Summary. The contractility of the cauda epididymidis and vas deferens and the movement of stained paraffin oil droplets deposited in the vas lumen were, respectively, registered and followed visually in rats electrically induced to ejaculate. Each electrical stimulation produced an abrupt contraction in the cauda epididymidis and in the middle and distal portions of the vas deferens. With the first electrical stimulations the paraffin oil droplets deposited in the proximal and middle portions of the vas deferens flowed towards the cauda epididymidis. At the moment of emission only the paraffin oil drop deposited in the distal portion of the vas was expelled towards the urethra, appearing in the urethral meatus with the ejaculated solid plug.

Reproduction is committed to supporting researchers in demonstrating the impact of their articles published in the journal.

The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
