Final answer:
The fertility of a human female is dependent on the nutrition of her mother during pregnancy. Infants are born with the total number of eggs they will produce in a lifetime, and egg development occurs in-utero.
Step-by-step explanation:
The fertility of a human female is dependent on the nutrition of her mother during pregnancy since infants are born with the total number of eggs that they will produce in a lifetime with egg development occurring in-utero.
When a baby girl is born, her ovaries contain all of the eggs they will ever produce, but these eggs are not fully developed. They start to mature and develop only after she starts having menstrual periods at about age 12 or 13. One egg typically matures each month until menopause.
Therefore, the nutrition a female receives while in utero can impact the number and quality of eggs she will have later in life, potentially affecting her fertility.
