Apoptosis in human unfertilized oocytes after Intracytoplasmic Sperm Injection [PDF]

open access: yes, 2005
Objective To investigate the presence of programmed cell death in unfertilized oocytes after intracytoplasmic sperm injection (ICSI), assuming that previous apoptotic events could be correlated with the fertilization failure.

Associations of sperm DNA fragmentation with lifestyle factors and semen parameters of Saudi men and its impact on ICSI outcome

open access: yesReproductive Biology and Endocrinology, 2018
Background Male factor infertility is quite common as 30–50% of infertility cases are due to sperm defects. The high sperm DNA fragmentation is one of the causes of male factor infertility.

Petal Senescence: New Concepts for Ageing Cells [PDF]

open access: yes, 2009
Senescence in flower petals can be regarded as a form of programmed cell death (PCD), being a process where cells or tissues are broken down in an orderly and predictable manner, whereby nutrients are re-used by other cells, tissues or plant parts.
