Nonmosaic Isodicentric Y Chromosome: A Rare Cause of Azoospermia— From Genetics to Clinical Practice

open access: yesCase Reports in Endocrinology, 2020
Azoospermia is diagnosed when no spermatozoa can be detected after centrifugation of seminal fluid on at least two separate occasions. A number of genetic disorders can be related to nonobstructive azoospermia, and in up to 15% of azoospermic males, a ...

Secretory azoospermia or non-obstructive azoospermia?

open access: yesFolia Histochemica et Cytobiologica, 2010
In the non-obstructive azoospermia versus the secretory azoospermia it is first necessary to have a clear assessment and definition and then takes care of the patient before the surgical sampling taking into account the age of the woman and in fine try ...

A new TEX11 mutation causes azoospermia and testicular meiotic arrest

open access: yesAsian Journal of Andrology, 2021
There are many unknown genetic factors that lead to infertility in nonobstructive azoospermia men. Here, we performed whole-exome sequencing in blood samples obtained from 40 azoospermia patients with meiotic arrest and found a novel c.151_154del (p ...

MRI in the evaluation of the azoospermic male

open access: yesDiagnostic and Interventional Radiology, 2020
PURPOSEWe aimed to show the usefulness of magnetic resonance imaging (MRI) in the evaluation of infertile men and its ability to distinguish obstructive from nonobstructive azoospermia.

Induced pluripotent stem cell line from a mouse model of human azoospermia with a frameshift mutation Tex11_1260Ins(TT)

open access: yesStem Cell Research, 2022
Infertility is a common disease that impacts 15% of reproductive age couples worldwide, and genetic causes are implicated in about half of those cases. Non-obstructive azoospermia is a severe form of male infertility that features spermatogenic failure ...

Sperm glyceraldehyde 3-phosphate dehydrogenase gene expression in asthenozoospermic spermatozoa [PDF]

open access: yes, 2017
It has been suggested that the energy required for sperm motility is produced by oxidative phosphorylation while glycolysis seems to be an important source for ATP transmission along the flagellum.

Microdissection testicular sperm extraction causes spermatogenic alterations in the contralateral testis [PDF]

open access: yes, 2010
Testicular sperm extraction (TESE) associated with intracytoplasmic sperm injection has allowed many men presenting non-obstructive azoospermia to achieve fatherhood.

Human obstructive (postvasectomy) and nonobstructive azoospermia – Insights from scRNA-Seq and transcriptome analysis

open access: yesGenes and Diseases, 2022
A substantial number of male infertility is caused by azoospermia. However, the underlying etiology and the molecular basis remain largely unknown. Through single-cell (sc)RNA sequencing, we had analyzed testis biopsy samples from two patients with ...

An miR-200 Cluster on Chromosome 23 Regulates Sperm Motility in Zebrafish [PDF]

open access: yes, 2018
Besides its well-documented roles in cell proliferation, apoptosis, and carcinogenesis, the function of the p53-microRNA axis has been recently revealed in the reproductive system.
