The literature contains conflicting evidence regarding the existence of DNA damage in spermatozoa from infertile male patients. To examine this phenomenon, we have studied ejaculated spermatozoa from ...
Infertility is a growing problem among couples trying to conceive; in the past the female partner was singled out as the primary reason for being unable to bear a child. Research now reveals that ...
Sperm Characteristics and DNA Integrity of Iberian Red Deer（Cervus elaphus hispanicus）Epididymal Spermatozoa Frozen in the Presence of Enzymatic and Nonenzymatic Antioxidants
Cryopreservation fertilization gamete biology reproductive technology
2008/12/24
The main goal of this study was to investigate the potential protective effects of enzymatic and nonenzymatic antioxidants on cryopreservation injuries to red deer epididymal spermatozoa. In Expe...
Protamine Levels Vary Between Individual Sperm Cells of Infertile Human Males and Correlate With Viability and DNA Integrity
Spermatogenesis male fertility
2008/12/24
Sperm protamine deficiency has been associated with human male infertility. However, most studies have adopted a global approach to assessing sperm protamine levels. Thus, it is not known whether...
The objective of this study was to examine the relationship between DNA integrity and protamines in human sperm. One hundred forty-nine male infertility patients were included in an Institutional Re...
