The sperm banks, in China, sent out WeChat messages to followers that offered potential donors just short of the cash equivalent of the latest Apple gadget.
The users of the social network received a message called ' New ways to get an iPhone 6s ' with an image of the much sought-after phone.
It read: "The bank is seeking donors aged 22 to 45, each to receive £503, while the iPhone 6s is priced at £535 on the mainland."
Hubei Human Sperm Bank in central China sent out their message on Monday, followed by Shanghai Human Sperm Bank at Renji Hospital, the latter of which has been read more than 400,000 times.
According to China Daily , a student named Li said that his roommate was tempted, while another, called Wang, felt like it wasn't a bad idea, just a new tactic.
A Dr Zhu from Hubei's sperm bank, said they'd been struggling to get new donors and the marketing is a new trick, but he says they're targeting adults who can make their own decisions.
