Male reproductive health is rapidly declining during the past decades and it is well known that scrotal temperature is linked to male infertility.
We performed a prospective data evaluation within a counterfactual analysis study design. Scrotal cooling was performed using Snowballs™ underwear, scrotal temperature was monitored using a wireless temperature sensor (SensorPush, Brooklyn, NY, 11215).
Overall, scrotal skin temperatures were monitored for 1008 hours. Median scrotal skin temperature was 34.6°C (IQR 33.1 to 35.3) and 35.3°C (IQR 34.4 to 35.9) in the experimental (SnowWedge™) period and control period, respectively, which was significantly different (P <0.001).
Cyclic scrotal skin cooling using specialized underwear is feasible and efficacious without impairing the activities of daily living and reduces median scrotal skin temperature significantly by 0.7°C. Given the proven association of scrotal skin temperature and semen quality, cyclic scrotal skin cooling by a device such as Snowballs™ underwear may eventually increase semen quality and fertility.
在过去几十年中，男性生殖健康正在迅速下降，并且众所周知，阴囊温度与男性不育症有关。
我们在一项反事实分析研究设计中进行了前瞻性数据评估。使用Snowballs™内衣进行阴囊降温，使用无线温度传感器（SensorPush，纽约布鲁克林，11215）监测阴囊温度。
总体而言，共监测阴囊皮肤温度1008小时。在实验（SnowWedge™）期和对照期，阴囊皮肤温度中位数分别为34.6°C（四分位间距33.1至35.3）和35.3°C（四分位间距34.4至35.9），差异有统计学意义（P<0.001）。
使用特制内衣进行周期性阴囊皮肤降温是可行且有效的，不会影响日常生活活动，并使阴囊皮肤温度中位数显著降低0.7°C。鉴于阴囊皮肤温度与精液质量之间已证实的关联，通过Snowballs™内衣等设备进行周期性阴囊皮肤降温最终可能会提高精液质量和生育能力。
