Sperm histone modifications may predict success in human assisted reproduction: a pilot study.
Purpose: Currently, assisted reproduction clinics employ various sperm selection techniques to identify the best sperm for fertilization. However, these techniques may not assess crucial sperm traits that can substantially impact embryonic quality. To address this, we propose analyzing diverse histone modifications as potential markers of sperm functionality and success in assisted reproduction techniques.
Methods: Cross-sectional pilot study including infertile male patients attending an infertility clinic in CABA, Argentina between April and August 2019 was performed. We used immunofluorescence techniques to evaluate post-translational modifications of histones in sperm and established correlations with in vitro fertilization outcome and embryo quality.
Results: Our findings indicate a negative correlation between H3K4me3 and H3K4me2 marks and fertilization rate and showed a positive correlation of this parameter with H3K9me mark. In addition, there was a positive correlation between H3K27me3 and good embryo quality.
Conclusions: This pilot study proposes a non-invasive strategy to predict embryo quality by analyzing spermatozoa prior to fertilization. The assessment of histone post-translational modifications in sperm samples could provide useful information for the recognition of epigenetic marks that could predict the health of the embryo of an assisted fertilization treatment.
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.
