Understanding fertility test results

Before diving into specific tests, some important context:

Results need professional interpretation:

• Numbers alone don't tell the full story
• Your doctor considers all results together
• Age and circumstances affect interpretation
• Same result can mean different things for different people

Normal ranges vary:

• Different labs use different reference ranges
• "Normal" depends on timing in cycle
• What's normal for population may not be optimal for conception
• Some tests have wide normal ranges

One test isn't definitive:

• Hormones fluctuate cycle to cycle
• Abnormal results often need repeating
• Single test doesn't determine your fertility
• Trends over time may matter more

What tests can and can't tell you:

Can tell:

• Whether ovulation is occurring
• Quantity of eggs remaining
• Basic sperm parameters
• Whether tubes are open
• Presence of structural issues

Can't tell:

• Egg quality (no test for this)
• Subtle sperm function issues
• Exactly when you'll conceive
• If a specific pregnancy will succeed

Receiving results:

• Ask for copies of all results
• Request explanation of anything unclear
• Write down or request written summary
• Ask what results mean for YOUR treatment plan

Common hormone tests and what they mean:

AMH (Anti-Müllerian Hormone)

What it measures: Ovarian reserve (egg quantity)

When tested: Any day

Normal range: Varies by age, but typically 7-25 pmol/L or 1-3.5 ng/ml

Interpretation:

• Higher = more eggs
• Lower = fewer eggs
• Doesn't measure quality
• Low AMH doesn't mean you can't conceive
• Very high may indicate PCOS

FSH (Follicle Stimulating Hormone)

What it measures: Ovarian function

When tested: Day 2-3 of cycle

Normal range: Under 10 IU/L

Interpretation:

• Higher FSH may indicate reduced ovarian reserve
• Must interpret with estradiol level
• High early estradiol can falsely suppress FSH

LH (Luteinising Hormone)

What it measures: Ovulation trigger hormone

When tested: Day 2-3, or to detect ovulation surge

Normal range: Similar to FSH in early cycle

Interpretation:

• High LH:FSH ratio may indicate PCOS
• LH surge triggers ovulation
• Tracked by ovulation predictor kits

Progesterone (Day 21 or 7 days before period)

What it measures: Confirms ovulation occurred

When tested: Mid-luteal phase

Normal range: Above 30 nmol/L suggests ovulation

Interpretation:

• Shows ovulation happened
• Low levels may mean anovulation
• Timing is crucial - must be 7 days before period

Thyroid (TSH)

Normal: 0.4-4.0 mIU/L, but ideally under 2.5 for conception

Interpretation:

• High = underactive thyroid (affects ovulation, miscarriage risk)
• Low = overactive thyroid
• Easily treated with medication

Understanding male fertility testing:

Key parameters and WHO reference values:

Volume: Amount of ejaculate

• Normal: 1.5 ml or more
• Low: May indicate blockage or collection issue

Concentration: Sperm per ml

• Normal: 15 million/ml or more
• Low: Oligozoospermia

Total count: Total sperm in sample

• Normal: 39 million or more
• Calculated: concentration x volume

Total motility: Percentage moving

• Normal: 40% or more
• Includes all movement types

Progressive motility: Swimming forward

• Normal: 32% or more
• Most important for reaching egg

Morphology: Normal shaped sperm

• Normal: 4% or more (strict criteria)
• Even fertile men have mostly abnormal shapes
• 4% is actually normal!

Interpreting results:

Mild abnormalities:

• Often fluctuate between tests
• May not significantly impact fertility
• Lifestyle changes may help
• Often proceed with IUI or natural conception

Moderate abnormalities:

• May need IUI or IVF
• Consider specialist urology review
• Lifestyle optimization important

Severe abnormalities (very low count or motility):

• Usually needs ICSI (sperm injection)
• May need further investigation
• Consider underlying causes

Important notes:

• Repeat abnormal tests before concluding
• 3-month lifestyle changes can improve results
• One poor test doesn't define fertility
• Even very low counts can achieve pregnancy with treatment

Understanding imaging test findings:

Ultrasound scan

Antral Follicle Count (AFC):

• Counts small follicles in ovaries
• Normal: 6-10 per ovary
• Low AFC: May indicate reduced reserve
• High AFC: May indicate PCOS
• Correlates with AMH

Ovarian appearance:

• Size and structure
• PCOS appearance (many small follicles)
• Cysts (functional or abnormal)
• Endometriomas (chocolate cysts)

Uterus:

• Size and shape
• Fibroids (location matters more than size)
• Polyps (can be removed)
• Endometrial appearance
• Abnormalities present from birth

Hysterosalpingogram (HSG)

What it shows: Tubes and uterine cavity with dye

Normal finding: Dye flows through both tubes (bilateral spill)

Abnormal findings:

• Blocked tube(s) - no spill seen
• Hydrosalpinx (fluid-filled tube)
• Uterine filling defects (polyps, fibroids)
• Uterine shape abnormalities

Interpretation:

• Blocked tubes mean IVF may be needed
• Some blockages can be repaired
• Uterine issues often correctable

HyCoSy (ultrasound with contrast)

Similar to HSG but using ultrasound

• No radiation
• Shows tube patency
• Can assess uterus at same time

Laparoscopy findings (if done)

• Endometriosis staging (minimal to severe)
• Adhesions (scar tissue)
• Tubal damage assessment
• Ovarian cysts
• Treatment can often happen at same time

What different result patterns might mean:

"All results are normal"

• Good news - no obvious barriers
• May be unexplained infertility
• Egg quality can't be tested
• Treatment options still available
• Prognosis often good

"Your ovarian reserve is low/diminished"

• Fewer eggs remaining than average
• Doesn't measure quality
• May still conceive naturally
• Time may be a more pressing factor
• Earlier treatment often advised
• IVF may be recommended sooner

"You're not ovulating regularly"

• Often very treatable
• Medications can induce ovulation
• Clomid or letrozole commonly used
• Success rates with treatment are good
• Underlying cause (PCOS, thyroid) should be addressed

"Your tubes are blocked"

• Prevents natural conception
• IVF bypasses tubes completely
• Surgery sometimes helpful
• Prognosis with IVF usually good

"Sperm parameters are low"

• Very common finding
• Lifestyle changes may help
• IUI may overcome mild issues
• IVF/ICSI effective for severe issues
• Most can still father children with treatment

"You have endometriosis"

• Affects fertility through multiple mechanisms
• Severity matters
• Surgery sometimes helpful
• Treatment may be recommended
• IVF often effective

Next steps after any result:

• Discuss with your doctor
• Understand treatment options
• Ask about success rates for your situation
• Consider second opinion for complex cases
