Detailed Parameter-by-Parameter Analysis
1. Physical Parameters
- Volume: 1.4 mL - Right at the WHO lower limit of 1.4 mL. While technically within range, this is at the very boundary. A low ejaculate volume can reduce the total number of sperm delivered and may reflect partial retrograde ejaculation, ductal obstruction, or short abstinence. The 3-day abstinence period (within normal range) does not explain it.
- Appearance/Viscosity/pH: All normal. Positive fructose confirms the seminal vesicles are functioning and the ejaculatory ducts are patent.
2. Sperm Count - Excellent
- Sperm concentration: 134 million/mL - More than 8x the WHO lower limit of 16 million/mL. This is an excellent count.
- Total sperm in ejaculate: 187.6 million - Well above the 39 million minimum. No oligospermia.
3. Motility - Normal
- Total motility: 51% - Above the 42% cutoff. Normal.
- Progressive motility (a+b): 47% - Well above the 30% cutoff. Normal.
- Rapid progressive (category a): 32% - Meets the ≥30% reference. Normal.
- Immotile sperm: 49% - Slightly above the reference of ≤20% in WHO 2021. This is notable - nearly half the sperm are non-motile, which is elevated. However, since total motility still passes the 42% threshold, this is not classified as asthenospermia.
- Motile Progressive Sperm Concentration (MSC): 62.98 Mil/mL - Very good functional pool.
- Sperm Motility Index (SMI): 197 - Falls in the "Good" category (>160). This composite index reflects overall motility quality.
- Functional Sperm Concentration (FSC): 15.8 Mil/mL - This is in the "Good" range (>13 million/mL), indicating a healthy functional sperm pool.
4. Morphology - Normal (and actually quite good)
- Normal forms: 28% - Well above the WHO minimum of 4%. This is a strong result; many men with fertility issues have morphology near the 4% cutoff.
- Total abnormalities: 70% - This sounds alarming but is expected since ~70% abnormal is the flip side of 28-30% normal; most men have 60-80% morphologically abnormal sperm. This is within typical range.
Breakdown of abnormalities:
- Head defects (28%): Pyriform heads (8%), acrosome defects (5%), amorphous heads (6%), round heads (4%) are the main contributors. Pyriform and amorphous heads can affect fertilization capacity.
- Mid-piece defects (23%): Asymmetrical midpiece (6%), thin midpiece (7%), sharply bent midpiece (5%). Mid-piece defects can impair motility energy.
- Tail defects (12%): Irregular tail (7%) is the main finding - can affect progressive movement.
- Cytoplasmic droplets (7%): Residual cytoplasmic droplets suggest some degree of impaired sperm maturation, though mild.
- Immature sperm (2%): Minimal, not clinically significant.
5. Auto-Agglutination: Grade 1
- Grade 1: Isolated (<10 spermatozoa per agglutinate, many free spermatozoa). This is the mildest possible degree of agglutination. At Grade 1, it has no clinical impact on fertility. Higher grades (3-4) would suggest immunological causes.
6. Cellular Elements
- Pus cells (1-2/HPF): Marginally elevated. Normal is <1/HPF by strict criteria. 1-2 cells is borderline and could indicate mild genital tract inflammation. Not diagnostic alone.
- RBCs (1-2/HPF): Trace amount. Not significant on its own but worth noting - persistent blood in semen (hematospermia) should be investigated if recurrent.
- No bacteria, fungi, Trichomonas, or casts - No evidence of infection.
Overall Impression
This is a good semen analysis overall. The key positive findings are:
- Excellent sperm count - 134 million/mL is far above normal
- Normal motility - 51% total, 47% progressive
- Good morphology - 28% normal forms is well above the 4% minimum
- Strong functional indices - SMI of 197 (Good), FSC of 15.8 (Good)
Minor concerns to be aware of:
- Low-borderline volume (1.4 mL) - At the absolute lower limit. A repeat test is advisable to confirm this is not a collection artifact. If consistently low, investigation for retrograde ejaculation or ejaculatory duct issues may be warranted.
- High immotile fraction (49%) - While total motility is technically normal (51%), nearly half the sperm not moving at all is above the WHO reference (≤20% immotile). This is worth monitoring, though not disqualifying with current fertility goals.
- Mid-piece and tail defects - The 23% mid-piece and 12% tail abnormalities can theoretically impair functional motility, though current motility indices compensate well.
- Trace pus cells - Not diagnostic of infection, but if the person is experiencing any urogenital symptoms, a culture may be worthwhile.
Clinical Interpretation
Based on WHO 6th Edition (2021) criteria, this sample does not meet criteria for oligospermia, asthenospermia, or teratospermia. For a couple trying to conceive naturally, this semen profile is generally favorable. The high sperm count and good morphology are particularly reassuring.
Note: Semen analysis is one component of fertility evaluation. A single test has natural variability; if fertility issues persist, a repeat test (ideally 2-3 weeks apart) and clinical consultation with a urologist or reproductive specialist is recommended. This analysis does not constitute medical advice.

Here is a detailed analysis of how vaping specifically impacts each parameter from this report:
How Vaping Affects This Semen Report
E-cigarettes deliver nicotine, heavy metals (cadmium, lead), volatile aldehydes (acrolein, formaldehyde), and flavoring chemicals directly into the bloodstream. The effects on each parameter of this report are mapped below.
