Assisted Reproductive Technology

Fertility is the ability to reproduce, having children. Every human being begins life as a fertilized egg, the result of the combination of the male sperm and female egg. But despite that nature gave us all humans this ability, often there are natural obstacles that prevent us from conceiving. In more than 10% of all infertile couples, there is no reason for the infertility, and approximately 5 % of cases, the problem seems to disappear on its own. Often, an infertile couple finds that the mere fact of exposing the problem to a fertility specialist psychological stress relaxes to obstacles. Only 35 % of apparently infertile couples cannot conceive a child, they are sterile incurable.

When a girl is born has about 400,000 eggs in her ovaries. The number decreases to about 10,000 to stay in puberty, when the body of a girl is ready for playback. Only about 400 eggs fail to develop fully. In adulthood, one egg matures each month one of the ovaries and released. This is called ovulation. If a sperm into the uterus and it is fused with the egg, it is said that the egg has been fertilized. Fertilization the human embryo is a new life. An adult male produces about 250 million sperm a day in his testicles. "Sperm are tiny cells in a manner similar to a tadpole, which ejaculate and introduced into the vagina in women during intercourse" (Ranucci, 18). A man can produce up to 70 or more years old.

The most common causes of male infertility are unable to produce sperm, or not producing the number of them is normal and active enough to swim towards the egg, through its outer surface and combined with it. Even in fertile men, maybe even 40 percent of the sperm may be abnormal. A count of zero or very few sperm may be the result of a blockage in the tubes that carry sperm to the penis, or a defect in the testes or the hormonal system that stimulates the production of sperm. "Some medicines or radiation treatments, as in the case of cancer, can also reduce sperm count or kill them" (Pellicer, Assisted Reproduction in Spain). Ill with mumps in adulthood may be another cause of male infertility.

Sperm production is very sensitive to temperature, and low sperm count can be the result of excessive wear very thick clothes or tight underwear, which holds the testicles too hot. Sitting too long can also have a similar effect. Those who may be affected thereby are truckers, taxi drivers and which are necessarily subject to a table because of their work. In general, men can be the cause of infertility as much as women.

There are many reasons why women may be unable to have children. It is possible that your ovaries do not release eggs or do not ovulate regularly,...

Approximately 11% of women in the United States between the ages of fifteen and forty-four have difficulty conceiving a child due to the infertility of one or both of the partners. Many of these couples turn to assisted reproductive technology as a potential way to help them have a child. Reproductive technology is the use of medical techniques to enhance fertility and increase the probability of conceiving a child. Methods of reproductive technology include artificial insemination, gamete intrafallopian transfer (GIFT), in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), surrogacy, and zygote intrafallopian transfer (ZIFT). Although these technologies offer hope, they also are expensive, can cause psychological harm, and are often not successful. Feminists in particular are concerned about the social and psychological ramifications of assisted reproductive technology on women, and see their use as a way to reinforce traditional gender roles and expectations and for women to give up their power and control over their own bodies. More research is needed to better understand the psychosocial effects of assisted reproductive technologies on infertile couples in general and women in particular.

Overview

Infertility is the inability to get pregnant after trying for one year. It has been estimated that approximately 11% of women in the United States have difficulty conceiving a child. According to the Centers for Disease Control and Prevention, in 2013, approximately 6 percent of married women between the ages of fifteen and forty-four in the United States are unable to get pregnant after a year of unprotected sex. Previously, this usually meant that the couple would continue to try by natural means to have a child or make the decision to adopt or remain childless. However, medical science has advanced to the point where a number of technologies are available that can help women conceive. These assisted reproductive technologies comprise the use of medical techniques to enhance fertility and increase the probability of conceiving a child. Methods of reproductive technology include artificial insemination, gamete intrafallopian transfer (GIFT), in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), surrogacy, and zygote intrafallopian transfer (ZIFT). The use of assisted reproductive technology becomes increasingly important as greater numbers of women postpone childbearing.

