Recent studies support the influence of paternal lifestyle and diet before conception on the health of the offspring via epigenetic inheritance through sperm DNA methylation, histone modification, and small non-coding RNA (sncRNA) expression and regulation. Smoking may induce DNA hypermethylation in genes related to anti-oxidation and insulin resistance. Paternal diet and obesity are associated with greater risks of metabolic dysfunction in offspring via epigenetic alterations in the sperm.

: Recurrent pregnancy loss (RPL) affects numerous couples worldwide and has traditionally been attributed mainly to maternal factors. However, recent evidence highlights significant paternal influences on pregnancy viability and outcomes. This review aims to comprehensively examine male contributions to pregnancy loss, focusing on underlying mechanisms, novel biomarkers, and integrated strategies for improved reproductive success.

Wuxi School of Medicine, Jiangnan University, 214002 Wuxi, Jiangsu, China.
Background: The massive harmful effects of cigarette (tobacco) smoking on reproduction and fecundity are apparent. Even smoking cessation is often suggested for infertility patients by clinic doctors, while the impact of smoking cessation on semen quality in patients with oligoasthenospermia is uncovered.
Methods: Ninety oligoasthenospermia patients with long tobacco smoking history were directed by andrology doctors to cease smoking, and their cessation was followed up for 3 to 6 months.

Tobacco smoke has numerous adverse effects on both human and animal health, including impaired reproductive function. Recent research has explored environmental exposure in dogs, investigating various biological matrices. However, no data are currently available on the presence of cotinine, a nicotine metabolite, in the canine ejaculate.
