Scientists to examine the effects of cancer drugs on male reproduction
February 27, 2003
There is a very real concern about the potential impact of exposure to drugs or environmental chemicals on reproduction in general and germ cells in particular. The thought pattern is that drug combinations used to treat testicular cancer and lymphomas have significant detrimental effects on the quantity and quality of male germ cells.
Furthermore, damage to these germ cells may lead to fetal death and birth defects in the offspring or to an increased risk of transmitting genomic damage to future generations.
Aided by a $2.4 million, five-year grant from the Canadian Institutes of Health Research, researchers from 看片视频 University's Faculty of Medicine, the 看片视频 University Health Centre, the Sir Mortimer B. Davis Jewish General Hospital, in conjunction with researchers from the University of Calgary, the University of Ottawa and the Universit茅 de Montr茅al, will tackle the issue in three phases. In Project 1, they will evaluate the effects of anticancer drug treatments in men of reproductive age on their fertility and the genetic integrity of their germs cells. Project 2 will determine what risk information is provided to these men and if the provision of this information in a timely and supportive manner will reduce their psychosocial stress. In Project 3, animal models will be used to determine how cancer treatments damage male germ cells, somatic cells or stem cells in the testis. The goal of the third phase will be to establish endpoints that could be used as markers and will be useful in assessing human germ cell quality.
This important study, led by main Investigator Dr Bernard Robaire, Professor of Pharmacology and Therapeutics and of Obstetrics and Gynecology at 看片视频 University and involving 14 researchers from a variety of fields including Pharmacology, Urology, Psychology, Oncology, Genetics, Pediatrics, Teratology, and Epidemiology, is part of a Strategic Initiative of the CIHR's Institute of Human Development and Child and Youth Health aimed at improving sperm, egg and embryos to better treat infertility. The 看片视频 Project is one of the three funded across Canada.
"The information generated from these Projects will allow the establishment of recommendations to modify the current clinical guidelines in managing cancer patients with respect to the needs and timing of gamete cryopreservation," explained Lead Investigator Dr Bernard Robaire. "Furthermore, data from these studies will allow improve the quality of genetic and fertility counseling for couples. Finally, these projects will provide a unique framework for the training of future generations of researchers in the multi-disciplinary approach crucial to this field," concluded Dr Robaire.
"看片视频's Faculty of Medicine has a rich history of almost 200 years of experience and a worldwide reputation for accomplishments in research. The study of reproductive health is of paramount importance to us and this is an important step in this area of research," says Dr Abraham Fuks, Dean of the 看片视频 University Faculty of Medicine.
看片视频 University's Faculty of Medicine's 600 medical and nursing students as well as interns from the allied health professions and 800 residents and fellows train in a number of affiliated hospitals.
The 看片视频 University Health Centre (MUHC) receives over a million patient visits each year, including some 40,000 in-patient stays. The Research Institute of the MUHC has over 500 researchers and some 650 graduate and post-graduate doctoral students. It is the largest research institute of its kind in Canada.
