Your OB-GYN or primary care doctor is the right starting point when you’re trying to get pregnant. Either one can provide a preconception visit, which covers your health history, medications, and any adjustments needed before conception. From there, you may need additional specialists depending on your age, medical history, and how long you’ve been trying.
Start With Your OB-GYN or Primary Care Doctor
The American College of Obstetricians and Gynecologists recommends that all providers routinely ask patients whether they’d like to become pregnant in the next year. That means your primary care doctor is just as qualified to start this conversation as your OB-GYN. If you already see an OB-GYN regularly, they’re the natural choice. If not, your primary care doctor can handle the initial work and refer you when needed.
A preconception visit is the single most useful appointment you can schedule before you start trying. During this visit, your doctor will review your medical conditions, current medications, and any prior surgeries. They’ll ask about your menstrual cycle regularity, your birth control history, and any previous pregnancies. Some medications, including certain ones for acne, blood pressure, and mood disorders, are unsafe during pregnancy and need to be swapped for alternatives before you conceive. Your doctor will also check that your vaccinations are current, screen for sexually transmitted infections if needed, and recommend starting a prenatal vitamin with folic acid.
This visit is also where your doctor screens for conditions that could complicate pregnancy or make conception harder. Irregular periods, a history of pelvic surgery, or conditions like polycystic ovary syndrome may prompt earlier referrals to a specialist rather than a wait-and-see approach.
When to See a Fertility Specialist
A reproductive endocrinologist is the specialist you’d see if you’re having trouble conceiving. These doctors complete additional fellowship training beyond OB-GYN residency, focusing specifically on hormonal causes of infertility and assisted reproduction techniques like IVF. Your OB-GYN or primary care doctor will typically refer you based on how long you’ve been trying and your age.
The guidelines from the American Society for Reproductive Medicine are straightforward:
- Under 35: Seek evaluation after 12 months of trying without success.
- 35 to 39: Seek evaluation after 6 months.
- 40 and older: More immediate evaluation is warranted, often before or right when you start trying.
A reproductive endocrinologist can run hormone panels, assess ovarian reserve, check for structural issues like blocked fallopian tubes, and coordinate advanced treatments. They also work with genetics teams when there’s a history of recurrent pregnancy loss or known chromosomal concerns. If your situation involves something like absent ovulation, endometriosis, or unexplained infertility, this is the doctor who manages your care from diagnosis through treatment.
The Role of a Urologist for Male Fertility
About half of infertility cases involve a male factor, so your partner’s fertility matters just as much. A semen analysis is usually one of the first tests ordered during an infertility workup, and it can be requested by your OB-GYN or reproductive endocrinologist. If the results come back abnormal, a urologist who specializes in male reproduction takes over.
A semen analysis looks at sperm count, movement, and shape. If the initial results are abnormal, the test is typically repeated after about three months to allow a full cycle of sperm production to complete. Low sperm counts may prompt hormone testing, and very low counts (under 5 million per milliliter) can indicate genetic issues that need further evaluation through chromosomal testing. A urologist also checks for physical causes like blockages in the reproductive tract, which can sometimes result from past infections or anatomical differences. These are treatable problems, but they require a specialist to diagnose.
Genetic Counseling Before Conception
Carrier screening is a blood test that checks whether you carry genes for certain inherited conditions you could pass to a child, even if you’re perfectly healthy yourself. ACOG recommends that screening for cystic fibrosis and spinal muscular atrophy be offered to all women considering pregnancy. Screening for Tay-Sachs disease is recommended for specific populations, including those of Ashkenazi Jewish descent.
Ideally, carrier screening happens before pregnancy so you have the fullest range of options. If you test positive as a carrier, your partner gets tested next. If both of you carry the same condition, a genetic counselor helps you understand the odds and discuss options, which can range from natural conception with prenatal testing to using IVF with embryo screening. Anyone with a family history of a genetic condition should be offered screening for that specific condition. Your OB-GYN can order carrier screening panels, and if results are complex, they’ll refer you to a certified genetic counselor for a deeper conversation.
Specialists for Existing Health Conditions
If you have a chronic condition like diabetes, thyroid disease, or high blood pressure, you’ll want to loop in the specialist who manages that condition before you conceive. Pregnancy changes how your body processes medications and hormones, and some treatments need adjustment weeks or months in advance.
For diabetes, getting blood sugar tightly controlled before conception significantly reduces the risk of complications for both you and the baby. This often means working with an endocrinologist to review and adjust your medications, since some oral diabetes drugs aren’t recommended during pregnancy. Similarly, thyroid hormone levels directly affect fertility and early fetal development, so your levels need to be optimized before conception rather than corrected after the fact. If you take blood pressure medication, certain classes of drugs can cause birth defects and need to be switched to safer alternatives before you start trying.
The common thread is timing. These medication changes work best when they happen before conception, not after a positive pregnancy test. A preconception visit with your primary doctor or OB-GYN is the place to identify which specialists you need to see and in what order.
Maternal-Fetal Medicine Specialists
A maternal-fetal medicine doctor, sometimes called a perinatologist, is a high-risk pregnancy specialist. You generally won’t see one while you’re trying to conceive, but your OB-GYN may recommend a preconception consultation if you have a condition that makes pregnancy particularly risky. This includes things like a history of preterm birth, a heart condition, an autoimmune disease, or a prior pregnancy with serious complications.
This consultation helps you understand what a pregnancy would look like given your specific health picture, what monitoring you’d need, and whether any changes to your care plan should happen before conception. It’s a planning visit, not an ongoing relationship at that stage. Once you’re pregnant, the maternal-fetal medicine specialist may co-manage your care alongside your OB-GYN or simply consult at key points.
Putting the Pieces Together
For most people, the path is simple: schedule a preconception visit with your OB-GYN or primary care doctor, get screened, start prenatal vitamins, and begin trying. If you’re under 35 and healthy, you may not need any other specialists unless something comes up during that first year. If you’re over 35 or have known health concerns, your preconception visit sets the roadmap for which specialists to see and when. The key is not to skip that first appointment. It’s the one visit that catches medication conflicts, missing immunizations, and undiagnosed conditions before they become complications.
