Translation guide
The act or process of making pregnant; fertilizing an egg. In Japanese, this is typically expressed with specific verbs or nouns depending on context, such as biological fertilization, deliberate impregnation, or metaphorical saturation.
The process of sperm fertilizing an egg, leading to pregnancy.
The standard biological term for fertilization. Used in medical and scientific contexts.
In vitro fertilization was successful.
Conception; the moment when a woman becomes pregnant. Slightly more formal or literary than 受精.
I heard the news of conception.
The act of making someone pregnant, often with intent or in a specific context (e.g., breeding, fantasy).
Literally 'to make pregnant'. The most direct and common way to express deliberate impregnation.
He got her pregnant.
A more visceral or colloquial term for impregnating, often used in fiction or informal speech. Can carry a rough or animalistic nuance.
I want to knock her up.
Literally 'seeding', used for animal breeding or in vulgar/fetish contexts for humans. Very direct and not suitable for polite conversation.
Extremely crude when applied to humans; avoid in formal or polite settings.
The act of saturating or infusing something with a substance or quality, as in 'impregnating wood with resin'.
English uses 'impregnation' as a noun, but Japanese rarely uses a single noun for the act. Instead, use verb phrases like 妊娠させる or 受精する depending on context. The noun 受精 exists but is more about the biological event than the act.
受精 (fertilization) focuses on the union of sperm and egg, while 受胎 (conception) emphasizes the beginning of pregnancy. In medical contexts, 受精 is more common; 受胎 is often used in literary or formal announcements.
