Automated Sperm Morphology Analysis Based on Instance-Aware Part Segmentation [PDF]

arXiv
Traditional sperm morphology analysis is based on tedious manual annotation. Automated morphology analysis of a high number of sperm requires accurate segmentation of each sperm part and quantitative morphology evaluation. State-of-the-art instance-aware part segmentation networks follow a "detect-then-segment" paradigm.

Isolated asthenozoospermia: What should we know? A narrative review of literature

UroPrecision, EarlyView.
ABSTRACT Male infertility contributes to 20%–70% of infertile couple cases worldwide. One of the key challenges in this area is asthenozoospermia or reduced sperm motility. A particular subset, known as isolated asthenozoospermia (iASZ), in which low motility occurs without abnormalities in sperm count or shape, often goes unnoticed and is not well ...

Systematic review and meta‐analysis of COVID‐19 association with human semen quality: Changes in semen parameters pre‐ and post‐COVID

UroPrecision, EarlyView.
Abstract Coronavirus disease (COVID‐19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), which may infect the cells through binding with the angiotensin‐converting enzyme 2 (ACE2) receptors that can also be found in the male reproductive organs.

From clinical observations to molecular insights: Decoding immune checkpoint inhibitors‐induced prostatitis

VIEW, EarlyView.
Immune checkpoint inhibitors (ICIs), an innovative class of cancer therapeutics, may elevate the risk of prostate inflammation (prostatitis) in a subset of male patients. Our investigation demonstrated that ICIs can induce inflammatory responses in prostate tissue; however, selectively targeting specific inflammatory pathways may potentially mitigate ...

Glycopattern comparison of sperm and exosomes from conventional in vitro fertilization and rescue intracytoplasmic sperm injection: Enhancing sperm motility through exosome‐mediated glycan modulation

VIEW, EarlyView.
Infertility is a global concern, with male factors contributing to nearly half of cases. This study compared glycopatterns of sperm and sperm‐derived exosomes from conventional IVF and rescue ICSI (RICSI) patients, revealing key differences in glycan expression.
