Male Partner Fertility: Sperm Analysis and Improvement

Male factor accompanies 30-40% of infertility cases, and 20% are caused by men alone. Sperm evaluation is the first step of infertility workup — cheap, easy, and the result provides important direction. This guide covers preconception male preparation.

Spermiogram (semen analysis) requirement: First test of fertility evaluation. WHO 2010/2021 reference values:

• Volume: ≥1.4 ml
• Concentration: ≥16 million/ml
• Total sperm: ≥39 million
• Motility: ≥30% progressive (forward-moving)
• Morphology (shape): ≥4% normal (Kruger criterion)
• pH: ≥7.2
• Leukocytes: <1 million/ml

Test preparation: 2-7 days sexual abstinence (less/more is misleading), no fever or intense stress 3-5 days before test, hot bath/sauna stopped 1 week before, no alcohol 3-7 days before. If result abnormal, repeat at 2-3 month intervals — sperm production cycle is 72-90 days.

Abnormal result types:

• Oligospermia: Low concentration
• Asthenospermia: Low motility
• Teratospermia: Abnormal morphology
• Azoospermia: No sperm (obstructive/non-obstructive)
• OAT syndrome: Triple combination — most common abnormal pattern

Evidence-based approaches to improve sperm quality (3-month structured program needed):

• Lifestyle: Quit smoking (smoking increases DNA fragmentation), alcohol <14 units/week, no recreational drugs, adequate sleep 7-9 hours
• Weight: BMI 19-25 target, both obesity and excessive thinness harmful
• Exercise: Regular moderate intensity — extreme endurance (marathon, triathlon) can reduce sperm count
• Heat exposure: Reduce hot bath, sauna, Jacuzzi, laptop on lap — testicular temperature important

Nutrition:

• Mediterranean diet — sperm parameters improved in randomized studies
• Antioxidant rich: berries, dark leafy greens, chocolate, walnuts
• Zinc (oysters, pumpkin seeds) — testosterone supporter
• Selenium (Brazil nuts, fish) — sperm motility
• Folic acid + B12 — DNA integrity
• Lycopene (tomato) — anti-inflammatory

Supplements (moderate-good evidence):

• Co-Q10 (200-400 mg/day): Motility and count improvement shown in randomized studies
• L-carnitine + L-acetyl carnitine (3 g/day): Strong evidence on motility
• Vitamin C + E + Selenium combination: Reduces oxidative stress
• Zinc (25-50 mg/day): In case of deficiency
• Vitamin D: Correct if deficient
• Omega-3 (1-2 g/day): Membrane health

Before starting these supplements, always consult a doctor for dose and duration; in particular, long-term use of high-dose zinc can lead to copper deficiency.

Medical causes to evaluate:

• Varicocele (sperm vessel enlargement) — in 15% of men; in some cases treatment can improve sperm parameters
• Hormonal issue (FSH, LH, testosterone, prolactin test)
• Genetic (Y chromosome microdeletion, karyotype — for severe OAT or azoospermia)
• Infection (semen culture)
• Blockage (ejaculatory duct)

Environmental factors to avoid: Pesticides, heavy metals (lead, mercury), endocrine disrupting chemicals (BPA, phthalates), prolonged laptop heat, tight clothing, prolonged use of heated car seats (raises scrotal temperature). Replace plastic containers with glass, choose organic when possible.

When IVF/IUI needed: ICSI (intracytoplasmic sperm injection) is the solution in serious male factor. TESE (testicular biopsy with sperm) makes pregnancy possible even in azoospermia. Modern reproductive medicine has changed a lot — there's no place for hopelessness.
