IVF does not lead to premature menopause. In each of your natural menstrual cycles, your body selects a crop of 10-30 primitive eggs to start the ovulation process. These eggs start to grow, but only one egg reaches the mature stage and is ovulated. An IVF cycle salvages many of the extra eggs that would have been wasted in your natural cycle, and encourages them to grow to maturity. This is how multiple mature eggs are produced with each IVF cycle. IVF does not ‘use up’ more eggs than would be used in a natural cycle.
