- Synonym自然流産しぜんりゅうざんWrittenWritten medical term for a miscarriage occurring naturally, with no artificial cause; 「流産」 itself can also figuratively describe a plan that comes to nothing.
- Related死産しざんWrittenWritten term for delivering a fetus that has died, counted in Japan from 12 weeks; cases from 12 to under 22 weeks overlap with 「流産」, so the boundary is not clean.
- Related堕胎だたいWrittenWritten term for artificially aborting a fetus, carrying legal and ethical overtones; 「流産」 is a natural event.
- Related中絶ちゅうぜつNeutralNeutral term, common in speech, for an induced abortion; it also means stopping or interrupting something midway, which 「流産」 does not.
- Related妊娠中絶にんしんちゅうぜつWrittenWritten term for the artificial termination of a pregnancy; 「流産」 by contrast usually means a natural miscarriage.
- Antonym出産しゅっさんNeutralNeutral word for childbirth or delivery; the direct opposite of 「流産」.
- Antonym分娩ぶんべんWrittenWritten medical term for the delivery of the fetus; it contrasts with 「流産」 only in the outcome of the birth, and is not a strict antonym.
Use 「流産」 for a pregnancy ending before 22 weeks, or figuratively for a plan that fails, as in 「計画が流産する」. For an induced abortion use 「中絶」; for delivering a fetus that has died, 「死産」; for a normal birth, 「出産」.
