Ultrasound has many uses in fertility testing. Vaginal probe ultrasound is used extensively to monitor follicles during ovulation induction cycles for IVF and often for stimulated IUI. If daily monitoring is performed until the follicle “ruptures” it can also determine when and if ovulation occurs . Another use is to measure the thickness of the endometrium to confirm that it is developing properly.
Ultrasound is also used to document pregnancy, by visualizing the fetus, as well as detecting early fetal heart motion. It can be used in many different types of abdominal evaluations for fertility such as for ovarian hyperstimulation syndrome (OHSS) and other conditions.
