Introduction: We reviewed the most recent advances in the genetics of MALE INFERTILITY
focusing on Y CHROMOSOME microdeletions. Materials and Methods: We searched the …

Microdeletions of the long arm of the Y chromosome involving the azoospermia factor (AZF)
region are associated with severe oligo‐or azoospermia. Abnormal androgen receptor (AR) …

The human Y chromosome is essential for human sex determination and spermatogenesis.
The long arm contains the azoospermia factor (AZF) region. Microdeletions in this region are …

Objectives: To determine Y-chromosome microdeletion of azoospermia factor (AZF) loci and
the concomitant testicular pathology in azoospermic and severely oligozoospermic infertile …

Clinical characteristics, testicular pathology, serum levels of reproductive hormones, and
genetic analysis were compared among 100 azoospermic, 20 oligozoospermic cases with …

Approximately 15% of couples in the reproductive age group worldwide are affected by
infertility, and it is estimated that about 40-50% of infertilities are of male origin. Genetic …

Objectives. To investigate the position, extent, and frequency of Y chromosome
microdeletions in Taiwanese patients presenting with nonobstructive azoospermia, and to …

Background At present, one out of six couples is infertile, and in 50% of cases, infertility is
attributed to male infertility factors. Genetic abnormalities are found in 10%‐20% of patients …

Purposes To detect the frequency and types of chromosomal anomalies with non-obstructive
azoospermia and severe oligozoospermia in Northeast China, and to compare the …

PURPOSE: The causes of male infertility are heterogeneous but more than 50% of cases
have a genetic basis. Specific genetic defects have been identified in less than 20% of …
