Unexplained Infertility: What to Do When All Tests Are Normal

You've done everything right—got the tests, followed the timelines, taken the medications. And yet, there’s still no pregnancy. If this sounds familiar, you may be dealing with unexplained infertility—a frustrating diagnosis that affects up to 1 in 5 couples trying to conceive.

At Sangolkar Hospital, Sangli, we often meet couples who come to us feeling confused and emotionally exhausted after being told “everything looks normal.” This blog breaks down what unexplained infertility really is, what could be going on behind the scenes, and most importantly—what can be done.

❓ What Is Unexplained Infertility?

Unexplained infertility is a diagnosis given when all standard fertility tests return normal results, including:

• Ovulation monitoring

• Semen analysis

• Fallopian tube patency (HSG or laparoscopy)

• Hormonal and ovarian reserve testing
  

Yet, conception still doesn’t happen—naturally or sometimes even with IUI.

This doesn’t mean nothing is wrong. It simply means that the exact cause hasn’t been identified yet with current medical tools.

📊 How Common Is It?

• Affects 15–30% of couples struggling with infertility

• More common in couples under 35

• Often diagnosed after 1–2 years of trying without success despite normal investigations

Unexplained infertility can be deeply distressing because it provides no clear answer, no clear path. But there is hope—many couples go on to conceive with focused treatment and lifestyle support.

🔍 What Could Be Happening Behind the Scenes?

There are several non-detectable or subclinical factors that could be silently affecting your chances of conception:

✔️ Egg and Sperm Timing Mismatch

Even with ovulation, egg quality may be suboptimal or sperm may reach too late.

✔️ Mild Endometriosis

Sometimes too subtle to be seen in scans, it can cause inflammation and interfere with implantation.

✔️ Immunological Factors

Rare cases where the body’s immune system rejects the embryo or sperm as foreign.

✔️ Luteal Phase Defect

Shortened phase after ovulation where progesterone support may be insufficient.

✔️ Sperm DNA Fragmentation

Not always detected in routine semen analysis but can impair fertilization or embryo development.

🧘‍♀️ Best Treatment Options for Unexplained Infertility

1️⃣ Lifestyle Optimization

Start with the basics that matter most:

• Healthy weight (BMI 20–25)

• Stress reduction through mindfulness and yoga

• Balanced fertility diet rich in antioxidants, folic acid, and omega-3

• Limit alcohol, caffeine, smoking
  

🎯 Couples who incorporate these changes have a higher natural conception rate within 6 months.

2️⃣ Timed Intercourse & Ovulation Tracking

Using ultrasound monitoring or LH kits to time intercourse can increase chances by ensuring precise fertilization windows.

3️⃣ Mild Ovarian Stimulation with IUI

For couples who haven’t conceived naturally, low-dose hormonal stimulation + Intrauterine Insemination (IUI) is often the first treatment of choice for unexplained infertility.

🔹 This increases the number of eggs available and bypasses cervical barriers.  🔹 Most effective in women under 35 with regular cycles.

4️⃣ Advanced Testing Options (for resistant cases)

If conception still doesn’t occur, consider:

• Endometrial Receptivity Assay (ERA) to find the best implantation window

• Sperm DNA fragmentation index (DFI)

• Laparoscopy to rule out hidden endometriosis

5️⃣ Fertility Acupuncture

Used alongside conventional treatments to:

• Improve blood flow to reproductive organs

• Regulate hormones and stress

• Enhance embryo implantation rates during IVF/IUI

A 30-year-old couple from Sangli had been trying for 3 years. All reports were normal. We advised:

• 3 months of lifestyle optimization

They conceived in the second IUI cycle. Sometimes, it’s the smallest shifts that make the biggest difference.
