Infertility has been reported as one of the most common reproductive impairments, affecting nearly one in six couples worldwide. A large proportion of infertility cases are diagnosed as idiopathic, signifying a deficit in information surrounding the pathology of infertility and necessity of medical intervention such as assisted reproductive therapy. Small noncoding RNAs (sncRNAs) are well-established regulators of mammalian reproduction. Advanced technologies have revealed the dynamic expression and diverse functions of sncRNAs during mammalian germ cell development. Mounting evidence indicates sncRNAs in sperm, especially microRNAs (miRNAs) and transfer RNA (tRNA)-derived small RNAs (tsRNAs), are sensitive to environmental changes and mediate the inheritance of paternally acquired metabolic and mental traits. Here, we review the critical roles of sncRNAs in mammalian germ cell development. Furthermore, we highlight the functions of sperm-borne sncRNAs in epigenetic inheritance. We also discuss evidence supporting sncRNAs as promising biomarkers for fertility and embryo quality in addition to the present limitations of using sncRNAs for infertility diagnosis and treatment.

Intrauterine growth retardation (IUGR) has become a difficult problem in animal husbandry and is often accompanied by the occurrence of metabolic syndrome. tRNA-derived small RNAs (tsRNAs) are a novel class of regulatory small noncoding RNAs. However, the involvement of tsRNA in regulating the mechanism of IUGR remains unclear.

MicroRNAs (miRNAs) are non-coding, endogenous small single-stranded RNA molecules involved in post-transcriptional regulation of gene expression. It has been demonstrated that dysregulation of miRNA plays a major role in tumor formation, proliferation, and metastasis. Therefore, the delivery of anti-miRNA oligonucleotides to block the activity of these oncogenic miRNAs is a high-potential anti-cancer therapy approach.

Pre-eclampsia (PE) is a serious condition affecting 2-8% of pregnancies worldwide, leading to high maternal and fetal morbidity and mortality. MicroRNAs (miRNAs), small non-coding RNA molecules, have emerged as potential biomarkers for various pregnancy-related pathologies, including PE. MiRNAs in plasma and serum have been extensively studied, but urinary miRNAs remain underexplored, especially during early pregnancy.

When a body is discovered at a crime or murder scene, it is crucial to examine the body and estimate its postmortem interval (PMI). Accurate estimation of PMI is vital for identifying suspects and providing clues to resolve the case. MicroRNAs (miRNAs or miRs) are small non-coding RNAs that remain relatively stable in the cell nucleus even after death-related changes occur.
