If you’re under 35 and have been trying to conceive for 12 months without success, it’s time to see a specialist. If you’re 35 to 40, that window shrinks to six months. And if you’re over 40, the recommendation is to seek an evaluation right away, before you start trying. Those are the standard timelines, but several other factors can move up your timeline regardless of age.
About 8.5% of married women of reproductive age in the U.S. are infertile, and roughly 16% have some degree of impaired fertility. These numbers mean fertility struggles are common, and the diagnostic tools available today can often pinpoint the cause quickly for both partners.
Age-Based Timelines for Getting Help
Age is the single biggest factor in how long you should try before scheduling an evaluation. Egg quality and quantity decline steadily over time, and the pace of that decline accelerates in the mid-30s. A blood test that measures a hormone linked to egg supply shows the shift clearly: at age 25, the median level sits around 3.3, but by 35 it drops to 1.4, and by 40 it’s down to 0.5. By age 35, nearly half of women already show markers of diminished ovarian reserve. By 40, that figure rises to 73%.
This is why the timelines tighten with age. Waiting a full year at 38 means losing ground during a period when fertility is declining month to month. If you’re over 40, a proactive evaluation lets you and your doctor understand your starting point and decide whether treatments like egg freezing or assisted reproduction make sense before more time passes.
Signs You Should Seek Help Sooner
The 6- or 12-month guidelines assume everything else about your health is typical. Several red flags justify calling a specialist right away, even if you’ve only been trying for a few months.
Irregular or Missing Periods
If you regularly go more than 35 days between periods, or you’re only getting six to eight periods a year, that’s a sign you may not be ovulating consistently. Without regular ovulation, conception becomes a matter of luck rather than timing. Irregular cycles can point to conditions like polycystic ovary syndrome, which is one of the most common treatable causes of infertility. Don’t wait out the standard timeline if your cycles are unpredictable.
A History of Pelvic Infections or STIs
Pelvic inflammatory disease, often caused by untreated chlamydia or gonorrhea, can scar the fallopian tubes and block the path between egg and sperm. Studies show that about 1 in 8 people who’ve had PID have difficulty getting pregnant, and up to 1 in 10 are eventually diagnosed as infertile. Repeat infections increase that risk further. If you have a history of pelvic infections, bringing it up early gives your doctor a reason to check for tubal damage before you spend months trying.
Two or More Pregnancy Losses
A single miscarriage is unfortunately common and usually doesn’t signal an underlying problem. But two or more consecutive losses meets the U.S. definition of recurrent pregnancy loss and warrants a full evaluation. Testing can look for chromosomal issues, uterine abnormalities, hormonal imbalances, and clotting disorders that may be causing the losses. Genetic testing of the miscarriage tissue itself is typically offered starting with the second loss.
When Men Should Be Evaluated
Fertility is not just a female health issue. A male factor contributes to roughly half of all infertility cases, which is why specialists recommend a semen analysis at the very start of any fertility workup. It’s one of the simplest and least invasive tests in the process.
Beyond the standard timeline of trying for a year, men should seek evaluation sooner if they notice difficulty with erections or ejaculation, reduced sex drive, pain or swelling in the testicle area, or a noticeable lump. Less obvious signs include unusual breast tissue growth, a significant decrease in facial or body hair, or recurring respiratory infections (which can signal a rare genetic condition that also affects fertility). A history of groin, testicle, or scrotal surgery is also worth mentioning early. And if your partner is over 35, that alone is reason to get tested sooner rather than later.
What Happens at an Initial Fertility Evaluation
Knowing what to expect can make the first appointment less intimidating. A thorough evaluation covers both partners and typically unfolds over a few visits rather than a single marathon session.
For the female partner, the workup focuses on three main questions: Are you ovulating? Are your fallopian tubes open? Is the uterus structurally normal? Your doctor will start with a detailed medical and reproductive history, then order blood tests to check ovarian reserve and hormone levels. An ultrasound can count the small follicles in your ovaries and look for uterine abnormalities like fibroids or polyps. A separate imaging test uses dye or saline to check whether the fallopian tubes are open. If your cycles are irregular, additional hormone tests can help identify whether a thyroid disorder, elevated prolactin, or another hormonal issue is disrupting ovulation.
For the male partner, the evaluation starts with a reproductive and medical history and at least one semen analysis, which measures sperm count, movement, and shape. A normal sample contains at least 15 million sperm per milliliter. If results are abnormal, further testing can look for hormonal causes or structural problems.
The entire initial workup often takes two to four weeks, depending on where you are in your cycle when testing begins. Some results come back in days, while others need to be timed to specific points in your menstrual cycle.
OB-GYN vs. Reproductive Endocrinologist
Your regular OB-GYN can order preliminary tests like blood work and a semen analysis, and many handle initial evaluations for straightforward cases. But a reproductive endocrinologist is a subspecialist with additional training in diagnosing and treating infertility, including procedures your OB-GYN’s office isn’t equipped for.
If your initial workup reveals a clear issue, like blocked tubes, low ovarian reserve, a very low sperm count, or recurrent pregnancy loss, a reproductive endocrinologist is the right next step. Fertility treatment with a specialist can be intensive. Depending on the approach, you may have blood draws every two to three days, near-daily office visits during certain phases of treatment, and weekly ultrasounds once a pregnancy is established. Your OB-GYN and reproductive endocrinologist serve different roles: the specialist gets you pregnant, and your OB-GYN takes over once the pregnancy is stable, typically after the first several weeks.
If you’ve been on the fence about whether it’s “too early” to ask for help, consider that an evaluation is just information. It doesn’t commit you to any treatment. Many people leave their first appointment with reassurance and a simple plan, while others discover an issue that would have gone undetected for months. Either way, you’re better off knowing.