Parameter-by-Parameter Impact
Volume: 1.4 mL (already borderline)
Vaping makes this worse.
Nicotine constricts smooth muscle in the seminal vesicles and prostate, which can reduce ejaculate volume. This result is already sitting at the WHO lower limit - vaping could push it below the threshold. Flavoring chemicals in e-liquids have also been shown to have direct glandular toxicity in animal models (PMC10053939).
Sperm Count: 134 million/mL (excellent - currently very safe)
Risk of reduction with continued vaping.
A cross-sectional Danish study found daily e-cigarette users had significantly lower total sperm counts (91 million) vs. non-users (147 million). Nicotine disrupts the hypothalamic-pituitary-gonadal (HPG) axis, reduces testosterone, and directly inhibits spermatogenesis in Sertoli and Leydig cells. The current count of 134 million/mL provides a large buffer, but prolonged vaping could erode this advantage over time.
Motility - Total 51% / Progressive 47% (currently normal)
This is the most vulnerable parameter.
This is where vaping does the most damage, and this report already shows a red flag - 49% immotile sperm (above the WHO upper limit for immotility). Research shows:
- Nicotine impairs mitochondrial function in the sperm mid-piece, directly reducing ATP production needed for flagellar movement
- The World Journal of Men's Health review (2024) confirms nicotine in any form (vaping included) reduces sperm motility
- A 2017 British Fertility Society study found direct exposure to e-liquid flavoring caused a significant decrease in human sperm motility in cultured specimens
With continued vaping, the already-high immotile fraction (49%) is likely to increase, and total motility could drop below the 42% WHO cutoff - turning a normal result into asthenospermia.
Morphology: 28% normal (very good - currently safe)
Moderate risk with continued exposure.
Animal studies show e-cigarette vapor specifically causes teratozoospermia with characteristic tail defects - looped tails, flagellar angulation, and absent flagellum. This report already shows:
- 12% tail abnormalities (irregular tail 7%)
- 23% mid-piece abnormalities
These exact defect types are the ones most strongly linked to e-cigarette vapor exposure. While the 28% normal forms is currently excellent, vaping selectively worsens mid-piece and tail defects - the very abnormalities already present in this report.
Immotile Sperm: 49% (already above normal)
Direct and significant concern.
This is the parameter most immediately impacted by vaping. Normal is ≤20% immotile (WHO 2021). At 49%, this person is already well above that. Nicotine disrupts histone-to-protamine transition and nuclear protein integrity in sperm, which is strongly linked to reduced motility and increased immotility. The WJMH review specifically identifies this mechanism.
DNA Fragmentation (not tested here - but critical)
Vaping almost certainly increases it.
This report did not include a sperm DNA fragmentation index (DFI) test. This is a significant gap. Research consistently shows:
- E-cigarette vapor causes higher DNA damage in both testis and sperm
- Nicotine triggers oxidative stress, which attacks sperm chromatin
- High DNA fragmentation can cause early miscarriage even when all semen analysis parameters appear normal
Recommendation: Get a Sperm DNA Fragmentation (DFI) test done separately.
Auto-Agglutination: Grade 1 (minimal)
Vaping may worsen this indirectly.
Vaping causes low-grade systemic and genital tract inflammation. Inflammation can promote anti-sperm antibody formation, which drives agglutination. The current Grade 1 is not clinically significant, but chronic inflammatory exposure from vaping could progress this over time.
Pus Cells: 1-2/HPF (borderline)
Vaping adds to this risk.
Nicotine and e-cigarette chemicals increase oxidative stress and promote leukocyte infiltration into seminal fluid. The trace pus cells seen here are borderline. Continued vaping increases the chance of genital tract inflammation, which could elevate this to a clinically significant leukocytospermia (>1 million WBC/mL).
Summary Table
| Parameter | Current Status | Vaping Effect | Risk |
|---|---|---|---|
| Volume (1.4 mL) | Borderline | Reduces further | ⚠️ High |
| Sperm Count (134M/mL) | Excellent | Gradual reduction | 🟡 Moderate |
| Total Motility (51%) | Normal | Decreases motility | ⚠️ High |
| Immotile Sperm (49%) | Already elevated | Increases further | 🔴 Immediate |
| Morphology (28%) | Excellent | Tail/midpiece defects worsen | 🟡 Moderate |
| DNA Fragmentation | Not tested | Known to increase | 🔴 Critical gap |
| Auto-Agglutination | Grade 1 | May progress | 🟡 Low-moderate |
| Pus Cells | Borderline | Can worsen | 🟡 Moderate |
Bottom Line
This report currently shows good sperm quality but has two pre-existing vulnerabilities - borderline volume and elevated immotile fraction. Vaping specifically attacks the parameters that are already close to the edge in this report. The mechanism is mainly:
- Nicotine - inhibits spermatogenesis, disrupts HPG axis, impairs mitochondrial motility machinery
- Oxidative stress from aerosols - DNA damage, increased immotility
- Heavy metals and aldehydes - direct testicular toxicity, chromatin damage
- Flavoring chemicals - shown to reduce motility even in direct sperm exposure tests
If fertility is a goal, quitting vaping is one of the highest-yield lifestyle interventions available. Sperm has a ~74-day production cycle, meaning parameters can meaningfully improve within 2-3 months of stopping.
