Paternal factors contributing to embryo quality [PDF]
Journal of Assisted Reproduction and Genetics, 2018 Advancing maternal and paternal age leads to a decrease in fertility, and hence, many infertile couples opt for assisted reproductive technologies [ART] to achieve biological parenthood. One of the key determinants of achieving a live outcome of ART, embryo quality, depends on both the quality of the oocyte and sperm that have created the embryo ...

Epigenetics, embryo quality and developmental potential [PDF]
Reproduction, Fertility and Development, 2014 It is very important for embryologists to understand how parental inherited genomes are reprogrammed after fertilisation in order to obtain good-quality embryos that will sustain further development. In mammals, it is now well established that important epigenetic modifications occur after fertilisation.
