"Human reproduction admits of choice," says Hsieh Fon-jou, who practices as an obstetrician at National Taiwan University Hospital (NTUH). He notes that before the 24th week an embryo lacks a heartbeat and isn't regarded as a person yet. Consequently, one method often used for those having trouble conceiving is to implant three or four fertilized eggs into the womb to increase the chances of at least one surviving.
「人類的生殖應是容許選擇的，」台大婦產科醫師謝豐舟指出，在醫學界定中，24 週以前的胚胎尚無心跳，還不算「人」，因此不孕症治療中常見的、先在子宮內植入 3 ∼ 4 胎，以增加成功率，之後再行「減胎」，在醫界看來並非墮胎或殺生。
