Sperm quality and its freezing ability throughout the spawning season in Prochilodus lineatus and Brycon orbignyanus.

Theriogenology
The aim of this study was to determine fresh and frozen sperm quality evaluated over two spawning seasons (2013-2014; 2014-2015) in Prochilodus lineatus and Brycon orbignyanus. The spawning seasons were divided into two sampling periods: November to ...

Toxoplasma gondii transmission by artificial insemination in sheep with experimentally contaminated frozen semen.

Theriogenology
Toxoplasma gondii is a parasite considered one of the major causes of reproductive problems in sheep. Furthermore, the presence of the agent in ram semen urges the possibility of sexual transmission in this species. The aim of this study was to evalu...

Controlled ice nucleation--Is it really needed for large-volume sperm cryopreservation?

Theriogenology
Controlled ice nucleation (CIN) is an integral stage of slow freezing process when relatively large volumes (usually 1 mL or larger) of biological samples in suspension are involved. Without it, a sample will supercool to way below its melting point ...

Designing of an artificial neural network model to evaluate the association of three combined Y-specific microsatellite loci on the actual and predicted postthaw motility in crossbred bull semen.

Theriogenology
The freezing of bull semen significantly hamper the motility of sperm which reduces the conception rate in dairy cattle. The prediction of postthaw motility (PTM) before freezing will be useful to take the decision on discarding or freezing of the ge...

Comparison of Tree-Based Machine Learning Algorithms for Classification of Livestock Breeds Based On Post-Thaw Spermatological Parameters.

Veterinary medicine and science
Reproductive efficiency is a crucial determinant of livestock productivity, with sperm quality being a key factor in successful fertilization. The quantitative assessment of spermatozoa using computer-assisted sperm analysis (CASA) yields valuable ki...

Automated device for rapid sample cooling via controlled submersion.

Cryobiology
An automated device is described which enables programmable submersion in liquid nitrogen to enable rapid specimen cooling for vitrification applications. The device presented here is low-cost, portable, and compatible with a range of cryogenic conta...

[AI (ARTIFICIAL INTELLIGENCE) IN AI (ARTIFICIAL INSEMINATION)].

Harefuah
The article, which focuses only on the prevention of the sperm and/or the frozen embryo mix-up, will begin by elaborating on the acute need to prevent the next gamete and zygote mix-up scenario. Afterwards, it will explore the practical methods alrea...

Determination of the cryoprotective effect of n-methylacetamide in rabbit semen.

Cryo letters
BACKGROUND: Amides are low molecular weight cryoprotectants. N-methylacetamide (MA) is one of the cryoprotectant agents in this group.

IGF-1 stabilizes goat sperm mitochondrial transmembrane potential and reduces dna fragmentation.

Cryo letters
BACKGROUND: Antioxidant present in sperm cells protects them from oxidative damage. However, sperm are more susceptible to peroxidative damages due to the loss of these enzymes during cryopreservation and their survival and fertility may be compromis...

Follicular fluid supplemented with copper and zinc increase the maturation rate of mouse vitrified-warmed oocytes.

Cryo letters
BACKGROUND: Immature oocyte cryopreservation is a therapeutic option in assisted reproductive technology.
