Can a 70 year old man be fertile? The reality of advanced paternal age

While it's a common misconception that male fertility lasts indefinitely, studies show a distinct decline with age. A 2020 study found that conception was 30% less likely for men over 40 compared to those under 30. This means that while a 70 year old man can be fertile, the process becomes significantly more challenging due to age-related changes in sperm quantity and quality.
