How USG confirms that there is ovulation?
Sonography does appear to be very reliable in confirming ovulation once ovulation has occurred. Disappearance of the follicle is noted in 91 percent of cases after ovulation and a decrease in follicle size occurs in another 9 percent. Other signs suggesting that ovulation has occurred are the appearance of cul-de-sac fluid, particularly when it was not present in a previous scan, or the development of intratollicular echoes suggesting the formation of a hemorrhagic corpus luteum.
