A 47,XXY fetus conceived after ICSI of spermatozoa from a patient with non-mosaic Klinefelter's syndrome: case report.

The birth of 12 healthy infants to fathers with non-mosaic Klinefelter's syndrome has been reported so far. The spermatozoa for these pregnancies was obtained from frozen-thawed ejaculate in one pregnancy (twins) and from the testis in the remaining 10 infants. All of them had a normal karyotype. We describe a patient with non-mosaic Klinefelter's syndrome from whom a testicular biopsy was obtained and motile spermatozoa were collected. Of 16 oocytes that were injected, 14 fertilized and cleaved. Three embryos were transferred, resulting in a triplet pregnancy. Karyotype analysis from chorionic villous sampling revealed 46,XX, 46,XY and 46,XXY from the three fetuses. The affected 46,XXY fetus was reduced on the 14th gestational week. The pregnancy culminated with the birth of a healthy male and female, on the 36th gestational week, weighing 3600 and 2660 g respectively. This case report proves the presence of hyperploid spermatozoa in the seminiferous lumen, and strengthens the necessity of genetic diagnosis of the embryos or fetuses in such pregnancies to fathers with non-mosaic Klinefelter's syndrome.

["CHARGE" association].

CHARGE association represents a group of congenital anomalies with no clear etiology. The broad array of abnormalities, which involves several systems, has been the basis for the acronym CHARGE: coloboma, heart anomaly, choanal atresia, retarded growth and development, hypoplastic genitalia and ear malformation. We present 3 children with CHARGE association to illustrate the phenotypic variability and note the multidisciplinary treatment they received. It is recommended that this entity be approached in an interdisciplinary, integrated way to allow for faster diagnosis and better prognosis.
