Protective Effect of Intracellular Compounds of Lactobacillus plantarum on Goat Sperm Quality During Cryopreservation

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Intracellular compounds from Lactobacillus plantarum were added to a goat sperm cryopreservation extender. A concentration of 20 µL/mL improved post‐thaw sperm quality, whereas higher concentrations (80–100 µL/mL) had detrimental effects. ABSTRACT Background Cryopreservation of sperm is a key strategy for preserving and transmitting the genetic traits ...

Evaluation of microRNA expression profiles in human sperm frozen using permeable cryoprotectant-free droplet vitrification and conventional methods

Asian Journal of Andrology
For sperm cryopreservation, the conventional method, which requires glycerol, has been used for a long time. In addition, the permeable cryoprotectant-free vitrification method has been continuously studied.

Evaluation of the Effects of Nicotinic Acid and Folic Acid on Morphology, Membrane Integrity and Quality of Sperm Chromatin Concentration in Normozoospermic Men during Cryopreservation.

مجله علمی دانشگاه علوم پزشکی کردستان, 2022
Background and Aim: Sperm cryopreservation is an important assisted reproductive technique. However, due to increased production of reactive oxygen species and oxidative stress, it can impair sperm function and reduce quality of fertility.

Use of Pentoxifylline to Improve Seminal Parameters in Dogs

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
A single oral dose of pentoxifylline (10 mg/kg) administered 40 min before ejaculation significantly improved sperm concentration and progressive motility in dogs. The effect was most pronounced in oligospermic subjects, supporting pentoxifylline as a rapid, well‐tolerated adjunct therapy for canine subfertility .

Toward Practical Embryo Genomic Selection in Cattle: An Optimized Workflow Enabling High‐Accuracy Breeding Value Prediction Without Compromising Embryo Survival

The FASEB Journal, Volume 40, Issue 7, 15 April 2026.
A diameter‐guided workflow was established to define the appropriate trophectoderm (TE) biopsy area window for bovine blastocysts, with the aim of balancing embryo viability and genotyping reliability. After TE biopsy, sampled cells were subjected to DNA amplification and genomic evaluation, while the corresponding biopsied embryos were transferred to ...
