Objective: This study aimed to explore the correlation between ambient particulate matter 2.5 (PM2.5) concentration and sperm quality among northern Thai men exposed to the seasonal air pollution from the agricultural burning process.
Methods: The demographic data and semen analysis of Thai men living in Chiang Mai, Thailand, who visited the infertile clinic were collected. The correlation test between the monthly amount of PM2.5 and sperm quality was carried out.
Results: From 2017 to 2021, 1,109 Thai men visited the Infertile Clinic. The correlation test between PM2.5 and sperm quality in years with a better climate revealed a weak positive correlation between the mean PM2.5 and percentage of progressive motile sperm and normal morphology (r=0.08, p=0.05 and r=0.1, p=0.02). However, there was a negative correlation between the mean PM2.5 and sperm concentration, progressive motility and normal sperm morphology during the years with a higher amount of ambient PM2.5, and especially PM2.5 exposure 3 months before semen collection (r=-0.12, p=0.01, r=-0.11, p=0.003, r=-0.15, p=0.004).
Conclusions: Exposure to a high amount of PM2.5 air pollution negatively affects sperm quality.

Cryopreservation of rooster semen is a reproductive technology carried out to boost genetic gain and productivity in commercial flocks of chicken. However, semen freezing significantly reduces the quality and fertilizing potential of spermatozoa. This study examined cryoprotective effects of the mitochondria-targeted antioxidant mitoquinol mesylate added to the freezing extender by assessing post-thaw characteristics of rooster sperm.

The cooling procedure markedly diminishes the quality of guinea pig () sperms, primarily because their membranes are highly susceptible to this process. This susceptibility triggers the generation of reactive oxygen species and free radicals, ultimately leading to lipid peroxidation in the sperm membrane. Surprisingly, there has been a lack of research on the use of Tris-based extenders to safeguard guinea pig sperm under refrigeration conditions.

Background: Para-phenylenediamine (PPD) is a crystalline solid that belongs to the aromatic amine group, widely used in the manufacturing of various dyes. PPD exhibits toxic effects on female hormone stability, ovarian function, and embryo development. Although studies have shown that PPD exposure can damage oocyte quality in female mice, research on its effects on male reproductive capability, particularly on human sperm quality and function, is limited.

Medicinal herbs, such as the ant nest plant (), are promising for the management of diabetes mellitus-associated infertility. The aim of this study was to evaluate the biological activity of the ant nest plant and its capacity to mitigate the adverse effects of alloxan-induced diabetes on testicular morphology, epididymal function, and sperm quality in male rats. The tuber of the ant nest plant was extracted using methanol and then subjected to phytochemical screenings.

Paclitaxel (PAC), derived from Taxus brevifolia, is used to treat solid tumours but causes reproductive toxicity due to oxidative stress, affecting sperm quality and testicular tissue. Nerolidol (NRL), an antioxidant sesquiterpene alcohol, has not been studied for its potential to reduce PAC-induced reproductive damage. This study investigates NRL's ability to mitigate PAC-induced reproductive toxicity in rats.
