Abstract
Purpose: This study investigates the role of cation channel sperm associated 2 (CATSPER2) and sperm flagella 2 (SPEF2) genes in boar spermatogenesis, focusing on their association with sperm quality traits in boars.
Methods: Utilizing targeted next-generation sequencing, we identified and genotyped two polymorphisms in CATSPER2 (rs341636020G > A, rs326912346G > T) and three variants in SPEF2 (rs320839956A > G, rs334209514C > A, rs325319860C > T) across three boar breeds (Duroc, n = 181; Landrace, n = 87; Large White, n = 52).
Results: Our results confirmed the presence of the specified single nucleotide polymorphisms (SNPs), adhering to association study criteria. In CATSPER2, significant associations were detected between rs341636020G > A and sperm curvilinear velocity (VCL) in Duroc and Landrace boars, and between rs326912346G > T and straight velocity (VSL) in Duroc and Large White boars. For SPEF2, rs320839956A > G was significantly linked to sperm viability in Duroc and Landrace and to sperm concentration (SCON) in Large White boars. Additionally, rs334209514C > A and rs325319860C > T showed significant associations with SCON and VCL respectively, in Doruc and Landrace boars.
Conclusions: Overall, our findings suggest that CATSPER2 and SPEF2 SNPs significantly impact boar sperm quality traits. These genetic markers have the potential to enhance boar fertility through selective breeding programs, contributing to the optimization of reproductive performance in pigs.
期刊介绍：
The Journal of Assisted Reproduction and Genetics publishes cellular, molecular, genetic, and epigenetic discoveries advancing our understanding of the biology and underlying mechanisms from gametogenesis to offspring health. Special emphasis is placed on the practice and evolution of assisted reproduction technologies (ARTs) with reference to the diagnosis and management of diseases affecting fertility. Our goal is to educate our readership in the translation of basic and clinical discoveries made from human or relevant animal models to the safe and efficacious practice of human ARTs. The scientific rigor and ethical standards embraced by the JARG editorial team ensures a broad international base of expertise guiding the marriage of contemporary clinical research paradigms with basic science discovery. JARG publishes original papers, minireviews, case reports, and opinion pieces often combined into special topic issues that will educate clinicians and scientists with interests in the mechanisms of human development that bear on the treatment of infertility and emerging innovations in human ARTs. The guiding principles of male and female reproductive health impacting pre- and post-conceptional viability and developmental potential are emphasized within the purview of human reproductive health in current and future generations of our species.
The journal is published in cooperation with the American Society for Reproductive Medicine, an organization of more than 8,000 physicians, researchers, nurses, technicians and other professionals dedicated to advancing knowledge and expertise in reproductive biology.
