Calreticulin 3 (CALR3) is considered a candidate gene in human male infertility because male, but not female, CALR3-deficient mice are infertile. To investigate the possible association between variations in CALR3 and impaired spermatogenesis in humans, we screened for mutations in human CALR3 using DNA from 892 infertile male patients and 167 proven-fertile male volunteers. The frequent appear...
The human Y chromosome harbors genes that are responsible for testis development and also for initiation and maintenance of spermatogenesis in adulthood. The long arm of the Y chromosome (Yq) contains many ampliconic and palindromic sequences making it predisposed to self-recombination during spermatogenesis and hence susceptible to intra-chromosomal deletions. Such deletions lead to copy numbe...
Background: The prevalence of infertility in the general population is 15% -20%,of this male factor responsible for 20%-40%. Semen analysis an indispensable diagnostic tool evaluation partner infertile couple.Every single couple out 10 search medical care because infertility.

BACKGROUND Mycoplasmas can cause acute and chronic diseases at multiple sites with wide-range complications and have been implicated as cofactors in diseases. The infections influenced form genital mycoplasmas specifically Mycoplasma hominis and Mycoplasma genitalium potentially affect reproductive disorders, and infertility. OBJECTIVE Isolation and molecular identification of Mycoplasma geni...
BACKGROUND Infertility is a health problem which affects about 10-20% of married couples. Male factor infertility is involved approximately 50% of infertile couples. Most of male infertility is regarding to deletions in the male-specific region of the Y chromosome. OBJECTIVE In this study, the occurrence of deletions in the AZF region and association between infertility and paternal age were ...
