We conceived easily before — why secondary infertility now?
Our daughter is 4. We have been trying for 16 months for a second child. I am 33. Why is it harder and what should we test?
Short answer: Secondary infertility is common. Age-related egg quality changes, new male factor, thyroid issues, pelvic infection sequelae or irregular ovulation can appear after a prior birth. Evaluation is similar to primary infertility and should not be delayed by 'you already have one child' advice.
Answer #1
Prior success does not freeze time
Four years later both partners are older, and semen or ovulatory patterns may have changed. Delivery complications, new fibroids, weight changes or quiet endometriosis can also matter. Social pressure to 'keep trying naturally' often delays useful testing.

Answer #2
Start a standard workup
After 12 months under 35 (sooner if cycles are irregular), arrange semen analysis, ovulation assessment, and tubal/uterine evaluation as indicated. Treatment ranges from timed intercourse support to IUI or IVF based on findings—not on the fact that you already parented successfully.

Get matched to one ART-registered clinic after consent — not a directory of calls.
