Step 1: Taking a Detailed History
The first step in any infertility evaluation is a long conversation. History is not just a formality—it often provides the first clues.
What we ask the woman about:
- Age and how long she has been trying to conceive.
- Menstrual history: Are cycles regular, painful, or heavy? Do they come every month or are they unpredictable?
- Past pregnancies, miscarriages, or ectopic pregnancies.
- Past medical conditions like thyroid disease, diabetes, or tuberculosis.
- Lifestyle factors such as smoking, alcohol use, weight changes, exercise, and stress.
What we ask the man about:
- Past fatherhood or pregnancies with previous partners.
- Medical history including childhood illnesses like mumps, which can affect the testes.
- Lifestyle factors—smoking, alcohol, drugs, heat exposure from saunas or laptops.
- Sexual history: frequency of intercourse, difficulties with erections or ejaculation.
Why this matters:
Many causes of infertility can be suspected from history alone. For example, irregular cycles suggest ovulation problems. Painful heavy periods could point to endometriosis. Past pelvic infections can damage fallopian tubes. In men, lifestyle habits or erectile issues can directly impair fertility.
Step 2: Physical Examination
Both partners undergo a basic physical exam.
For women: We check height, weight, body mass index, signs of hormonal imbalance (excess hair growth, acne), thyroid swelling, and pelvic examination to feel the uterus and ovaries.
For men: We assess testicular size, the presence of varicocele (enlarged veins around the testes), and secondary sexual characteristics. A properly done semen analysis also gives us clues about these problems
Why this matters:
A simple observation—such as obesity, thyroid swelling, or undescended testes, can provide major clues before even ordering tests.
Step 3: Basic Tests for the Couple
The cornerstone of infertility evaluation is to assess three things: eggs, sperm, and tubes. If eggs are being released, sperm are healthy, and tubes are open, pregnancy usually happens unless there are more subtle issues.
For the woman:
Ovulation assessment: Tracking cycles or using ultrasound to confirm egg release.
- Blood test for progesterone about a week before the expected period or a scan to verify ovulation
- Rationale: Regular ovulation is essential. Without an egg, pregnancy cannot occur.
Hormonal evaluation:
- Thyroid function, prolactin, and sometimes AMH (Anti-Müllerian Hormone) to check ovarian reserve.
- Rationale: Hormonal disorders can prevent ovulation or shorten fertility window.
Pelvic ultrasound:
- To look at the uterus (fibroids, polyps) and ovaries (cysts, polycystic ovaries).
- Rationale: Structural issues may block conception or cause miscarriages.
Tubal testing:
- HSG (hysterosalpingogram), SSG (saline sonography), or laparoscopy to check if fallopian tubes are open.
- Rationale: Blocked tubes are a major cause of infertility, especially in countries where infections are common.
For the man:
Semen analysis:
- At least two samples, checked for sperm count, motility, and shape. Computerised automated analysis is preferred to avoid observer bias
- Rationale: Male factors account for nearly 40% of infertility.
Hormonal profile if needed:
- Testosterone, FSH, LH when sperm counts are extremely low.
Scrotal ultrasound if needed:
- To detect varicocele or structural abnormalities.
Step 4: Additional Tests When Needed
Not every couple needs advanced testing at the beginning. But if basic tests look normal, or if prior treatments have failed, we expand the evaluation.
- Hysteroscopy: To look directly inside the uterus for polyps, adhesions, or abnormal lining.
- Laparoscopy: To look inside the abdomen for endometriosis, pelvic adhesions, or tubal disease.
- Genetic testing: In couples with recurrent miscarriages or very low sperm counts.
- Immunological or advanced hormonal tests: Only when standard pathways do not explain the problem.
Rationale: We escalate investigations only when necessary, to balance thoroughness with cost and comfort.
How Evaluation Differs by Couple Type
1. Young Couples (Woman < 35 years)
- Timeline: We wait at least 12 months before full evaluation unless there are clear red flags like irregular periods, pelvic surgery, or testicular issues.
- Approach: Start with simple tests (ovulation check, semen analysis, ultrasound). If results are normal, we may advise lifestyle modification and timed intercourse for a few more months before moving to treatments.
- Rationale: Most young couples conceive naturally if given time and basic guidance. We try not to overmedicalize too early.
2. Older Couples (Woman ? 35 years)
- Timeline: We shorten the waiting period to 6 months.
- Approach: Comprehensive testing is initiated immediately which include ovarian reserve (AMH, antral follicle count), semen analysis, tubal testing.
- Rationale: Fertility declines sharply after 35. Time is critical, and delay can reduce the chance of successful conception.
3. Couples Who Have Never Tried Fertility Treatments
- Approach: Stick to the standard sequence with basic evaluation first and advanced evaluation only if required or indicated.
- Rationale: Many will respond to simple strategies like ovulation induction or correcting lifestyle issues, without needing IVF or advanced procedures.
4. Couples Who Have Already Had Unsuccessful Treatments
- Approach: Deeper dive is necessary. We ask: why did treatments fail?
- If IUI cycles failed, was the sperm quality marginal? Were the tubes healthy?
- If IVF failed, was fertilization poor? Were embryos abnormal? Was the uterus unfavorable?
- Investigations may include: genetic testing, advanced sperm function tests, endometrial receptivity assessment, or laparoscopy for missed endometriosis.
- Rationale: Repeating the same treatment without identifying the cause of past failure wastes time, money, and emotional energy.
Step 5: Explaining the Findings to the Couple
- A key part of the evaluation is sitting down with the couple to explain results in plain language. We group findings into categories:
- Ovulation issues (e.g., PCOS, thyroid disease).
- Tubal issues (blocked tubes, scarring).
- Uterine issues (fibroids, adhesions, poor lining).
- Male factor (low sperm count, poor motility).
- Unexplained infertility (when everything looks normal but pregnancy does not occur).
- Rationale: Couples need to know not only what is wrong but also what is normal. This reassurance builds confidence and trust.
Step 6: Tailoring the Next Steps
- Once evaluation is complete, we move toward treatment planning.
- Simple problems like irregular ovulation may only need tablets to induce ovulation.
- Male factor issues may need IUI or IVF with ICSI (injecting sperm into the egg).
- Tubal block usually requires IVF.
- Unexplained infertility often responds to a stepwise approach: ovulation induction, then IUI, and finally IVF if needed.
- Rationale: The goal is to match the treatment to the problem, avoiding overtreatment but also not wasting time on ineffective strategies.
Emotional and Practical Aspects
Infertility evaluation is not just about tests and scans. It’s also about the couple’s mental and emotional well-being. Many feel anxious or guilty. The process may strain relationships. We encourage couples to attend consultations together, because infertility is always a shared issue, never the fault of one partner.
Putting It All Together:
- History – understand the couple’s journey, lifestyle, and medical background.
- Examination – simple observations that reveal hormonal or structural issues.
- Basic tests – semen analysis, ovulation check, ultrasound, tubal testing.
- Advanced tests if needed – hysteroscopy, laparoscopy, genetics, endometrial evaluation.
- Interpret results together – classify into ovulation, tubal, uterine, male factor, or unexplained.
- Plan tailored treatment – from lifestyle advice and timed intercourse to IUI or IVF.
