Phototherapy is a useful therapy for many dermatologic disorders and is known for its low side-effect profile. However, one potential notable side effect is genital skin cancer. Unfortunately, no standards for genital protection currently exist for this preventable complication. Patients treated with phototherapy may already have a decreased quality of life because of their primary dermatologic disorder. Development of squamous cell carcinoma of the genitalia may certainly further affect the quality of life.
The objective was to determine which readily available materials afford the best photoprotection of the male genitalia.
Seven common materials used in phototherapy units for genital protection were placed over ultraviolet (UV) B and UVA monitors and placed in broadband UVB, narrowband UVB, and UVA full-body units. The percentage of light blocked was then calculated.
Blue and white cotton underwear, blue surgical towels, an athletic supporter with or without a cup, and the psoralen plus UVA pouch provided acceptable means of genital protection; however, surgical masks did not.
Only the most commonly used materials were tested in the phototherapy units. The materials were not of a single material type or similar masses. In addition, only one of each type of full-body phototherapy unit was used to obtain the data.
Although a polyester composition provides better UV protection, factors such as low porosity and higher mass are intrinsic to decreasing the amount of UV penetration of any fabric. Of the commonly used objects, surgical masks do not provide sufficient protection to the genital area.
光疗是治疗许多皮肤病的有效疗法，以其低副作用为特点。然而，一个潜在的显著副作用是生殖器皮肤癌。不幸的是，目前对于这种可预防的并发症，还没有生殖器保护的标准。接受光疗的患者可能已经因为他们的主要皮肤病而降低了生活质量。生殖器鳞癌的发生肯定会进一步影响生活质量。
目的是确定哪些现成的材料能为男性生殖器提供最好的光保护。
将光疗器中用于生殖器保护的七种常见材料放在紫外线（UV）B 和 UVA 监测器上，并放置在宽带 UVB、窄带 UVB 和 UVA 全身器中。然后计算被阻挡的光的百分比。
蓝色和白色棉质内衣、蓝色手术巾、有或没有杯垫的运动支撑物，以及补骨脂素加 UVA 袋，为生殖器提供了可接受的保护手段；然而，手术口罩则不行。
仅在光疗器中测试了最常用的材料。这些材料不是单一的材料类型或相似的质量。此外，为了获取数据，仅使用了每种全身光疗器的一个。
尽管聚酯成分提供了更好的紫外线保护，但任何织物的紫外线穿透率降低都与低孔隙率和更高的质量等因素有关。在常用物品中，手术口罩不能为生殖器区域提供足够的保护。
