Dr Suresh Nair, medical director at Parkway Fertility Centre, said a woman is taking a risk by donating, so deserves to be paid.
"She's subjecting herself to some procedure that's potentially dangerous. How are you going to value that? For a start, it should be those young, healthy women who are not really involved in fertility treatment. For the time being, don't include the fertility couples as yet because they are already burdened."
Singapore's Bioethics Advisory Committee released a report this morning saying women donating eggs for use in stem cell research should only be paid for expenses incurred in making the donation -- such as for transportation or lost wages.
Committee chair Lim Pin said to do any more could turn egg donating into a business.
"We want to make sure that the amount that is reimbursed is not so large that it becomes an inducement."
The donated eggs are used in stem cell research.
