Natural fertility

Birth control has dramatically improved the ability of all women to participate actively and with dignity in economies across the world.

[9] In sub-Saharan Africa where gender disparities in education are more prevalent, fertility rates are the highest in the world.

Child marriage in India primarily occurs in girls living in poor socioeconomic conditions.

For example, less developed areas, including, but not limited to those extending throughout inland Africa lack access to the drugs necessary to control fertility or informative lessons describing their correct usage.

However, if the duration of lactation is cut short due to use of a formula substitute or the woman has multiple births, the number of offspring could exceed 20.

Even if a woman does not take contraceptives, lacks knowledge of family planning, or does not practice regulated fertility, she might not be able to conceive.

Over the past half century, there has been an increase in scientific data supporting the decline in male sperm count.

For example, as more regions move away from agriculture children are no longer needed to help with labor and fertility rates and family size tend to decrease.

[18] Developing countries in the early stages of the demographic transition are characterized by high fertility and mortality rates which can be attributed to the lack of medical interventions like birth control and modern technology.

Conversely, developed countries in the later stages of the demographic transition experience lower fertility and mortality rates due to the accessibility of contraception, the pursuit of higher education in women, and marriage at a later age.

[19] Coale's theory can be observed in sub-Saharan Africa as countries residing within this region have fertility levels that are declining at a much slower rate than before and have one of the highest projected population growths compared to other areas of the world.

[10] Individuals inhabiting sub-Saharan Africa have slowly rejected Coale's second precondition for fertility decline which, as stated before, is willingness.

Despite the discrepancy between preferred child bearing and natural fertility, women in Africa have reported they don't use any form of contraception to prevent pregnancies.

The 28-day menstrual cycle is depicted; the cycle starts at the onset of the age at menarche.
This picture portrays the different stages a woman will experience between first becoming fertile at menarche through menopause. The different colors on the graph represent different things as well. The red stands for areas relating to a woman's menstrual cycle, the green represents marriage, blue means birth, and black regards menopause and conception at different areas of the diagram. The purple arrows show the period of gestation following conception, and the orange arrows show lactational infecundability.
Some tribes of the San people are considered to practice natural fertility because they do not use any forms of birth control
In the image, there are three separate pictures that depict each subcategory in a visual nature. The finance is represented by U.S currency, religion is depicted through an amish school house, and family planning is portrayed by a sex symbol.
The three main reasons for practicing natural fertility include financial status, accessibility to family planning, and religious influences. [1] [2] [3]
