When should I get a fertility evaluation?
The short answer
Twelve months of trying under 35, six months at 35 to 39, straight away at 40 or over. Reaching the threshold means you qualify — not that something is wrong.
What to know
- ACOG and ASRM use the same thresholds, so this isn't one clinic's opinion.
- Evaluation isn't treatment — it checks ovulation, the uterus and tubes, and a semen analysis.
- Most of it fits inside a single menstrual cycle.
- Guidelines support evaluating sooner with irregular cycles, pelvic surgery, endometriosis, prior loss or a sperm issue.
- You can usually go directly to a reproductive endocrinologist without a referral.
Read the full explanation
There is a clear answer to this, and it's earlier than many people are told.
ACOG and ASRM both use the same thresholds. If you're under 35, an evaluation is recommended after twelve months of regular, unprotected intercourse without pregnancy. If you're 35 to 39, it's after six months. If you're 40 or over, evaluation is recommended right away, without a waiting period.
Those are the standard timelines, and they assume nothing else is going on. Guidelines also support an immediate evaluation, at any age, when there's a known reason: irregular or absent periods, a history of pelvic infection or pelvic surgery, known or suspected endometriosis, a partner with a known sperm issue, or a history of pregnancy loss.
What "evaluation" means
It doesn't mean treatment. It means finding out whether you're ovulating, whether the uterus and fallopian tubes are open and normal, and whether the semen analysis is normal, plus an estimate of ovarian reserve. Most of it can be done within one cycle.
If you're told to wait longer
If you've reached the threshold for your age and you're told to keep trying, it's reasonable to say: "I understand the guidelines recommend an evaluation at this point. Can we start it, or can you help me understand why you'd wait?" You can also go directly to a reproductive endocrinologist; a referral isn't always required.

- If you'd rather wait, can you help me understand why, and what would change it?
