Why does fertility drop so sharply with age? 🤔
Not all embryos are chromosomally normal (euploid). At ≤35 years, nearly 60% of embryos are normal — but by 44, only about 12%. This decline explains why fertility treatments rely so much on embryo genetics. Age affects not just egg count, but also the blueprint within each cell.
Understanding this can help in making informed decisions about family planning and fertility options. 🧬✨
