When to see a reproductive endocrinologist
How to know it's time to move beyond your OB/GYN.
The simple rule
Under 35 and trying for 12 months without success: see a reproductive endocrinologist (RE). 35 or older and trying for 6 months without success: see an RE. 40 or older: see an RE before you start trying so you have a baseline.
Reasons not to wait
Don't wait the full window if you have: irregular cycles, two or more miscarriages, a known fertility-affecting condition (PCOS, endometriosis, thyroid disease), prior pelvic surgery or infection, or a known male-factor issue. Same-sex couples and single people pursuing donor sperm should also start with an RE rather than an OB/GYN to map out IUI vs IVF strategy from the beginning.
What to expect at the first visit
A 45–60 minute consultation reviewing your history, ordering the full workup, and discussing treatment options at a high level. Most clinics ask both partners (when applicable) to attend. Bring any prior records, a 3–6 month period log, and your insurance card so the financial team can run a benefits check.
