In mammalian oocytes DNA damage can cause chromosomal abnormalities that potentially lead to infertility and developmental disorders. However, there is little known about the response of oocytes to DNA damage. Here we find that oocytes with DNA damage arrest at metaphase of the first meiosis (MI). The MI arrest is induced by the spindle assembly checkpoint (SAC) because inhibiting the SAC overr...

Recently, several studies suggested that BPA has destructive effects on DNA and chromosomes in normal body cells via estrogen receptors (ER). Therefore, BPA could be considered as an important mediator in many diseases such as cancer. However, there are still many controversial issues which need clarification...
in this study, chromosome analyses were performed on 70 infertile azoospermic and oligospermic (<20 million/ml) men, and also cultures of peripheral blood lymphocytes by high resolution banding method were analysed as well. it is revealed 8 (11.43 percent) men with chromosomal abnormality. there were 31.4 percent patients with azoospermia and 68.6 percent with oligospermia from several thousand...
