29-year-old Tracy Kiss has been drinking the interesting concoction for the past month, saying it’s boosted both her mood and her immunity.
The mum-of-two is currently single, so harvests her sperm from her best friend – or rather, he harvests it and delivers it to her up to three times a week.
Tracy – who’s vegan – stores it in tubs in the fridge with the rest of her groceries.
The mum-of-two from Buckinghamshire then whizzes the batch up into a smoothie, with complementary ingredients such as bananas, seeds and almond milk.
‘I’d been feeling run down and had no energy, but now I’m full of beans and my mood has improved,’ says Tracy.
