How to Treat Male Infertility

Medically Reviewed By Dr Pamela Frank, BSc (Hons), ND

Male fertility requires these main elements to be at least adequate, but for the best chance at conception and the healthiest baby, we prefer to aim for optimal levels:

  1. Semen volume – the amount of semen per ejaculate
  2. Sperm count – this one is pretty basic, if there is a very low sperm count, the numbers just aren’t high enough to achieve conception
  3. Sperm motility – this is how well do they swim and do they swim determinedly, in a straightforward direction
  4. Sperm morphology – this is the appearance of the sperm, the shape of the head, length of the tail etc.
  5. The DNA of the sperm – the genetic material contained in the sperm determines half of the DNA that will contribute to the future baby.  The health of the DNA is determined through testing for DNA fragmentation.  High DNA fragmentation is closely correlated to increased rates of miscarriage in IUI and IVF.

Normal Ranges for Semen Parameters (Source: World Health Organization, normal and more ideally [25-95th percentile values])

  1. Semen volume = >=1.5 ml [2.7-6.8 ml] per ejaculate
  2. Sperm count = >=15 million/ml of semen [41-213 million]
  3. Sperm motility = >=40% [53-78%], progressive motility – >=32% [47-72%]
  4. Normal forms (morphology) = >= 4% [9-48%]
  5. DNA fragmentation = ≤ 15% DFI = excellent to good sperm DNA integrity, > 15 to < 25% DFI = good to fair sperm DNA integrity, > 25 to < 50% DFI = fair to poor sperm DNA integrity, ≥ 50% DFI = very poor sperm DNA integrity

What Causes Male Infertility?

Factors that Impact Semen Parameters and Sperm Quality

  1. Semen volume – dehydration, retrograde ejaculation (ejaculate flows back into the bladder instead of out the urethra), lack of orgasm (SSRI’s, psychological, nerve injury), duct obstruction, the absence of the vas deferens, hypogonadism (low testosterone or DHT).
  2. Sperm count – the causes of low sperm count include: varicocele, infection, retrograde ejaculation, anti-sperm antibodies, tumors, undescended testicles, hormone imbalance, sperm duct defects, celiac disease, testosterone replacement therapy, long-term anabolic steroid use, cancer medications (chemotherapy), certain anti-fungal and antibiotic medications, some ulcer medications, chemical exposure (like octinoxate, oxybenzone, BPA and PFC), overheating the testicles (sauna, hot tub, tight underwear, laptop use), prolonged cycling, x-rays, heavy metals, smoking, alcohol or drug abuse, soy intake, stress and obesity.
  3. Sperm motility – poor sperm motility can be caused by heat, smoking, alcohol, age, oxidative stress, vitamin and mineral deficiency
  4. Sperm morphology – low sperm morphology may be caused by heat, oxidative stress, age, alcohol intake, vitamin and mineral deficiency
  5. DNA fragmentation – high DNA fragmentation may be the result of heat, coffee consumption, obesity, hormone imbalance, infection, febrile illness, diet, drug use, cigarette smoking, exposure to environmental and occupational pollutants, advanced age and varicocele.

Through scientifically proven nutritional, herbal, dietary and lifestyle options such as those listed below in the research, we can address these causes of infertility in men and fix male fertility.
