Assisted reproductive technology (ART) is the technology used to achieve pregnancy in procedures such as fertility medication, in vitro fertilization and surrogacy. It is reproductive technology used primarily for infertility treatments, and is also known as fertility treatment. It mainly belongs to the field of reproductive endocrinology and infertility, and may also include intracytoplasmic sperm injection (ICSI) and cryopreservation. Some forms of ART are also used with regard to fertile couples for genetic reasons (preimplantation genetic diagnosis). ART is also used for couples who are discordant for certain communicable diseases; for example, HIV to reduce the risk of infection when a pregnancy is desired.
In the US, the Centers for Disease Control and Prevention (CDC)--which is required as a result of the 1992 Fertility Clinic Success Rate and Certification Act to publish the annual ART success rates at U.S. fertility clinics--defines ART to include "all fertility treatments in which both eggs and sperm are handled. In general, ART procedures involve surgically removing eggs from a woman's ovaries, combining them with sperm in the laboratory, and returning them to the woman's body or donating them to another woman." According to CDC, "they do not include treatments in which only sperm are handled (i.e., intrauterine--or artificial--insemination) or procedures in which a woman takes medicine only to stimulate egg production without the intention of having eggs retrieved."
The WHO also defines ART this way.
Most fertility medications are agents that stimulate the development of follicles in the ovary. Examples are gonadotropins and gonadotropin releasing hormone.
Techniques usually used in in vitro fertilization include:
Less commonly used techniques in in vitro fertilization are:
Other assisted reproduction techniques include:
The majority of IVF-conceived infants do not have birth defects. However, some studies have suggested that assisted reproductive technology is associated with an increased risk of birth defects. Artificial reproductive technology is becoming more available. Early studies suggest that there could be an increased risk for medical complications with both the mother and baby. Some of these include low birth weight, placental insufficiency, chromosomal disorders, preterm deliveries, gestational diabetes, and pre-eclampsia(Aiken and Brockelsby).
In the largest U.S. study, which used data from a statewide registry of birth defects, 6.2% of IVF-conceived children had major defects, as compared with 4.4% of naturally conceived children matched for maternal age and other factors (odds ratio, 1.3; 95% confidence interval, 1.00 to 1.67). ART carries with it a risk for heterotopic pregnancy (simultaneous intrauterine and extrauterine pregnancy). The main risks are:
Other risk factors are:
Sperm donation is an exception, with a birth defect rate of almost a fifth compared to the general population. It may be explained by that sperm banks accept only people with high sperm count.
Usage of assisted reproductive technology including ovarian stimulation and in vitro fertilization have been associated with an increased overall risk of childhood cancer in the offspring, which may be caused by the same original disease or condition that caused the infertility or subfertility in the mother or father.
That said, In a landmark paper by Jacques Balayla et al. it was determined that infants born after ART have similar neurodevelopment than infants born after natural conception.
In case of discontinuation of fertility treatment, the most common reasons have been estimated to be: postponement of treatment (39%), physical and psychological burden (19%, psychological burden 14%, physical burden 6.32%), relational and personal problems (17%, personal reasons 9%, relational problems 9%), treatment rejection (13%) and organizational (12%) and clinic (8%) problems.
Many Americans do not have insurance coverage for fertility investigations and treatments. Many states are starting to mandate coverage, and the rate of use is 278% higher in states with complete coverage.
There are some health insurance companies that cover diagnosis of infertility but frequently once diagnosed will not cover any treatment costs.
2005 approximate treatment/diagnosis costs (United States, costs in US$):
Another way to look at costs is to determine the expected cost of establishing a pregnancy. Thus if a clomiphene treatment has a chance to establish a pregnancy in 8% of cycles and costs $500, the expected cost is $6,000 to establish a pregnancy, compared to an IVF cycle (cycle fecundity 40%) with a corresponding expected cost of $30,000 ($12,000/.4).
For the community as a whole, the cost of IVF on average pays back by 700% by tax from future employment by the conceived human being.
In the United Kingdom, all patients have the right to preliminary testing, provided free of charge by the National Health Service. However, treatment is not widely available on the NHS and there can be long waiting lists. Many patients therefore pay for immediate treatment within the NHS or seek help from private clinics.
