Parental Social Environment Has no Effect on Offspring Development in the Dung Beetle: A Test of Adult Sex Ratio Effects

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We investigated whether adult sex ratio (ASR) induces transgenerational plasticity in the dung beetle Onthophagus taurus via germline transmission or behavioral parental investment. Although varying ASR treatments significantly altered parental contest and courtship behaviors, utilizing a novel egg‐transplantation protocol revealed no ASR‐induced ...

Instance of a Heteroplasmic Mitogenome in Alvinocaridid Shrimp Mirocaris fortunata (Martin & Christiansen 1995) Found at the Moytirra Deep‐Sea High‐Temperature Hydrothermal Vent Field

Ecology and Evolution, Volume 16, Issue 7, July 2026.
First complete mitochondrial genome of the deep‐sea hydrothermal vent shrimp Mirocaris fortunata (Alvinocarididae) from shotgun sequencing data on an individual tail tissue. The 15,923‐bp‐long sequence displays 98.72% pairwise identity with its closest relative, Mirocaris indica.

Semen Quality and DNA Fragmentation After Limited Testicular Sperm Extraction in Non‐Azoospermic Men With ART Failure: A Retrospective Matched Cohort Study

Health Science Reports, Volume 9, Issue 7, July 2026.
ABSTRACT Background and Aims Testicular sperm extraction (TESE) is sometimes used in non‐azoospermic men with persistent infertility, particularly in cases of high sperm DNA fragmentation index (DFI) or repeated intracytoplasmic sperm injection (ICSI) failure.

Urologic Bacteriome: The Hero or the Villain in Prostate Cancer Onset, Progression, and Treatment?

Medicinal Research Reviews, Volume 46, Issue 4, Page 1111-1151, July 2026.
ABSTRACT Prostate cancer (PCa) is the second most frequently diagnosed cancer in men worldwide and the fifth leading cause of cancer‐related mortality, presenting urgent unmet clinical needs in diagnosis and treatment. The recognition of the microbiome as a key factor in human health has prompted numerous studies, revealing an exciting new approach to ...

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development

PROTEOMICS, Volume 26, Issue 7, Page 42-56, July 2026.
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.
