The Relationship Between Sperm Morphology and Chromatin Integrity in the Koala（Phascolarctos cinereus）as Assessed by the Sperm Chromatin Dispersion Test（SCDt）
DNA damage marsupial
2008/12/24
Koala (Phascolarctos cinereus) sperm nuclei show a tendency to swell after cryopreservation, but it is uncertain whether this phenomenon is associated with DNA fragmentation. In this study, we va...
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 ...
