Yes, ultrasound can detect the presence of ejaculate, which contains sperm, within the uterus.
According to the provided reference, ultrasound imaging can visualize ejaculate within the uterine horn. The reference specifically states:
- "The ejaculate is visible as anechoic fluid within the uterine horn on both images (arrows)." This indicates that the ejaculate appears as a dark, fluid-filled area in the ultrasound image.
Therefore, while ultrasound doesn't directly image the sperm cells themselves, it can detect the seminal fluid or ejaculate containing the sperm within the uterus.
