Abstract
Spermatogenesis in mammalian testes is essential for male fertility, ensuring a continuous supply of mature sperm. The testicular microenvironment finely tunes this process, with retinoic acid, an active metabolite of vitamin A, serving a pivotal role. Retinoic acid is critical for various stages, including the differentiation of spermatogonia, meiosis in spermatogenic cells, and the production of mature spermatozoa. Vitamin A deficiency halts spermatogenesis, leading to the degeneration of numerous germ cells, a condition reversible with retinoic acid supplementation. Although retinoic acid can restore fertility in some males with reproductive disorders, it does not work universally. Furthermore, high doses may adversely affect reproduction. The inconsistent outcomes of retinoid treatments in addressing infertility are linked to the incomplete understanding of the molecular mechanisms through which retinoid signaling governs spermatogenesis. In addition to the treatment of male reproductive disorders, the role of retinoic acid in spermatogenesis also provides new ideas for the development of male non-hormone contraceptives. This paper will explore three facets: the synthesis and breakdown of retinoic acid in the testes, its role in spermatogenesis, and its application in male reproduction. Our discussion aims to provide a comprehensive reference for studying the regulatory effects of retinoic acid signaling on spermatogenesis and offer insights into its use in treating male reproductive issues.

Abstract
Non-primate mammals have two deleted azoospermia (DAZ) family genes, DAZL and Boule; genes in this family encode RNA-binding proteins essential for male fertility in diverse animals. Testicular DAZL transcription is regulated by epigenetic factors such as DNA methylation. However, nothing is known about the epigenetic regulation of Boule. Here, we explored the role of DNA methylation in the regulation of the bovine Boule (bBoule) gene. We found that a long CpG island (CGI) in the bBoule promoter was hypermethylated in the testes of cattle-yak hybrids with low bBoule expression, whereas cattle had relatively low methylation levels (P < 0.01), and there was no difference in the methylation level in the short CGI of the gene body between cattle and cattle-yak hybrids (P > 0.05). We identified a 107 bp proximal core promoter region of bBoule. Intriguingly, the differences in the methylation level between cattle and cattle-yak hybrids were larger in the core promoter than outside the core promoter. An in vitro methylation assay showed that the core promoter activity of bBoule decreased significantly after M.SssI methylase treatment (P < 0.01). We also observed dramatically increased bBoule transcription in bovine mammary epithelial cells (BMECs) after treatment with the methyltransferase inhibitor 5-Aza-dC. Taken together, our results establish that methylation status of the core promoter might be involved in testicular bBoule transcription, and may provide new insight into the epigenetic regulation of DAZ family genes and clinical insights regarding male infertility.
