Công nghệ giúp cho cuộc sống của con người trở nên dễ dàng và thoải mái hơn, nhưng đồng thời nó cũng gây ra những nguy cơ tiềm ẩn về sức khoẻ cho chúng ta.

Nếu như bạn đang thở phào nhẹ nhõm vì những nghiên cứu gần đây cho thấy sóng điện thoại không gây ra ung thư, thì bạn, đặc biệt là các đấng mày râu, hãy cẩn thận với một "kẻ thù giấu mặt" khác: WiFi. Một nghiên cứu mới đây thực hiện ở Argentina kết luận rằng sử dụng máy tính có kết nối WiFi khi đang đặt máy trên đùi có thể dẫn đến hậu quả suy giảm chất lượng tinh trùng ở nam giới.

Nghiên cứu được tiến hành với sự tham gia của 29 tình nguyện viên. Các nhà nghiên cứu lấy mẫu tinh trùng của 29 người này, sau đó đặt chúng vào một chiếc đĩa được để phía dưới một chiếc máy tính đang tải dữ liệu thông qua WiFi. Thử nghiệm kéo dài trong vòng 4 giờ, và kết quả được so sánh với một nhóm tinh trùng khác được đặt trong cùng nhiệt độ nhưng cách xa máy tính (nhóm kiểm soát). Sau khi kết thúc thời gian, các mẫu thử được đặt dưới kính hiển vi để xác định trạng thái vận động của tinh trùng. 

Kết quả là có đến 25% tinh trùng thuộc nhóm mẫu có tiếp xúc với sóng WiFi ngừng vận động, so với kết quả của nhóm kiểm soát là 14%. Không những thế, 9% số tinh trùng của nhóm thử nghiệm cho thấy có sự hủy hoại về ADN, gấp 3 lần con số của nhóm kiểm soát. Conrado Avendano, một thành viên thuộc nhóm nghiên cứu, cho rằng phát xạ điện từ từ quá trình giao tiếp không dây chính là nguyên nhân gây nên sự suy giảm số lượng tinh trùng còn sống trong thí nghiệm trên. "Dữ liệu của chúng tôi chỉ ra rằng việc sử dụng một máy tính xách tay có kết nối WiFi và đặt máy ở gần bộ phận sinh dục nam có thể làm suy giảm chất lượng tinh trùng", trích báo cáo của nhóm nghiên cứu. "Hiện tại, chúng tôi chưa xác định được liệu hiện tượng này có xảy ra đối với tất cả các sản phẩm laptop có kết nối WiFi hay không, và những điều kiện gì có thể gia tăng mức độ của hiện tượng này".

Mặc dù đây chỉ mới là nghiên cứu ban đầu, và còn nhiều việc khác cần phải làm trước khi đưa ra được một kết luận tổng quát, nhưng các đấng mày râu cũng nên chú ý thay đổi thói quen sử dụng 
laptop của mình đi là vừa. Cẩn tắc vô ưu mà!
