This Program Grant investigates a number of important reproductive problems that affect the fertility of men, prostate cancer and the way the mother nurtures and protects the baby during pregnancy. The successful development of sperm requires the proper function of a number of biological processes. This grant investigates the way in which sperm are produced, the genes that are needed to control their development, and the way sperm propel themselves and fertilize the egg. The research also investigates how sperm are protected during their development from infection and immunological rejection, achieved in part by a special environment within the tubes in the testis where they grow. It appears that the general mechanisms that the body uses to combat infections are modified within the testis and the way in which this occurs may provide clues that could be applied to prevent the rejection of transplanted organs in general. Some of the substances that control these processes appear to play an important role in the body�s defense against infection. The grant also investigates the processes that are involved in the development of prostate cancer. These changes can occur over many years and the grant will study some substances that appear to be involved. The work will provide new knowledge that may assist in new tests to identify whether a cancer is slow or fast growing, thereby helping each man to decide the most sensible form of treatment. The grant will investigate how a group of proteins, that also are involved in the control of processes discussed above, assist the mother in protecting her baby during pregnancy. The outcomes will assist in the management of disturbances of pregnancy that may put the fetus at risk of survival.

该计划赠款调查了一些影响男性生育能力的重要生殖问题，前列腺癌以及母亲在怀孕期间养育和保护婴儿的方式。精子的成功发育需要一些生物过程的正常运作。该基金研究精子产生的方式，控制其发育所需的基因，以及精子推动自身和使卵子受精的方式。该研究还调查了精子在发育过程中如何受到保护，免受感染和免疫排斥，部分原因是它们生长的睾丸管内的特殊环境。看来，身体用于对抗感染的一般机制在睾丸内被修改，并且这种情况发生的方式可能提供可用于防止移植器官排斥的线索。控制这些过程的一些物质似乎在身体防御感染方面发挥着重要作用。该补助金还调查了参与前列腺癌发展的过程。这些变化可能会发生多年，赠款将研究一些似乎涉及的物质。这项工作将提供新的知识，可能有助于新的测试，以确定癌症是缓慢还是快速增长，从而帮助每个人决定最明智的治疗形式。该补助金将调查一组蛋白质，也参与控制上述过程，帮助母亲在怀孕期间保护她的婴儿。这些结果将有助于管理可能使胎儿面临生存风险的妊娠障碍。
