Background
General obesity classified by body mass index has been linked to a reduction in semen quality; however, evidence on the adverse effect of central obesity on semen quality remains limited.
Objectives
To investigate the association between central obesity and semen quality.
Materials and methods
We conducted a cross‐sectional study of 4513 sperm donation volunteers in Guangdong Provincial...
Background
Previous studies have reported lower semen quality in malignant neoplasm patients before antineoplastic treatments, but the adverse effects of malignant neoplasms on semen quality have rarely been quantitatively evaluated. In addition, due to the lack of a comparable control group and limited types of studied malignant neoplasms, the results remain inconsistent and inconclusive.
Objectives...
Recently airflow sensors based on mechanical deformation mechanisms have drawn extensive attention due to their favorable flexibility and sensitivity. However, the fabrication of highly sensitive and self‐adaptive airflow sensors in a simple, controllable, and scalable method still remains a challenge. Herein, inspired by the wing membrane of a bat, a highly sensitive and adaptive graphene/single‐walled...
