Episode 92: Restoring Fertility, Hormones and Reversing Menopause Even in Your Late 50’s by Injecting Stem Cells in Reproductive Organs 




BiohackerBlondie Podcast


Restoring Fertility, Hormones, and Reversing Menopause in Your Late 50s with Stem Cells


With Zack Varkaris, Scientific Director of Austin Biotec


In this episode of the BiohackerBlondie Podcast, Jenny Jones sits down with Zack Varkaris, founder of Austin Biotec, to explore one of the most provocative frontiers in regenerative medicine: rejuvenating reproductive organs using stem cells.


The conversation dives into Zack’s pioneering procedure called Rejuvacyte, a therapy designed to restore ovarian function, improve hormone production, and potentially reverse aspects of reproductive aging.


Zack explains how regenerative medicine may allow women to regain hormone levels similar to when they were younger — and why restoring ovarian health could have implications far beyond fertility, including metabolic health, longevity, and quality of life.


The discussion also explores the biology of ovarian aging, stem cell therapies, hormone restoration, and why reproductive health may play a critical role in the future of longevity medicine.


About Zack Varkaris


Zack Varkaris is the Scientific Director of Austin Biotec, a company focused on developing regenerative therapies aimed at restoring reproductive function and improving hormonal health.


Drawing on a background in biology and molecular biology, Zack developed a procedure called Rejuvacyte, which uses stem cell therapies to rejuvenate reproductive organs.


His work focuses on addressing age-related decline in ovarian function and exploring ways regenerative medicine may help restore hormonal balance and fertility.

What is the Rejuvacyte Procedure?


Rejuvacyte is a regenerative therapy designed to rejuvenate ovarian tissue using stem cells.


The procedure focuses on restoring cellular function in reproductive organs, which may help restart hormone production and improve ovarian health.


The core idea is that many of the symptoms associated with aging — particularly menopause — may be related to declining function of reproductive organs and the hormones they produce.


By restoring the health of these organs, it may be possible to improve overall hormonal balance and metabolic health.


Key goals of the procedure include:

• Restoring ovarian function• Increasing hormone production• Improving egg quality• Supporting fertility later in life• Potentially reversing menopause symptoms


Why Ovarian Health Matters for Longevity


One of the major themes of the conversation is that ovaries function as a powerful endocrine organ.


They do far more than simply control fertility.

Healthy ovarian function supports production of key hormones such as:


• Estrogen• Progesterone• Other reproductive signaling molecules

These hormones influence:

• Brain health• Metabolism• Bone density• Cardiovascular health• Skin and tissue integrity

When ovarian function declines, these systems can deteriorate as well.

This is why menopause often coincides with increased risk of:

• Cardiovascular disease• Osteoporosis• Metabolic dysfunction• Cognitive decline

Restoring ovarian function may therefore have broader implications for longevity and overall healthspan.


How Stem Cells Are Used in the Procedure


The Rejuvacyte therapy uses stem cells to stimulate tissue regeneration.

Stem cells are unique because they can:


• Differentiate into different cell types• Release signaling molecules that promote healing• Trigger tissue repair and regeneration

When introduced into aging tissue, stem cells can stimulate:

• Cellular regeneration• Improved blood flow• Activation of dormant cells• Tissue repair processes

In the context of ovarian rejuvenation, this may help restore function to aging reproductive organs.


Reproductive Aging and Egg Quality


Another major topic discussed is the biology of reproductive aging.

Egg quality declines over time due to several factors:


• Mitochondrial damage• DNA mutations• Reduced cellular energy• Oxidative stress

Over time this can lead to:

• Infertility• Hormonal imbalances• Early menopause

Regenerative therapies aim to improve the microenvironment of the ovary, potentially helping restore healthier cellular function.


Fertility in Later Life

While the procedure may support fertility, Zack emphasizes that the goal is not only having children later in life.


The broader goal is improving hormonal health and quality of life.


However, improved ovarian function could theoretically allow women to:

• Improve egg quality• Support fertility later in life• Extend reproductive lifespan

This raises interesting questions about the future of reproductive medicine.


Relationship to IVF


The conversation also touches on how regenerative therapies might complement or improve traditional fertility treatments.

Current fertility treatments like IVF (in vitro fertilization) can help with conception but do not address the underlying health of the ovaries.

Stem cell therapies aim to restore ovarian health itself, which may improve outcomes for fertility treatments.


Potential Implications for Menopause


One of the most fascinating areas of discussion is the possibility of reversing aspects of menopause.

Menopause occurs when ovarian function declines to the point that hormone production stops.

If regenerative therapies can restore ovarian activity, it may be possible to:


• Increase hormone production again• Reduce menopause symptoms• Improve metabolic health• Extend reproductive hormone production

This concept is still emerging but represents a major frontier in regenerative medicine.


Hormones and Whole-Body Health


The episode also explores how reproductive hormones influence the entire body.

Hormones produced by the ovaries impact:

Brain

Estrogen supports neurotransmitters and cognitive health.

Metabolism

Hormones influence insulin sensitivity and fat metabolism.

Bones

Estrogen plays a key role in maintaining bone density.

Skin and tissue health

Hormones influence collagen production and tissue elasticity.

This is why menopause can trigger widespread physiological changes.


The Future of Regenerative Medicine


Stem cell therapies are rapidly expanding across medicine.

Researchers are investigating regenerative treatments for:


• Neurodegenerative diseases• Cardiovascular repair• Anti-aging therapies• Fertility restoration• Hormone rejuvenation

The ability to restore aging tissues may dramatically change how medicine approaches aging.


Rather than simply treating symptoms, regenerative medicine aims to repair underlying biological decline

.

Key Takeaways from the Episode


Reproductive organs are powerful endocrine organs that influence whole-body health.

Declining ovarian function contributes to many symptoms associated with aging.

Stem cell therapies may help restore ovarian tissue and hormone production.

Regenerative medicine may extend reproductive lifespan and improve quality of life.

Hormonal health is deeply connected to longevity and metabolic health.
