Comparison of different chromatin staining techniques for bull sperm

Comparison of different chromatin staining techniques for bull sperm

Morphological analysis of semen is a very important step in fertility assessment, but many semen defects are not detectable at the morphological level. These include pathological changes in sperm chromatin structure. During mammalian spermiogenesis, histone proteins associated with DNA structure are replaced by specific protamines, with which chromatin does not form nucleosomal complexes. In th...

Comparison of Different Sperm Selection Techniques in Ram Frozen - Thawed Sperm

Background: The success of fertilization is directly associated with semen quality and the sperm preparation. Considering the common use of cryopreserved spermatozoa, there is a need to develop strategies for sperm preparation in order to achieve a sperm sample of high quality through a rigorous selection of sperm. Thus, sperm cells are being more extensively investigate. This study aimed evalu...

Etiology and Evaluation of Sperm Chromatin Anomalies

Evidence suggests that human sperm chromatin anomalies adversely affect reproductive outcomes and infertile men possess substantially amount of sperm with chromatin anomalies than fertile men. Routine semen analysis evaluates parameters such as sperm motility and morphology, but does not examine the nuclear DNA integrity of spermatozoa. It has been suggested that altered nuclear chromatin struc...
