Doctors warn against nighttime sex sessions, because the man suffers life-threatening penile injuries

Doctors have warned against ‘prolonged vigorous’ antics in the bedroom after treating a patient with a potentially fatal injury to his genitals.

The 53-year-old man developed inflammation in the main vein that runs along the shaft of the penis, which can lead to life-threatening blood clots.

He had had a rough sex session with Viagra the night before, which had resulted in extreme swelling on the base of his phallus.

The skin felt warm and ‘soft’, with a visible bulge due to a build-up of moisture.

The man, who has not been named, was treated with anti-inflammatory drugs and made a full recovery within a few weeks, but his doctors are using his case as a warning.

They say doctors should be careful about prescribing Viagra to patients who are likely to have vigorous sex or who have pre-existing damage to their genitals from intercourse.

They reveal the matter in a media report, adding that people should be aware of the “potential risks” of the erectile dysfunction drug.

Approximately 8,000 men in the US suffer a penile injury each year, with penile fractures and trauma from penetration being the most common.

The latest patient was treated in Turkey and his case was revealed in the journal Radiology Case Reports.

The man claimed he had taken Viagra for his erectile dysfunction before having ‘prolonged’ vigorous sex with his partner.

He was officially diagnosed with Mondor disease of the penis, which causes the veins to become inflamed and cause swelling.

The lesion usually appears within hours of prolonged sexual intercourse and causes immune cells to rush to the site of the injury.

This inflammation causes the vein to swell and become painful. It also ensures that the blood clots faster.

The man was diagnosed after an ultrasound, given a course of blood thinners and anti-inflammatories and told to abstain from sex for a few weeks.

In the report, his doctors wrote: ‘Although Mondor disease of the penis is not usually life-threatening, it can significantly affect a patient’s quality of life.

‘Therefore, doctors should remain vigilant about the potential risks of long-term use of sildenafil.

‘They should consider additional predisposing factors, such as vascular injury from sexual activity, when treating and preventing this condition.’
