Fertility After 35
Fertility After 35: What You Need to Know
How age affects egg quality and quantity, and what options are available to you today.
Age is one of the most significant factors in fertility, but 'declining fertility after 35' is a broad statement that deserves more nuance than it usually gets. Here's what's actually happening, and what your options look like.
What we help you with:
- What actually changes with age: both the number of remaining eggs and the proportion that are chromosomally normal decline over time — this trend accelerates somewhat after 35 and more noticeably after 40, though the exact pace varies significantly between individuals.
- Why testing matters more than a birthday: AMH levels and antral follicle count give a much more specific picture of your own ovarian reserve than age alone — two 38-year-olds can have meaningfully different fertility profiles.
- Options worth knowing about: egg freezing preserves eggs at their current quality for future use; PGT-A testing can help identify chromosomally normal embryos during IVF, which becomes more relevant as age-related chromosomal abnormality rates rise.
- What age doesn't determine on its own: many patients over 35 conceive successfully, with or without treatment — age changes probabilities, not certainties, and a personalised work-up tells you far more than a general statistic does.
If you're over 35 and thinking about starting a family now or in the future, the most useful next step is a fertility assessment specific to you — not a general age-based assumption either way.
