From my good friend Claude:
Understanding the Baseline
Sperm morphology is measured by the percentage of "normal forms" (NF). Under the Kruger strict criteria, results under 14% may be considered abnormal, while the WHO's threshold is 4%. Even healthy, fertile men produce a high percentage of abnormal sperm.

Lifestyle Changes
- Exercise — Studies have found that physically active men have improved sperm morphology, while diets high in added sugars, fried foods, and red meats have been linked to lower sperm morphology. Fertility Family
- Quit smoking — A 2019 review found a direct link between poor sperm morphology and smoking. Fertility Family
- Reduce alcohol — A review of 15 studies on alcohol and male fertility found that daily alcohol consumption consistently reduces sperm morphology and semen volume. The good news is these effects appear to be reversible, and men who want to conceive should consider reducing alcohol intake at least three months before trying. CNY Fertility
- Weight management — Some research suggests that increasing BMI is linked with decreasing sperm count and movement. Mayo Clinic
- Stress reduction — Stress raises cortisol levels, which can negatively impact sperm production. Apollo 247
- Reduce heat exposure — Frequent exposure to high temperatures from hot tubs, tight underwear, or laptops can negatively affect sperm morphology. Apollo 247
Nutrition & Supplementation
A combination of antioxidants — particularly vitamin C, vitamin E, and CoQ10 — can effectively improve semen parameters in infertile men. Carnitine also has positive effects on sperm motility and morphology, and simultaneous administration of vitamins E and C reduces sperm DNA damage.

Taking antioxidants in male fertility supplements for three or more months has been shown by some researchers to improve abnormal sperm morphology.
Loma Linda Fertility
Key nutrients to focus on: zinc, selenium, folate, omega-3 fatty acids, vitamin D, CoQ10, and L-carnitine.
Important Timing Note
Sperm take approximately 40–80 days to fully develop, so making positive changes at least 40–90 days before a semen analysis or attempting conception can maximize benefits.

Medical Interventions (if needed)
If lifestyle changes don't improve sperm morphology after 3–6 months, a fertility specialist may recommend hormone therapy (if low testosterone is the cause), antibiotics for infections, varicocele surgery, or assisted reproductive techniques like IVF or ICSI.

The big picture: morphology is just one dimension of male fertility, but it's responsive to lifestyle. A 3-month committed intervention covering diet, supplements, exercise, and eliminating harmful habits tends to show measurable improvement.
