Regenerative medicine is reshaping the boundaries of what is clinically possible across virtually every domain of human health— reproductive medicine is no exception. For individuals whose fertility has been compromised by age-related ovarian decline, premature ovarian insufficiency, or other conditions that diminish the biological capacity of reproductive tissue, the conventional options have historically been limited. A new and compelling category of intervention is beginning to challenge that paradigm.
At The Longevity Centers, we offer VSELs Therapy, which utilizes very small embryonic-like stem cells activated through advanced laser guidance. It is one of the most sophisticated and promising regenerative approaches currently available for fertility and reproductive health support. The difference is that our VSELs therapy is designed to work with your body’s own innate reproductive capacity.
What Are VSELs?
Very small embryonic-like stem cells—known clinically as “VSELs”—are a type of adult stem cell that exists naturally within the body’s own tissues. Unlike embryonic stem cells, which are derived from early-stage embryos and carry significant ethical and immunological considerations, VSELs are endogenous, meaning they originate from and remain within the patient’s own biological system throughout their lifespan.1
What makes VSELs remarkable is their embryonic-like character. Despite being present in adult tissue, these cells retain certain properties that allow them to participate in tissue repair and regeneration processes in ways that other adult cells cannot. They are understood to play a role in many of the body’s maintenance and repair mechanisms, functioning as a reserve population of regenerative cells that can be mobilized in response to tissue damage, hormonal signaling, or targeted activation.
In the context of reproductive health, this regenerative potential is of considerable significance. The ovaries—like all tissues—are subject to the cumulative effects of aging, oxidative stress, inflammation, and previous medical interventions. The environment that influences egg quality and ovarian reserve is, at its core, a biological one, which is susceptible to the same degenerative processes that affect tissue throughout the body. VSELs therapy delivers regenerative cells to ovarian tissue with the goals of repair, renewal, and functional restoration—using the body’s own cellular resources to do so.
The VSELs Delivery Process
A defining feature of VSELs therapy at The Longevity Centers is the use of the SONG Laser—an advanced system that plays a central role in both the activation of the stem cells and their precise, targeted delivery to reproductive tissue.
The SONG Laser supports the accurate mobilization of VSELs from the patient’s own cell sample, helping to guide activated stem cells toward the target tissue with a degree of precision that less technologically sophisticated delivery methods cannot achieve. This targeted approach matters enormously in the context of reproductive medicine, where the goal is not merely stem cell circulation but localized regenerative activity within ovarian or testicular tissue.
The VSELs therapy protocol at The Longevity Centers is a structured, multi-stage process designed to maximize both the safety and regenerative efficacy. It centers on the careful collection, preparation, activation, and delivery of the patient’s own cells.
The process unfolds across four principal stages:
- Cell Collection: A small sample of the patient’s own cells is obtained through a minimally invasive blood collection process. Because VSELs are derived entirely from the patient’s own body, there is no requirement for donor material, and the risk of immunological rejection or adverse systemic reaction is exceptionally low.
- Activation: The collected sample is exposed to the SONG Laser, which supports the activation and mobilization of stem cells within the sample. This stage is critical to ensuring that the cells delivered to reproductive tissue are in an optimal state for regenerative engagement.
- Targeted Delivery: Activated VSELs are guided into the target ovarian or testicular tissue under appropriate clinical oversight. The precision of the SONG Laser-assisted delivery process supports accurate localization of regenerative cells where they are most needed.
Regenerative Support: Once delivered, can VSELs help stimulate the natural repair and rejuvenation processes of the target tissue, potentially improving the microenvironmental conditions that govern follicular health, ovarian reserve, hormonal signaling, and reproductive tissue function.

The Biological Case for VSELs in Reproductive Health
To appreciate why VSELs therapy holds such promise for fertility and reproductive health, it is helpful to consider the biological mechanisms through which reproductive capacity declines, and the ways in which endogenous stem cell activation may address them.
Ovarian Aging and the Depletion of Regenerative Capacity
The ovarian environment is governed by a complex interplay of cells, supporting tissue, vascular networks, and molecular signaling systems that coordinate the development and selection of oocytes for ovulation.2 As a woman ages—and particularly as she approaches perimenopausal transition—this environment undergoes deterioration driven by oxidative stress, reduced blood flow, chronic low-grade inflammation, and the exhaustion of the local cells responsible for tissue maintenance and repair.
