Translation guide
The concept of fertility in Japanese can refer to the ability to conceive children, the richness of soil, or the productiveness of the mind. The most common and direct translation is 生殖能力 (seishoku nōryoku) for biological fertility, but other terms are used depending on context.
The ability of a person, animal, or plant to produce offspring.
The standard, formal term for reproductive capacity. Used in medical, biological, and general contexts.
Fertility declines with age.
Specifically refers to the ability to conceive or become pregnant. More clinical than 生殖能力.
She was diagnosed with low fertility.
A medical term for fecundity or the ability to become pregnant and carry to term. Used in fertility treatment contexts.

The quality of soil that enables it to provide nutrients for plant growth.
The quality of being highly productive or inventive in ideas.
The average number of children born to a woman over her lifetime.
The English word 'fertility' covers several distinct concepts. In Japanese, there is no single word that encompasses all meanings. Always choose the term that matches the specific context (reproduction, soil, creativity, demographics). Using 生殖能力 for soil fertility would be incorrect.
The soil fertility declined due to continuous cropping.
The soil around here is fertile.
She has a fertile mind.
The technical term for 'total fertility rate' (TFR). Used in official statistics.
The total fertility rate fell below 1.3.
