Scientists use fallopian tubes to estimate women's age in forensic cases

Researchers from Perm Polytechnic University and Perm State Medical University have created a computer program to estimate a woman’s age using her fallopian tubes. The tool aims to assist forensic medical examinations, particularly when traditional identification methods are unavailable. It could help address the over 12,000 unsolved cases of unidentified deceased individuals in Russia alone. The team studied fallopian tube tissue from 126 women aged 16 to 88, all of whom had given birth. Using microscopy and histological analysis, they confirmed two key patterns: the tubes gradually enlarge before menopause and then shrink with age. They also noted that the right fallopian tube is usually slightly larger than the left, a lifelong asymmetry.

The program works by measuring parameters like the diameter of tube sections and the thickness of mucosal and muscular layers. It then compares these with age-specific benchmarks to determine the most likely age range. This method was developed because existing approaches, such as genetic or dental records, often fail or produce errors of up to 15–20 years. The new tool offers a more reliable way to estimate age in forensic cases where other methods are ineffective. By focusing on predictable changes in the female reproductive system, it provides a concrete solution for identifying unidentified remains. The program’s accuracy could improve outcomes in investigations where age is a critical factor.
