Brief summary

There are several approaches to the timing of antagonist administration in IVF/ICSI cycles. The primary goal is indeed to prevent premature ovulation, which could jeopardize the success of the cycle There is an emerging concept that suggests that the progesterone produced by the corpus luteum (formed after ovulation) might be sufficient to prevent further ovulation, obviating the need for antagonist or exogenous progesterone administration. This hypothesis relies on the natural regulatory mechanisms of the menstrual cycle to maintain a progesterone-dominated environment post-ovulation. We hypothesized that this approach would minimize treatment costs /burden without having an impact on the outcome.
