The efficiency of conventional microscopic selection is comparable to the hyaluronic acid binding method in selecting spermatozoa for male infertility patients

Taiwanese Journal of Obstetrics & Gynecology, 2015
Objective: To evaluate if hyaluronic acid (HA)-bound spermatozoa surpassed conventional microscopy-selected spermatozoa in the status of sperm DNA integrity by acridine orange (AO) fluorescence staining.

Assessment of Gold‐Mediated Male Reproductive Dysfunction in Male WISTAR Rats Through Sperm Analysis and Testosterone Measurement

Journal of Applied Toxicology, EarlyView.
ABSTRACT Gold has been used for centuries in both ornamental and medicinal contexts. More recently, gold compounds, containing ions or nanoparticles, have attracted attention for their anti‐inflammatory, anticancer, and diagnostic applications. Therefore, concerns about systemic toxicity and biodistribution have prompted investigations into the ...

Redox‐Associated Renal and Male Reproductive Alterations Following Dexamethasone Exposure in Male Rats: Histopathological and Spermatological Evaluations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Dexamethasone (DEX) is widely used in clinical practice, although it may also cause oxidative stress–related damage in different tissues, including the kidney and male reproductive system. This study investigated DEX‐induced renal and reproductive injury in rats and evaluated the modulatory effect of reduced glutathione on DEX‐associated redox

A review of sperm cryopreservation in the domestic dog and cat—part II, freezing epididymal spermatozoa, why is it different from ejaculated spermatozoa?

Acta Veterinaria Scandinavica
If a male dies suddenly or requires castration, it may still be possible to produce offspring through artificial insemination (AI) by cryopreserving spermatozoa retrieved from the epididymis.

Identification and Discrimination of Sulfated and Unsulfated Gut‐Hormone Biomarkers in Human Serum by Nanopore

Small, EarlyView.
This study discriminates between sulfated and unsulfated cholecystokinin‐8 gut‐hormone forms at single‐molecule‐level resolution. Using an aerolysin nanopore embedded in a hybrid lipid‐polymer membrane, the system produces distinct electrical signatures enabling highly sensitive detection, even in 20% human serum.

IN VITRO FERTILITY TEST OF HUMAN SPERMATOZOA MEMBRANE PROTEIN FERTILIN BETA ANTIBODY IN MICE (Mus musculus Balb/c) AS IMMUNOCONTRACEPTIVE CANDIDATE

Folia Medica Indonesiana, 2017
One of the materials as potential candidates immunocontraception material is spermatozoa. Fertilin beta is spermatozoa membrane protein and is found only in mature spermatozoa and ejaculate, which serves as an adhesion molecule.

Chrysin Mitigates Acetamiprid‐Induced Testicular Injury in Mice via Suppression of Endoplasmic Reticulum Stress and Inflammation

Environmental Toxicology, EarlyView.
ABSTRACT Acetamiprid (ACP) is a neonicotinoid pesticide that is extensively utilized for the management of insect populations, but its toxic effects on the male reproductive system have become a source of concern. Chrysin (CHR) is a natural flavone found in many plants and bee products, including honey and propolis.

Storage and release of spermatozoa from the pre-uterine tube reservoir.

PLoS ONE, 2013
In mammals, after coitus a small number of spermatozoa enter the uterine tube and following attachment to uterine tube epithelium are arrested in a non-capacitated state until peri-ovulatory signalling induces their detachment.
