dr. sugiri. >> we have already changed from big family to small family. in 1970s, our fertility rate was 5.6 children per woman. now it is 2.6 per woman. it's very good in terms of decreasing fertility. but it is not enough. fertility should be 2.1. >> reporter: 2.1, that's replacement rate, is that right? >> yes, that's right. >> reporter: even after that success, the population isn't expected to level off until it reaches some 350 million. and there's one other big question about how much of a role gandarusa will play in lowering that fertility rate: whether or not it gets the approval of islamic religious leaders. some fundamentalist groups are opposed to any form of birth control. but dr. sugiri says, most mainstream imams approve of family planning methods if they are not permanent and do not harm the body. he is optimistic gandarusa will be available in indonesian stores as early as next year. he's less confident the drug will be sold in the united states any time soon, since strict food and drug regulations would require years of additional testing
