This document provides information about assisted reproductive technologies (ART). It defines infertility as the inability of a couple to have a baby. It describes some common ART procedures like artificial insemination, in vitro fertilization, gamete intrafallopian transfer, and intracytoplasmic sperm injection. It also discusses some ethical issues surrounding ART like risks of birth defects and what to do with leftover embryos. The document provides homework assignments related to learning about reproduction.

Chapter 6 pp. 224-230 Ch. 6.3 Assisted Reproductive Technologies
Assisted Reproductive Technologies Many people seek Assisted Reproductive Technologies (ART) if they are infertile. Infertility: the inability of a couple to have a baby Most assisted reproductive technologies involve: 1) Removing eggs from the woman 2) Fertilizing the eggs 3) Returning the fertilized eggs to the uterus.
Types of Assisted Reproductive Technologies Artificial Insemination (AI): a reproductive technology that includes collecting sperm from a male and injecting into a female AI is widely used to breed farm animals , especially dairy cattle
Types of Assisted Reproductive Technologies In Vitro Fertilization (IVF): technology used to treat specific fertility problems by fertilizing an egg cell in a petri dish in vitro means in glass In IVF, egg and sperm are collected and fertilization takes place in a dish . Embryo(s) are then placed in the females uterus.
Video In Vitro Fertilization
Types of Assisted Reproductive Technologies Gamete Intrafallopian Transfer (GIFT): an assisted reproductive technology in which eggs and sperm are collected, mixed, then injected into the womans fallopian tubes. Fertilization takes place inside the womans body Intracytoplasmic Sperm Injection (ICSI): a specialized procedure in which a single sperm cell is injected into an egg cell. The zygote is then inserted into the womans uterus. ICSI has a 25% success rate.
The Impact of Assisted Reproductive Technologies on Society Reproductive technologies can help childless couples, but may carry a higher risk of birth defects. Q: Should we continue to use a technology that carries an extra risk? Often ARTs result in leftover embryos. Q: What should be done with them? Most children conceived by AI will never know the identity of their fathers. Q: Is it fair to a child to keep this information secret?
