Among couples struggling to conceive, the male factor accounts for roughly 40–50% . The old assumption that “failure to conceive is always the woman’s problem” is a common misconception — modern reproductive medicine emphasizes that both partners should be evaluated together . The good news is that the vast majority of male factors can be effectively addressed through lifestyle changes, medication, or assisted reproductive technology — especially ICSI (intracytoplasmic sperm injection) .

1. Semen Analysis: How to Read the Report

Semen analysis is the most basic test for assessing male fertility. Four parameters matter most:

  • Count (concentration): The normal reference is ≥ 15 million/mL (WHO 5th edition). Low concentration is called oligozoospermia.
  • Motility: Progressive motile sperm (PR) should be ≥ 32% . Poor motility is called asthenozoospermia.
  • Morphology (normal form rate): Under strict criteria, ≥ 4% is considered normal. A high abnormality rate does not mean “cannot conceive” — it lowers the chance of natural pregnancy.
  • Volume and total progressive count: Together these reflect delivery and fertilization capacity.

An abnormal report is no cause for panic — semen parameters fluctuate with fever, stress, and days of abstinence. It is usually recommended to repeat the test twice , 2–4 weeks apart, and take the average.

2. Common Causes of Male Infertility

  • Varicocele: Enlargement of the veins in the scrotum raises local testicular temperature and traps metabolic waste. It is the most common correctable male factor (present in about 40% of infertile men). Microsurgical ligation can improve parameters.
  • Reproductive tract infection: Infections such as chlamydia and mycoplasma can cause epididymitis or obstruction, which are often reversible with timely treatment.
  • Genetic factors: Klinefelter syndrome (47,XXY), Y-chromosome microdeletions, and CFTR gene mutations can cause azoospermia or severe oligozoospermia and require genetic testing to clarify.
  • Endocrine abnormalities: Disruption of the hypothalamic–pituitary–testicular axis (e.g., hyperprolactinemia, hypogonadotropic hypogonadism).
  • Environmental and lifestyle factors: Prolonged sitting, saunas/hot baths, smoking, alcohol abuse, obesity, and long-term exposure to high heat or chemical toxins (pesticides, heavy metals, plasticizers) all damage sperm.
  • Iatrogenic factors: Chemotherapy, radiotherapy, and some medications (such as long-term androgens or certain antihypertensives) can suppress sperm production.

3. How ICSI Solves the Male Factor

ICSI injects a single morphologically normal sperm directly into the egg under a microscope. It breaks through the limitation that “sperm must swim in on their own”:

  • Men with severe oligozoospermia, asthenozoospermia, or teratozoospermia can form embryos as long as a small number of usable sperm can be retrieved.
  • Obstructive azoospermia can be treated with testicular/epididymal sperm aspiration ( TESA/PESA ) combined with ICSI to have one’s own biological child.
  • Some non-obstructive azoospermia cases can find focal sperm production through microdissection testicular sperm extraction ( micro-TESE ).

At FertiJourney’s partner, Luohu Hospital in Shenzhen , ICSI is a routine, mature technique. Combined with the embryologists’ extensive experience, it significantly improves pregnancy chances for couples with a male factor.

4. DNA Fragmentation Index (DFI) Testing

Does the standard semen analysis “look normal” but you still suffer repeated miscarriage or IVF failure? The problem may lie in the sperm DNA fragmentation index (DFI) . Oxidative stress, varicocele, infection, and smoking can damage sperm DNA integrity. A DFI > 30% is generally associated with increased miscarriage risk and reduced implantation rates. Improvements include antioxidant supplements, treating varicocele and infection, avoiding heat and toxins, and, when necessary, ICSI + testicular sperm retrieval (testicular sperm often have lower DFI than ejaculated sperm).

5. Preparing: Male Fertility Optimization

Sperm production takes about 74 days , so optimization needs at least 2–3 months to show effect:

  • Diet: Increase intake of foods rich in antioxidants and zinc, selenium, and vitamins C/E — tomatoes (lycopene), nuts, deep-sea fish, leafy greens, and oysters and other shellfish. Limit processed meat and trans fats.
  • Supplements: Under medical guidance, consider coenzyme Q10, L-carnitine, zinc, selenium, folic acid, vitamin D, and vitamin E , which help improve motility and DNA integrity.
  • Lifestyle: Quit smoking and alcohol; avoid saunas and prolonged sitting; keep a regular sleep schedule; control weight (ideal BMI 18.5–24 ); reduce plasticizer and heat exposure; exercise moderately but avoid long cycling that compresses the perineum.
  • Mental health: Stress raises oxidative stress, so it is equally important for partners to relax together.

6. The Andrology Advantage at Luohu Hospital in Shenzhen

The Reproductive Center of Luohu People’s Hospital has a systematic evaluation and treatment pathway for male factors: from semen analysis, sex hormone and genetic testing, to varicocele surgery, sperm aspiration, and ICSI — backed by an experienced andrology and embryology team. Through FertiJourney, international patients also receive English-language accompaniment, exam coordination, and transparent pricing. A complete cycle costs about $4,500–6,000 , 60–70% lower than in Europe and the US.

If you or your partner have an abnormal semen analysis, you don’t have to face the anxiety alone. Book a free consultation now, and let the FertiJourney medical team design a plan that evaluates both partners and targets the cause. You can also reach us directly on WhatsApp at wa.me/8618886468446.

7. Frequently Asked Questions

Does one abnormal semen analysis mean infertility? Not necessarily. Semen parameters fluctuate greatly with days of abstinence, recent fever, and stress. It is recommended to repeat the test twice, 2–4 weeks apart.

Can a man with azoospermia still have his own child? In most cases, yes. Obstructive azoospermia can be treated with sperm aspiration + ICSI; some non-obstructive cases can also find sperm through micro-TESE. The cause must be assessed by an andrologist.

Do men need to take folic acid? Yes. Folic acid, together with zinc and selenium, participates in sperm DNA synthesis. Both partners supplementing helps reduce the risk of embryonic chromosomal abnormalities.
