In cycles with frozen embryos, pregnancy rates per embryo transfer are the same whether the cycle is natural or substituted (with medication). No medication is needed for a natural cycle, which reduces the cost of treatment. However, setting a precise transfer date is more complicated than a substituted cycle.
During endometrial preparation, is it better to do the natural cycle or the substituted cycle?
