Objective: To analyze the effect of sperm DNA fragmentation index (DFI) on the outcomes of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).
Methods: Literature search was conducted on English databases PubMed, Cochrane, and Embase to obtain eligible studies.
Results: A total of 11 cohort studies were included and analyzed using the random effects model. The results illustrated that the IVF fertilization rate (RR = 0.94, 95% CI: 0.77-1.14, = 0.61), pregnancy rate (RR = 0.83, 95% CI: 0.57-1.21, = 0.32), and live birth rate (RR = 0.53, 95% CI: 0.16-1.80, = 0.31) in the high DFI group were statistically insignificant with those in the low FI group. The correlations between DFI and ICSI fertilization rate (RR = 0.79, 95% CI: 0.52-1.18, = 0.25), pregnancy rate (RR = 0.89, 95% CI: 0.74-1.06, = 0.18), and live birth rate (RR = 0.89, 95% CI: 0.70-1.14, = 0.36) were also not statistically significant.
Conclusion: This study has observed no significant correlation between sperm DFI and assisted reproductive outcomes. Multicenter large-sample clinical trials are required to conclusively determine the impact of DNA damage on the clinical outcomes of assisted reproduction.

This study evaluated the effectiveness of Percoll® density gradient centrifugation (Percoll-DGC) for selecting bull epididymal sperm prior to conventional slow (CS) or ultra-rapid (UR) freezing and its effects on sperm quality. Fifteen pooled samples from 30 epididymides (2 different samples/pool) of 15 bulls were split into two aliquots assigned to either CS or UR freezing. Samples were either selected using Percoll-DGC (40/80 %) or left non-selected (control), resulting in four pre-freezing treatments: Percoll-CS, Control-CS, Percoll-UR, and Control-UR.

Bisphenol A (BPA), a common endocrine disrupting chemical (EDC), has shown detrimental effects on sperm quality and function in experimental models. However, epidemiological evidence is inconsistent and also there exists a notable lack of data on its analogues, such as bisphenol F (BPF) and bisphenol S (BPS). To investigate the relationships between BPA, BPF and BPS exposures and sperm DNA damage, we conducted a cross-sectional study recruiting 474 Chinese men from an infertility clinic in Wuhan, China.

Background: In the cryopreservation process, rooster spermatozoa are vastly sensitive to reactive oxygen species (ROS). This study aimed to investigate the effects of Lake extender supplemented via Cysteamine (CYS) on the quality and fertility characteristics of rooster semen during the cryopreservation process.
Methods: Semen samples were collected from 10 proved Ross-308 roosters, diluted and cryopreserved in the Lake extender which contained 0, 1, 2, 4, and 8 mM of CYS (C-0, C-1, C-2, C-4, and C-8, respectively).

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.

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.
