Britain’s currently basking in a heatwave.
And as temperatures could potentially climb to 39C today, some may notice changes to their body.
Feeling flushed and more sweaty is a common side-effect of the warm weather.
But some men are noticing unusual changes to their intimate areas too.
During the hotter months of the year, men feel like their penises have grown larger.
This phenomenon, called summer penis, has been discussed on Reddit in recent years.
On Reddit, one user asked others if they experienced “bigger d*cks in summer and smaller in winter.”
He added: “Anybody notice size fluctuation during the year?
“I know mine is bigger, I have better erections in the summer and I also tend to be more of a shower instead of a grower.
“In the winter, it is the exact contrary. Why is that? More heat = better blood flow?”
The post sparked discussion – and thankfully, a urologist waded in to clear up any confusion.
The expert revealed that while manhoods may look bigger at this time of year, it tends just to be a little bit of bloating.
Speaking to Tracy Moore of MEL Magazine, Orlando urologist Jamin Brahmbhatt said: “Summer or winter, your penis size should remain the same.
“When it’s cold outside, your body does try to maintain its internal heat, and therefore things may appear to be more contracted.
“Blood vessels near the skin contract to maintain the internal heat. However, this type of body heat regulation should not affect the overall size of your penis.”
He added: “When it’s hot outside, your body does try to evaporate the heat through sweat.
“Also when it’s hot outside, you may take in more water, which may in combination with the sweating make it appear like your body or skin is bloated.
“And that may give you the perception that things are larger.”
