Task: Answer Verification
Input (English): Question: Does urinary concentration exclusively rely on plasma vasopressin . A study between genders . Gender and diurnal urine regulation?
Answer: Similar urinary flows and osmolalities are associated with levels of plasma vasopressin and renal PGE2, which are higher in males than in females. Oxytocin does not seem to play a role in the diurnal urine formation, whereas prostaglandin E2 could represent a mediator of the gender difference, not only as a mediator of the vasopressin response, but also as an independent factor. These findings need further elucidation.
Output (English): no
