Successful pregnancies after using immotile spermatozoa from ejaculate, epididymis and testis

Abstract Objective: To assess the efficacy of intracytoplasmic sperm injection (ICSI) in term of pregnancy rate with immotile spermatozoa from ejaculate, epididymis and testis. Study design: A retrospective study was conducted between January 1998 and March 2001. We performed intracytoplasmic sperm injection with immotile spermatozoa, in 160 couples during 172 cycles. Results: The birth rate per cycle was 38.4% in immotile spermatozoa from ejaculate, 35.4% from testis and 38.7% from epididymis. Conclusion: This retrospective analysis shows that immotile spermatozoa retrieved from epididymis or testicle gives similar fertilization and pregnancies rates as immotile spermatozoa from ejaculate.
