Fertility testing typically involves a combination of blood work, imaging, and physical analysis for one or both partners. The specific tests depend on age, how long you’ve been trying, and any known risk factors. Most couples can expect a clear picture of what’s happening within one to two menstrual cycles of starting the evaluation.
The American Society for Reproductive Medicine recommends starting an evaluation after 12 months of regular, unprotected intercourse if the female partner is under 35, or after 6 months if she’s 35 or older. If either partner has a known condition that could affect reproduction, testing can begin sooner.
Blood Tests for Ovarian Reserve
One of the first tests for women is a blood draw measuring anti-Mullerian hormone, or AMH. This hormone reflects the number of eggs remaining in the ovaries, giving a snapshot of your reproductive timeline. It can be drawn on any day of your cycle, which makes it one of the most convenient early tests.
AMH levels naturally decline with age. At 25, a typical level sits around 3.0 ng/mL. By 35 it drops to roughly 1.5 ng/mL, and by 40 it’s closer to 1.0 ng/mL. A result significantly below the expected range for your age suggests a lower egg supply, which matters most for decisions about timing or egg freezing. A normal or high AMH doesn’t guarantee egg quality, though. It’s a quantity marker, not a quality one.
Two other hormones are usually drawn on day 2 or 3 of your period: follicle-stimulating hormone (FSH) and estradiol. FSH is the signal your brain sends to your ovaries to develop an egg each month. When the ovaries have fewer eggs to respond with, FSH rises, so a high level early in the cycle can indicate diminished reserve. Estradiol is checked alongside FSH because an elevated estradiol can artificially suppress FSH, masking a problem.
Confirming Ovulation
Knowing you have eggs is one thing. Confirming you’re actually releasing one each month is another. The standard method is a progesterone blood test, drawn about seven days before your expected period. For a textbook 28-day cycle, that’s day 21. If your cycles are longer or shorter, the timing shifts accordingly. After ovulation, the ovary produces progesterone to prepare the uterine lining for a potential pregnancy. A low level suggests ovulation didn’t occur or was incomplete.
Your doctor may also use transvaginal ultrasound to track follicle development in real time. This involves a series of scans over several days mid-cycle, watching a follicle grow and then confirming it released an egg. Ultrasound monitoring also reveals your antral follicle count, the number of small, developing follicles visible at the start of a cycle. Like AMH, this count helps estimate ovarian reserve.
Checking the Fallopian Tubes and Uterus
Even with healthy eggs and regular ovulation, a blockage in the fallopian tubes or a structural problem in the uterus can prevent pregnancy. The most common test for this is a hysterosalpingogram, or HSG. During the procedure, a thin catheter is inserted through the cervix and a contrast dye is pushed into the uterus while X-ray images are taken. If the tubes are open, the dye spills out the ends. If it stops, that indicates a blockage.
HSG can be uncomfortable. Many women describe it as strong cramping that lasts a few minutes. It also involves a small amount of radiation exposure and isn’t great at detecting problems with the ovaries or the muscle layer of the uterus.
A newer alternative uses ultrasound instead of X-ray. In this version, a foam or saline-and-air mixture is pushed through the tubes while a doctor watches on an ultrasound screen in real time. This approach is less painful than traditional HSG, can be done in a regular exam room with just an ultrasound machine, and is better at detecting abnormalities inside the uterine cavity. Both methods are reliable for identifying tubal blockages, but the ultrasound-based option tends to be more comfortable and more affordable.
Semen Analysis
Male factors contribute to about half of all infertility cases, so semen analysis is one of the earliest tests ordered. You provide a sample, usually after two to five days of abstinence, either at the clinic or at home with a short transport window.
In an andrology lab, the sample is evaluated under a microscope and by computer. The analysis measures several things: total sperm count, concentration (how many sperm per milliliter), motility (the percentage that are actually swimming), and morphology (the percentage with a normal shape). Vitality, the proportion of living sperm, is also assessed. A man can have a high sperm count but poor fertility if most of those sperm aren’t moving or are abnormally shaped.
If the semen analysis comes back abnormal, it’s usually repeated a few weeks later to confirm. Sperm production takes about 72 days, so a single bad result can reflect a temporary issue like illness, heat exposure, or stress.
Hormone Testing for Men
When semen analysis reveals a problem, blood work helps identify the cause. The most common test is total testosterone, which measures both the testosterone circulating freely in the blood and the portion bound to proteins. Low testosterone can impair sperm production directly.
Doctors may also check FSH and LH. In men, FSH drives sperm production in the testes, while LH signals testosterone production. High FSH with low sperm count suggests the testes themselves aren’t responding well. Low FSH and LH point to a signaling problem from the brain. Prolactin, a hormone that’s normally low in men, is sometimes tested too, because elevated levels can suppress testosterone and interfere with fertility.
At-Home Fertility Kits and Their Limits
Consumer fertility kits have become widely available for both men and women. For women, most at-home kits test AMH or FSH from a finger-prick blood sample. For men, smartphone-based sperm tests can estimate total count. These kits aren’t inaccurate for what they measure, but what they measure is limited.
An at-home sperm test might tell you your count looks normal, but it can’t assess motility or morphology. You could have 100 million sperm in a sample, but if none of them are moving, fertility is still compromised. Only laboratory testing provides that full picture. Similarly, a finger-prick AMH test gives you a single number without the ultrasound monitoring, FSH context, or clinical interpretation that makes the result meaningful.
These kits work best as a first look, something that might prompt you to seek a full evaluation sooner rather than later. They don’t replace the multi-layered assessment a fertility specialist provides, and a reassuring result from a home kit shouldn’t delay clinical testing if you’ve been trying without success.
What a Typical Evaluation Timeline Looks Like
For most couples, the initial workup takes one to two menstrual cycles. Blood work for AMH, FSH, and estradiol can be drawn at the first visit if the timing is right. A progesterone check happens later that same cycle. Semen analysis can be scheduled almost immediately. The tubal and uterine evaluation is usually booked for the first half of the following cycle, after your period ends but before ovulation.
By the end of this process, your doctor has a working picture of egg supply, ovulation function, tubal patency, uterine structure, and sperm quality. In roughly 25% of cases, no clear cause is found, a diagnosis called unexplained infertility. That doesn’t mean nothing is wrong. It means the standard tests didn’t catch it, and treatment options still exist. For the remaining 75%, the results point toward a specific factor, whether it’s ovulatory, structural, sperm-related, or a combination, and that guides what happens next.
