A Case of Balanced Translocation: 46, XY, t(9;22) (q22;q13) Accompanied with Oligospermia and Asthenospermia.

BACKGROUND

Balanced translocation of chromosomes has a negative impact on male fertility, which can easily cause clinical manifestations such as oligospermia and asthenospermia. It is necessary to conduct cytogenetic examination on men of childbearing age to guide them in their fertility.

METHODS

We report a case of balanced translocation: 46, XY, t(9;22) (q22;q13) accompanied with oligospermia and asthenospermia. The lymphocytes in peripheral blood were cultured to examine the patient's karyotype.

RESULTS

The karyotypes of the patient and the patient's wife were detected and identified as 46, XY, t(9;22) (9pter→9q22::22q13→22qter;22pter→22q13::9q22→9qter) and 46, XX, respectively. The origin of the chromosome translocation was unknown because the patient's parents did not undergo cytogenetic tests.

CONCLUSIONS

For patients with oligospermia and asthenospermia, cytogenetic examination should be carried out to obtain a healthy fetus. Prenatal diagnosis should be strictly performed to prevent the birth of children with chromosomal diseases if one partner of the couple is a carrier with abnormal chromosome structure.
