## Abstract

Light stimulation systems and methods for elevating testosterone levels in male patients.

## Claims

### Claim 1

A light stimulation method comprising:
positioning a wearable structure carrying light emitters proximate to testes of a patient, where the wearable structure carrying light emitters emits at least one selected wavelength between 400 nm and 850 nm;
actuating the light emitters in a duty cycle consisting of an ON and OFF sequence wherein ON intervals total at least 5 minutes in at least a 30 minute period; and
providing an irradiance in the range of 20 mW/cm2 to 200 mW/cm2 to the patient's testes where such irradiance enhances testosterone levels in the patient.

### Claim 2 (depends on 1)

The light stimulation method of claim 1 wherein the irradiance is from 50 mW/cm2 to 150 mW/cm2.

### Claim 3 (depends on 1)

The light stimulation method of claim 1 wherein the irradiance is from 80 mW/cm2 to 120 mW/cm2.

### Claim 4 (depends on 1)

The light stimulation method of claim 1 wherein the light emitters comprise LEDs carried in a substrate.

### Claim 5 (depends on 1)

The light stimulation method of claim 1 wherein the light emitters comprise side-emitting optical fibers carried in a fabric.

### Claim 6 (depends on 5)

The light stimulation method of claim 5 wherein the side-emitting optical fibers are detachably coupled to at least one LED.

### Claim 7 (depends on 5)

The light stimulation method of claim 5 wherein the fabric is separate from the wearable structure.

### Claim 8 (depends on 5)

The light stimulation method of claim 5 wherein the fabric is integrated in the wearable structure.

### Claim 9 (depends on 1)

The light stimulation method of claim 1, further comprising using a controller to modulate operating parameters of the light emitters.

### Claim 10 (depends on 9)

The light stimulation method of claim 9, wherein actuating the light emitters includes using the controller to control the irradiance in the duty cycle consisting of the ON and OFF sequence wherein the ON intervals total at least 5 minutes over at least a 30 minute period.

### Claim 11 (depends on 10)

The light stimulation method of claim 10, wherein the ON and OFF sequence includes an ON interval ranging from 1 millisecond to 30 minutes and an OFF interval ranging from 1 millisecond to 10 minutes.

### Claim 12 (depends on 9)

The light stimulation method of claim 9, further comprising utilizing the controller to modulate the operating parameters of the light emitters in response to signals from a temperature sensor.

### Claim 13 (depends on 12)

The light stimulation method of claim 12, wherein the operating parameters include (i) the at least one selected wavelength, (ii) the irradiance, and (iii) the duty cycle.

### Claim 14 (depends on 1)

The light stimulation method of claim 1, further comprising connecting the light emitters to a wearable module carrying a controller and a power source.

### Claim 15 (depends on 1)

The light stimulation method of claim 1, further comprising reflecting light emitted by the light emitters toward the testes of the patient with a reflective layer on the wearable structure.
