Special Issue Information

Dear Colleagues,

High semen quality is a basic condition for male fertility. Progress in the field of utility traits of domestic animals does not support maintaining high male fertility. Therefore, research is needed on effective methods of semen assessment and factors determining sperm quality. The purpose of this Special Issue on “Sperm Quality Assessment in Domestic Animals” is to present the latest scientific achievements in the use of advanced techniques for assessments of sperm. We also invite original research articles that concern methods of semen preservation and storage. We look forward to receiving your contributions.

Original research articles and reviews are welcome.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Sperm motility is a key factor influencing male fertility and is associated with metabolic and lipid profiles across species. The aim of this study was to investigate the relationship between sperm motility and the seminal plasma lipid profile in Simmental bulls, and to identify key lipids potentially influencing sperm motility. Semen samples were collected from 26 healthy Simmental bulls with an average age of 4.9 years. Sperm quality was evaluated using computer-assisted sperm analysis (CASA). Based on motility, the samples were divided into two groups: high sperm motility (HSM > 65%) and low sperm motility (LSM < 65%). Compared to the LSM group, the HSM group exhibited significantly higher sperm viability, motility, straight-line velocity, beat-cross frequency, and sperm acrosome integrity, while the sperm malformation rate was lower (p < 0.05). Lipid profiles were determined using LC-MS/MS, and 40 differential lipids were identified by multivariate statistical analysis. Among them, 39 lipids were upregulated in the LSM group compared to the HSM group. They were primarily triglycerides and carnitines, mainly involved in four metabolic pathways related to glycerophospholipid and linoleic acid metabolism. Notably, PC (16:0/20:4; 14:0/18:3), LPC (22:4/0:0; 22:6/0:0), and PE (14:0/18:1; 18:1/20:3) were diagnosed with great accuracy (AUC > 0.7), which means they may serve as potential biomarkers for sperm motility.
