Urinary Vasopressin in Male Infertility

In 10 healthy but infertile men, semen analysis and urinary vasopressin levels were evaluated and correlated. A significant correlation was observed between sperm count and urinary vasopressin (r-0.86). Similar correlation was seen between sperm motility and urinary vasopressin (r-0.83). It thus appears that higher levels of vasopressin are associated with aspermia and oligozoospermia.
