Summary. The contractile response of the isolated testicular capsule to acetylcholine, norepinephrine and prostaglandins (A-2, E-1 and F-2α) was related to the age of the rat. Norepinephrine and PGA-2 caused an increased capsular response between 45 and 60 days of age, the time at which spermiogenesis begins. It is suggested that the activity of the testicular capsule is involved in the transport of non-motile spermatozoa from the testis and into the epididymis.

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.