Conventional fertility medicine has largely treated this decline as an irreversible biological given, a trajectory to be managed rather than a dynamic state that may be amenable to regeneration. The emerging science of VSELs challenges this assumption. By introducing activated, endogenous stem cells capable of participating in tissue repair, VSELs therapy may support the restoration of biological reproductive conditions.
Hormonal Balance and Ovarian Function
The ovary is an active endocrine organ responsible for the production of estrogen, progesterone, and testosterone in concentrations and rhythms essential to reproductive health, broader hormonal balance, and systemic well-being.3 When ovarian function declines, the hormonal consequences extend well beyond fertility itself, contributing to the full spectrum of symptoms associated with perimenopause and ovarian insufficiency—from mood dysregulation and cognitive changes to cardiovascular risk and skeletal health. VSELs therapy has the potential to support both reproductive function and the broader hormonal environment that impacts a person’s quality of life.
Who May Benefit from VSELs Therapy for Fertility?
Individuals who may see significant benefit from VSELs therapy at The Longevity Centers encompass a range of conditions or reproductive challenges. While a thorough evaluation is always required to determine appropriateness, the following groups are among those most commonly considered for this therapy:
- Women experiencing premature ovarian aging or decline: Those with diminished ovarian reserve or reduced antral follicle counts who are seeking a regenerative approach to restoring ovarian biological activity
- Women with premature ovarian insufficiency (POI): Individuals whose ovarian function has declined earlier than expected and who wish to explore regenerative options before resorting to donor egg pathways
- Men with testicular tissue concerns affecting fertility: VSELs therapy is applicable not only to female reproductive health but to male fertility as well, with targeted delivery to testicular tissue offering potential regenerative support for sperm production and testicular function
- Couples exploring emerging regenerative fertility options: Individuals and couples who have not achieved their reproductive goals through conventional fertility treatments and wish to explore next-generation biological approaches as part of a comprehensive fertility strategy
- Patients seeking a non-donor approach: Those for whom the use of their own biological material—rather than donor cells, eggs, or sperm—is a meaningful priority, whether for personal, ethical, or medical reasons
Individuals interested in proactive reproductive longevity: Patients who wish to support the long-term health and functional preservation of their reproductive tissue as part of a broader longevity and preventive health strategy
Frequently Asked Questions
What are VSELs, and how do they differ from other stem cell therapies?
Very small embryonic-like stem cells are a naturally occurring population of adult stem cells found within the body. What distinguishes VSELs from other stem cell approaches is that they are derived entirely from the patient’s own biological material, eliminating the ethical considerations and immunological risks associated with donor-derived or embryonic stem cell therapies. Their embryonic-like properties give them a degree of regenerative flexibility that other adult cells lack, making them particularly well-suited to applications in tissue repair and reproductive health support.
Is VSELs therapy safe?
Yes, since VSELs therapy utilizes the patient’s own cells throughout the entire process—from collection through activation and delivery—the risk of immune rejection, allergic reaction, or systemic adverse response is exceptionally low. The incorporation of SONG Laser technology supports precise, targeted delivery, further minimizing the risk of off-target effects. As with any regenerative procedure, a thorough clinical evaluation is conducted prior to therapy to ensure appropriateness and to individualize the protocol for each patient’s specific health profile and reproductive goals.
How does the SONG Laser enhance VSELs therapy?
The SONG Laser plays a central role in the VSELs therapy protocol by supporting the activation and mobilization of very small embryonic-like stem cells and guiding their targeted delivery into reproductive tissue. This laser-assisted precision is a meaningful advancement over less technologically sophisticated stem cell delivery methods, ensuring that activated cells are directed to the specific ovarian or testicular tissue environment where their regenerative activity is most needed.
How many VSELs Therapy sessions are typically needed?
The number of sessions appropriate for any individual patient depends on the specific clinical indication, the severity of ovarian or reproductive tissue decline, and the patient’s response to initial therapy. Your experienced care team at The Longevity Centers will conduct a comprehensive assessment before therapy begins and will monitor your biological response—through hormonal markers, ultrasound parameters, and clinical evaluation—to guide decisions about additional sessions and protocol adjustments over time.
Can VSELs therapy be combined with IVF or other fertility treatments?
Yes, VSELs therapy is well-suited to integration with conventional assisted reproductive technologies, including IVF, where it may be applied to improve ovarian response, egg quality, or endometrial receptivity. It may also be combined with other regenerative therapies — including PRP therapy—for a more comprehensive approach to reproductive tissue optimization. Your care team will coordinate the timing and sequencing of VSELs therapy with any concurrent fertility protocols to ensure a cohesive and well-integrated plan.
