透過Wi-Fi使用筆電上網影響精蟲質量

來自美國第一個試管嬰兒發源地– Eastern Virginia Medical School, Norfolk, Virginia的研究

摘要

目的：

為了評估筆記型電腦連接到無線局域網（WI – FI）對人類精子的影響。

設計：

在體外研究的前瞻性。

背景：

生殖醫學中心。

病人（S）：

來自29名健康捐贈者的精液樣本。

干預（S）：

由游泳活動精子被選中。每個精子懸液分為兩個等分。一個精子從每個病人（實驗）等分暴露的Wi – Fi互聯網連接的筆記本電腦4小時，而第二等份（未曝露）是不被暴露在筆記本電腦的控制，在相同條件下培養。

主要觀察指標（S）：

精子的活動力，生存能力和DNA破裂片段的評價。

結果：

捐助者的精子樣本，大多精蟲正常，暴露在4個小時的體外的無線互聯網連接

的筆記本電腦表現出顯著進步的精子活力下降，精子DNA碎片增加。死精子的水平，顯示兩組間無顯著性差異。

結論（S）：

據我們所知，這是第一次研究，以評估使用筆記本電腦對人類精子的直接影響。前體內的人類精子接觸到無線互聯網連接的筆記本電腦減少由非熱效應的活力和誘導的DNA碎片。我們推測，保持無線連接上互聯網圈附近的睾丸一台筆記本電腦，可能會導致男性生育能力下降。需要進一步在體外和體內研究證明這一論點。

陳啟煌醫師的觀點:

男人的精蟲標準值又下修了。世界衛生組織（WHO）最近再修正男性精蟲正常值，從每西西兩千萬隻下修到一千五百萬隻。男人的平均精蟲數在塑化劑、嗑藥、喝酒、吸菸、肥胖、生活壓力等影響下，逐年遞減。現在電磁波如影隨行在文明的進化中傷害男性。智慧型手機在腰間及口袋及筆電放在大腿上很接近睪丸的電磁波效應，可說男性透過Wi-Fi上網很愉快，也很傷害。

Abstract

OBJECTIVE:

To evaluate the effects of laptop computers connected to local area networks wirelessly (Wi-Fi) on human spermatozoa.

DESIGN:

Prospective in vitro study.

SETTING:

Center for reproductive medicine.

PATIENT(S):

Semen samples from 29 healthy donors.

INTERVENTION(S):

Motile sperm were selected by swim up. Each sperm suspension was divided into two aliquots. One sperm aliquot (experimental) from each patient was exposed to an internet-connected laptop by Wi-Fi for 4 hours, whereas the second aliquot (unexposed) was used as control, incubated under identical conditions without being exposed to the laptop.

MAIN OUTCOME MEASURE(S):

Evaluation of sperm motility, viability, and DNA fragmentation.

RESULT(S):

Donor sperm samples, mostly normozoospermic, exposed ex vivo during 4 hours to a wireless internet-connected laptop showed a significant decrease in progressive sperm motility and an increase in sperm DNA fragmentation. Levels of dead sperm showed no significant differences between the two groups.

CONCLUSION(S):

To our knowledge, this is the first study to evaluate the direct impact of laptop use on human spermatozoa. Ex vivo exposure of human spermatozoa to a wireless internet-connected laptop decreased motility and induced DNA fragmentation by a nonthermal effect. We speculate that keeping a laptop connected wirelessly to the internet on the lap near the testes may result in decreased male fertility. Further in vitro and in vivo studies are needed to prove this contention.
