Correlation between Y chromosome microdeletion and male infertility.

Multiplex-Polymerase Chain Reaction for Detecting Microdeletions in The Azoospermia Factor Region of Y Chromosome in Iranian Couples with Non-Obstructive Infertility and Recurrent Pregnancy Loss

Objective Approximately 15 percent of couples are infertile. The male factor is responsible for approximately 50% of the cases. One of the main genetic factors playing a role in male infertility is Y chromosomal microdeletion within the proximal long arm of the Y chromosome (Yq11), named azoospermia factor (AZF) region. Recent studies have also demonstrated that there is a potential connection ...

O-4: Association of Y Chromosome Microdeletion with Spermatogenic Impairment and Infertility in Human Males with High Concentration of Seminal Hexachlorocyclohexane (HC)

Background: The Y chromosome microdeletion is one of the best-documented causes of male infertility but the factors responsible for Y chromosome microdeletions in spermatozoa remain unresolved. However, the environmental pollutants are known to damage DNA in differentiating and maturing germ cells in the male reproductive tract. In view of this, the objective of the present study was to explore...

Y Choromosomal Microdeletion Screening in The Workup of Male Infertility and Its Current Status in India

I-37: Genome Instability and DNA Damage in Male Somatic and Germ Cells Expressed as Chromosomal Microdeletion and Aneuploidy Is A Major Cause of Male Infertility

Background: Sperm chromatin insufficiencies leading to low sperm count and quality, infertility and transmission of chromosomal microdeletion and aneuploidies to next generations can be due to exposure to environmental pollutions, chemicals and natural or manmade ionizing radiation. In this project which has continued for more than 10 years and is unique in many technical aspects in Iran and in...

I-6: Azoospermia Factor in Male Infertility

Background The human Y chromosome is essential for human sex determination and male germ cell development and maintenance. In 1996, Vogt et al. identified three recurrently deleted regions in Yq11 termed the azoospermia factor (AZF). The AZF region is subdivided into three non-overlapping sub-regions called AZFa, AZFb and AZFc and microdeletion in these regions is the most important etiology of...
