According to Professor Thierry Harvey, gynecologist and obstetrician, the is the action for a woman of ovulate twice with an unconformity. For example, two ovulations several days apart. " a first fertilization takes place and eight days later the pregnant woman fertile a second time. It can also be the appearance of a delayed heart activity says the professor. In in vitro fertilization, for example, it is two eggs with very early egg separation. “both are going to have different sizes and weight and at this time, as an obstetrician we ask ourselves whether the small or low weight doesn’t have a health problem” he continues .
Myth or reality?
" there have been a dozen cases in the world but nothing has been proven and I have not known in my professional life similar fact. I’m not sure it’s possible says gynecologist Diane Nenarokov.
Philippe Deruelle, Gynecologist-Obstetrician and Secretary-General of the national college of gynaecologists and obstetrician talks about the implementation of a pregnancy while a pregnancy is already present. " the is when 2 pregnancy is present in the same womb, which is a relatively rare phenomenon he explains. But very common in our friends for example. As soon as a second pregnancy is found, we will first look at the ultrasound if there is not a defects in the cells. If this is not the case, it is that two fertilization took place a few days apart.
This phenomenon involves the combination of several factors. It takes two oocyte reports and an oocyte that lasts, because the life of an oocyte is 3 TO 5 days!
The lag between the two fertilization must be important, that is, at least more than 5 days. But beyond, a second pregnancy would not be possible because the first, already at an advanced stage, would not allow the implementation of a new egg. But as the obstetrician reminds us, “you know, the mysteries of the human body”.
So there are 2 Hypotheses. Either, the 2 ovulations are delayed in time, which is complicated, or the 2 reports have generated 2 fertilization.
Philippe Deruelle explains that this phenomenon has no impact on the health of the 2 foetus and that both pregnancy will have normal monitoring, as for twins.
The birth of the first baby will give birth to the second, as in the case of the twins.
We found a few cases
2009 a Arkansas
2015 in Australia
2016 California
