To compare the number of mature oocytes following a GnRH antagonist in-vitro fertilization stimulation cycle when comparing trigger day timing decision by physicians versus an artificial intelligence-based algorithm

Examination of all patients undergoing an ovarian stimulation cycle utilizing the GnRH antagonist protocol for oocyte cryopreservation or for fertilization via intracytoplasmic sperm injection (ICSI) (any treatment where oocytes are denuded and maturity may be assessed). The number of mature oocytes will be compared between cycles where trigger day timing was decided by the treating physician versus an artificial intelligence-based algorithm.

Inclusion Criteria:

• All patients undergoing an ovarian stimulation cycle utilizing the GnRH antagonist protocol for oocyte cryopreservation or for fertilization via intracytoplasmic sperm injection (ICSI) (any treatment where oocytes are denuded and maturity may be assessed).

Exclusion Criteria:

• Loss to follow-up, patient retracts consent to participate

Data regarding patient demographics, characteristics and cycle outcomes (anynomized)
