One normal child and a chromosomally balanced/normal twin after intracytoplasmic sperm injection in a male with a de-novo t(Y;16) translocation.
A balanced translocation t(Y;16)(q11.21;q24) is described in a male with severe oligoasthenoteratozoospermia (OAT). Before having a chromosome investigation, the patient and his partner had undergone intracytoplasmic sperm injection (ICSI) treatment resulting in the birth of a healthy 46,XX child. After detection of the t(Y;16) translocation, the couple opted for further ICSI treatment, although they were extensively counselled on the risk of having chromosomally unbalanced offspring. This treatment resulted in a twin pregnancy, one with a 46,XX karyotype and the other a 46,X,t(Y;16) (q11.21;q24) karyotype, the same as the father. After an uncomplicated pregnancy two healthy children were born. We conclude that patients with a Y/autosome translocation as a cause of OAT can have chromosomally normal children after ICSI treatment.
