Fixed versus Flexible Gonadotropin Releasing Hormone Antagonist Protocol in Controlled Ovarian Stimulation for Invitro Fertilization in Women with Polycystic Ovary Syndrome.

Objective: This study was conducted to compare the results of fixed versus flexible GnRH antagonist protocols in controlled ovarian stimulation for Intra Cytoplasmic Sperm Injection (ICSI) in patients with PCOS.

Materials And Methods: A randomized clinical trial was performed on 100 PCOS women, who were admitted to a tertiary infertility clinic and were candidate for IVF/ICSI. They were divided into two groups based on the GnRH antagonist protocol.

Ovarian stimulation for emergency fertility preservation in cancer patients: A case series study.

•We used Random-Start for the IVF cycle in urgent settings of gynecological cancer.•Oocytes can be obtained at any time before cancer treatment efficiently.•Oocyte maturity rates were comparable with conventional antagonist protocol.
