How Photobiomodulation Improves Ovarian Granulosa Cells
Improve Granulosa Cells and Oocyte Metabolism with Red Light Therapy (Laser).
When it comes to fertility, a lot happens behind the scenes inside your ovaries, think of it as a a symphony of cells and hormones collaborating to produce the ideal environment for the egg to mature optimally. Granulosa cells play an important role in this symphony. These specialist cells function similarly to the pit crew in a Formula One race, working nonstop to ensure the egg is adequately nourished, supported, and ready to race (ovulation).
PBM acts as a performance-enhancing tune-up for these cells. Let's look at why granulosa cells are so important in fertility and how oxidative stress affects their performance.
What Are Granulosa Cells?
Granulosa cells are specialized ‘caretaker’ cells that surround and nourish the developing egg (oocyte) within your ovaries. Consider the egg to be a little seed, with the granulosa cells acting as gardeners, providing water, nutrients, and optimal soil conditions for growth. These cells control hormonal signals, produce a protective habitat, and even maintain the precise balance of oxidative stress surrounding the egg. Without healthy granulosa cells, the egg cannot realize its full potential.
The Hidden Threat: Oxidative Stress and ROS.
Granulosa cells are particularly vulnerable to reactive oxygen species (ROS), which are unstable chemicals created spontaneously during cellular metabolism. At low levels, these chemicals are beneficial, assisting in cell communication and ovulation-related activities. However, when ROS levels become too high, oxidative stress ensues, causing cellular damage.
For granulosa cells, oxidative stress can:
Disrupt their hormone regulation.
Damage the cell's energy centers, known as mitochondria.
Impair follicular development, making the egg susceptible to chromosomal defects and poor maturation.
Consider oxidative stress to be a corrosive force that wears down the gardeners' (granulosa cells) instruments for nurturing the seed (the egg). Over time, this reduces their ability to produce a thriving habitat.
How Does PBM Reduce Oxidative Stress and ROS?
Photobiomodulation (PBM) protects and rejuvenates granulosa cells by addressing oxidative stress and supporting their critical role. PBM works by energizing the mitochondria, the cell's powerhouse, while also enhancing the cell's natural defense systems.
Also:
Reduces ROS Levels: By optimizing mitochondrial energy production, PBM reduces the creation of excess ROS, similar to tuning a car engine to reduce emissions.
PBM boosts antioxidant defenses by stimulating the production of antioxidants like superoxide dismutase (SOD) and glutathione, which neutralize damaging ROS and protect cells.
Repairs Damage: PBM activates the cell's inherent repair mechanisms, allowing granulosa cells to recover from oxidative stress and regain function.
Improves Energy Availability: Increased mitochondrial function ensures that granulosa cells have the energy they need to do their work.
Research on Granulosa Cells
Human and animal studies have demonstrated that PBM can regulate granulosa cell activity and improve oocyte metabolism. The researchers have observed:
Granulosa cells have increased mitochondrial activity, resulting in improved energy production and healthier oocytes.
Improved oocyte quality, as PBM promotes egg metabolism and decreases oxidative stress.
Boosts VEGF Production - vascular endothelial growth factor (VEGF), which helps grow new blood vessels to deliver oxygen and nutrients to the follicle (the egg’s protective home).
Enhanced follicle growth creates a more favorable environment for egg maturation.
These findings suggest that PBM as a therapy for improving reproductive outcomes is addressing one of the fundamental causes of infertility: oxidative stress.
Why This Matters for Women With Fertility Issues.
For women going through the often stressful and difficult process of infertility, PBM provides a hopeful solution. PBM reduces oxidative stress in granulosa cells, creating a healthier environment for eggs to flourish. Here’s why:
Better Egg Quality: By lowering oxidative stress and boosting mitochondrial activity, PBM can improve egg health and increase the chances of successful conception.
Natural Hormonal Balance: Granulosa cells manage key hormones such as estrogen, and PBM's protective actions can help them perform this important function.
Gentle and Non-Invasive: Unlike many fertility procedures, PBM is non-invasive, making it an excellent supplement to IVF or IUI.
Broader Health Benefits: PBM has the potential to promote overall reproductive health by supporting cellular health at the basic level, particularly for women suffering from PCOS or endometriosis.
