No, women are born with a specific egg reserve. A portion of this reserve is naturally lost until puberty. From puberty onwards, the ovaries select and prepare eggs for maturation each month within a natural cycle, which will develop in the next menstrual period. Of these selected eggs, usually only one or two fully develop and ovulate, creating a suitable environment for pregnancy. If pregnancy does not occur, the cycle restarts the following month. The eggs collected during in vitro fertilization (IVF) treatment are those naturally prepared for that specific month's cycle, which would normally be lost. This treatment does not deplete a woman's overall egg reserve; as a new group of eggs continues to develop from the reserve each month.
