Couples who are having difficulty conceiving children are increasingly turning to in-vitro fertilization (IVF) treatment. A patient undergoes 1 month of initial screening appointments, then with 50% probability commences with a sequence of IVF treatment cycles.

It is estimated that among patients who go through the first cycle, 30% do not return for a second cycle (because of a successful pregnancy on the first try, financial limitations, personal reasons, etc.) Of those who do return for a second cycle, they undergo on average 1.5 more cycles (in addition to the first cycle).
