite excited to see my baby.
The doctor jelled my stomach, and I watched the screen as he moved the instrument around. He continued to search, yet had a blank expression on his face. How do you respond to that? What does that mean? I am not one to cry around others, but the tears just started to stream down my face.
The doctor tried to calmly explain that I had a blighted ovum. That the pregnancy never actually happened, and that I basically had a group of cells inside a pregnancy sac, but no fetus. But suddenly I was left with nothing to do. It was as if nothing had ever happened. It was as if I had fallen for some false reality that never took place. For three months, I thought I was carrying around a baby. I spoke to this baby, I connected with this baby. I loved this baby.
In truth, at least medically speaking, I was never really pregnant. I had pregnancy cells, but no pregnancy. So while my belly swelled and body went through the typical symptoms, the problems was that the fetus itself was missing. I felt like a fool. I thought that I should have known better. The rest of my experience was only more horrible. As I sat and cried, they cuddled their babies. There were the nurses, who though they were trying to be kind, told me not to worry, that I was young, that I would get pregnant again.
The truth is that I was in too much of a daze to have even cared. Physically I knew I would be fine. The thing I remember most is that I felt so alone. I felt like there was no one who could understand me, and no one who had gone through this before.
Or so I thought. I felt like a failure as a woman. What if I never could? The thoughts were overwhelming. I was terrified that maybe I would never have a child. And then I thought about all the times that I was annoyed with my pregnancy. All the times I had wished that it had happened at another time.
And no, by no means did I think that I had caused this loss. By no means did I think that this was some form of punishment. But rather, I so badly wished that I could have used the time to have recognized what a miracle pregnancy is.
Until I had miscarried, I knew nothing about miscarriage and thought that it was a very rare occurrence. I had no clue how common it was or how many women had suffered. Suddenly, as those who were close to me found out about my situation, the phone calls starting pouring in.
Women who had numerous kids, who always seemed to be pregnant, told me of their stories and losses. One woman who had just had her seventh child, said that for each baby she birthed, she had lost one.
I was amazed. These women were supportive, helpful and encouraging. But most importantly, they drove home the message that nothing, absolutely nothing, can be taken for granted.
I did not get pregnant immediately after as some had told me I would. I did not feel better a few weeks later either. To be honest, I was traumatized for some time, and in a certain sense, forever. I had lost a part of me with that pregnancy. There was a baby that would never come into this world, and there was an innocence and arrogance that protected me that was shed for good.
Unfortunately, this was not my only miscarriage. I suffered another one a few years later. But this time, the knowledge that I was not alone and that there was nothing wrong with me made it that much more bearable. Yet it was still horrible and scary. This was my third pregnancy, and two had been miscarriages. Not a good ratio. Even though, unfortunately, the statistic is that one in three pregnancies end in miscarriage. Through my losses, however, I was also able to gain tremendously.
I had a level of gratefulness with my pregnancies that I carried from the moment I found out until the birth. When I was tired, irritable or not feeling well, I reminded myself of the blessing and miracle, and how happy I was that my baby was healthy. And I learned that you can never know what someone else is going through.
Everyone has a story. Everyone has a difficulty. No one can be judged. Though I lost two pregnancies, both in the 14th week, I have been blessed with four children, fairly close in age. With the oldest 6 and the youngest 1, often I am asked how many more I plan on having.
No doubt I have been blessed. Rabbi Ginsburgh, my rabbi, taught me the most beautiful lesson after one of my losses. He explained that every soul that is brought into this world comes for a very specific reason and serves a very special purpose.
We live our lives to fulfill this mission and it takes each individual a different amount of time, along a unique and specific journey. Sometimes these souls need to live a full lifetime, others for just a few years, others for only a few months, even at times just a few days. Then there are the souls that need so little to complete their mission, that their soul only needs to come into a body long enough to beat its heart or simply create a pregnancy.
These are the highest of all the souls—the souls of the truly righteous and pure tzaddikim whose mission took so little to complete.
However, for the woman who had lost her pregnancy, this does not take away the pain. This does not take away the suffering.
But it does give it meaning and it does make it easier. While I pray for myself and for others to only have pregnancies, births, babies, and children that have much to complete and much to accomplish so that they live long and full lives, I feel fortunate to know that my loss was not for nothing.
Unlike what the doctor had said, that sac was not empty. And all the morning sickness and emotional trauma did serve a purpose.
A very important purpose. For I was chosen, for one reason or another, as the conduit to aid a very holy soul in its vital and final mission. And that means the world to me. The information provided is for informative purposes only and in no way is intended to give either medical or halachic guidance.
Please consult your doctor or rabbi for any questions in these sensitive areas. God I thank you so much for this. Currently going through the same thing, and every emotion and thought you have expressed has mirrored my exact experience, although I already do have a healthy beautiful boy.
Just thank you. Thank you for helping me feel less alone. I somehow have not seen them until now, but Ivana, when I read of your loss, I saw all the comments from all of you strong women who took the time to comment. Please know that sharing your story undoubtedly brought strength and comfort to others in knowing they were not alone. I only hope and pray that now, from the time you commented, that you find yourself in a different situation and that you have been blessed to have a healthy pregnancy and baby.
