During ovulation treatment, if multiple follicles are found to be growing in both ovaries and each follicle is relatively large, it is recommended to abandon ovulation treatment. This is because the growth of multiple follicles will lead to a large increase of estrogen in the body, and the increase of estrogen will often lead to water and sodium retention in the body, which may lead to ovarian hyperstimulation and cause corresponding clinical symptoms, such as large amount of ascites, loss of appetite, abdominal discomfort, low urine and other clinical symptoms, which need to be given urgent treatment. The growth of follicles must be monitored by ultrasound. If multiple follicles are found to be growing and relatively large, it is recommended that ovulation treatment be abandoned for that month.
