Role of Seminal Exosomes in Reproduction
Bibliographic record
Abstract
Exosomes are small lipid bilayer vesicles, ranging from 30 to 150 nm in diameter, that are secreted by various cells and facilitate intercellular communication. They originate from the endosomal system and release their contents into the extracellular environment. These nanovesicles carry bioactive molecules, including nucleic acids, lipids, and predominantly proteins, influencing target cells and contributing to cell-to-cell interactions. Exosomes play a crucial role in both normal physiological functions and pathological conditions, including male and female reproductive disorders. Various parts of the male reproductive tract release exosomes into seminal fluid. Seminal exosomes, especially epididymosomes and prostasomes, have been shown to influence male fertility. Furthermore, the role of seminal exosomes has been demonstrated in the female reproductive tract during implantation and pregnancy. Evidence shows that the exosomal cargo in seminal fluid differs between normal and pathological conditions, impacting the reproductive process. Consequently, exosomes are considered valuable biomarkers not only for diagnosis but also for potential therapeutic roles in abnormal conditions, particularly infertility. This review aims to explore the role of seminal exosomes in male fertility and their subsequent impact on the female reproductive tract during fertilization, preimplantation, implantation, postimplantation, and pregnancy-associated diseases, as well as the role of exosomes during seminal infections. Additionally, it aims to highlight the significance of seminal exosomes in medical applications and emphasize the need for future studies in this area.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
