Commentary: sperm DNA fragmentation testing in action [PDF]

Translational Andrology and Urology, 2017
The expert panel proposed a guideline on the clinical utility of sperm DNA fragmentation testing (1). Rapid advancement in the field of sperm DNA testing over the last two decades was summarized and structurally presented by the four clinical scenarios in an evidence-based approach.

Recombinant Monoclonal Antibodies for Detecting the Tubulin Post‐Translational Modifications Glutamylation and Lysine‐40 Acetylation

Cytoskeleton, EarlyView.
ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

In-vitro application of pentoxifylline preserved ultrastructure of spermatozoa after vitrification in asthenozoospermic patients [PDF]

, 2017
PURPOSE: To evaluate the effect of in vitro application of pentoxifylline (PX) on sperm parameters and ultrastructure after vitrification in asthenozoospermic patients. MATERIALS AND METHODS: A total of 30 asthenozoospermic semen samples (aged 25-45

Sperm DNA integrity in relation to exposure to environmental perfluoroalkyl substances – A study of spouses of pregnant women in three geographical regions. [PDF]

, 2012
Perfluoroalkyl substances (PFASs) can interfere with male reproductive function, but evidence in humansis limited. Six hundred four fertilemen(199 from Greenland, 197 from Poland and 208 from Ukraine) wereenrolled in the study.

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

Cytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Sperm DNA Fragmentation: A New Guideline for Clinicians

The World Journal of Men's Health, 2020
Sperm DNA integrity is crucial for fertilization and development of healthy offspring. The spermatozoon undergoes extensive molecular remodeling of its nucleus during later phases of spermatogenesis, which imparts compaction and protects the genetic content. Testicular (defective maturation and abortive apoptosis) and post-testicular (oxidative stress)

Differential sensitivity of midline development to mitosis during and after primitive streak extension

Developmental Dynamics, EarlyView.
Abstract Background Midline establishment is a fundamental process during early embryogenesis for Bilaterians. Midline morphogenesis in non‐amniotes can occur without mitosis, through Planar Cell Polarity (PCP) signaling. By contrast, amniotes utilize both cellular processes for developing the early midline landmark, the primitive streak (PS).

The effect of rhFSH on Sperm DNA Fragmentation and sperm parameters in Oligozoospermia Infertile Men

Research in Molecular Medicine, 2020
Background: One of the main causes of male infertility is the negative effects of oxidative stress. Follicle-stimulating hormone (FSH) plays an essential role in spermatogenesis, as well as in the maintenance of sperm DNA integrity.

The predictive value of various indicators of sperm for male fertility

Андрология и генитальная хирургия, 2016
Introduction. DNA fragmentation of sperm is one of the possible causes of reduced fertility potential of men. However, a significant correlation between conventional semen parameters and sperm DNA fragmentation was not found.

Mitochondria directly influence fertilisation outcome in the pig [PDF]

, 2006
The mitochondrion is explicitly involved in cytoplasmic regulation and is the cell's major generator of ATP. Our aim was to determine whether mitochondria alone could influence fertilisation outcome.
