Women above the age of 35, slowly their reservoir of eggs is going down and also because we are born with the eggs we have, our eggs age with us and therefore a 35 year old egg will be poorer quality than an egg of a 20 year old in general. From the age of 35 the chromosome abnormality can slightly increase and this increases significantly in eggs after the age of 40. Not only we lose the quantity of the eggs, we have in our ovaries the eggs that are remaining at the after the age of 40 also become more chromosomally imbalanced and as a result of this, this is why we see women over the age of 40 may have do have less success with IVF so their chances of pregnancy naturally or with IVF reduces they can produce more chromosomally abnormal embryos which if whether through IVF or natural process of getting pregnant can increase the miscarriage rate and this all goes back to the quality of the eggs and the eggs being chromosomally more imbalanced and not producing good quality embryos. If we have chromosome abnormality or imbalance in the egg, it can lead to producing embryos that are also chromosomally abnormal

Can be genetic factors, can be diet and lifestyle but usually to do with age. It’s usually age related. As we get older, there are certain factors within the egg that maintain the resilience of that egg and we have fewer of those and they function less well as we get older. Mostly age, also genetic factors and diet and lifestyle.

Eggs can look a bit dodgy when we pull them out maybe. They might have a bumpy cytoplasm or look a bit not quite right when we get them out. Maybe they don’t fertilize, maybe they don’t develop into nice cleavage stage embryos so they’re not dividing into two and three and four cells or maybe they do all of that and they just don’t make it to blastocyst. All of these things can be indicative of an egg quality issue.

How do you know if you have poor egg quality?

Inability to get pregnant in women over 35 years old frequently is blamed on poor quality of eggs. Even though nowadays, we know that the factor of infertility can be as often male or a combination of both, this tendency is present. How can we be certain that the eggs are the cause of not achieving pregnancy? What symptoms or tests can be expected to confirm that?
