Understanding Male Fertility and How to Improve It: When couples face challenges with fertility, it’s often assumed the issue lies with the female partner. In reality, male factor infertility contributes to nearly 50% of cases. At Reproductive America (Reproductiva), we believe fertility is a shared journey, and sperm health is a critical piece of the puzzle. If you’re planning to conceive or considering IVF, here’s what you should know about the key factors that affect sperm health and what you can do to improve it.
What Defines Healthy Sperm?
A standard semen analysis measures several parameters:
- Count: The number of sperm in the sample (normal is 15 million/mL or more)
- Motility: How well the sperm swim (ideally, 40% or more should be motile)
- Morphology: The shape and structure of sperm (at least 4% normal forms)
- Volume & pH: The quality of the ejaculate fluid and its environment
- DNA Fragmentation: A deeper analysis of sperm integrity (offered at RCA for select cases)
Even small deviations in these factors can impact your chances of conception, especially in IUI or IVF cycles.
Common Causes of Poor Sperm Health
Sperm quality can be influenced by a range of lifestyle, environmental, and medical factors, including:
1. Age
While men remain fertile longer than women, sperm quality tends to decline after age 40, particularly in DNA integrity.
2. Lifestyle Habits
- Smoking reduces sperm count and motility
- Excess alcohol affects hormone levels
- Recreational drugs like marijuana or anabolic steroids impair production
- Obesity is linked to lower testosterone and sperm quality
3. Environmental Exposure
- Heat (hot tubs, saunas, laptops on laps)
- Radiation or toxins (pesticides, heavy metals, plastics)
- Excessive cycling or tight underwear may also raise scrotal temperature
4. Medical Conditions
- Varicocele (enlarged veins in the scrotum)
- Hormonal imbalances (low testosterone, high prolactin)
- Chronic illnesses (diabetes, thyroid disorders)
- STIs or past infections affecting the reproductive tract
How to Improve Sperm Health
The good news: many sperm issues are reversible or manageable with the right steps.
✔ Lifestyle Changes
- Stop smoking and limit alcohol
- Exercise regularly (but avoid overtraining)
- Maintain a healthy BMI
- Get 7–8 hours of sleep
✔ Nutrition & Supplements
- Eat an antioxidant-rich diet (fruits, vegetables, nuts, fish)
- Consider supplements like CoQ10, zinc, vitamin D, folic acid, and L-carnitine (always consult a provider first)
✔ Reduce Heat Exposure
- Skip hot tubs and saunas
- Avoid placing laptops on your lap
- Wear breathable, loose-fitting underwear
✔ Manage Stress
Chronic stress impacts hormone levels and sexual health. Try mindfulness, therapy, or physical activity as a release.
✔ Seek a Medical Evaluation
At RCA, we offer male fertility testing and referrals to reproductive urologists when needed. Some cases require treatment of underlying conditions, surgical correction (like for varicocele), or advanced sperm retrieval methods.
Sperm Health in IVF & ICSI
Even when sperm parameters are abnormal, ICSI (Intracytoplasmic Sperm Injection) can allow fertilization using a single healthy sperm. In some cases, we recommend sperm DNA fragmentation testing or specialized processing techniques to optimize outcomes.
