Environmental pollution results in serious health hazards to animals, reflected in biogenic and risk element concentrations in animal tissues. The objective of this study was to examinate concentration of selected elements in testes, and epididymal spermatozoa motility of wild boars. Wild boars were hunted in region Žuhračka - Levice, Slovak Republic. Testes were removed postmortem, spermatozoa were collected from cauda epididymis and assessed by CASA system. Elements concentrations were measured by ICP and by CV-AAS. Spermatozoa motility was 44.29% and progressive motility 18.47%. Concentration of elements in testes was in following order: K > Na > Mg > Ca > Fe > Zn > Al > Cu > Se > Mn > As > Cr > Pb > Mo > Sr > Ni > Ba > Cd > Li > Hg. The most notable correlations indicate association between Se and total spermatozoa motility, as well as with progressive motility, furthermore between As and velocity curved line and beat cross frequency. A high positive significant correlation was found between mercury and beat cross frequency. The data may serve as a fine control indicator to detect potentially toxic elements accumulated from polluted environment that can affect reproduction of wild animals.

Objective: This study aimed to evaluate the efficacy of combining levocarnitine with tadalafil in treating oligozoospermia and asthenozoospermia and to analyze its effects on serum sex hormone levels and sexual function.
Methods: A total of 80 patients diagnosed with oligozoospermia or asthenozoospermia at our hospital between March 2023 and February 2024 were randomly divided into two groups, A and B, with 40 patients each. Group A received levocarnitine combined with tadalafil, while Group B was administered levocarnitine alone.

Recent studies suggested that treating sperm with R848, a ligand for the X-linked Toll-like receptors 7 and 8 (TLR7/8) in mice, goats, and cattle, could selectively reduce the motility of X chromosome bearing sperm (X-sperm). This reduction enables the separation of X- and Y-sperm and thereby sex selection. However, through three species and multiple methods, our results challenged prior published data.

Background: Lysosomes serve not only in the degradation of cellular components but also as calcium (Ca) stores. In this study, we investigated the effects of trans-Ned19, an inhibitor of lysosomal calcium channels known to block two-pore channels (TPCs), on fertilization and oocyte activation in mice.
Methods: Pronuclear formation was assessed via Hoechst 33342 staining, cortical granule release was evaluated using agglutinin-fluorescein isothiocyanate (LCA-FITC) staining, intracellular Ca levels were monitored with Cal-520 AM, and sperm motility was analyzed using a sperm motility analysis system (SMAS).

The sterile insect technique (SIT) is a highly effective biologically-based method for the suppression of many insect pest populations. SIT efficacy could be improved by methods of male sterilization that avoid the use of irradiation that can result in diminished fitness and mating competitiveness. Alternative sterilization methods include conditional disruption of genes for male fertility, or using their sperm-specific promoters to drive the expression of genes for lethal effectors.
