Anatomy 14. A surgical technique, called a tubal ligation, ties the Fallopian tubes as a method of female sterilization. (a) Why would a woman who has undergone this procedure be unable to get pregnant? Explain your answer. (b) The Pomeroy procedure for tubal ligation can be reversed. Approximately 60 % of the women who have had the procedure reversed become pregnant. Conduct research to learn more about the Pomeroy procedure and its reversal. Pomeroy

Page 30 Web Activity: Creating a Database of Sexually Transmitted Diseases Worldwide, sexually transmitted diseases (STDs) find more than 250 million hosts each year. STDs are easily spread through any person-to-person transfer of bodily fluids such as semen, vaginal secretions, or blood. If left untreated, some STDs can cause inflammation and scarring of reproductive passages, leading to infertility. STDs can also result in other serious health problems. The database you will create in this Web Activity will help people find information about STDs. Follow this link to the Web Activity The links below will help you to begin your research. You should also look for other sources. Alberta Government Health and Wellness Public Health Agency of Canada The Center for Disease Control

Page 38 Canadian Achiever: Dr. Renée Martin Pregnancy loss, birth defects, and mental retardation have been linked with chromosome abnormalities in sperm and eggs, but much of the scientific research to date has focused on abnormalities in the egg. Dr. Renée Martin, a medical geneticist from the University of Calgary, is recognized for her research on chromosomal abnormalities in human sperm cells. A Research Centre at the University has been named after her. Dr. Martin's research indicates that the sperm for normal men has a frequency of 10 % chromosomal abnormality, but men who have undergone radiotherapy have much higher frequencies of abnormal sperm. One of the most important questions to be answered is whether or not any of these abnormal sperm cells actually fertilize an egg. Dr. Martin's research will provide valuable information on birth defects and miscarriages. Visit the Nelson Web site to learn more about Dr. Martin's research contributions.

Page 41 Section 19.3 Questions 6. Thalidomide caused birth defects in the late 1950s and early 1960s. (a) Refer to the Nelson Science Web site to discover why thalidomide was given to pregnant women. (b) Was the testing conducted on thalidomide adequate? Explain why or why not. (c) How is the ability of the drug to block the growth and development of blood vessels being exploited by scientists seeking a way to control cancerous tumours? (d) Thalidomide blocks the action of tumour necrosis factor (TNF) alpha, a protein that causes inflammation, fever, weight loss, and many other problems. Research the ways that thalidomide might be used to treat diseases that have elevated levels of TNF alpha, such as tuberculosis, lupus, AIDS, and leprosy. Thalidomide
Victims Association of Canada 10. In Alberta, the number of teenage pregnancies has been described as alarming. Two very different solutions have been proposed by groups to address this concern. Visit the Nelson Web site for research information to assist you in answering the following questions. (a) Information on abstinence and support for teens practicing abstinence has been suggested as the best possible solution to the issue. Research why some groups advocate this solution. (b) Other groups propose harm reduction strategies that provide teens with information on contraceptives. Survey different methods of contraception and assess the effectiveness of each methodology. (c) Construct a chart that compares the advantages provided by abstinence and contraception. Which personal values would make one solution preferable to another? Teen

Page 51 Unit 30B Review To alleviate the symptoms of menopause, many women turn to hormone replacement therapy (HRT). Although estrogen-the main hormone in HRT-reduces "hot flashes," prevents bone loss, and may even improve memory, it raises the risk of blood clots and ovarian and breast cancer. Using the Internet and other resources, investigate and write a brief report on what is being done to meet the demand for HRT without subjecting women to its risks. Include some lifestyle changes that might help in the management of menopause. Health
