Summary: This study evaluated the expression of the follicle-stimulating hormone receptor (FSHR) in human spermatozoa and its effects on sperm function. The results showed that FSHR is expressed in the post-acrosomal segment, neck, midpiece, and tail of human spermatozoa, with no difference in localization between patients and controls. Incubation with FSH increased FSHR expression in patients. Furthermore, FSH incubation had a negative effect on sperm motility and mitochondrial function in both patients and controls, but more severely in controls. FSH also activated the AKT(473) signaling pathway.

Summary: It has been found that advanced age negatively affects sperm parameters and DNA integrity, with potential impacts on in vitro fertilization success. This study aimed to understand the association between advanced paternal age and sperm parameters, DNA integrity, and DNA methylation profile. The findings showed that individuals over 40 years old had significantly higher levels of DNA fragmentation (15% versus 9%, p = 0.04) and lower global methylation levels (6% in the young group versus 2% in the old group, p = 0.03). These results emphasize the importance of assessing sperm DNA fragmentation, particularly after the age of 40, in fertility evaluation and treatment.

Summary: Nowadays, there is a growing adoption of In Vitro Fertilization (IVF) techniques. A promising strategy is the use of non-physiological materials and naturally derived compounds for advanced sperm preparation methods. The study showed that MoS2/Catechin nanoflakes and catechin (CT) did not have any negative effects on sperm capacitation, while adding a specific concentration of CT increased the fertilizing ability of sperm in an IVF assay. These findings suggest that catechins and new materials obtained using natural or bio compounds could enhance current sperm capacitation strategies.

Summary: In recent years, there has been a push to develop new in vitro techniques for ecotoxicology and environmental risk assessment, with fish spermatozoa being considered a promising tool due to their simplicity and availability. However, further studies are needed to establish a clear correlation between in vitro and in vivo toxicities when using fish spermatozoa.

Summary: This review discusses the impact of advanced paternal age on offspring and explores the relationships between advanced paternal age and fertility, perinatal health, cancer risk, genetic diseases, and neurodevelopmental effects. The potential mechanisms underlying the effects of advanced paternal age on germ cells and the current state of reproductive risk management are also presented. The challenges and approaches to address this important clinical dilemma are outlined.

Summary: This study provides in-depth characterization of the perinuclear theca (PT) of boar spermatozoa through subcellular fractionation, revealing 1802 identified proteins. The PT was found to be enriched in proteins involved in sperm-egg fusion and egg activation, as well as endoplasmic reticulum (ER) proteins and the ER-stress response. Protein-protein interaction analysis visualized an intricate network of PT protein complexes, including proteasome subunits.

Summary: Sperm is crucial for reconstitution of embryonic diploidy and specialized developmental functions. It triggers activation through PLC-zeta after gamete fusion, impacting fertilization and chromosome segregation. Sperm-specific epigenetic factors also contribute to embryonic development and have implications for assisted reproduction treatments.

Summary: cFEE improves gamete interaction in humans by enhancing sperm movement parameters and increasing the percentage of hyperactivated sperm. However, it does not significantly impact the analyzed mitochondrial bioenergetic parameters, indicating that it may act through a more efficient use of energy resources.

Summary: This study aimed to investigate the effect of Lactobacillus plantarum secretions on sperm motility, morphology, and DNA fragmentation when added to the sperm freezing medium. The results showed that the addition of 10^8 colony-forming units/mL Lactobacillus plantarum secretions did not significantly decrease sperm motility after thawing. Furthermore, the Lactobacillus plantarum secretions were found to protect sperm DNA integrity more effectively in the non-normozoospermia group.

Summary: Benzo(a)pyrene (BaP) is a dangerous air pollutant that can have adverse effects on human spermatozoa, including reproductive toxicity. In vitro experiments showed that BaP reduced sperm motility and migration, increased spontaneous acrosome reaction and DNA fragmentation, but had no effects on apoptotic pathways.

Summary: Maintenance of genome integrity is crucial for mammalian development in germline and preimplantation embryos. L1 retrotransposon plays an important role in germline and early embryo development in mice and humans, and its activation and expression are essential for preimplantation development. Although there have been studies on L1 expression at different stages of development, the developmental consequences of this expression remain poorly understood, and further research is needed to elucidate the relationship between L1 retrotransposition events and genomic instability during germline and early embryo development.

Summary: This study focuses on the possible relationship between telomere dysfunction and aneuploidy in human early embryo development, discussing the mechanisms of aneuploidy caused by telomere shortening and fusion in human embryos. Research suggests that telomere length plays an important role in the development of the embryo and fetus, and abnormal shortening of telomeres may lead to embryo loss during early human development. Complications of assisted reproductive technology pregnancies may also be linked to telomere shortening.

Summary: Superovulation and in vitro fertilization (IVF) may result in genomic changes, including altered telomere length and activation of retrotransposon LINE-1. This study found that embryos produced through superovulation and IVF had significantly longer telomeres compared to embryos produced naturally. The implications of this enriched telomere length for the health and lifespan of IVF offspring deserve further investigation.

Summary: Unlike other cells, sperm's telomere length increases with age. We found that as paternal age increases, telomere length increases and L1 copy number decreases significantly. Sperm with normal morphology have longer telomeres and normal and abnormal sperms have similar L1 copy numbers.

Summary: The placenta plays a crucial role in supporting the fetus during pregnancy, but it shows signs of aging in late pregnancy, including inflammation and impaired function. This pilot study discovered abnormal chromosome fusion in the placenta of full-term pregnancies. Further research is needed to determine the impact of this finding on placental function and pregnancy outcomes.
