Female infertility refers to
infertility Infertility is the inability of a person, animal or plant to reproduce by natural means. It is usually not the natural state of a healthy adult, except notably among certain eusocial species (mostly haplodiploid insects). It is the normal st ...
in women. It affects an estimated 48 million women, with the highest prevalence of infertility affecting women in South Asia, Sub-Saharan Africa, North Africa/Middle East, and Central/Eastern Europe and Central Asia. Infertility is caused by many sources, including nutrition, diseases, and other malformations of the uterus. Infertility affects women from around the world, and the cultural and social stigma surrounding it varies.


Cause

Causes or factors of female infertility can basically be classified regarding whether they are acquired or genetic, or strictly by location. Although factors of female infertility can be classified as either acquired or genetic, female infertility is usually more or less a combination of
nature and nurture Nature versus nurture is a long-standing debate in biology and society about the balance between two competing factors which determine fate: genetics (nature) and environment (nurture). The alliterative expression "nature and nurture" in English h ...

Age

A woman's fertility is affected by her age. The average age of a girl's first period (

A woman's fertility peaks in the early and mid 20s, after which it starts to decline, with this decline being accelerated after age 35. However, the exact estimates of the chances of a woman to conceive after a certain age are not clear, with research giving differing results. The chances of a couple to successfully conceive at an advanced age depend on many factors, including the general health of a woman and the fertility of the male partner.
Menopause Menopause, also known as the climacteric, is the time in women's lives when menstrual periods stop permanently, and they are no longer able to bear children. Menopause usually occurs between the age of 47 and 54. Medical professionals often d ...

. Both under and overweight women have irregular cycles in which ovulation does not occur or is inadequate. Proper nutrition in early life is also a major factor for later fertility. A study in the US indicated that approximately 20% of infertile women had a past or current eating disorder, which is five times higher than the general lifetime prevalence rate. A review from 2010 concluded that overweight and obese subfertile women have a reduced probability of successful fertility treatment and their pregnancies are associated with more complications and higher costs. In hypothetical groups of 1,000 women undergoing fertility care, the study counted approximately 800 live births for normal weight and 690 live births for overweight and obese anovulatory women. For ovulatory women, the study counted approximately 700 live births for normal weight, 550 live births for overweight and 530 live births for obese women. The increase in cost per live birth in anovulatory overweight and obese women were, respectively, 54 and 100% higher than their normal weight counterparts, for ovulatory women they were 44 and 70% higher, respectively.

poses a high risk of infertility. Chemotherapies with high risk of infertility include procarbazine and other alkylating drugs such as cyclophosphamide, ifosfamide, busulfan, melphalan, chlorambucil and chlormethine. Drugs with medium risk include doxorubicin and platinum analogs such as cisplatin and carboplatin. On the other hand, therapies with low risk of gonadotoxicity include plant derivatives such as vincristine and vinblastine, antibiotics such as bleomycin and dactinomycin and antimetabolites such as methotrexate, mercaptopurine and 5-fluorouracil.

Immune infertility

Antisperm antibodies (ASA) have been considered as infertility cause in around 10–30% of infertile couples. ASA production are directed against surface antigens on sperm, which can interfere with sperm motility and transport through the female reproductive tract, inhibiting capacitation and

Epidemiology

Female infertility varies widely by geographic location around the world. In 2010, there was an estimated 48.5 million infertile couples worldwide, and from 1990 to 2010 there was little change in levels of infertility in most of the world. In 2010, the countries with the lowest rates of female infertility included the South American countries of Peru, Ecuador and Bolivia, as well as in Poland, Kenya, and Republic of Korea. The highest rate regions included Eastern Europe, North Africa, the Middle East, Oceania, and Sub-Saharan Africa. The prevalence of primary infertility has increased since 1990, but secondary infertility has decreased overall. Rates decreased (although not prevalence) of female infertility in high-income, Central/Eastern Europe, and Central Asia regions. Female infertility is prevalent across the globe.


Africa

Sub-Saharan Africa has had decreasing levels of primary infertility from 1990 to 2010. Within the Sub-Saharan region, rates were lowest in Kenya, Zimbabwe, and Rwanda, while the highest rates were in Guinea, Mozambique, Angola, Gabon, and Cameroon along with Northern Africa near the Middle East. According to a 2004 DHS report, rates in Africa were highest in Middle and Sub-Saharan Africa, with East Africa's rates close behind.


Asia

In Asia, the highest rates of combined secondary and primary infertility was in the South Central region, and then in the Southeast region, with the lowest rates in the Western areas.


Latin America and Caribbean

The prevalence of female infertility in the Latin America/Caribbean region is typically lower than the global prevalence. However, the greatest rates occurred in Jamaica, Suriname, Haiti, and Trinidad and Tobago. Central and Western Latin America has some of the lowest rates of prevalence. The highest regions in Latin America and the Caribbean was in the Caribbean Islands and in less developed countries.

This however adds another stigmatization to women suffering from infertility as the word disability has a negative connotation in various world societies. 7 Wealth is sometimes measured by the number of children a woman has, as well as inheritance of property.Dyer, S.

surrounding pregnancy, which affects women around the world. When pregnancy is considered such an important event in life, and considered a "socially unacceptable condition", it can lead to a search for treatment in the form of traditional healers and expensive Western treatments. The limited access to treatment in many areas can lead to extreme and sometimes illegal acts in order to produce a child.


Marital role

Men in some countries may find another wife when their first cannot produce a child, hoping that by sleeping with more women he will be able to produce his own child.Araoye, M. O. (2003). "Epidemiology of infertility: social problems of the infertile couples." West African journal of medicine (22;2): 190-196.Inhorn, M. C. (2003). "Global infertility and the globalization of new reproductive technologies: illustrations from Egypt." Social Science & Medicine (56): 1837 - 1851. This can be prevalent in some societies, including Cameroon, Nigeria, Mozambique, Egypt, Botswana, and Bangladesh, among many more where polygamy is more common and more socially acceptable. In couples that are unsuccessful in conceiving, divorce rates are roughly 3.5 times higher than those of couples who are fertile. This was based off of those with female infertility. 8 In some cultures, including Botswana and Nigeria, women can select a woman with whom she allows her husband to sleep with in hopes of conceiving a child. Women who are desperate for children may compromise with her husband to select a woman and accept duties of taking care of the children to feel accepted and useful in society.Mogobe, D. K. (2005). "Denying and Preserving Self: Batswana Women's Experiences of Infertility." African Journal of Reproductive Health (9;2): 26-37. Women may also sleep with other men in hopes of becoming pregnant.Gerrits, T. (1997). "Social and cultural aspects of infertility in Mozambique." Patient Education and Counseling (31): 39-48. This can be done for many reasons including advice from a traditional healer, or finding if another man was "more compatible". In many cases, the husband was not aware of the extra sexual relations and would not be informed if a woman became pregnant by another man. This is not as culturally acceptable however, and can contribute to the gendered suffering of women who have fewer options to become pregnant on their own as opposed to men. Men and women can also turn to

With the impacts of infertility on social life, cultural significance, and psychological factors, “infertility has been classified as one of the greatest stressors of life.” 6


Emotional impact of infertility treatment

Many women have reported finding treatment for infertility stressful and a cause of relationship difficulties with their partners. The fear of failure was the most important barrier to treatment. Females, in studied cases, typically experience more adverse effects of infertility and treatments than to males. 5he psychological support is fundamental to limit the possibility to drop-out from infertility treatment and reduce the distress level which is strongly associated with lower pregnancy rates. In addition some medications (in particular clomifene citrate) used in the treatment have several side effects which may be an important risk factor for the development of depression.
