Sigma Theta Tau International Alpha Lambda Chapter Understanding Fertility Decisions in the 21st Century: The Use of Emerging Technologies in Reproduction And Genetics Patricia E. Hershberger, PhD, APRN, BC University of Illinois at Chicago Assistant Professor College of Nursing March 6, 2009 “Infertility” The simple union of man and wife In love creates a brand new life. A child to cherish, play with and be Their link with immortality. What bliss and joy they anticipate Unless infertility becomes their fate. And buries dreams that die within As they mourn their child who might have been. --- Mache Seibel, MD Definitions Fertility is… The ability of a man and a woman to reproduce Infertility is… A lack of fertility Involuntary childlessness A reduction in the ability to establish pregnancy or to carry a baby to term Commonly known as the “inability to conceive after one year of unprotected intercourse” Sterility is… The absolute inability to reproduce Incidence of Infertility In the U.S. about 10-15% of the 62 million women of reproductive age in 2002 had difficulty getting pregnant or carrying a baby to term. About 1.2 million of these women (or 2%) sought medical care for infertility. Infertility increases with age. Maximum fertility is at age 15-24 years.

Based on the underlying reason for using PGD Study III Fertility Preservation Study III Fertility Preservation Purpose Describe the Decision Making Processes of about 30 Women, age 18 to 43 years, who are Facing a Life Threatening Illness and are choosing to either Accept or Decline Fertility Preservation Treatment (i.e., oocyte, embryo, ovarian cryopreservation) Design Qualitative, Naturalistic Recruitment & Data Collection Large Urban Infertility Clinic, Support Groups & Internet Face-to-Face, Telephone, & E-mail Interviews • How do emerging technologies in reproduction and genetics/genomics shape the lives of women and couples? Society? • How can nurses, advanced practice nurses, and nurse scholars improve patient decision making within repro- genomics? • What are the influences and responsibilities of health care providers, society, and policymakers within repro- genomics?
