Final answer:
The equivalent of the puboprostatic and vesicosacral ligament thickening in males in females is the uterosacral ligament.
Step-by-step explanation:
If the parietal pelvic fascia thickening in males is the puboprostatic and vesicosacral ligament, the similar thickening in females is the uterosacral ligament (C). The uterosacral ligament helps stabilize the uterus posteriorly by its connection from the cervix to the pelvic wall. This structure corresponds to the male puboprostatic ligament in function, providing support to the pelvic organs and maintaining their correct position within the abdominopelvic cavity.
