In-vitro fertilization and intracytoplasmic sperm injection in the treatment of infertility after testicular cancer.
Treatment of testicular cancer (TC) may cause infertility due to reduced sperm quality with or without an ejaculation problem. In cases of anejaculation or retrograde ejaculation, spermatozoa can be obtained by transrectal electroejaculation (TE) or testicular sperm extraction (TESE) and used for in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). In this study, 15 out of 17 couples evaluated for infertility after TC, underwent a total of 21 treatment cycles, resulting in 18 embryo transfers. Spermatozoa were obtained by TE in 16 cycles, by masturbation in three cycles and by TESE in one. In one cycle no spermatozoa were found using TESE. Fertilization and cleavage was achieved by IVF in seven cycles and ICSI in 11 cycles; average fertilization rates of 57 and 55% respectively were observed. Twelve clinical pregnancies occurred, of which 11 have been delivered or are ongoing. The ongoing pregnancy rate was 57% per cycle. These results show that infertility after testicular cancer can be treated effectively with IVF and that ICSI even permits treatment of patients who have severe oligozoospermia.
