What is it and why does it happen?

A pregnancy where the fetus does not develop is called an anembryonic pregnancy, also called anembryonic or more popularly known as "blind egg".

Everything happens at the moment when pregnancy begins, when for some reason cell multiplication does not occur in the proper way, the process occurs naturally as in any pregnancy, the sperm fertilizes the egg, forms the zygote and begins to carry out cell division, a part of this cell division will form the gestational sac, the placenta and the amniotic fluid and the other part that would form the fetus does not develop.

I had an anembryonic pregnancy can I have another?

It is common for both men but especially women to think that there may be something wrong with their body, but anembryonic pregnancy is considered an "accident of nature" and not even experts know for sure its cause, it is something that can happen to anyone. , but that doesn't mean that a woman can't get pregnant again, and if she gets pregnant, it doesn't mean that the same problem can happen either.

How many weeks does anembryonic pregnancy last?


Usually when the blind egg happens, the woman's body recognizes that there is something wrong with the pregnancy around 6 weeks, at this stage the pregnancy hormones are reduced and the body eliminates it through miscarriage.

But there are cases where miscarriage does not happen and in these cases it is necessary to perform a procedure known as curettage.


Around the 6th or 7th week of pregnancy the obstetrician will perform the first ultrasound, if the doctor suspects that the pregnancy is anembryonic he will recommend waiting until the 8th week to be able to confirm that it is really a pregnancy without a fetus through another ultrasound .

The diagnosis is considered positive when the gestational sac is 25 mm in size but without embryo, if the gestational sac is smaller, it will be necessary to schedule another ultrasound, as the pregnancy may be at a less advanced stage.


Anembryonic pregnancy occurs in the same way as a healthy pregnancy, and the symptoms presented are the same, so simply through the symptoms it is not possible to make a diagnosis.

If there is no miscarriage, only at the end of the 6th week will it be possible to identify it through ultrasound.

Are there treatments?

There is no treatment for the blind egg, this is because it is a fatality of nature, something that can happen to any woman but is not common.

What is not common is if there is more than 1 consecutive miscarriage, in these cases it is necessary to inform your doctor so that he can carry out more detailed exams to check for any other problems.

How soon can I get pregnant again?

Before starting to think about a new pregnancy, it is ideal to give yourself time to recover from the sadness that occurs when you know that there was no healthy fetus, it is important to reiterate that after an anembryonic pregnancy does not mean that it can happen a second time.

The ideal is to consult your obstetrician to find out more and to know more precisely how long you should wait, on average the body takes 3 to 6 months to fully recover.

Is curettage necessary?

Curettage is an invasive procedure that aims to remove any remnants of anembryonic pregnancy from the woman's body.

Usually after 8 weeks the body naturally eliminates that pregnancy through miscarriage, if it doesn't happen through miscarriage, the doctor can prescribe medication that will induce abortion.
