The Sunday Times found this advertisement on the Singapore-based classifieds website, www.inkiti.com, yesterday, and called the Indonesian number listed.
Sounding friendly, the man who answered the phone confirmed that he had put up the ad and requested to be known only as MM.
He said he was from Jakarta, and had put up the ad in December last year, one on inkiti and another on an Australian site.
It was partly out of desperation, he said in English.
'I was in a situation at the time and my family was facing financial problems. That was when I thought I might sell my kidney.'
He said that he explicitly specified 'no broker' so as to sieve out opportunists who might take advantage of his offer.
Following the posting, he did some research on the after-effects of donating one's kidney.
'Along the way, I actually read some articles on the Internet that talked about people's good spiritual experiences with kidney donations. I was touched when I read those stories,' he said.
Soon after placing the ad, however, his life took a turn for the better when he found a new job in a recruitment agency.
He claimed that he did not have a price in mind when he made the posting and has since had a change of heart.
'I've changed my mind about wanting to sell my kidney and I'm willing to give it away to anyone who needs it if they just contact me,' he claimed.
He added that it would be his 'dream' to 'experience the spiritual fulfilment of helping someone in this way'.
To date, he has not received any replies to his postings.
