What Does Subfertility Mean?
Based on Ichhori (March 2023), with updated clinical clarity.
Definition
Subfertility refers to a decreased level of fertility characterized by a longer-than-usual time to conceive, even when having regular, unprotected sex. Unlike infertility, conception is still possible—just more delayed. ([source](https://www.ichhori.com/2023/03/what-does-subfertility-mean.html))
How Subfertility Differs from Infertility
- Subfertility: Conceiving takes longer than typical (often 6–12 months), but spontaneous pregnancy remains possible. ([turn0search2], [turn0search6])
- Infertility: Defined as the inability to conceive naturally after 12 months (in women under 35) or 6 months (over 35) of regular unprotected intercourse. ([turn0search6], [turn0search21])
When to See a Specialist
Experts recommend seeking evaluation if you're under 35 and have tried without success for over a year, or if you're over 35 and it's been over 6 months. ([turn0search21])
Why Understanding the Difference Matters
Recognizing subfertility helps manage expectations, guide testing, and prevent unnecessary stress. While many subfertile couples conceive naturally within time, early assessment can address underlying causes effectively.
