    Antral follicles are cells early in the process of developing from an oogonium into a mature oocyte. A physician may use a transvaginal ultrasound to visualize and count the number of antral follicles in each of a woman's ovaries in order to determine her ovarian reserve; however AFC is not predictive of embryo quality. [12]

    en.wikipedia.org/wiki/Antral_follicle

    There are three categories when performing an ultrasound to cheek the antral follicle count: Low follicle count (1-3): low ovarian reserve and increased risk of menopause in the next 7 years. Normal follicle count (4-24): Normal follicle amount for women in reproductive age. High follicle count (>=): High risk of hyperandrogenism. It has been ...

    Under ultrasound guidance, the operator inserts a 16.5 gauge × 11.8″ (1.6 mm × 300 mm outer diameter) needle through the vaginal wall and into an ovarian follicle, taking care not to injure nearby organs and blood vessels. The other end of the needle is attached to a suction device.

    Regarding antral follicle count, with the GnRH antagonist protocol initial follicular recruitment and selection is undertaken by endogenous endocrine factors prior to starting the exogenous hyperstimulation. This results in a smaller number of growing follicles when compared with the standard long GnRH agonist protocol.

  6. Ovulation induction - Wikipedia

    en.wikipedia.org/wiki/Ovulation_induction

    During ovulation induction, it is recommended to start at a low dose and monitor the ovarian response with transvaginal ultrasound, including discernment of the number of developing follicles. Initial exam is most commonly started 4–6 days after last pill. Serial transvaginal ultrasound can reveal the size and number of developing follicles.

  7. In vitro fertilisation - Wikipedia

    en.wikipedia.org/wiki/In_vitro_fertilisation

    In vitro fertilisation (IVF) is a process of fertilisation in which an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, then removing an ovum or ova (egg or eggs) from her ovaries and enabling a man's sperm to fertilise them in a culture medium in a laboratory.

    en.wikipedia.org/wiki/Folliculogenesis

    In addition, follicles that have formed an antrum are called antral follicles or Graafian follicles. Definitions differ in where this shift occurs in the staging given above, with some stating that it occurs when entering the secondary stage, [ 2 ] and others stating that it occurs when entering the tertiary stage.

  9. In vitro maturation - Wikipedia

    en.wikipedia.org/wiki/In_vitro_maturation

    A secondary follicle is formed with a few granulosa cell layers, as well as a theca layer. Finally before ovulation, a tertiary follicle is formed containing a follicular-fluid filled antrum. [6] Of these small antral follicles, 1 will become dominant and ovulate (in monoovulatory species).
