Horse Clinical Cytogenetics: Recurrent Themes and Novel Findings

open access: yesAnimals, 2021
Clinical cytogenetic studies in horses have been ongoing for over half a century and clearly demonstrate that chromosomal disorders are among the most common non-infectious causes of decreased fertility, infertility, and congenital defects.

Analysis of Y chromosome microdeletions and CFTR gene mutations as genetic markers of infertility in Serbian men [PDF]

open access: yesVojnosanitetski Pregled, 2007
Background/Aim. Impaired fertility of a male partner is the main cause of infertility in up to one half of all infertile couples. At the genetic level, male infertility can be caused by chromosome aberrations or gene mutations.
