Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

Juvenile and Pubertal Exposure to Polystyrene Nanoplastics Impairs Epididymal Structure and Sperm Quality in Mice

Environmental Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are emerging environmental contaminants capable of crossing biological barriers, accumulating in tissues, and disrupting physiological pathways. The male reproductive system is particularly vulnerable during the postnatal period, a developmental window characterized by intense testicular differentiation and epididymal ...

Effect of Propylparaben on In Vitro Maturation of Porcine Oocytes and Embryo Development

Environmental Toxicology, EarlyView.
ABSTRACT Parabens are synthetic chemicals that, due to their antibacterial and fungicidal effects, are widely used as preservatives in food, cosmetics, and personal care products, such as shampoos, hair conditioners, body creams, soaps, deodorants, makeup, wet wipes, lotions, female hygiene products, and vaginal lubricants. Several years ago, they were

Role of testicular fine‐needle aspiration in the modern male reproductive urologist′s practice

UroPrecision, EarlyView.
Abstract Background Azoospermia affects 10%–15% of infertile men, with non‐obstructive azoospermia (NOA) most often managed by microdissection testicular sperm extraction (mTESE). Despite AUA/ASRM guidelines recommending mTESE, some urologists employ testicular fine‐needle aspiration (TFNA) mapping as a diagnostic adjunct.

Prevalence of HCMV, HHV‐6, and HSV‐1/2 in the semen of men attending infertility clinics and their association with semen parameters

UroPrecision, EarlyView.
Abstract Background Viral infections have been identified as potential disruptors of male reproductive health. This study aimed to investigate the prevalence of human cytomegalovirus (HCMV), human herpesvirus 6 (HHV‐6), and herpes simplex virus types 1 and 2 (HSV‐1/2) DNA in semen samples from fertile and infertile men within the potential impact of ...

Testicular Echobiometry and Sperm Characterization in Oncilla (Leopardus tigrinus) From the Caatinga Biome

Zoo Biology, EarlyView.
We describe testicular echobiometry and sperm characterization in oncilla (Leopardus tigrinus) from the Caatinga biome, Ceará, Brazil. ABSTRACT Among neotropical small felids, the Leopardus tigrinus is classified as vulnerable by the International Union for Conservation of Nature, but studies on reproductive morphology and physiology are scarce for ...

Meloxicam and levamisole administration ameliorates FMD vaccination stress on frozen semen attributes in Sahiwal bulls

Scientific Reports
Vaccination-induced allergic reactions in bulls raise both body and testicular temperatures, leading to germ cell damage, epididymal dysfunction, accelerated testicular ageing, and increased sperm abnormalities that ultimately degrade semen quality. This

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.