Artificial Insemination

Two of the most widely known methods of assisted reproductive technology are artificial insemination and in vitro fertilization. Artificial insemination is a medical or surgical procedure in which a catheter is used to deposit sperm collected from a donor directly into the uterus of the woman trying to become pregnant. As with unassisted reproduction, artificial insemination often needs to be repeated before pregnancy occurs. In vitro fertilization, on the other hand, is a laboratory procedure in which an egg is removed from a woman's body, fertilized with donated sperm, and transferred to the woman's uterus to begin pregnancy. The externally fertilized egg does not need to be transplanted immediately, but may also be cryogenically frozen for future use. In vitro fertilization literally means fertilization that takes place "in glass" (i.e., a Petri dish) as opposed to in vivo fertilization that takes place in a live organism. In vitro fertilization is often combined with drug therapy to increase the probability of the woman conceiving. Zygote intrafallopian transfer is an in vitro fertilization technique in which the egg and sperm are combined in a laboratory and the fertilized eggs (i.e., zygotes) are implanted into the woman's fallopian tubes. Gamete intrafallopian transfer is an artificial reproductive technique in which eggs and sperm are directly injected into a woman's fallopian tubes. Gamete intrafallopian transfer is an alternative to in vitro fertilization. In vitro fertilization can also be used to create a baby that is gestated by a surrogate mother. This is a woman who fulfills the basic functions of a biological mother in gestating and bearing a child, but not the social role of mother in rearing the child after birth. In particular, a surrogate mother is a woman who gestates an artificially inseminated egg and gives birth to a baby for another.

In vitro fertilization In vitro fertilization increases the probability of multiple births. For example, between the years of 1980 and 1998, the rate of triples or larger multiples increased 420% (Schaefer, 2002). In 2011the twin birth rate was 8.1 percent; the rate for triplets or a higher-order multiple birth rate was 137 per 100,000. Although some couples readily embrace the idea of multiple births, not all do and not all are financially able to support and raise the potentially large multiples of children that can result from in vitro fertilization. Despite the old adage that two can live as cheaply as one, multiple babies require similar multiples for food, clothing, health care, education, and other needs. In addition, in vitro fertilization itself is a costly and time consuming process. In 2012, according to the American Society for Reproductive Medicine, it was estimated that the cost of in vitro fertilization is approximately $12,400 per procedure without any guarantee of success. This makes in vitro fertilization an option only for those who can afford the costs. Conflict theorists in particular note that women in lower economic strata are unable to afford these treatments although they are typically allowed access to low cost contraception.

Cloning

Fertilizing an egg with a sperm is not the only type of reproductive technology, however. Advances in cloning technologies and genetic engineering may offer those wishing to have children other options in the near future. Cloning is the process of making a genetically identical copy (i.e., a clone). When applied to human beings for the purposes of creating a new human being, cloning is typically referred to as human cloning or human reproductive cloning. Human cloning is of great ethical concern to most observers. According to the American Medical Association, cloning may someday be a viable reproductive technology requiring minimal genetic input from another person (AMA, 1999). However, at this time the techniques used in human cloning could potentially endanger the developing fetus. Somatic cell nuclear transfer has not been refined nor yet proven to be safe in the long term. In addition, it is expected that there would be a high miscarriage rate from the transplantation of cloned fetuses. Further, the state of the art in cloning technology is such that the risk of developmental anomalies precludes the use of cloning as a reproductive technology at this time. However, even if all the technological difficulties are resolved, human cloning is thought to be potentially harmful to individuals from a psychosocial perspective. There are thirteen US states—Arkansas, California, Connecticut, Iowa, Indiana, Massachusetts, Maryland, Michigan, North Dakota, New Jersey, Rhode Island, South Dakota, and Virginia—that have bans on reproductive cloning.

Another technology that shows promise for use in assisted reproduction in the future is genetic engineering. This comprises a set of techniques by which the genetic contents of living cells are directly and intentionally altered. Genetic engineering can be used to modify existing genes or to introduce new material from another organism. Genetic engineering is used for a number of purposes, including attempts to modify defective human cells in an effort to treat certain genetic diseases. Many observers have serious ethical concerns about genetic engineering in general, and with the application of genetic engineering to humans in particular. For example, the use of genetic technology could potentially lead to the creation of "designer babies" which have been genetically manipulated to have higher IQs or various other desired physical or personality traits. This could lead to increasing disparity between the upper and lower classes, a situation of questionable ethics.

Further Insights

Infertility is considered by most observers to constitute a major life crisis. The question, however, is why this is so. Although in the recent past, many in the medical community believed infertility to be a psychological problem in most cases, today it is believed that infertility stems from physiological causes. As such, infertility has been medicalized, as has many routine situations experienced by women: dysmenorrheal (painful menstruation), premenstrual syndrome, pregnancy, and childbirth. Although on the one hand this means that pain may be controlled and the health and safety of both mother and child better ensured during gestation, labor, and delivery, on the other hand, many feminist theorists dislike this trend, believing that it views...
