💡 Bottom Line Up Front
If you're under 35 and have been trying with well-timed intercourse for 12 months without success, get evaluated. If you're 35–39, seek evaluation after 6 months. If you're 40+, see a specialist when you start trying or within 3 months. Certain symptoms warrant evaluation regardless of how long you've been trying: very irregular or absent periods, known endometriosis, two or more miscarriages, known male factor issues, or a history of pelvic surgery or infections.
The Standard Timeline
| Your Age | When to Seek Evaluation | Why This Cutoff |
|---|---|---|
| Under 35 | After 12 months of trying | Most fertile couples conceive within 12 months; the 12-month mark is the clinical definition of infertility |
| 35–39 | After 6 months of trying | Egg quality decline accelerates; earlier evaluation preserves treatment time |
| 40+ | Immediately or within 3 months | Per-cycle odds are 5–10%; delay reduces success rates significantly |
| Any age with risk factors | Before or when you start trying | Known conditions warrant proactive evaluation |
Red Flags That Mean “Don't Wait”
- Irregular periods: Cycles shorter than 21 days or longer than 35 days, or that vary by more than 7–10 days between cycles, suggest ovulatory dysfunction
- No period at all (amenorrhea): No ovulation = no pregnancy without intervention
- Known endometriosis: Affects tubes, egg quality, and uterine receptivity
- Two or more miscarriages: Warrants recurrent pregnancy loss evaluation
- Known PCOS: May need ovulation induction
- Prior pelvic surgery or ectopic pregnancy: Risk of tubal damage
- History of STIs (especially chlamydia or gonorrhea): Silent tubal damage is common
- Partner has known issues: Previous abnormal semen analysis, undescended testes, varicocele, or testosterone use
🔬 The first appointment: what to expect
An initial fertility evaluation typically includes: For her: blood work (FSH, AMH, estradiol, TSH, prolactin on cycle day 2–4), pelvic ultrasound (antral follicle count), and HSG or SHG to check tubal patency. For him: semen analysis. These basic tests identify most common fertility issues and typically cost $500–1,500 without insurance. Results guide the next step: continued timed intercourse, IUI, IVF, or targeted treatment for a specific diagnosis.
What NOT to Panic About
- 3–6 months without success (under 35): Completely normal. A 25% monthly chance means 25% of couples take 6+ months.
- One miscarriage: 15–25% of recognized pregnancies miscarry. It's devastating but doesn't usually indicate a problem.
- Irregular first few cycles off birth control: It can take 1–3 months for ovulation to normalize after stopping hormonal contraception.
- “Everyone else got pregnant immediately”: Selection bias. People announce pregnancies; they don't announce months of trying. The average time to conception is 4–6 months for couples under 30.
