Cases with absolute immotile sperm syndrome are rare, and include the genetic defect of immotile cilia syndrome with the absence of dynein arms in the flagellum. We attempted to increase the percentage of viable spermatozoa to improve the outcome of intracytoplasmic sperm injection (ICSI). Three couples in whom repeated analysis of the male partners indicated 100% sperm immotility underwent an in-vitro fertilization (IVF) procedure in which ICSI was performed. On their first ICSI cycle the males produced a single ejaculation while in their successive ICSI cycles they were requested to repeatedly ejaculate (two to four times) and only the last ejaculation was used. The eosin-Y test was performed on each used sample. Following their first treatment, one couple had one repeated treatment cycle, another had two and the third couple had three repeated treatment cycles. The mean percentages of viable spermatozoa were 41+/-7.4 and 71+/-6.9% in the first and repeated cycles respectively (P &lt; 0.01; t-test). Of the 39 oocytes injected in the first ICSI cycles only one (3%) was normally fertilized (2PN) compared with 41 (48%) of the 85 oocytes injected in the repeated ICSI cycles. One (3%) embryo in the first and 35 (41%) embryos in the repeated ICSI cycles respectively were obtained (P &lt; 0.001), enabling their replacement into the uterine cavity in all the repeated cycles. One woman (in a repeated cycle) conceived a twin pregnancy and delivered two healthy babies. The use of spermatozoa from repeated ejaculation is recommended in men with absolutely immotile spermatozoa so as to obtain significantly better viability and fertilizing capacity.
