Mutations in CCIN cause teratozoospermia and male infertility

Science Bulletin, 2022
Teratozoospermia is usually associated with defective spermiogenesis and is a disorder with considerable genetic heterogeneity. Although previous studies have identified several teratozoospermia-associated genes, the etiology remains unknown for a majority of affected men.

Molecular genetic mechanisms of teratozoospermia

Zygote, 2023
SummaryIn recent years, the incidence of teratospermia has been increasing, and it has become a very important factor leading to male infertility. The research on the molecular mechanism of teratospermia is also progressing rapidly. This article briefly summarizes the clinical incidence of teratozoospermia, and makes a retrospective summary of related ...

Genetic aspects of monomorphic teratozoospermia: a review [PDF]

Journal of Assisted Reproduction and Genetics, 2015
Teratozoospermia is characterized by the presence of spermatozoa with abnormal morphology over 85 % in sperm. When all the spermatozoa display a unique abnormality, teratozoospermia is said to be monomorphic. Two forms of monomorphic teratozoospermia, representing less than 1 % of male infertility, are recognized: macrozoospermia (also called ...
