Over the next few weeks, the embryo keeps growing and — by week 6 of pregnancy, or about a month after ovulation and fertilization — it can be seen as a few-millimeter speck on an ultrasound. In some cases, however, something stops development during these first few weeks.
Either a fertilized egg never develops into an embryo but implants into the uterus anyway. Or something causes an embryo to stop growing in those first days after it implants in the uterus. In either case, doctors will diagnose a blighted ovum if they can only see an empty gestational sac and no embryo or no fetal pole — the first sign of an embryo on an ultrasound by around week 8 of pregnancy.
In other cases, genetic mutations, rather than whole chromosome duplications or deletions, are probably responsible for anembryonic pregnancies. A blighted ovum feels similar to a normal pregnancy, even after the fertilized egg has stopped growing.
That means many people who eventually find out they have an anembryonic pregnancy are still getting positive pregnancy tests and experiencing symptoms like morning sickness, sore breasts and bloating.
But a couple less normal signs can point toward a possible blighted ovum:. Because this condition occurs so early in the pregnancy, not all cases are diagnosed — which makes it difficult for experts to come up with an exact estimate of how often blighted ovum occurs.
But an estimated 10 to 20 percent of all pregnancies end in miscarriage, and 80 percent of those happen in the first 12 weeks.
Experts estimate that a third of even earlier miscarriages — those before 8 weeks gestation — are due to blighted ovum. In fact, there are likely undiagnosed cases of blighted ovum that women think are simply a period coming a few days late.

In a blighted ovum, a gestational embryo sac forms and grows; however, the embryo does not develop. A blighted ovum is also known as anembryonic pregnancy. Early pregnancy loss is the spontaneous loss of a pregnancy before 13 weeks of gestation. In the United Kingdom, miscarriage is the loss of an intrauterine pregnancy before 24 complete weeks of gestation. The World Health Organization WHO and the Centers for Disease Control and Prevention CDC define miscarriage as the loss of a pregnancy before 20 weeks of gestation or the ejection or removal of an embryo or fetus that weighs g or less.
This definition is used in the United States; however, it may vary based on State laws. Clinical miscarriage is when ultrasound examination or histologic evidence has confirmed the existence of an intrauterine pregnancy. In general, clinical miscarriage is classified as early before 12 weeks of pregnancy and late 12 weeks to 20 weeks. In Europe, the late loss is defined as one that occurs between 12 and 22 weeks.
Sporadic miscarriage is more common than recurrent. Sporadic miscarriage is when 2 or 3 consecutive pregnancy losses occur. The most common cause of blighted ovum is genetic.
This is often due to chromosomal defects from a poor quality sperm or egg too many or too few chromosomes in them.
However, in India, in addition to a genetic cause, causes include infections tuberculosis [TB] or structural defects of the uterus. Trisomies of all chromosomes have been found except for Chromosome 1 and Y. However, the frequency of these trisomies varies Chromosome 16 and to a lesser extent 2, 13, 15, 18, 21, 22, accounts for the majority of trisomic abnormalities.
According to a study by Edmonds in , trisomy 16 was found to give rise to the most rudimentary embryonic growth with an empty sac, while other trisomies often resulted in early embryonic demise. A study by Alberman implicated trisomies and monosomies for miscarriage at the modal peak of 9 weeks; whereas, triploidy pregnancy losses spanned 5 to 16 weeks of gestation. Recurrent miscarriage due to blighted ovum was significantly higher There is a link between DNA damage in sperm and miscarriage.
According to the research article by Larsen et al. According to the study done by Popovic et al. According to Larsen et al. In India, which includes 11 major states, the occurrence of induced abortion among women with RTIs is 2 times higher than those not affected by RTIs.
Congenital includes arcuate, didelphic, bicornuate, and septate uteri. Immunologic disorders in the mother such as NK Cell Dysfunction, autoantibodies, hereditary and acquired thrombophilia, among others can lead to the maternal immunological rejection of the implanting embryo in the uterus resulting in miscarriage.
