Accessory Ducts and Glands

 Accessory ducts include:

1. Rete testis

2. Vasa efferentia

3. Epididymis

4. Vas deferens

The seminiferous tubules open into the vasa efferentia through the rete testis.

The vasa efferentia open into the epididymis, which leads to the vas deferens.

The vas deferens opens into the urethra along with a duct from the seminal vesicle called the ejaculatory duct.

The ejaculatory duct stores the sperms and transports them to the outside.

The urethra starts from the urinary bladder, extends through the penis and opens via the urethral meatus.

Accessory glands include:

1. A pair of seminal vesicles

2. Prostate gland

3. A pair of bulbourethral glands

The secretions of these glands make up the seminal plasma, and provide nutrition and a medium of motility to the sperms.
