Male Fertility Tests: Semen Analysis and Key Diagnostic Methods Revealed
Approximately 50% of infertility cases involve male factors. Men can check fertility through semen analysis, which evaluates sperm volume, concentration, motility, and morphology. Hormone testing addresses issues like low libido or erectile dysfunction, while DNA fragmentation analysis remains controversial but may impact IVF outcomes.
Key Takeaways
Semen Analysis Parameters: Volume, Count, Motility, and Morphology Explained
Semen analysis measures four key factors: volume (fluid quantity), sperm concentration (million/mL), motility (movement percentage), and morphology (shape). Results vary due to sperm’s 72-day production cycle, requiring repeat testing for accuracy.
Hormone Testing for Erectile Dysfunction and Low Libido in Male Fertility
Hormone panels assess testosterone and other endocrine markers in men with sexual dysfunction, low sperm counts, or physical exam irregularities. Karyotype testing may be added for chromosomal abnormalities like Y microdeletion.
Sperm DNA Fragmentation and Its Role in IVF Success Rates
DNA fragmentation testing lacks routine recommendation but may help identify men with repeated IVF failures. Testicular sperm aspiration with ICSI could reduce pregnancy loss in cases of high fragmentation.
Scrotal Ultrasound for Varicoceles and Structural Abnormalities
Ultrasound detects testicular lumps, varicoceles (dilated blood vessels), or spermatoceles. While varicoceles are common, correcting them doesn’t consistently improve fertility outcomes.
Cystic Fibrosis Testing for Azoospermia Patients With No Vas Deferens
CFTR gene testing is recommended for men with azoospermia (no sperm) to identify carriers of cystic fibrosis mutations, which may cause absent vas deferens preventing sperm release.
