Is it a failure if the follicle doesn’t break after IUI?

An unruptured follicle after artificial insemination does not make fertilization easy, but it is not necessarily a failure.
Artificial insemination is usually operated 1~2 days before ovulation. If transvaginal ultrasound monitoring of follicles is performed immediately after artificial insemination, the diameter of the dominant follicle at this time is about 18mm, and the follicle rupture takes about 24 hours, so you can’t be too anxious for follicle monitoring.
If the dominant follicle does not rupture on ultrasound monitoring 24 hours after IUI, then there are remedial measures. Injectable human chorionic gonadotropin can be given and follicle rupture occurs in the vast majority of cases in about 24 hours. Sperm can usually survive in the woman’s body for 2 to 3 days, at which point there is a chance of pregnancy.
If this IUI fails, it is recommended to take a blood test on the 2nd to 3rd day of menstruation again for sex hormone 6 to understand ovarian function, and to closely monitor the size of the follicle for the next IUI.
