An infertile male with balanced Y;19 translocation. Review of Y;autosome translocations.
Cytogenetic studies on a phenotypically normal male, presenting with infertility, revealed a balanced Y;19 translocation - 46,XY,t (Y;19) (q11; p or q13). The patient had a normal hormone profile, but semen analysis showed immature cells in the fluid. The possible mechanisms causing the infertility are discussed. An extensive review of the literature of Y ; autosome translocations indicates that there are 2 types, those in which the broken segment of the Y is translocated to the short arm or centromeric region of an acrocentric chromosome, and those in which the Y material is translocated onto a long or short arm region of a non-acrocentric chromosome. The first type is less frequently associated with infertility and hypogonadism than the second type. There is presumptive evidence that the first type is non-random.
