We all know that a mind-blowing orgasm (tột đỉnh của khoái cảm tình dục) can take us to heady (dễ bốc lên đầu, dễ say) heights. But blindingly good sex can be just that — blinding. Reaching that hotly anticipated climax can actually burst a blood vessel (làm vỡ mạch máu) in your eye (trong mắt) and impair (làm hư hỏng, làm hại) your vision (tầm nhìn). That’s what happened to one unlucky man from Southampton, England — a port city 75 south-west of London.

The 29-year-old went to the hospital after noticing part of his vision was impaired in his left eye. He told doctors he had “vigorous sexual intercourse (giao hợp, giao cấu)” the night before, but he hadn’t noticed the problem with his sight until the next morning.

...“During orgasm the valsalva manoeuvre [holding your breath to prevent an orgasm = bế tinh] can produce a sudden increase in retinal (võng mạc) venous (tĩnh mạch) pressure  (áp suất) resulting in vessel rupture (vỡ, nứt, rách) and haemorrhagic (xuất huyết) retinopathy (bệnh màng lưới),” the British Medical Journal case report noted.
