Healthy young males in central China's Hubei province craving an iPhone 6S, but lacking the funds, have a new way to make some quick cash - by donating sperm.

"An iPhone 6S costs at least 5,288 yuan ($830) on the Chinese mainland, and now you can easily own one without having to sell a kidney. Hubei Province Human Sperm Bank wants you to own a 6S," the sperm bank says in an advertisement posted on WeChat, a popular messaging app.

According to the promotion, headlined "A new plan to buy an iPhone 6S", a donor will be paid 5,000 yuan for 40 milliliters of semen, meaning he needs only another 288 yuan to get a phone.
