The menopause marks the end of the fertile period in women. This affects the hormone balance and can present risks such as heart problems and osteoporosis. Yet the phenomenon of the menopause is unique; almost no other animal experiences such a halt in fertility. Researchers therefore want to understand why only humans and a few whale species experience this.
Scientist Deena Emera is researching how different animal species maintain their fertility and what happens within their genes. Her goal is to discover how some animals stay fertile for longer and whether these insights can be used for humans. For example, she is studying genes involved in the maintenance of egg cells and DNA repair.
This research could help in the future to find better treatments than current hormone therapy. Hormone therapy does not help everyone and can have side effects, such as an increased risk of strokes. By learning from animal strategies, the health and quality of life of women at a later age may possibly be improved.
The study contributes to increasing women's freedom of choice regarding fertility and the timing of the menopause. Insight into natural mechanisms can lead to new possibilities for remaining healthy and vital for longer.
