Here's a breakdown of what it encompasses:
* Biological Factors: This includes having functioning reproductive organs (ovaries and uterus in females, testes in males), producing viable eggs and sperm, and the ability to conceive and carry a pregnancy to term.
* Physiological Factors: This refers to hormonal balance, proper functioning of the reproductive system, and overall health.
* Social and Environmental Factors: While not directly related to biological function, factors like age, lifestyle choices, stress levels, and environmental exposure can all impact fertility.
It's important to note that fertility is not always a guarantee, and many individuals face challenges with conceiving or carrying a pregnancy.
