New insights into posttranslational modifications of proteins during bull sperm capacitation
BackgroundDue to the unique nature of spermatozoa, which are transcriptionally and translationally silent, the regulation of capacitation is based on...

Bull spermatozoa selected by thermotaxis exhibit high DNA integrity, specific head morphometry, and improve ICSI outcome
BackgroundSperm migration by thermotaxis is a guidance mechanism that operates along the oviduct and it has proved to be a valid method for selecting...

Isolation of Campylobacter fetus subsp. venerealis from seminal vesicle of a naturally challenged bull
Campylobacter fetus is a well-recognized pathogen that affects reproductive rate in cattle. In the present study, two Angus bulls were kept (39 days)...

Uncovering sperm metabolome to discover biomarkers for bull fertility
BackgroundSubfertility decreases the efficiency of the cattle industry because artificial insemination employs spermatozoa from a single bull to...

Expression of miR-138 in cryopreserved bovine sperm is related to their fertility potential
BackgroundMicroRNAs (miRNAs) are small, single-stranded, non-coding RNA molecules of 22–24 nucleotides that regulate gene expression. In the last...

Non-Invasive Identification of Sex in Cultured Bovine Embryos by UHPLC-MS/MS Metabolomics
IntroductionDifferent gene expression between male and female bovine embryos leads to metabolic differences.
ObjectiveWe used UHPLC-MS/MS to...

Sperm-oocyte interplay: an overview of spermatozoon’s role in oocyte activation and current perspectives in diagnosis and fertility treatment
The fertilizing spermatozoon is a highly specialized cell that selects from millions along the female tract until the oocyte. The paternal components...

Morphological assessment of free-spawned sperm in scleractinian coral: a relationship between cell morphology and motility
Although the quality of the spermatozoa is a key factor for reproductive success, there is few information describing the sperm quality for most...

Harnessing male germline epigenomics for the genetic improvement in cattle
Sperm is essential for successful artificial insemination in dairy cattle, and its quality can be influenced by both epigenetic modification and...
-
Structural Analysis of Sperm Centrioles Using N-STORM
A prominent technical barrier when imaging swimming sperm is capturing a singular sperm cell’s head and tail position simultaneously at a high...

Sperm-cell Detection Using YOLOv5 Architecture
Infertility has become a severe health issue in recent years. Sperm morphology, sperm motility, and sperm density are the most critical factors in...
-
Energetics of Fish Spermatozoa
Fish spermatozoa need to perceive a signal from the external milieu so as to activate their motility. The osmolarity and/or ionic composition of the...

Some Aspects of the Role of Phosphorylation in Regulation of Spermatozoa Motility in Microgravity
AbstractThe review describes mechanisms of regulating the spermatozoa motor activity. The authors present the enzymes involved in phosphorylation of...
-
The Role of Extracellular Vesicles in Sperm Function and Male Fertility
Within the reproductive tract, distinct cell types must have precisely controlled communication for complex processes such as gamete production,...
