A wearable that fits around the penis, claimed to be the first men’s healthcare device to use photobiomodulation therapy (PBMT), has been launched along with claims that it improves sperm count and mobility, plus erectile function.
The Kaisar is a horseshoe-shaped gadget that sells in the US for $239 and features 40 LED lights, to administer PBMT, also known as LED or light therapy.
PBMT can also be known as low-level laser therapy, and has been used for pain relief and to reduce inflammation. Its mechanisms are still not fully understood by the scientific community, although recent studies have shown that it can improve the movement ability of sperm.
A 2023 study called Effects of Photobiomodulation Therapy on Human Sperm Function, published in the National Library of Medicine, found that research participants who received PBMT had sperm with significantly increased motility. The study concluded that PBMT was an “efficient” way to improve sperm function.
You use the Kaisar by wearing it over your penis for 15 minutes per day, exposing your genitals to its LEDs. The device is 96 millimeters at its longest section and weighs 104 grams.
The Kaisar company, which is based in South Korea, told SEXTECHGUIDE that research it conducted in 2023 showed that mice given controlled exposure to the device’s LED technology showed increased sperm motility and blood flow, compared to control group mice.
This improved blood flow led to claims that the Kaisar can increase erection function in humans, based on better blood flow meaning a harder penis. However, Kaisar is yet to test the product on humans in large research trials, which would be required to ascertain whether it is indeed “the solution for your sexual complaints”, as the firm claims it to be.
Still, attempting to utilize PBMT in a home-use device is an interesting development, and the company says it will conduct further research.
Some men who have had PBMT in medical settings have previously reported improvements in their erections and their sexual desire.
Generally, medical professionals agree that more research into PBMT in general is required to understand its effectiveness for sexual issues – whether it’s administered using a wearable device or in a hospital.
