Background. Ambiguous genitalia is an abnormality signing by the presence of atypical
appearance of external genitalia as male or female, or appear as combination of both male …

Objective: Genetic testing for male infertility is rarely performed in our country. Male infertility
is caused by chromosome number or structural problems, Y chromosome deletions and …

Human Y chromosome is made up of almost an equal amount of euchromatin and
heterochromatin. The heterochromatic region is interspersed in the distal region of the long …

Karyotype investigations using classical cytogenetics, fluorescence in situ hybridization
(FISH) and polymerase chain reaction (PCR) techniques were used for the characterization …

The aim of this study was to correlate the structural abnormalities of the Y chromosome to its
presenting clinical features to evaluate the phenotype-genotype correlation. The study was …

Disease characteristics. Y chromosome infertility is characterized by azoospermia (absence
of sperm), severe oligozoospermia (< 1 x 106 sperm/mL semen), moderate oligozoospermia …

A mosaic karyotype consisting of a 45, X cell line and a second cell line containing a normal
or an abnormal Y chromosome is relatively common and is associated with a wide spectrum …

Objective To investigate the effects of big and bit Y chromosome configurations on male
fertility and to evaluate the relevant clinical significance. Methods The relevant cases were …

To the Editor: In 1963, Shoval1 reported several individuals who had one streak gonad and
one dysgenetic testis. Later the term mixed (asymmetric) gonadal dysgenesis was applied to …

Introduction: Chromosomal abnormalities are believed to be a major contributor to the
genetic risks of infertility treatment associated with ICSI. The aim of this study is to report the …
