Therefore, the aggregate demand curve must slope downwards for different reasons. In fact, there are three reasons why the aggregate demand curve exhibits this pattern: the wealth effect, the interest-rate effect, and the exchange-rate effect.
The average IVF cost is $12,000, but it can be as much as $15,000 or may be as low as $10,000. It's rarely lower than that. These prices are for one cycle of IVF. One study asked couples at a fertility clinic to track all their out-of-pocket expenses over a period of 18 months.
If a clinic charges only $6000 for IVF, that is certainly a lower than average price. However, if their success rates are low and it takes more cycles to have a baby - there may not be any cost savings. One successful IVF cycle for $10,000 is better than 2 cycles for $6000 each (plus medications) to have a success.
