Final answer:
Pronatalism is the belief that encourages the bearing of children, which can influence cultural practices and governmental policies, including restriction of birth control.
Step-by-step explanation:
The concept reflected in fertility worship and religious prohibitions of birth control is pronatalism. Pronatalism is the belief that promotes having children and can manifest in various ways within a society, including cultural pressure to bear children, economic incentives for families with more children, and policies that restrict access to or discourage birth control. It often arises from concerns about a nation's demographic trends, such as aging populations or declining birth rates, and can be a response to issues like labor shortages or the desire for population growth. However, pronatalist policies can lead to a conflict of interest between government targets and individual rights, especially when they result in negative measures such as forced sterilizations or abortions, as alleged in some local implementation of policies in China.
