Summary Introduction
To determine:
The factors or events that can prevent sperm from reaching the secondary oocyte.
Introduction:
Secondary oocytes are derived from primary oocytes which undergo meiosis I to form this structure. Two chromatids are present in each chromosome of the secondary oocyte. Ovum is formed from secondary oocyte when it undergoes the meiosis II.
