Higher aneuploidy rates of chromosomes 13, 16, and 21 in a patient with globozoospermia.
OBJECTIVE
To analyze rates of chromosomal anomalies in a patient with globozoospermia.


METHODS
Case report.


METHODS
Tertiary-care infertility clinic.


METHODS
A 44-year-old man with 100% globozoospermia.


METHODS
Fixation of sperms and analysis of aneuploidies and diploidies by fluorescence in situ hybridization.


METHODS
Aneuploidy rates of chromosomes 13, 16, and 21 and diploidy rate in a patient with 100% globozoospermia.


RESULTS
The aneuploidy rates in spermatozoa from a patient with globozoospermia were significantly higher than in a normospermic man. The incidence of a disomy of the chromosomes 13, 16, and 21 was 4%, 5%, and 1%, respectively, and the nullisomy rates were 2%, 2%, and 3%, respectively.


CONCLUSIONS
This study demonstrates a positive correlation between globozoospermia and higher chromosomal aneuploidies of the chromosomes 13, 16, and 21, suggesting a higher risk of creating aneuploid embryos after intracytoplasmic sperm injection treatment for globozoospermia patients.
