"The embryos generated were subsequently transplanted into surrogates." "The basic idea was that we would collect eggs from the good mothers and put them together with the semen from the best bulls from around the world." "This long term interest stems from early childhood experiences in which my family were using ARTs to improve the quality of our herd of beef and dairy cattle," the Gloucester native recalls. Spanning the life sciences and medicine fields, Brett's efforts are also concentrated on improving artificial reproductive technologies (ARTs). "They may hold a key role in helping to define the underlying cause of male infertility." "I specifically look for the proteins that are missing or appear to be behaving abnormally," he explains. Structure, function and interactions of proteins that differ between the two. Comparing and contrasting samples of sperm that are able to bind to eggs with samples of sperm that can't, the proteomics expert is working to get a grasp on the Though there are "countless things" that can go wrong during the process of fertilisation, Brett is opting to focus mainly on its beginning. "Physiological insights provided by studying these cells can help us augment the success of captive breeding too." "If we can understand the cellular defects present in the sperm of infertile males, then we may be able to develop methods to replicate them in pest animal species to create a new form of contraceptive." Male factor infertility, contraception and the conservation of endangered animals. The esteemed educator and innovator studies all four seemingly disparate populations in his research, shedding light on the surprising connections between What do adult humans, wild rabbits, platypus and Australian saltwater crocodiles have in common? Plenty, according to Professor Brett Nixon. Of sperm dysfunction from multiple, linked perspectives. Of indomitable spirit, Professor Brett Nixon is pursuing the mysteries
