Sex it seems was too much for this man to handle. A man had to be admitted to the hospital after becoming blind in one eye when he orgasmed too hard during sexual intercourse.
According to a story published in the British Medical Journal (BMJ), the 29-year-old presented to the emergency eye clinic reporting an obstruction in the central vision of his left eye, which he noticed that particular morning, while walking.
Doctors guessed that the man performed a Valsalva maneuveur, in other words the tensing of abdominal muscles, straining and holding your breath, in which air is forced against a closed windpipe and pressure increases in the chest.
The pressure created resulted in the popping of blood vessel in the eye of the unfortunate man after his âvigorousâ sexual intercourse, the study said.
The study went on to add that at first the diagnosis was unclear and the patient was asked to return for follow-up three days later. At the second visit, he saw a different clinician who asked direct questions about the patient's sexual activity. The patient then reported an episode of vigorous sexual intercourse on the evening preceding the onset of symptoms.
The doctors then diagnosed him of postcoital valsalva retinopathy. The condition is self-resolving.
Haematologists have also found Valsalva manoeuvre can also produce memory loss.
The intense pressure in the brain's blood vessels resulted in temporary lack of blood flow to the central part of the brain, which in turn, resulted in amnesia, a 1998 study found.
