abstract = "OBJECTIVE: To describe and demonstrate a simple and secure procedure for laparoscopic autotransplantation of fragmented ovarian cortical tissue in women with diminished ovarian reserve as part of in vitro activation (IVA) of ovarian follicles.DESIGN: Step-by-step video explanation of the surgical procedure with still pictures and surgical video clips to demonstrate the detailed technique.SETTING: Fertility clinic and obstetrics and gynecology department at a university hospital.PATIENT(S): Women with idiopathic diminished ovarian reserve and indication for in vitro fertilization (IVF), aged 25 to 39 years with an antral follicle count bilaterally of ≤5, antim{\"u}llerian hormone level of ≤5 pmol/L, and two ovaries.INTERVENTION(S): The laparoscopic autotransplantation consists of six steps: [1] obtaining ovarian cortical biopsy samples, [2] preparing the peritoneal pocket, [3] fragmenting the ovarian cortical tissue into pieces of approximately 1 mm3, [4] installing the tissue fragments into a catheter, [5] transplanting the tissue fragments into the peritoneal pocket, and [6] closing the peritoneal pocket with a surgical clip. After the procedure, the patients are evaluated with blood samples and ultrasound scans followed by controlled ovarian stimulation.
