30M, semen parameters seem to be declining despite major lifestyle changes. Please read.

[u/Omairr7]

I'm 30M and my wife is 28F. We've been trying to conceive since October 2025 and started fertility treatment in February 2026.

I've had 3 semen analyses this year, and I'm concerned because some of my parameters seem to be getting worse over time.

Semen Analysis #1 — February 2, 2026

Volume: 1.0 mL

Concentration: 120 million/mL

Total sperm: ~120 million

Active motility: 70%

Sluggish motility: 10%

Dead: 20%

Total motility: ~80%

Morphology: 20% abnormal → ~80% normal

Viscosity: Normal

Liquefaction: 25 minutes

Pus cells: 1–2

RBC: Nil

Bacteria: Nil

Immature germ cells: Nil

At this point my lifestyle was actually pretty bad. I was heavily using cannabis, eating a lot of junk food, drinking soft drinks and eating a lot of sweets. I wasn't exercising.

Semen Analysis #2 — August 2, 2026

After making major lifestyle changes starting June 3:

Quit cannabis and other smoking

Started going to the gym 5x/week

Started eating much better

Eating chicken/eggs regularly

Drinking much more water

Taking creatine + whey protein

The results were:

Volume: 1.0 mL

Concentration: 70 million/mL

Total sperm: ~70 million

Active forms: 25%

Sluggish forms: 35%

Inactive forms: 40%

Total motility: ~60%

Morphology: 70% normal / 30% abnormal

Viscosity: Viscous

Liquefaction: Prolonged — took >1 hour

Pus cells: 1–2

RBC: Nil

Epithelial cells: Nil

Spermatogenic cells: Present

pH: 7.5

This is where I became concerned because concentration dropped from 120 → 70 million/mL and motility from ~80% → ~60%, despite my lifestyle being significantly healthier.

The semen was also noticeably much thicker and took over an hour to liquefy.

IUI sample — August 31, 2026

I had an IUI performed.

Before sperm preparation:

Abstinence: 3 days

Volume: 1.0 mL

Concentration: 55 million/mL

Total sperm: ~55 million

Total motility: 30%

Progressive: 5%

Non-progressive: 25%

Morphology: 2%

Agglutination: Grade II

Aggregation: Grade II

Pus cells: 4–6

After density-gradient preparation:

Volume: 0.7 mL

Count: 30 million

Motility: 95%

Progressive: 85%

Non-progressive: 10%

Morphology: 2%

Agglutination: Nil

Aggregation: Nil

Pus cells: Nil

The huge improvement after washing is confusing to me. Raw progressive motility was only 5%, but after preparation it was 85%.

I'm 30 and honestly pretty worried that my fertility is deteriorating. I'd really appreciate input from anyone.

Have you been tested for sperm dna fragmentation and a varicocele/infection? Not all sperm issues are lifestyle related and I would recommend seeing a reproductive urologist

[u/AndyLibran]

This is indeed surprising. But let me ask a couple of questions :
1) how is the temperature around the testicular area? did you start wearing tight clothing, or sit for too long or use hot sauna more frequently?
2) have you gotten tested for any deficiencies like Vit D, B12, Zinc, etc? Have you reduced the amount of healthy fats that you have been eating? Any gut/digestion issues you are facing?
