Study on Influencing Factors of Semen Quality in Fertile Men

Frontiers in Physiology, 2022
ObjectiveTo establish a system for evaluation of semen quality in fertile men by factor analysis (FA).MethodsThe FA method was used to analyze five sperm test indicators for fertile men (sperm pH, sperm motility, sperm progressive motility, semen density,

Automatic classification of the acrosome status of boar spermatozoa using digital image processing and LVQ [PDF]

, 2006
We consider images of boar spermatozoa obtained with an optical phase-contrast microscope. Our goal is to automatically classify single sperm cells as acrosome-intact (class 1) or acrosome-damaged (class 2).

Scriptaid is a prospective agent for improving human asthenozoospermic sample quality and fertilization rate in vitro

Asian Journal of Andrology
Male infertility is a global issue caused by poor sperm quality, particularly motility. Enhancement of the sperm quality may improve the fertilization rate in assisted reproductive technology (ART) treatment.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Sperm quality before treatment in patients with early stage Hodgkin’s lymphoma enrolled in EORTC-GELA Lymphoma Group trials

Haematologica, 2009
Background Although widely recommended, cryopreservation of sperm is sometimes not performed for patients with Hodgkin’s lymphoma because of presumed poor sperm quality related to the disease.

Microneedles Mediated Delivery of Nanodiamonds for Quantum Sensing of Free Radicals in Skin Tissue

Advanced Materials Technologies, EarlyView.
Fluorescent nanodiamonds are nanoscale sensors capable of monitoring cellular stress responses. However, to function effectively, they must be delivered into cells or tissues. Here, we demonstrate their application in the skin by developing a dissolvable microneedle platform that dissolves after skin insertion, enabling the delivery of nanodiamonds ...
