Unless you actually have the tissue analysed from your blighted ovum, you will not know exactly what caused it. However, medical practitioners believe that the reason the embryo does not develop is because there are chromosomal abnormalities when the egg fertilises.
Although it is thought to be more common that the abnormalities lie with the egg, it is also possible that sperm that is not fully perfect can also cause a blighted ovum.
What you need to know is that there is nothing that you have done that could have cause the situation of a blighted ovum, so there is no point in blaming yourself. It is just natures way of stopping a pregnancy that would not form a functioning human, or one that would not go full term because of abnormalities.
The other thing that you should take note of is that the chances of having another blighted ovum once you have had one are very small and it is unlikely to happen again, albeit it is not impossible. The problem is that once you have had this type of loss, it is always in your mind when you next become pregnant.
There is some anecdotal evidence of supplements that you can take to improve the quality of your eggs but there is no guarantee that taking these will mean that you will not suffer from a blighted ovum.
It is reported that introducing DHEA to women going through IVF in particular gave better results in terms of embryo quality and a lower miscarriage level. You can buy DHEA over the counter and on Amazon.
There has also been a limited amount of reserach carried out into the benefits of taking Coenzyme Q10 (CoQ10) in older women. One study found the following:
“We pretreated 52-week-old ICR mice with the mitochondrial nutrients coenzyme Q10 (CoQ10), r-alpha lipoic acid, and resveratrol before ovarian stimulation and ﬂushing of oocytes from the fallopian tubes. Our preliminary data demonstrated that CoQ10 treatment, but not the other two nutrients, was associated with increased oocyte numbers and oocyte mitochondrial activity parameters, similar to oocytes from young ICR controls.”
Many people therefore advocate taking CoQ10 for 3 months prior to conception to enable an increase in egg quality. Once again there is no guarantee that this will not lead to a blighted ovum or any other type of miscarriage. CoQ10 is also available at Amazon.
