How Scandinavian Fertility Clinics Are Using Red Light Therapy and What It Means for Reproductive Medicine

While Red Light Therapy has gained mainstream attention in wellness and sports recovery, some of the most compelling clinical applications have been quietly developing in reproductive medicine — particularly in Scandinavia, where fertility clinics have been integrating Photobiomodulation (PBM) into assisted reproduction protocols since 2012.

At AURORA Biomodulation Center in El Born, Barcelona, we have been following this research closely. It forms a core part of the scientific foundation behind our fertility protocol — and it is why we are now actively engaging with fertility clinics in Spain to explore collaborative protocols for their patients.

The Scandinavian data: a remarkable starting point

Since 2012, a group of clinics in Denmark and Norway began using PBM systematically with patients experiencing fertility challenges. The results, documented by Arne Grinsted and published in EC Gynaecology, are striking: of approximately 400 women treated — all of whom had already exhausted conventional approaches including dietary intervention, hormonal treatments, IUI, IVF and ICSI — 260 achieved pregnancy. That represents a success rate of approximately 65%.

These were not easy cases. Many of these women had, in the words of the researchers, "given up hope of ever conceiving." The typical time to pregnancy following PBM treatment was one to three months. The conclusion drawn was that PBM offers a natural and non-invasive treatment option for women facing reproductive health issues, with no side effects.

Why does PBM work for fertility? The cellular mechanism

The mechanism is well established in the scientific literature. PBM light — delivered at specific red and near-infrared wavelengths — penetrates tissue and is absorbed by mitochondria, the energy-producing structures inside every cell. This stimulates increased production of ATP, the cellular energy currency, and reduces oxidative stress.

This matters enormously in reproductive medicine because egg cells and sperm cells are among the most energy-dependent cells in the human body. Mitochondrial function is directly linked to oocyte quality — the energy available to an egg during fertilisation and early embryonic development is a critical determinant of IVF success.

Recent clinical evidence — 2024

The evidence base is growing rapidly. A 2024 randomised clinical trial published in the Journal of Lasers in Medical Sciences evaluated PBM in women with recurrent implantation failure — one of the most challenging scenarios in IVF. The study found meaningful improvements in endometrial receptivity and pregnancy outcomes. You can access the full study here: LLLT for Recurrent Implantation Failure — PMC

A further prospective case series published in the Journal of Clinical Medicine in November 2024 documented three women with complex fertility histories — multiple failed IVF cycles, miscarriages, unexplained infertility — who received multiwavelength PBM treatment. All three achieved successful pregnancies and healthy live births. One conceived naturally following PBM after years of failed assisted reproduction.

A 2025 case report published in Photonics documented a 27-year-old woman with PCOS, endometriosis and low ovarian reserve who had failed to conceive naturally for six years and had one unsuccessful IVF cycle. Following a course of PBM treatments, she achieved a healthy live birth. Full paper: PBM in Complex Female Infertility — Photonics

Male fertility: an equally important dimension

The evidence for PBM and male fertility is particularly consistent. Multiple studies have documented improvements in sperm motility, morphology and DNA integrity following PBM treatment. Given that male factor infertility contributes to roughly half of all fertility challenges, this is a dimension that deserves equal attention in any integrative reproductive medicine protocol.

What AURORA offers

AURORA Biomodulation Center is Spain's pioneering full-body PBM center, operating in El Born, Barcelona since 2023. Our medical-grade full-body pods deliver five clinically studied wavelengths simultaneously — 633nm, 660nm, 810nm, 850nm and 940nm — producing a systemic effect that localised panel devices cannot replicate.

For fertility clients, we offer an 8 to 12 week protocol, completely non-invasive and drug-free, designed to be fully compatible with any medical reproductive treatment in progress including IVF, ICSI and IUI. There are no known contraindications with fertility medications.

AURORA is uniquely positioned to bring this Scandinavian model to Spain for the first time — and we welcome dialogue with reproductive medicine specialists who share an interest in integrative approaches to fertility care.

For fertility clinics and reproductive medicine specialists

If you are a clinician working in reproductive medicine and wish to learn more about our protocol and the clinical evidence base, we would welcome a conversation. We have prepared a full clinical dossier including protocol documentation and scientific references which we are happy to share.
