Infertility has reached record-high levels with one in six people affected globally. Some nations experience it at higher numbers prompting governments to intervene in hopes of boosting declining birth rates. Consequently, the demand for fertility treatments such as IVF, IUI, hormonal and drug approaches, and surgical procedures are also increasing. However, these treatments can be too costly, stressful, and laden with side effects. But what if there is an alternative approach?
For years now, red light or near infrared light therapy has demonstrated significant potential in enhancing fertility in both men and women. In this article, ROJO Light Therapy US will explore the underlying causes of rising infertility rates and how light therapy could play a key role in addressing this issue.
Until 1965, the average woman worldwide had up to five children. Today, that number is down by half globally, with women having fewer than 2.5 children. In Australia, the fertility rate is even lower with projections indicating Australians are likely to have only up to 1.6 children over the next five years.
Part of the reason for this decline is socioeconomic factors such as couples choosing to delay parenthood. Another reason is dietary, hormonal, and environmental factors. Research shows that there has been a 50% decline in sperm counts among men over the past 40 years alongside an increase in female reproductive disorders such as polycystic ovarian syndrome (PCOS) and endometriosis.
To address low birth rates resulting from infertility, some countries are taking proactive measures, offering incentives or medical treatment to those willing. The Japanese government, for instance, is offering to pay for a couple’s IVF treatment as part of their efforts to deal with the unfolding population crisis. Meanwhile, in Hungary, lifelong income tax exemptions are offered to women with four or more children. Despite these efforts, the broader issue calls for more accessible solutions.
When using near-infrared light therapy to address female fertility concerns, the main target areas are the ovaries, uterus, fallopian tubes, and general hormone systems. A specific wavelength is also required for the near-infrared light to penetrate deep enough and interact with the cells of these tissues and organs. In past studies, researchers found the 830 nm wavelength to be the most potent for fertility enhancement.
In a study from Denmark, near infrared light therapy was applied directly to the abdomen of 400 infertile women in large doses per session. If the woman was unable to conceive in her current menstrual cycle, the treatment continued until the next with three sessions applied each week. Remarkably, out of that 400, 260 were able to conceive following the treatment.
Applying light therapy directly to the abdomen works in two ways. First, it helps ensure the optimal function of the reproductive system, ensuring egg cells are released during ovulation and smoothly travel down the fallopian tubes before implanting into a healthy uterus wall. Second, it enhances the health of egg cells which use 200 times more energy than other cells in the body. During near-infrared light therapy, light photons interact with the cell’s mitochondria, encouraging the production of adenosine triphosphate (ATP), the cell’s primary fuel. This boost provides egg cells with the necessary energy to accommodate the processes for cell division and growth.
In 2012, Japanese researchers explored the effects of 830 nm light therapy on infertile Japanese women by applying it to their necks. The aim was to enhance hormonal and metabolic actions through the direct and indirect effects of the treatment on the brain. The results were uplifting with nearly 22% of the women conceiving and 68% of them achieving live births.
Male infertility is often linked to issues affecting testicular function. leading to a sperm-related problem. Other problems are related to hormone imbalances, blockages in the male reproductive organs, and lifestyle factors. Red light therapy for male infertility focuses on the first one.
Evidence suggests that light therapy significantly improves sperm motility or the swim efficiency of sperm. With low motility, the sperm wouldn’t be able to get through the female’s cervical mucus to reach the egg cell. Additionally, light therapy has been proven to enhance sperm counts or concentration at least two to five times by promoting the proliferation of Sertoli cells in the testicles which are responsible for sperm production.
Near infrared light therapy presents an accessible and innovative solution for couples who are struggling with fertility, but are keen on growing their family. However, while plenty of research supports the beneficial effects of the treatment for both men's and women’s fertility, further study would be more valuable to fully grasp its mechanisms and amplify its efficacy. If you’re interested in exploring the benefits of light therapy, we at ROJO Light Therapy offer a wide range of red light therapy panels for home use. Feel free to contact us for any questions!
