Impact of reciprocal translocation t (18; 21) on male infertility and embryo development: Lessons from an oocyte-donating ICSI cycle

Abstract

Purpose: To report the outcome of intracytoplasmic sperm injection (ICSI) cycles of an oligozoospermic man with reciprocal translocation. Methods: Two ICSI cycles were given to a 29-year-old man with severe oligozoospermia and reciprocal translocation t(18;21)(p11;q21) and his wife. In the first cycle, no sperm were found in his semen and all 15 oocytes retrieved were donated to another infertile couple suffering from oligozoospermia and premature ovarian failure. In the second cycle, sperm from the husband's ejaculate were used to fertilize 13 retrieved oocytes. Results: Eleven embryos were acquired and a healthy girl was born in the oocyte-donated ICSI cycle. In the second cycle, 6 embryos were acquired and only biochemical pregnancy was achieved after three times of embryo transfer. Conclusions: By the unusual oocyte-donating ICSI procedures, impact of the new reported reciprocal translocation t (18; 21) (p11; q21) on male fertility and embryo development was suggested. © 2011 Springer Science+Business Media, LLC.
