Infusion of contrast medium through the urogenital pore permitted visualisation of both the urethra and genital duct. The genital duct is located ventrally to the urinary system and, in a lateral projection, its course is easily detectable until the area of the gonads (Figure 5).
In both the marine species studied the genital duct and urinary duct exit as two separate ducts into two separate pores.
In 86 cases out of the 95 females that contained one tip in their genitalia, the tip was placed inside the spermatheca, and in nine cases the tip was located in the genital duct. Thus, we estimated the probability for the first tip in the female's genitalia to enter the spermatheca as 0.9.
