The effects of an immunosuppressive factor (ISF) isolated from boar seminal vesicle fluid on in vitro and in vivo mouse development were investigated. It was found that the zona pellucida of porcine and mouse oocytes pre-incubated with ISF reacted in indirect immunofluorescence with antibodies against ISF. Further results indicated that the boar ISF had no effect on embryo development.

Artificial insemination (AI), as an efficient assisted reproduction technology, can help the livestock industry to improve livestock and poultry breeds, optimize production performance and improve reproductive efficiency. AI technology has been widely used in pig production in China, but boar fertility affects the effectiveness of AI, and more and more studies have shown that there are significant differences in the fertility of boars with similar semen quality indicators. Therefore, this study aimed to identify biomarker molecules that indicate the level of boar fertility, which is important for improving the efficiency of AI.

Background: Seminal plasma is an important component of semen and has a significant effect on sperm function. However, the relationship between seminal plasma and sperm freezing capacity has not been fully studied.

Purpose: Exploring metabolites and proteins related to the boar sperm freezing capacity in seminal plasma, by metabolomic and proteomic approaches, and directly verifying the protective effect of seminal plasma on the cryopreservation of boar sperm using high and low freezability seminal plasma as base freezing extender.

Sperm cells are highly susceptible to oxidative stress, which decreases their motility and fertility. However, glutathione (GSH) plays a critical role in protecting sperm cells from oxidative damage, a common byproduct of mitochondrial oxidative phosphorylation. On the other hand, GSH biosynthesis in sperm is limited by the availability of cysteine (Cys), which is inherently unstable and found at low concentrations in boar seminal plasma.

Background: Extracellular vesicles (EVs) are essential for cell-to-cell communication because they transport functionally active molecules, including proteins, RNA, and lipids, from secretory cells to nearby or distant target cells. Seminal plasma contains a large number of EVs (sEVs) that are phenotypically heterogeneous. The aim of the present study was to identify the RNA species contained in two subsets of porcine sEVs of different sizes, namely small sEVs (S-sEVs) and large sEVs (L-sEVs).

The second form of gonadotropin-releasing hormone (GnRH-II) and its receptor (GnRHR-II) are abundantly produced within the porcine testis and immunolocalize within the seminiferous tubules, suggesting a role in spermatogenesis and/or sperm function. The objective of this study was to quantify GnRH-II and GnRHR-II abundance within boar reproductive tract tissues and examine their role in porcine sperm function. Immunoblotting revealed GnRHR-II abundance was 12-fold greater (P < 0.
