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 …

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

Cytogenetic studies in infertile men showed that chromosomal anomalies were more
frequent in these patients than in general population. Sex chromosome anomalies, specially …

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 …

Background: The present study offers our contribution on the topic by a retrospective
analysis of the prevalence of chromosomal abnormalities in a population of Iranian infertile …

ABSTRACT Infertility affects approximately 10%-15% of couples in reproductive age. There
is a complex correlation between genetics and infertility. Several factors affect on …

Background: The sperm count and function may be affected by KARYOTYPE abnormalities
or microdeletion in Y chromosome. These genetic abnormalities can probably transmit to the …

Objective: In a half of all childless partnerships the infertility is caused by the male.
Chromosomal abnormalities are more prevalent in infertile men compared to fertile men …

Methods 305 infertile couples were investigated. All male partners were referred to a
complete andrological work-up with physical examination, determination of hormones, HIV …

About 15% of couples have infertility problems, half of which are related to male factors.
