Egg Count
Women are born with a finite number of eggs, typically ranging from 1 to 2 million, which gradually decreases over time. As women approach their late 30s and 40s, both the quality and quantity of eggs decline,
The best indicator to find track the quantity of your eggs is ovarian reserve testing – which tracks the Anti-Müllerian Hormone (AMH).
Egg Quality
The quality of a woman's eggs plays a crucial role in her fertility. Only a good quality egg can be fertilitised – leading to a healthy pregnancy. Understanding and addressing egg quality is essential when considering fertility treatments or family planning.
Egg quality declines as you age
No test can determine the quality of an egg.
Determining if an egg is chromosomally normal involves attempting fertilisation and then genetically testing the resulting embryo. As women age, DNA damage in eggs becomes more inevitable, making age a reliable indicator of the percentage of genetically normal eggs.
Egg quality primarily correlates with age, defining the expected proportion of normal eggs within a woman's total count. Unlike the varied range in egg count, age uniformly influences egg quality—women in their 20s tend to have mostly normal eggs with some abnormalities, while those in their 40s typically have predominantly abnormal eggs regardless of their lifestyle choices.
