Male Reproductive Anatomy, Part 1

It is important to know the anatomy of the male reproductive system, is to review both and select animals for breeding to make good management of breeding  moment.

Scrotum and Testicles

The scrotum is a bag in which are found inside the testicles. It is located in the region below the anus. It has a pendulum as in other animal species (cattle, sheep). Okay manteniene attached and testicles close to the body of the male. This position is disadvantageous because problems tend to suffer strokes or injuries in fights.

Both testicles have dropped into the scrotum from the abdominal cavity during the first month of life. These have an oval shape, and in an adult male can measure from 4 to 6 cm long and about 2.5 to 3.5 cm wide. When they are a year old, the length is 1.0 to 1.5 cm.

The testicles play a key role, being responsible for sperm production

Epididymis and vas deferens

The epididymis is next (and attached) to the testicle. Acts as backup location and maturation of sperm. During ejaculation epididymal sperm passes to the vas. Then into the urethra and eventually abroad.

Accessory glands

Accessory glands (prostate and urethral bublbo) are located in the pelvis and shoulders above the rest of the male genital tract. These glands secrete fluids that give volume, nutrients and stability semen.
