Complete the following paragraph to describe the technologies available to help infertile couples conceive. During a process called artificial insemination, sperm from a partner or donor is inserted into a woman's vagina. This is especially useful when the male partner's sperm count is low. Sometimes, drugs are given to a woman to stimulate her ovaries to ovulate, then sperm are placed directly into the uterus, a process called . Once takes place, the resulting embryo is transferred to the woman's uterus, where, hopefully, implantation occurs. During , immature oocytes are removed from a woman's ovaries and fertilized in a petri dish with sperm. A process called is similar to the above process in that the oocyte is removed from the ovaries and incubated with sperm. However, as soon as they have been brought together, they are returned to the . Occasionally, when the male partner has severe infertility problems, it is possible to inject a single sperm into an oocyte and place the resulting embryo within a woman's uterus. This process is called . When the female partner has severe infertility problems or is unable to carry a fetus to term, can be used. This is where a contracted woman carries the resulting embryo to term and delivers the baby for the contracting parents.

Increasing the chance of conception Complete the following statements on assisted reproductive technologies and how they can increase the chances of conceiving a child when dealing with infertility. Not all choices will be used. When facing infertility, conception is ________ if assisted reproductive technologies are used. These techniques carry out the fertilization process in a lab or clinic. A physician places sperm into the vagina in an assisted reproductive process called ________. This process can be conducted using donor sperm, a partner's ________ sperm if low sperm count has been an issue, or a combination of both. Immature eggs are harvested and brought to maturity in laboratory glassware during ________. Mature eggs are introduced to concentrated sperm and resulting ________ are transferred to the uterus during the secretory phase of her uterine cycle. A woman who is having trouble getting pregnant or faces serious health risks if she becomes pregnant, among other reasons, might contract and pay a ________ mother to carry a baby for her. The child can be, but does not have to be, a couple's biological child. The success rate of IVF is relatively low. To overcome this issue, a process called ________ was devised. This process usually involves placing the eggs and sperm in the ________ instead of the uterus.

Many infertile couples turn to in vitro fertilization to try to have a baby. In this technique, sperm and ova are collected and used to create eight-cell embryos for implantation into a woman’s uterus. At the eight-cell stage, one of the fetal cells can be removed without causing harm to the developing fetus. Once removed, the cell can be genetically tested. Some couples may know that a particular genetic disease runs in their family. They might wish to avoid implanting any embryos with the disease-causing genes. Do you think this is an acceptable use of genetic testing? What if a couple wanted to use genetic testing to select embryos for traits unrelated to disease, such as freckles? Do you think that couples undergoing in vitro fertilization should be allowed to perform whatever genetic tests they wish? Or do you think that there should be limits on what tests can be performed? How do you draw the line between genetic tests that are acceptable and those that are not?
