Summary:
- Polycystic ovary syndrome (PCOS) is a common hormonal disorder that can cause infertility, irregular periods, and other health problems.
- Research suggests that PCOS may be passed down through families, and this could be due to "epigenetic memory" - changes in gene expression that are inherited but don't involve changes to the DNA sequence.
- The study found that certain epigenetic markers associated with PCOS were passed down from mothers to daughters, even in daughters who did not develop PCOS themselves. This helps explain why the condition tends to run in families.
