Untargeted metabolomics fingerprints in seminal plasma of patients with abnormal sperm morphology using high-performance liquid chromatography and mass spectrometry [PDF]

Frontiers in Molecular Biosciences
Teratozoospermia, a qualitative sperm disorder characterized by abnormal sperm morphology, represents one of the causes of male infertility worldwide. The metabolic analysis of human seminal plasma (SP), can provide insights into the underlying molecular

Is sperm telomere length altered in teratozoospermia specimens? A case-control study [PDF]

International Journal of Reproductive BioMedicine, 2022
Background: Male factor infertility is a multifactorial defect, and many of its etiologies are unknown. Teratozoospermia is determined by the existence of over 85% morphologically abnormal spermatozoa in semen which are almost incompetent in ...

SEPTIN12 Genetic Variants Confer Susceptibility to Teratozoospermia [PDF]

PLoS ONE, 2012
It is estimated that 10-15% of couples are infertile and male factors account for about half of these cases. With the advent of intracytoplasmic sperm injection (ICSI), many infertile men have been able to father offspring. However, teratozoospermia still remains a big challenge to tackle. Septins belong to a family of cytoskeletal proteins with GTPase

Impact of isolated teratozoospermia on the outcome of intrauterine insemination [PDF]

Fertility and Sterility, 2005
One thousand six hundred forty-one IUI cycles performed in 615 couples were categorized, depending on the semen analysis of the male partner, in three groups of: normozoospermia, teratozoospermia, and male factor infertility. Clinical pregnancies and live births per cycle were significantly decreased in the teratozoospermia group when compared to the ...

Recommendations for Human Sperm Morphology Assessment in 2025: An Expert Review From the French BLEFCO Group. [PDF]

Andrology
ABSTRACT Background Numerous publications have questioned the lack of analytical reliability and clinical relevance of sperm morphology assessment for infertility workup and before use of assisted reproductive techniques (ART). There is a huge variability in the performance and interpretation of this test.

Sperm metabolomic signatures of asthenozoospermia and teratozoospermia in Chinese reproductive-age men [PDF]

Scientific Reports
Asthenozoospermia and teratozoospermia are common causes of male infertility. Despite their prevalence, the underlying metabolic mechanisms remain poorly understood.

Teratozoospermia and Embryo Development: The Significance of Sperm Selection in In Vitro Fertilization Success. [PDF]

J Clin Med
Background: Sperm morphology is a key factor influencing fertilization and embryo development in assisted reproductive technology (ART). However, the predictive value of sperm deformity indices and selection techniques remains debated.

Isolated teratozoospermia: a cause of male sterility in the era oF ICSI? [PDF]

Frontiers in Bioscience, 2007
Single structural defects involving the totality of ejaculated sperm are among rare cases of untreatable human male infertility. This form of infertility is of genetic origin and is generally transmitted as an autosomal recessive traits. Acrosome agenesis or globozoospermia results from perturbed expression of nuclear proteins or from an altered Golgi ...
