Introduction: Sperm immobility is a condition in which sperm are viable but not motile. We reported three patients with sperm immobility, who underwent testicular sperm extraction-intracytoplasmic sperm injection.
Case presentation: In case 1, a 32-year-old patient with sperm immobility had previously undergone intracytoplasmic sperm injection with ejaculated sperm; however, pregnancy was unsuccessful. testicular sperm extraction-intracytoplasmic sperm injection was performed at our clinic, and pregnancy was achieved. In case 2, a 23-year-old patient with clinical varicocele whose semen analysis revealed sperm immobility underwent varicocelectomy, without improvement. Using the hypo-osmotic swelling test technique, testicular sperm extraction-intracytoplasmic sperm injection was performed; however, pregnancy was not achieved. In case 3, a 44-year-old patient with sperm immobility underwent testicular sperm extraction, and motile sperm were retrieved. testicular sperm extraction-intracytoplasmic sperm injection using these sperm resulted in pregnancy.
Conclusion: Although testicular sperm extraction-intracytoplasmic sperm injection is not considered a solution in patients with sperm immobility, pregnancies were achieved. testicular sperm extraction-intracytoplasmic sperm injection may be successful in some cases in which ejaculated sperm intracytoplasmic sperm injection is unsuitable.
