Male Fertility: Beyond the Basics
What Every Man Should Know About His Reproductive Health
When people talk about fertility, the focus often leans heavily toward women, but the truth is, male factors contribute to nearly 50% of infertility cases. While sperm count and motility are often mentioned, the full picture of male fertility goes much deeper. At Reproductive Centers of America (RCA), we believe men deserve the same clarity, support, and care as women when it comes to understanding their reproductive health. Let’s look beyond the basics and unpack the full story of male fertility.
The Core Metrics: Sperm Health 101
Yes, sperm count, motility, and morphology are important—but they’re just part of the story. A deeper understanding includes:
- Volume: Total semen output can reflect glandular function
- Concentration: Number of sperm per milliliter
- Progressive motility: Whether sperm are moving forward efficiently
- Morphology: Percentage of sperm with ideal shape
- DNA fragmentation: Measures genetic integrity, often missed in basic semen analysis
Factors That Influence Male Fertility
Age
Sperm quality gradually declines with age, especially after 40. Increased age is associated with higher DNA fragmentation and greater risk of genetic mutations in offspring.
Diet and Lifestyle
- A diet high in processed foods, sugar, and alcohol can impair hormone production and sperm function
- Nutrient deficiencies (zinc, selenium, omega-3s) affect testosterone and sperm quality
- Exercise, but not excessive training, supports healthy hormone levels
Heat and Toxins
- Hot tubs, saunas, and tight underwear can impair spermatogenesis
- Tobacco, marijuana, heavy alcohol, and environmental toxins (pesticides, phthalates) can decrease sperm count and morphology
Medications and Supplements
- Some prescriptions (testosterone therapy, anabolic steroids, antidepressants) can suppress sperm production
- Over-the-counter supplements marketed for “testosterone” may do more harm than good—always consult your provider
Advanced Testing and Treatment Options
If a basic semen analysis doesn’t explain fertility issues, RCA offers:
- DNA fragmentation testing
- Hormone panels (FSH, LH, prolactin, testosterone, estradiol)
- Scrotal ultrasound to check for varicocele or obstruction
- Genetic testing for Y-chromosome microdeletions or karyotype abnormalities
- Lifestyle and nutritional counseling
- Collaboration with andrologists and urologists for complex cases
Common Myths We Hear
- “If I can ejaculate, I must be fertile.”
➤ Ejaculation doesn’t guarantee sperm health or count. - “I already have a child, so I’m fine.”
➤ Sperm quality can change due to age, illness, or lifestyle. - “Only low testosterone affects fertility.”
➤ Hormone balance is more nuanced—too much testosterone (especially synthetic) can actually decrease sperm production.
At RCA, Men Matter Too
Fertility is a shared journey—and so is responsibility. If you’re trying to conceive, planning for the future, or simply want to optimize your health, your fertility is worth understanding, testing, and supporting.
