Approximately five million American couples cannot conceive children. For those who do conceive, some women experience difficulty carrying the child to term. As a result, more than fifteen percent of all American women have received some form of fertility treatment. Although knowledge and technology in this area is rapidly advancing, there is still a lack of basic, comprehensive information about fertility and infertility written for the general reader. This new addition to the Facts On File Library of Health and Living series addresses that need with a guided tour through the reproductive system. The Encyclopedia of Fertility and Infertility covers key aspects of this growing health concern, including causes and remedies, treatment options, and the latest advances in the field and in birth control. Extensive appendixes list major organizations and resources related to fertility and infertility; major periodicals, journals and web sites offering further information on the topic; and tips on selecting a fertility clinic. Also featured is an extensive bibliography and a glossary of medical terms to promote further research. More than 600 entries cover: Amenorrhea; Chemicals and infertility; Donor insemination; Endometriosis; Fibroids and infertility; Hormone replacement therapy; Impotence; Miscarriage; Ovarian cancer and fertility drugs; Pap smear; Sperm bank; Ultrasound.
