Medical and formal term for giving birth to more than one baby at a time (twins, triplets, etc.).
I received an explanation from the doctor about the risks of multiple births.
In fertility treatment, the possibility of multiple births can increase.
Refers specifically to twins, while 多子出産 is the broader medical term for any multiple birth.
General term for childbirth; 多子出産 specifies multiple births.
Compound of 多子 (たし, 'many children') and 出産 (しゅっさん, 'childbirth'). The exact historical derivation is uncertain; the term is used in modern medical contexts.
