Not Just Women: Men Also Face a Biological Clock
Rethinking the Biological Clock in Fertility For decades, public discourse on fertility has centered on women, often framing age as the sole determinant of reproductive success. The saying that a woman’s biological clock speeds up in her late 30s or 40s has shaped medical advice, personal decisions, and social expectations. But a growing body of…

Not Just Women: How Men Also Have a Biological Clock—and What It Means for Family Planning
Introduction: Rethinking the Biological Clock For decades, the phrase “biological clock” has often been used to describe women’s fertility aging. Popular narratives suggested that egg quantity and quality decline rapidly after the late 30s and early 40s, increasing miscarriage risk and raising concerns about conditions such as Down syndrome. A 2025 study challenges traditional beliefs,…

How Mitochondrial DNA Mutations Influence Cancer Growth
Understanding Mitochondrial DNA and Its Role in Cancer Mitochondria, often referred to as the powerhouses of the cell, are essential for energy production and various metabolic processes. Each mitochondrion contains its own DNA (mtDNA), separate from the DNA found in the nucleus. Recent studies have revealed that mutations in mitochondrial DNA can have significant implications…

Understanding the Impact of Mitochondrial DNA Mutations on Cancer Growth
Introduction to Mitochondrial DNA and Cancer Mitochondria are often referred to as the powerhouses of the cell, crucial for producing energy through the process of cellular respiration. Besides their role in energy production, mitochondria possess their own DNA, known as mitochondrial DNA (mtDNA). Recent studies have noted the presence of mutations in mtDNA in various…

Understanding Mitochondrial DNA Mutations and Cancer Growth
Introduction to Mitochondrial DNA Mitochondria are often referred to as the powerhouses of the cell. They play a crucial role in cellular energy production through the generation of adenosine triphosphate (ATP), which powers various cellular processes. Unique to mitochondria is their own DNA (mtDNA), which is separate from the nuclear DNA found in the cell’s…
