In this study, we aimed to assess the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on semen parameters. The study comprised 110 sperm volunteers who self-reported SARS-CoV-2 infection from the Human Sperm Bank of the Center for Reproductive Medicine, Shandong University (Jinan, China). The volunteers had normal sperm concentration before infection. Each volunteer provided semen samples before and after infection. We selected 90 days after infection as the cutoff point. Semen parameters within 90 days after infection of 109 volunteers (group A) were compared with semen parameters before infection. Moreover, semen parameters on or after 90 days after infection of 36 volunteers (group B) were compared with semen parameters before infection. Furthermore, based on whether the volunteers had completed the three-dose SARS-CoV-2 vaccination booster, volunteers in group A and B were further divided into two subgroups separately. Semen parameters were compared before and after infection in each subgroup. Our results showed that in this cohort population, the semen quality in volunteers with normal sperm concentrations before infection decreased after SARS-CoV-2 infection within 90 days, while the semen quality returned to preinfection levels after 90 days. The completion of a three-dose SARS-CoV-2 vaccination booster may exert a protective effect on semen quality after infection.

Sperm cryopreservation is a useful storage technique in artificial insemination. Nanoparticles and nanovesicles such as exosomes are widely used in sperm cryopreservation procedures to alleviate cold-induced injury inflicted during sperm freezing. The objective of the present study was to examine the impact of varying concentrations of exosomes derived from seminal plasma added to a freezing extender on the quality of post-thawed bull sperm.

Background: Micronutrients such as vitamin B12 and D have recently gained attention for their potential roles in male reproductive health. Despite their significance, there's a critical gap in understanding their association with male infertility, particularly concerning suboptimal semen parameters. This study aimed to address this knowledge gap by examining serum vitamin B12 and D levels in infertile males, providing insights that could inform targeted interventions for couples facing male infertility challenges.

The Y chromosome contains a set of genes with testis-specific expression that are responsible for the development of testes and spermatogenesis, and it is the most important target in the search for genetic causes of male infertility. Most of these genes are located in the "azoospermia factor" AZF locus (regions AZFa, AZFb, and AZFc) on the long arm of the Y chromosome. Microdeletions of the Y chromosome, leading to the removal of the entire AZF locus as well as one or more regions (complete deletions), are one of the leading causes of spermatogenesis impairment and infertility.

Spermatozoa cryopreservation has been widely used for animal genetic conservation. Despite advances in chicken semen cryopreservation, the mechanism of spermatozoa cryodamage remains to be revealed. The cryopreservation process induces motion parameter decreased, structure damaged, proteomic and antioxidant system remodeled in spermatozoa.

This study aimed to evaluate the impact of cholesterol supplementation at various concentrations in cryopreserved Pantaneiro bovine semen on in vitro embryo production (IVEP). Grade I and II cumulus-oocyte complexes (COCs) were collected from ovaries retrieved from a commercial slaughterhouse and matured in vitro for 24 h. The matured COCs were divided into four groups based on the concentration of cholesterol -loaded cyclodextrin (CLC) during semen cryopreservation from a Pantaneiro breed bull: Control (C) - 0 mg/mL CLC, T1 - 0.
