O’Donnell said much research still needs to be done to support the sick-man model and test whether males are much less resistant to disease than females. ‘We hope our research will inspire researchers to these ideas. Researchers need to challenge different species of sociable bugs with disease pathogens to find whether men and women differ in disease level of resistance,’ he said. ‘Our knowledge of the genetic basis of disease resistance is definitely pretty weak, medically even. There happens to be little evidence showing how genetic variability at the average person level is effective in overcoming disease, even though this is often assumed to be the case by biologists.The types of abortion process performed during second trimester include: Dilation and Curettage referred to as suction curettage or vacuum aspiration Also, this medical procedure terminates pregnancy as high as 16 weeks gestation.
