SurrogacySurrogacy is an arrangement, often supported by a legal agreement, whereby a woman agrees to delivery/labour on behalf of another couple or person, who will become the child's parent(s) after birth. People may seek a surrogacy arrangement when a couple do not wish to carry a pregnancy themselves, when pregnancy is medically impossible, when pregnancy risks are dangerous for the intended mother, or when a single man or a same sex couple wish to have a child. In surrogacy arrangements, monetary compensation may or may not be involved.
Preimplantation genetic diagnosisPreimplantation genetic diagnosis (PGD or PIGD) is the genetic profiling of embryos prior to implantation (as a form of embryo profiling), and sometimes even of oocytes prior to fertilization. PGD is considered in a similar fashion to prenatal diagnosis. When used to screen for a specific genetic disease, its main advantage is that it avoids selective abortion, as the method makes it highly likely that the baby will be free of the disease under consideration.
Assisted reproductive technologyAssisted reproductive technology (ART) includes medical procedures used primarily to address infertility. This subject involves procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), cryopreservation of gametes or embryos, and/or the use of fertility medication. When used to address infertility, ART may also be referred to as fertility treatment. ART mainly belongs to the field of reproductive endocrinology and infertility.
In vitro fertilisationIn vitro fertilisation (IVF) is a process of fertilisation where an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from her ovaries and letting sperm fertilise them in a culture medium in a laboratory. After the fertilised egg (zygote) undergoes embryo culture for 2–6 days, it is transferred by catheter into the uterus, with the intention of establishing a successful pregnancy.
