Trying to Conceive: When to See Your OB/GYN and When You Need a Fertility Specialist

Most people who are trying to conceive can start with their own OB/GYN, and only some need a fertility specialist, called a reproductive endocrinologist. A general guide is to seek an evaluation after about 12 months of trying if you are under 35, about 6 months if you are 35 to 39, and right away at 40 and older, or sooner if you have known issues like irregular periods. At Legacy OB/GYN in Frisco, TX, we can start the workup and refer when it makes sense.

If you are trying to conceive, you can almost always start with your own OB/GYN. A fertility specialist is the right step for some people, but for most it is not the first step. The usual path is simpler than it sounds: you begin with the doctor you already see, they look at the basics, and they refer you only if the picture calls for it.

It also helps to know that trying takes time. According to ASRM, most couples with normal fertility, about 85%, conceive within a year of trying, and many within the first six months. So a few months without a positive test is common, and usually not a sign that something is wrong.

At Legacy OB/GYN in Frisco, TX, we treat this as a partnership. We look at where you are, we handle the first steps ourselves when that fits, and we bring in a specialist when it will genuinely help. Here is when to start looking, what your OB/GYN can do first, and when a specialist makes sense.

How long conception usually takes

Conceiving is usually a matter of months, not one perfect try. In any given cycle a healthy couple has a modest chance of conceiving, and those chances add up over time, so most people who keep trying will be pregnant within a year. That is why the standard advice is to give it some time before starting a formal workup, as long as you do not have a known reason to look sooner.

A couple of simple things make the timing easier. Knowing your fertile window, the few days around ovulation, helps you focus your efforts, and basic tracking can tell you whether you are ovulating at all. Our guide to ovulation tracking and your fertile window walks through how to do this without turning it into a second job. You do not need to monitor every detail. A general sense of your cycle is usually enough, and for most couples, having sex every couple of days through the fertile window is plenty without turning it into a chore.

If your cycles are irregular or absent, mention that early, because it can mean you are not ovulating predictably. Irregular cycles are one of the most common reasons couples have trouble, and they are often treatable. PMOS, the condition formerly called PCOS, is a frequent cause, and something we can evaluate for.

When to start a workup by age

The answer comes down to your age and whether you have any known issues. Age matters because fertility and egg quality decline gradually over time, so the point where waiting stops helping and evaluation starts helping shifts earlier as you get older. The thresholds below are a guide, not a hard deadline.

Some situations are worth checking sooner, at any age. Talk with us earlier if any of these apply to you:

• Irregular or absent periods, or known PMOS
• A prior pelvic infection, or prior pelvic or abdominal surgery
• Known or suspected endometriosis
• A known male-factor issue with your partner
• Two or more pregnancy losses

If you are unsure where you land, a short conversation can sort it out. There is no penalty for asking early, and there is real value in not waiting too long when the timing points toward a workup.

What your OB/GYN can do first

Your OB/GYN can handle the first round of a fertility workup, and for many people that first round is all it takes. The early steps are straightforward, and they are usually where answers start to appear:

1. Take a full history for both of you, including your cycles, any past pregnancies, surgeries, medications, and general health.
2. Review whether and when you are ovulating, using your cycle pattern and simple testing.
3. Run basic labs, including hormone levels and a thyroid check, since thyroid problems can affect both cycles and conception.
4. Arrange a semen analysis for your partner. This is a simple but important early test, because male-factor issues are common and easy to overlook if no one checks.
5. Order a pelvic ultrasound when it will add useful information about your uterus and ovaries.
6. Order an HSG when it fits. A hysterosalpingogram is an X-ray test that checks whether your fallopian tubes are open, and it is a standard part of a first-round workup for many patients.
7. Offer first-line ovulation support. We provide in-office ovulation induction, including letrozole, when it is appropriate for your situation, so this step does not require a referral elsewhere.

Much of this overlaps with preconception planning, so if you are earlier in the process, procreative counseling is a good place to start. You can also read more about our approach to a fertility and infertility workup.

When you need a fertility specialist

A reproductive endocrinologist makes sense when the situation calls for testing or treatment beyond what a general OB/GYN office provides. Common reasons to refer include:

• A need for treatments like IUI (intrauterine insemination) or IVF (in vitro fertilization)
• Blocked or damaged fallopian tubes
• Severe male-factor infertility
• Recurrent pregnancy loss, generally two or more losses
• Signs of diminished ovarian reserve, meaning fewer eggs available than expected for your age
• No pregnancy after the first-line steps your OB/GYN has already tried

Think of the specialist as an added set of tools for a specific job, brought in at the right time. When a referral is the right move, your OB/GYN can make it and share your records, so you are not starting the workup over from scratch. The goal is the same as it was on day one, and the path there simply has one more partner on it.