For those who have not, please do not lose faith and know that it can happen and that while you are waiting, you have so many gifts within that you can and must share with the world. Ivana, as you posted most recently, please know that time does help heal the pain and you will move forward even though right now that feels so impossible.
I pray you soon experience a healthy pregnancy and birth! Thinking of all you women! Hello Sara, Going through the same thing, an empty sac. I hope I have the same blessing as you with 4 kids. Hi Sara, I am so happy to have come across this, i am currently passing "an empty sac.
Your words and story has helped me somewhat come to terms with what is happeneing. I am so sorry ro read of your losses, but very happy you were able to bring 4 lives into this world. Hi Sara, Thank you for the writing.. Undergoing something similar.. Unsure if my pregnancy is going to make it..
I have been asked to wait for a week more to check and decide further on the progress. I have been in a mess the whole week. Crying and depressed as I got finally pregnant after struggle via IVF.. Wow thank u for writing this article. You helped me put into words what I have been feeling for the last couple of weeks. My first two pregnancies were empty sacs as well. It was so devasting. I thought for sure I wouldn't be able to have children. Than a miracle my first son. After him we were blessed with twin boys.
Recently I lost another baby. I am once again feeling the pain of a loss. So confused. Why did this happen again?
The Empty Sac - Personal Stories: Loss
After a home pregnancy test has turned positive and a blood test measuring levels of human chorionic gonadotropin HCG have confirmed pregnancy, the next proof of pregnancy is an ultrasound. When you have your first ultrasound your doctor may talk about the presence or absence of the gestational sac. What exactly is the gestational sac , when can it first be detected on ultrasound, and what does it mean if it is or isn't there?
What does it mean if a gestational sac is seen, but appears to be empty? The gestational sac is found in the uterus and on an ultrasound, it appears as a white rim around a clear center. The gestational sac is usually seen when your hCG levels are between and If a gestational sac is seen on your ultrasound, is this a guarantee of a normal pregnancy? Visualizing a gestational sac is certainly a positive sign of pregnancy, but it is not a guarantee that your pregnancy is healthy and will proceed normally.
For example, after the sac becomes visible, the next positive sign of pregnancy is a yolk sac that develops within it. The yolk sac provides nutrition to the developing embryo until the placenta takes over, and is thus an important indicator of pregnancy health.
In some cases, a gestational sac will be detected on ultrasound, but a yolk sac is subsequently not found. If a gestational sac is not seen on your ultrasound, what does that mean? There are several possible reasons for a lack of a gestational sac. It could be that:. An ectopic pregnancy can be a medical emergency, and if this is a possibility your doctor will want to do further testing and talk about treatment options.
An embryo is usually seen within the gestational sac by 6 weeks gestation. One of the more common types of miscarriages, known as an anembryonic pregnancy, empty sac, or blighted ovum, happens when a gestational sac does not contain an embryo.
In other words, an embryo failed to develop. This type of pregnancy loss occurs early in the first trimester, and often before a woman even realizes she was pregnant. In most cases, chromosomal abnormalities will cause the woman's body to miscarry naturally and without intervention.
This procedure may be desirable for women who want a pathologist to try to find a cause for the miscarriage, for those who feel it will help them cope better with the loss, or for physical or medical concerns raised by her physician. If your doctor discovers an empty gestational sac on an ultrasound, he may confirm that your pregnancy is nonviable—in other words, that the pregnancy will not result in the birth of a baby as it is not progressing normally.
But sometimes depending on the size of the gestational sac , it may be a bit too early to determine that the sac is truly "empty. Early transvaginal ultrasounds are a relatively easy way to follow a pregnancy early on, and along with hCG levels can give you and your doctor an idea about how your pregnancy is progressing.
The gestational sac is the first structure physicians look for with early ultrasound. When it is present between 3 and 5 weeks gestation , it can be a positive sign.
That said, sometimes a gestational sac is seen but is found to be empty, without evidence of an embryo by 6 weeks gestation. On the other hand, sometimes a gestational sac is not seen. The most common reason for this is inaccurate dates and it is simply too soon. But if a gestational sac is not seen on follow-up, or if your hCG levels indicate one should be seen, you could potentially be having a miscarriage or ectopic pregnancy. Pregnancy can be a joyful time, but one ridden with anxiety as well when things don't go as you'd like.
Lean on your friends and family members. If it's thought that you are having a miscarriage, have a blighted ovum, or an ectopic pregnancy, it can be a huge emotional blow. This is especially true as many couples haven't yet shared their pregnancy with family and friends, so you may feel very alone.
There are stages of grief associated with miscarriage , even when it occurs early. Added to that are the often well-meant but hurtful comments such as "you can always have another. Get diet and wellness tips to help your kids stay healthy and happy. Cunningham, F. Gary, and John Whitridge Williams. Williams Obstetrics.
Your dates are off. This is a common reason and may simply mean that you need a repeat ultrasound later on. It can be helpful to compare this finding with your hCG levels, which would likely be lower than if you are not as far along as you thought in your pregnancy. You have miscarried. It could be that you had a very early miscarriage chemical pregnancy or that you will be miscarrying. Falling hCG levels are also a sign of miscarriage.
You have an ectopic pregnancy. If your hCG levels are between and but a gestational sac is not seen, it could mean that you have an ectopic pregnancy.
