The boar reproductive system

Abstract

The boar reproductive system consists of six different structures (testes, epididymis, deferent ducts, urethra, accessory sex glands, and penis) and the main function is the production and the ejaculation of semen. The two testes are the male gonads and their functions are sperm production and secretion of hormones. The main functions of two epididymis are: sperm transport, sperm maturation, and sperm storage. The sperm maturation is a complex process after which sperm acquire progressive motility and fertilizing ability. Male accessory sex glands include: the seminal vesicles, the prostate, and the bulbourethral glands (Cowper's glands). These exocrine glands release their secretion into the urethra and their secretory activity is androgen-dependent. The noncellular fraction of the ejaculate (seminal plasma) is mainly composed of fluids from the accessory sex glands.
