Kira Jones was 19 when a blood test changed her life forever.
She worked at a fertility clinic in Hertfordshire, England, and decided to take an anti-Müllerian hormone test simply because it was available there. The result was 5,8 pmol/l, far below the normal range for her age, which is 8,7 to 83,6. The doctors were direct: her ovarian reserve was comparable to that of a woman nearly 45 years old. She was in perimenopause without ever suspecting it, with just a few irregular periods that she attributed to something unimportant.

She was told that if she wanted to preserve her eggs, she had to act immediately, with no time to think it over calmly. She borrowed money from her family and underwent two rounds of egg retrieval: of the 26 eggs collected, 17 were frozen. Today, at 25, she lives with osteopenia in her hips, has regular bone scans, and describes a brain fog that makes her feel, in her own words, like a child again.
