Male factor infertility is involved in almost half of all infertile couples. Lack of the ejaculated sperm owing to testicular malfunction has been reported in 6-10% of infertile men, a condition named nonobstructive azoospermia (NOA). In this study, we investigated untargeted metabolomic profiling o...

Despite timely and successful surgery, 32% of patients with bilateral and 10% with unilateral cryptorchidism will develop azoospermia. Cryptorchid boys at risk of azoospermia display a typical testicular histology of impaired mini-puberty at the time of the orchidopexy. During mini-puberty increased...

We collected blood samples of two non-obstructive azoospermia patients, and performed whole exome sequencing to explore the causal mutations for male infertility.

We analyzed gene expression profiles of human testicular biopsies in men with idiopathic nonobstructive azoospermia who underwent therapy with hCG/rFSH. Using new generation oligonucleotide microarray platform GeneChip® Human Gene 1.0 ST, we identified genes which could be potential prognostic bio...

The proteome and phosphoproteomics changes were quantified in seminal plasma extracellular vesicles among healthy individuals with normal sperm, nonobstructive azoospermia and obstructive azoospermia using TMT 10-plex by LC-MS/MS.

We analyzed gene expression profiles of human testicular biopsies in men with idiopathic nonobstructive azoospermia. Using new generation oligonucleotide microarray platform GeneChipM-BM-. Human Gene 1.0 ST, we identified genes which could be potential biomarkers of azoospermia and molecular indica...

The project aimed to compare testicular proteomes from patients with obstructive and non-obstructive azoospermia in order to identify molecular signatures involved in spermatogenesis as well to identify candidate biomarkers for discriminating between different types of azoospermia. The samples used ...

Although piwi-interacting RNAs (piRNAs) play pivotal roles in spermatogenesis, little is known about piRNAs in the seminal plasma of infertile males. In this study, we systematically investigated the profiles of seminal plasma piRNAs in infertile males to identify piRNAs that are altered during infe...

Infertility affects about one in six couples attempting pregnancy, with the man responsible in approximately half of the cases. Because the pathophysiology underlying azoospermia is not elucidated, most male infertility is diagnosed as idiopathic. Genome-wide gene expression analyses with microarra...

Azoospermia, characterized by the absence of spermatozoa in the ejaculate is a common cause of male infertility with a poorly characterized etiology. Exome sequencing analysis of two azoospermic brothers allowed the identification of a homozygous splice mutation in SPINK2, encoding a serine protease...
