CCDC189 depletion leads to oligo-astheno-teratozoospermia and male infertility in mice
Biology of ReproductionIn male reproductive system, proteins containing the coiled-coil domain (CCDC) are predominantly expressed in specific regions including the testis, epididymis, seminal vesicle, and prostate.

[Molecular genetic mechanisms of teratozoospermia].
Zhonghua nan ke xue = National journal of andrology, 2014Teratozoospermia is one of the important factors contributing to male infertility, and its pathogenesis is not yet clear. Recent years have witnessed some progress in the researches on sperm morphology, and some genes have been confirmed to be correlated with spermatogenesis.

Journal of Trace Elements in Medicine and Biology
BACKGROUND Oligo-astheno-teratozoospermia (OAT), a leading cause of male infertility, affects approximately 30 % of reproductive-aged men. While trace elements influence semen quality, prior investigations predominantly focused on single-element effects.

Oxidative stress and phenotype frequencies of paraoxonase‐1 in teratozoospermia
Andrologia, 2019Oxidative stress causes infertility in men by affecting especially sperm morphology. The aim of the study was to examine the frequencies of paraoxonase-1 (PON1) phenotypes and the serum PON1, arylesterase, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index, catalase and thiol levels in teratozoospermic infertile men and ...

[Teratozoospermia affects in vitro fertilization outcome].
Zhonghua nan ke xue = National journal of andrology, 2009To analyze the possible causes of total fertilization failure (TFF) in conventional in vitro fertilization (IVF).We included in this study 552 couples who accomplished the first conventional IVF cycle in our center from January 2007 to August 2008. All the males met the Kruger/Tygerberg criteria, with the teratozoospermia rate < 96% in the previous 12 ...

[Association of PRM1-190C- > A polymorphism with teratozoospermia].
Zhonghua nan ke xue = National journal of andrology, 2013To investigate the association of single nucleotide polymorphism (SNP) of the Protamine 1 (PRM1) gene in infertile men with teratozoospermia.We collected semen samples from 157 infertile men with teratozoospermia (case group) and 37 age-matched male volunteers (control group), and subjected them to morphological analysis.

[400 cycles with assisted fertilization in severe teratozoospermia].
Geburtshilfe und Frauenheilkunde, 1995From May 1991 to July 1993, assisted fertilisation by micromanipulation (PZD, SUZI and ICSI) was performed in 397 cycles with severe teratozoospermia. In the second series of 152 cycles with SUZI, the pregnancy rate per cycle was 5% (10% per transfer). In the third series, the method was changed from SUZI to ICSI.
