Yes, conception via IUI (Intrauterine Insemination) is certainly possible with a sperm count of 13 million/mL (mild oligozoospermia).
The WHO reference lower limit for normal sperm concentration is 15 million/mL, meaning 13 million/mL is only slightly below standard benchmarks. For IUI, the critical metric is the Total Motile Sperm Count (TMSC) post-wash. If a semen sample yields at least 5 to 10 million progressively motile sperm after processing, IUI maintains good success rates. Because you have already fathered a child previously (secondary subfertility), your biological baseline is favorable.
Next Steps
Consult a Reproductive Endocrinologist / Fertility Specialist: Review the complete semen analysis together—specifically checking progressive motility (%) and normal morphology (%), as count alone does not dictate fertility potential.
Repeat Semen Analysis (in 3 to 4 Weeks): Sperm counts fluctuate significantly based on recent fever, stress, or lifestyle. A repeat sample following 2–5 days of sexual abstinence ensures accuracy.
Evaluate Secondary Causes with an Andrologist: Check for common reversible factors like a varicocele (via scrotal ultrasound), subclinical infections, or hormonal variations (Total
Testosterone,
FSH,
LH).
Assess Partner's Ovarian Reserve & Tubal Patency: Ensure your partner's reproductive evaluation (fallopian tube patency via HSG and ovarian reserve via
AMH/antral follicle count) is current before initiating IUI cycles.
Health Tips
Avoid high scrotal temperatures and unprescribed fertility supplements. Prolonged hot baths, saunas, keeping laptops directly on the lap, or tight synthetic underwear elevate testicular temperature and lower sperm parameters.
Targeted Lifestyle Optimization: Sperm takes approximately 72–90 days to develop (spermatogenesis). Quitting smoking/alcohol, maintaining daily moderate exercise, and taking targeted antioxidant therapy (CoQ10, L-Carnitine, Zinc,
Vitamin C and E) under medical guidance can noticeably improve sperm quality within 3 months.
