Sperm Morphology of Post-wash Sample and Its Association with Clinical Pregnancy among the Couples Undergoing Intrauterine Insemination: A Cohort Study [PDF]

Journal of Human Reproductive Sciences
Background: Intrauterine insemination (IUI) is an effective and inexpensive method of managing patients with unexplained and male factor infertility. It is attempted before proceeding to more invasive assisted reproductive techniques such as in vitro ...

Impaired semen quality, an increase of sperm morphological defects and DNA fragmentation associated with environmental pollution in urban population of young men from Western Siberia, Russia.

PLoS ONE, 2021
Poor sperm morphology and an elevated DNA fragmentation level are considered to be related to spermiogenesis malfunctions as a result of genetic mutations and effects of environmental factors, including industrial pollution.

The Role of Sperm Morphology Standards in the Laboratory Assessment of Bull Fertility in Australia

Frontiers in Veterinary Science, 2021
The lack of standardization in the laboratory assessment of semen questions the reliability of semen analysis, and makes meaningful interpretation of these evaluations impossible.

SpermTree, a species-level database of sperm morphology spanning the animal tree of life

Scientific Data, 2022
Sperm are the most morphologically variable cell type known, despite performing the same functional role of fertilizing eggs across all sexually reproducing species. Sperm morphology commonly varies among individuals, populations, closely related species,

Sperm Morphology Assessment in the Era of Intracytoplasmic Sperm Injection: Reliable Results Require Focus on Standardization, Quality Control, and Training

The World Journal of Men's Health, 2021
Semen analysis is the first, and frequently, the only step in the evaluation of male fertility. Although the laboratory procedures are conducted according to the World Health Organization (WHO) guidelines, semen analysis and especially sperm morphology ...

Longer Sperm Swim More Slowly in the Canary Islands Chiffchaff

Cells, 2021
Sperm swimming performance affects male fertilization success, particularly in species with high sperm competition. Understanding how sperm morphology impacts swimming performance is therefore important.

Abnormal Human Sperm Parameters Contribute to Sperm DNA Fragmentation in Men with Varicocele [PDF]

The World Journal of Men's Health, 2018
Purpose: This study was performed to evaluate and compare threshold sperm parameters and sperm DNA fragmentation index (DFI), and further analyzed whether sperm DFI could be predicted from sperm parameters in men with varicocele.
