  • How Ovarian and Antral Follicles Relate to Fertility

    Aug 29, 2020 · Follicle growth and development are tracked during fertility treatments. During superovulation (used during IVF treatment ), the goal is to stimulate the ovaries to develop several mature follicles at once. An ultrasound exam, also known as an antral follicle count (AFC), may be performed as a part of fertility testing.


    Primordial follicleThis represents the earliest stage of follicular development. Primordial follicles form during early foetal development and are typically located within the peripheral cortex, just beneath the tunica albuginea. Each primordial follicle consists of a primary oocyte surrounded by a simple squamous follicular epithelium.

    The uterus, the hollow, pear-shaped organ where a baby grows, contracts throughout a woman's menstrual cycle. If the uterus contracts too strongly, it can press against nearby blood vessels, cutting off the supply of oxygen to the muscle tissue of the uterus. Pain results when part of a muscle briefly loses its supply of oxygen.
