The relationship between controlled ovarian stimulation protocol, meiotic spindle visibility, position of the meiotic spindle relative to the polar body in the human oocyte, and clinical outcomes following ICSI

The relationship between controlled ovarian stimulation protocol, meiotic spindle visibility, position of the meiotic spindle relative to the polar body in the human oocyte, and clinical outcomes following ICSI

Purpose To investigate the effects of different controlled ovarian stimulation (COS) protocols, including the progestin‐primed ovarian stimulation (PPOS), long, short, and the gonadotropin‐releasing hormone antagonist protocols, on meiotic spindle visibility and position within the oocyte and clinic...

Zusammenfassung:Purpose To investigate the effects of different controlled ovarian stimulation (COS) protocols, including the progestin‐primed ovarian stimulation (PPOS), long, short, and the gonadotropin‐releasing hormone antagonist protocols, on meiotic spindle visibility and position within the oocyte and clinical outcomes following ICSI. Methods Before ICSI, spindle position (θ) just below the polar body (PB) was defined as 0° and categorized as follows: θ = 0°, 0°