Thyroid disorders thyroid autoimmunity and thyroid dysfunction and ovarian disorders e. Even modest amounts of alcohol increase miscarriage risk significantly. Moreover, study results suggested that the risk increased in a dose-related manner. A blighted ovum causes 1 out of 2 miscarriages in the first trimester of pregnancy. The prevalence of recurrent miscarriage is lower ranges from 0.
Clinical miscarriages only, prevalence is only 0. Signs and symptoms of a miscarriage are common and include vaginal bleeding and spotting. Menstrual periods may be heavier than normal. The patient may experience abdominal cramps. A pregnancy test can be done using urine or serum. There is an increase in serum and urine hCG. The indicator of the pregnancy test kit shows a weak positive usually a pink color instead of red. The criteria of the ultrasound for diagnosis is as follows:.
According to Campion et al. There are other diagnostic criteria for confirming with an ultrasound. In the United Kingdom, the Royal College of Obstetricians and Gynecologists recommends doctors to use the new guidelines to diagnose a blighted ovum, which is to monitor a growing gestational sac until it reaches at least 25 mm. A dangerous clinical situation could happen when the diagnosis is missed. The surgical procedure led to a massive intraoperative bleed. Although there is no prevention for blighted ovum cases most often it is a one-time occurrence , steps can be taken to increase the chance of successful pregnancy based on its multifactorial etiology.
Since blighted ovum has multifactorial etiology, the overall health, and well-being of the patient should be considered. To conceive one of the things emphasized by an obstetrician and gynecologist is having a well-balanced diet consume food for both mother and baby with all the necessary and recommended daily intake of nutrients and maintaining a healthy weight, is necessary.
Iron is found in meats, eggs, among other foods. Serbian or Hungarian goulash is a meat and vegetable soup or stew. Goulash is considered an aphrodisiac and a dish that might enhance fertility. In women with a low BMI, such diets rich in iron and other elements might increase the chance of conception. In the case study, the patient had a normal BMI, so food rich in iron is not needed. However, having a protein, iron, and trace elements rich diet such as this could enhance the immune system to fight or prevent infections UTI which she had.
A Himalayan drug company manufactures these. Speman enhances sperm motility and increases the chance of conception in women. However, there are no mandrake products for female infertility problems, only other plants as an aphrodisiac. As mentioned earlier in the Etiology section, recurrent miscarriage due to blighted ovum was significantly higher Therefore, couples need to be aware of this at the time of marriage and consult a genetic counselor when planning to start a family.
Some couples are hesitant to do a D and C as per the gynecologist or obstetrician's recommendation. There are several cases when the couple is told that they are going to miscarry. However, they wait it out through prayer and meditation, and when an ultrasound is done again after some time, they find the embryo in the sac. One such example was mentioned earlier in this presentation as examples of errors in diagnosis.
As per the Royal College of Obstetrics and Gynecologist new guidelines, monitor until gestation sac is at least 25 mm on ultrasound and wait 1 week more if no complications or symptoms of a miscarriage so that viable pregnancies are not misdiagnosed as miscarriages. Doctors and nurses should recommend couples wait for 1 to 3 regular menstrual cycles before trying to conceive again after any miscarriage americanpregnancy. According to Chauhan et al. In the United Kingdom, the Royal College of Obstetricians and Gynecologists RCOG as per the new guidelines, recommends that physicians monitor a growing gestational sac until it reaches at least 25 mm this would be about 9 weeks into pregnancy before diagnosing a blighted ovum.
One can be misdiagnosed as having a blighted ovum if diagnosed at 8 weeks or sooner. Many women who have a tilted uterus look 1 to 2 weeks behind and can be misdiagnosed as having a blighted ovum, so they should wait until at least 9 weeks if no complications when most women see the baby. The expertise of different ultrasound technicians positioning of the woman especially with a tilted uterus on the same day can affect the ultrasound measurements.
These measurements can be off 4 mm or 5 mm which can result in misdiagnosis. To access free multiple choice questions on this topic, click here. Blighted Ovum, ultrasound. Contributed by Tripthi M.
