What is a clear egg?
Diagnosed in early pregnancy, a clear egg means an "empty" egg. The egg and sperm meet, but cell divisions have not taken place and there is no embryo. Explanations:
For pregnancy to occur, the egg that travels through the tube is fertilized by a sperm. The egg is formed. Each time, it divides until an embryo is formed, which will then insert and implant in the uterus.
The clear egg or white egg is a well-formed egg after fertilization of the egg by a sperm, it implanted well in the uterus, but the cell divisions did not take place. There are no embryos.
What are the causes ?
Cell division got stuck at one stage. The growth and development of the embryo stopped, but the gestational sac continued to develop.
The causes of this development stop are still poorly understood. In two thirds of cases, a chromosomal abnormality is involved.
Today, scientists also point the finger at poisoning from heavy metals (lead, for example), responsible for the malformations of the spermatozoa that fertilize the egg. The egg produced by this fertilization is not viable.
At the origin of the clear egg, there are also hormonal and immune causes and abnormalities in the structure of the placenta.
How do you recognize a clear egg?
With clinical signs of pregnancy present, a clear egg usually goes unnoticed before the first ultrasound performed between the 9th and 11th week of pregnancy. This is the only way to detect it.
On ultrasound, a normal egg looks like a sac (called an ovular sac or gestational sac), it contains the embryo, which appears as a stain. The egg is alive and heart activity can be recorded.
A clear egg is an empty egg. The gestational sac measures about 2 cm, but there is nothing in it. There is also no heart activity.
Which exams?
Usually, a second ultrasound is done between the 5th and 10th day after the first to confirm the existence of a clear egg.
Why a second ultrasound? Because it is possible that the pregnancy age was miscalculated and the ultrasound performed too early. In this case, the egg is still too small and appears as a clear egg on ultrasound.
If the gynecologist still has doubts after this second check, he will prescribe tests for the beta hormone hCG. Normally, the level of this hormone rises very quickly in early pregnancy, then gradually throughout the course of the pregnancy. If her level does not change or has fallen on the second dose, the pregnancy has stopped. This dosage will only support the diagnosis of a clear egg, but results are often later.
Clear egg, what treatment?
If it is indeed a clear egg, it will expel spontaneously and naturally, leading to an early miscarriage.
A third ultrasound will confirm that the uterine cavity is empty and that the egg is gone. Otherwise, a surgical intervention (suction or curettage under general anesthesia) will allow it to be completely expelled (incomplete evacuation is the cause of profuse bleeding). It basically depends on the stage of pregnancy. It is sometimes indicated that contractions are started with medication when the egg is slow to expel on its own.
A clear egg, and after?
A clear egg is usually harmless, but of course, as with any miscarriage, the psychological side should not be underestimated, it is normal to experience an episode of blues or depression after having a clear egg. If necessary, you will be referred to a psychologist to help you overcome the psychological effects of the miscarriage and get over it.
Rest assured, the clear egg does not prevent normal subsequent pregnancies. It does not induce any gynecological or obstetrical sequelae on subsequent pregnancies and recurrences are rare. However, it is advisable to wait 2 to 3 cycles before planning a next pregnancy.
