Objective : Infertility is the inability of a couple to conceive after one and half year of unprotected sex.Infertility is an inability of a person to reproduce, in its normal state or condition. Male infertility is considered as a major problem all over the world. The aim of this study was to investigate the association of the CYP1A1 polymorphisms with idiopathic non-obstructive azoospermia in...

Abstract Background Male sex reversal syndrome is a rare genetic cause of male infertility with an overall incidence 1/20,000–1/100,000 males. There mismatching between the make-up and apparent clinical features. The presentation such cases variable ranging from ambiguous genitalia at birth, failed puberty, up to normal phenotype hypogonadism. exact molecular bases this are still unclear. Most ...

Abstract A father’s lifetime experience is a major risk factor for range of diseases in an individual. The influences exposure can also be transmitted to offspring. Previous studies demonstrated that plasticisers damage the male offspring reproductive system, but link between mammalian research and human non-obstructive azoospermia remains underexplored. Here, we analysed reproduction-related g...

It has been established that the Y chromosome carries genes required for spermatogenesis and male fertility. For many decades worldwide screening for gene identification has been conducted in research laboratories. However, it has been a difficult process in identifying such genes (i.e. causative mutations) which could explain the phenotypic variation and could be potentially used as markers fo...

adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. in spite of their usefulness, the construction of adenoviral vectors (adv) is a cumbersome and lengthy process that is not readily amenable to the generat...

The Deleted in AZoospermia (DAZ) genes encode potential RNA-binding proteins that are expressed exclusively in prenatal and postnatal germ cells and are strong candidates for human fertility factors. Here we report the identification of an additional member of the DAZ gene family, which we have called BOULE. With the identification of this gene, it is clear that the human DAZ gene family contai...

BACKGROUND Azoospermia is the medical condition of a man not having any measurable level of sperm in his semen. Follicle stimulating hormone (FSH) is a member of the glycoprotein hormone family that plays an important role in human reproduction because of its essential role in normal spermatogenesis. Various Single Nucleotide Polymorphisms (SNPs) have been reported within FSH receptor (FSHR) ge...

In a subset of infertile men, a spectrum of spermatogenic defects ranging from a complete absence of germ cells (sertoli cell only) to oligozoospermia is associated with microdeletions of the DAZ (deleted in azoospermia) gene cluster on human distal Yq. DAZ encodes a testis-specific protein with RNA-binding potential recently derived from a single-copy gene DAZL1 (DAZ-like) on chromosome 3. Y c...
