Article Abstract
Small non-coding RNAs (sncRNAs) are crucial in epigenetics, playing a significant regulatory role in the normal development and intergenerational inheritance of male reproduction. Research has shown that highly expressed sncRNAs, including miRNAs, piRNAs, and tsRNAs, are vital in maintaining male germ cell development and spermatogenesis. sncRNAs regulate gene expression, influence protein translation, and modify sperm epigenetics, contributing to male reproductive development at various stages. Abnormal expression of sncRNAs is closely linked to male infertility. Furthermore, growing evidence suggests that environmental exposures affect sperm epigenetic modifications, often leading to phenotypic changes in future generations. In this review, we summarize the types and functions of sncRNAs in male germ cells and examine their role in intergenerational inheritance due to environmental factors. It aims to provide new insights into male reproductive health and potential targets for preventing and treating male infertility and related diseases.

With the global prevalence of diabetes mellitus (DM) steadily increasing, its impact on male reproductive health has become a growing area of concern. Diabetes-induced testicular damage involves alterations in testicular cell function, hormone levels, and the integrity of the blood-testis barrier (BTB), ultimately disrupting spermatogenesis. The key pathogenic factors include hyperglycemia, oxidative stress, chronic inflammation, mitochondrial dysfunction, and the accumulation of advanced glycation end products (AGEs).

Polystyrene nanoparticles (PS-NPs) are prevalent environmental contaminants that can accumulate in biological tissues. This study investigates the effects of PS-NPs on TM4 cells, a Sertoli cell line crucial for maintaining the male spermatogenesis microenvironment.TM4 cells were exposed to PS-NPs (0-100 μg/mL) duration of 24 to 72 h.

Background: Interventions aimed to increase healthcare provider empathy and capacity to deliver person-centered care have been shown to improve healthcare seeking and outcomes. In the context of self-injectable contraception, empathetic counseling and coaching may be promising approaches for addressing "fear of the needle" among clients interested in using subcutaneous depot medroxyprogesterone (DMPA-SC). In Nigeria, the Delivering Innovation in Self-Care (DISC) project developed and evaluated an empathy-based in-service training and supportive supervision intervention for public sector family (FP) planning providers implemented in conjunction with community-based mobilization.

Background: Anxiety symptoms during pregnancy are a frequent mental health issue for expectant mothers and fathers. Research revealed that prenatal anxiety symptoms can impact parent-child bonding and child development. This study aims to investigate the prospective relationship between prenatal anxiety symptoms and general child development and whether it is mediated by parent-child bonding.
