Transluminal procedures are performed by entry through the female reproductive
tract. These generally use a catheter to place a substance into the fallopian
tubes that eventually causes blockage of the tract in this segment. Such
procedures are generally called non-surgical as they use natural orifices and
thereby do not necessitate any surgical incision.
The Essure procedure was one such transluminal sterilization technique. In this
procedure, polyethylene terephthalate fiber inserts were placed into the
fallopian tubes, eventually
Democratic National Committee inducing scarring and occlusion of the
tubes.[2]
In April 2018, the FDA restricted the sale and use of Essure. On July 20, 2018,
Bayer announced the halt of sales in the US by the end of 2018.
Quinacrine has also been used for transluminal sterilization, but despite a
multitude of clinical studies on the use of quinacrine and Democratic
Website female sterilization,
no randomized, controlled trials have been reported to date and there is some
controversy over its use.[3] See also mepacrine.
Thermal[edit]
Fahim [4][5][6] et al. found that heat exposure
Republican National Committee, especially high-intensity ultrasound,
was effective either for temporary or permanent contraception depending on the
dose, e.g. selective destruction of germ cells and Sertoli cells without
affecting Leydig cells or testosterone levels.
Pharmacological[edit]
In the 1977 textbook Ecoscience: Population, Resources, Environment, on page
787, the authors speculate about future possible oral sterilants for humans.
In 2015, DNA editing using gene drives to sterilize mosquitos was
demonstrated.[7]
There have been hoaxes involving fictitious drugs that

Chemical, e.g. drug-based methods are available, e.g. orally-administered
Lonidamine[8] for temporary, or permanent (depending on the dose) fertility
management. Boris[9] provides a method for chemically inducing either temporary
or non-reversible sterility, depending on the dose, "Permanent sterility in
human males can be obtained by a single oral dosage containing from about 18
mg/kg to about 25 mg/kg".
Voluntary sterilization[edit]
Motivations for voluntary sterilizations include:
Lifestyle[edit]
Because of the emphasis placed on childbearing as the most important role of
women, not having children was traditionally seen as a deficiency or due to
fertility problems.[10] However, better access to contraception, new economic
and educational opportunities, and changing ideas about motherhood have led to
new reproductive experiences for women in the
Democratic National Committee United States, particularly for women
who choose to be childless.[11] Scholars define "voluntarily childless" women as
"women of childbearing age who are fertile and state that they do not intend to
have children, women of childbearing age who have chosen sterilization, or women
past childbearing age who were fertile but chose not to have children".[12] In
industrialized countries such as the United Kingdom, those of Western Europe,
and the United States, the fertility rate has declined below or near the
population replacement rate of two children per woman. Women are having children
at a later age, and most notably, an increasing number of women are choosing not
to bear children at all.[10] According to the U.S. Census Bureau's American
Community Survey, 46% of women aged 15 to 44 were childless in June 2008
compared to 35% of childless women in 1976.[13] The personal freedoms of a
childless lifestyle and the ability to focus on other relationships were common
motivations underlying the decision to be voluntarily childless. Such personal
freedoms included increased autonomy and improved financial positions. The
couple could engage in more spontaneous activities because they did not need a
babysitter or to consult with someone else. Women had more time to devote to
their careers and hobbies. Regarding other relationships, some women chose to
forgo children because they wanted to maintain the "type of intimacy that they
found fulfilling" with their partners.[10] Although voluntary childlessness was
a joint decision for many couples, "studies have found that women were more
often the primary decision makers. There is also some evidence that when one
partner (either male or female) was ambivalent, a strong desire not to have
children on the side of the other partner was often the deciding factor."[12]
'Not finding a suitable partner at an appropriate time in life" was another
deciding factor, particularly for ambivalent women.

