Deciding when to move from “still trying” to “let’s get this evaluated” is one of the harder judgment calls in reproductive health, mostly because the honest answer is “it depends on your age and history.” This page lays out the general timing guidance clinicians use, so you have a framework for that decision.
The General Timing Guidance
The American Society for Reproductive Medicine (ASRM) recommends that, for couples having regular, unprotected intercourse without a known reproductive issue, a fertility evaluation should generally begin:
- After 12 months of trying, if the female partner is under 35.
- After 6 months of trying, if the female partner is 35 or older.
- Without delay, at any age, if there’s a known condition affecting fertility, or if the female partner is over 40.
The age-based difference in timing reflects how fertility changes over time on a population level, not a judgment about any individual’s situation — some people conceive quickly at 38, and some take longer at 28. The guidance exists to make sure age doesn’t become a reason to delay evaluation unnecessarily.
Reasons Not to Wait, Regardless of Age
Certain situations are recognized reasons to seek evaluation sooner than the standard timeline, including:
- Irregular or absent menstrual cycles.
- A known or suspected condition affecting the uterus, fallopian tubes, or pelvis, including endometriosis.
- A known or suspected male-factor fertility issue.
- A genetic condition known to affect fertility.
- Prior cancer treatment (chemotherapy or radiation) that can affect reproductive function.
If any of these apply to you or your partner, it’s reasonable to bring it up with a provider well before the general 6- or 12-month timeline.
What a Fertility Evaluation Generally Involves
In broad terms, a fertility workup typically looks at ovulatory function, the structure of the reproductive tract, and semen quality for a male partner, since both female-factor and male-factor causes are common contributors to difficulty conceiving. Because both partners can contribute to the picture, parallel evaluation of a male partner is a standard part of the process when applicable, not an afterthought. The specific tests used depend on your history and what a provider identifies as relevant — this page describes categories, not a personalized testing plan.