The guidelines also say women aged between 40 and 42 should be offered one cycle of IVF on the NHS if all of the following additional criteria are also met: They have never had IVF treatment before, have no evidence of low ovarian reserve (this is when eggs in the ovary are low in number or low in quality) and have been informed of the additional implications of IVF and pregnancy at this age. However, if tests show IVF is the only treatment likely to help them get pregnant, women should be referred for IVF straight away.
This policy is often modified by local Clinical Commissioning Groups, in a fairly blatant breach of the NHS Constitution for England which provides that patients have the right to drugs and treatments that have been recommended by NICE for use in the NHS. For example, the Cheshire, Merseyside and West Lancashire Clinical Commissioning Group insists on additional conditions:
In Sweden, official fertility clinics provide most necessary treatments and initial workup, but there are long waiting lists, especially for egg donations, since the donor gets just as low reward as the receiving couple are charged. However, there are private fertility clinics.
Some treatments are covered by OHIP (public health insurance) in Ontario and others are not. Those with bilaterally blocked fallopian tubes and under 40 have treatment is covered but are still required to pay lab fees (around $3,000-4,000). Coverage varies in other provinces. Most other patients are required to pay for treatments themselves.
Israel's national health insurance, which is mandatory for all Israeli citizens, covers nearly all fertility treatments. IVF costs are fully subsidized up to the birth of two children for all Israeli women, including single women and lesbian couples. Embryo transfers for purposes of gestational surrogacy are also covered.
The national public health system of New Zealand covers IVF treatment in specific circumstances only, based on a 'points for conception challenges' equation. Publicly funded IVF treatments are limited (between one and three treatments dependent on criteria) and are subject to substantial wait-lists, dependent on local health funding region, which raises potential inequity of ART support across the country. Infertility testing through blood tests can be covered by public funding, however in the absence of explicit gynecological complications, additional investigations are may not be covered publicly. Investigation such as a hysterosalpingogram may be covered, but the wait-list could be in excess of six weeks, whereas a privately sourced HSG can cost $NZ900 but is readily available. Many New Zealanders select self-funded IVF cycles, at approximately $NZ10,000 per cycle, and other forms of ART, such as IUI, at approximately $NZ1200, using the services of private fertility clinics, which in itself is a growing local industry. Individuals using private services are generally not covered under personal health insurance policies in New Zealand.
On 27 January 2009, the Federal Constitutional Court ruled that it is unconstitutional, that the health insurance companies have to bear only 50% of the cost for IVF. On 2 March 2012, the Federal Council has approved a draft law of some federal states, which provides that the federal government provides a subsidy of 25% to the cost. Thus, the share of costs borne for the pair would drop to just 25%.
In Jordan, not everyone has insurance coverage for fertility investigation and treatment. Army forces cover the army members for all infertility investigations and treatments. It also covers three trials of IVF in primary infertility cases. Some health insurance companies cover the diagnosis and the treatment of infertility for those with government health insurance, but it will not cover any of the assisted reproductive techniques. In private sector, there are many centers offering private treatment for infertility including the assisted reproductive techniques. Conventional I.V.F cost 1170JD = 1654 US$, ICSI cost 1270 JD = 1797 US$ Both prices include assisted hatching. But does not include the cost of medication which averages between 500-700 JD which equals around 700-1000 US$ 
Some couples find it difficult to stop treatment despite very bad prognosis, resulting in futile therapies. This may give ART providers a difficult decision of whether to continue or refuse treatment.
Some assisted reproductive technologies can in fact be harmful to both the mother and child. Posing a psychological and a physical health risk, which may impact the ongoing use of these treatments. The adverse effects may cause for alarm, and they should be tightly regulated to ensure candidates are not only mentally, but physically prepared.
Films and other fiction depicting emotional struggles of assisted reproductive technology have had an upswing in the latter part of the 2000s decade, although the techniques have been available for decades. Yet, the number of people that can relate to it by personal experience in one way or another is ever growing, and the variety of trials and struggles are huge.
In addition, reproduction and pregnancy in speculative fiction has been present for many decades.