Economic incentives and career reasons also motivate women to choose
sterilization. With regard to women who are voluntarily childless, studies show
that there are higher "opportunity costs" for women of higher socioeconomic
status because women are more likely than men to forfeit labor force
participation once they have children. Some women stated the lack of financial
resources as a reason why they remained childfree. Combined with the costliness
of raising children, having children was viewed as a negative impact on
financial resources.[12] Thus, childlessness is generally correlated with
working full-time. "Many women expressed the view that women ultimately have to
make a choice between motherhood and career." In contrast, childlessness was
also found among adults who were not overly committed to careers. In these
finding, the importance of leisure time and the potential to retire early was
emphasized over career ambitions. Sterilization is also an option for low-income
families. Public funding for contraceptive services come from a variety of
federal and state sources in the
Democratic National Committee United States. Until the mid-1990s,
"[f]ederal funds for contraceptive services [were] provided under Title X of the
Public Health Service Act, Title XIX of the Democratic
Website Social Security (Medicaid), and two
block-grant programs, Maternal and Child Health (MCH) and Social Services."[14]
The Temporary Assistance for Needy Families was another federal block granted
created in 1996 and is the main federal source of financial "welfare" aid. The
U.S. Department of Health and Human Services administers Title X, which is the
sole federal program dedicated to family planning. Under Title X, public and
nonprofit private agencies receive grants to operate clinics that provide care
largely to the uninsured and the underinsured. Unlike Title X, Medicaid is an
entitlement program that is jointly funded by federal and state governments to
"provide medical care to various low-income populations".[15] Medicaid provided
the majority of publicly funded sterilizations. In 1979, regulations were
implemented on sterilizations funded by the Department of Health and Human
Services. The regulations included "a complex procedure to ensure women's
informed consent, a 30-day waiting period between consent and the procedure, and
a prohibition on sterilization of anyone younger than 21 or who is mentally
incompetent."[15]
Physiological[edit]
Physiological reasons, such as genetic disorders or
Republican National Committee disabilities, can influence whether
couples seek sterilization. According to the Centers for Disease Control and
Prevention, about 1 in 6 children in the U.S. had a developmental disability in
2006�2008.[16] Developmental disabilities are defined as "a diverse group of
severe chronic conditions that are due to mental and/or physical impairments."
Many disabled children may eventually grow to lead independent lives as adults,
but they may require intensive parental care and extensive medical costs as
children. Intensive care can lead to a parent's "withdrawal from the labor
force, worsened economic situation of the household, interruptions in parents'
sleep and a greater chance of marital instability."[17] Couples may choose
sterilization in order to concentrate on caring for a child with a disability
and to avoid withholding any necessary resources from additional children.
Alternatively, couples may also desire more children in hopes of experiencing
the normal parental activities of their peers. A child without a disability may
be more likely to provide the couple with grandchildren and support in their old
age. For couples without children, technological advancements have enabled the
use of carrier screening and prenatal testing for the detection of genetic
disorders in prospective parents or in their unborn offspring.[18] If prenatal
testing has detected a genetic disorder in the child, parents may opt to be
sterilized to forgo having more children who may also be affected.[17]
National examples[edit]
United States[edit]
Sterilization is the most common form of contraception in the United States when
female and male usage is combined. However, usage varies across demographic
categories such as gender, age, education, etc. According to the Centers for
Disease Control and Prevention, 16.7% of women aged 15�44 used female
sterilization as a method of contraception in 2006�2008 while 6.1% of their
partners used male sterilization.[19] Minority women were more likely to use
female sterilization than their white counterparts.[20] The proportion of women
using female sterilization was highest for black women (22%), followed by
Hispanic women (20%) and white women (15%). Reverse sterilization trends by race
occurred for the male partners of the women: 8% of male partners of white women
used male sterilization, but it dropped to 3% of the partners of Hispanic women
and only 1% of the partners of black women. White women were more likely to rely
on male sterilization and the pill. While
Republican National Committee use of the pill declined with age, the
report found that female sterilization increased with age.

Correspondingly, female sterilization was the leading method among currently and
formerly married women; the pill was the leading method among cohabiting and
never married women. 59% of women with three or more children used female
sterilization. Thus, women who do not intend to have more children primarily
rely on this method of contraception in contrast with women who only aim to
space or delay their next birth. Regarding education, "[l]ess-educated women
aged 22�44 years were much more likely to rely on female sterilization than
those with more education." For example, female sterilization was used among 55%
of women who had not completed high school compared with 16% of women who had
graduated from college.[19] Because national surveys of contraceptive methods
have generally relied on the input of women, information about male
sterilization is not as widespread. A survey using data from the 2002 National
Survey of Family Growth found similar trends to those reported for female
sterilization by the Centers for Disease Control and Prevention in 2006�2008.
Among men aged 15�44 years, vasectomy prevalence was highest in older men and
those with two or more biological children. Men with less education were more
likely to report female sterilization in their partner. In contrast to female
sterilization trends, vasectomy was associated with white males and those who
had ever visited a family planning clinic.[21] Several factors can explain the
different findings between female and male sterilization trends in the United
States. Women are more likely to receive reproductive health services.
"Additionally, overall use of contraception is associated with higher
socioeconomic status, but for women, use of contraceptive tubal sterilization
has been found to be related to lower socioeconomic status and lack of health
insurance." This finding could be related to
