The purpose of this phase 2 dose-ranging trial is to investigate the effects of FE 999302 on parameters influencing pregnancy rates in women undergoing Controlled Ovarian Stimulation (COS) with follitropin delta in a long gonadotropin releasing hormone (GnRH) agonist protocol.
Furthermore, the study intends:

| Number of good-quality blastocysts on Day 5 after oocyte retrieval | Quality of blastocysts was assessed by blastocyst expansion and hatching status, blastocyst inner cell mass grading, and trophectoderm grading. The scoring was based on the classification system by Gardner and Schoolcraft, with additional categories for inner cell mass (degenerative or no inner cell mass) and trophectoderm (degenerative or very large cell). | On Day 5 after oocyte retrieval |

| Number and quality of blastocysts on Day 5 after oocyte retrieval | Blastocyst quality was assessed by blastocyst expansion and hatching status, blastocyst inner cell mass grading, and trophectoderm grading. The scoring was based on the classification system by Gardner and Schoolcraft, with additional categories for inner cell mass (degenerative or no inner cell mass) and trophectoderm (degenerative or very large cells). The total number of blastocysts and the number of blastocysts per quality category will be reported. | On Day 5 after oocyte retrieval |
