The serial ultrasonic monitoring of the ovarian follicles used to identify maturation status of eggs is known as follicular monitoring. It is used to assess the size of the follicle that supports the growing egg and for determining the thickness of the uterine lining. Follicle monitoring aims at providing information about the number of mature eggs that will ovulate and to ensure that this is accomplished safely.
When the eggs are mature, patients are advised to have planned relations or Intrauterine Insemination or to use the egg collection for an In-Vitro Fertilization Cycle. This process enables the Doctor to understand the present status of the uterus, endometrium and ovaries. Abnormalities in these findings could help to explain why a woman may have difficulty conceiving. It also identifies ovarian cysts, pelvic collection, hydrosalpinx etc.
